Flooded hole, hole, collapse, intoxication or choking, electric shock accidents occur. 关键字: 人工挖孔桩 质量措施 安全措施 淹孔 塌孔 Keywords: manual hole knockout flooded hole pile quality measures security measures falling 引言：大量地下水或地表水流入人工挖孔桩孔内，致使孔内充满积水，孔被淹没

    淹孔，孔内坠物，坍孔，中毒或窒息，触电事故时有发生

    针对上述不安全状况特制定如下措施： 一 安全措施 安全措施如下： 1排水 淹孔

    这种情况发生在大量地下水或地表水流入孔内，致使孔内充满积水，孔被淹没

    对于地表水，主要是暴雨季节，孔周又无挡水措施，且排水不及时所致，尤其晚上不连续作业，更易发生

     为此，应在孔周用砖墙砌成临时挡水结构或堆土将孔口标高抬高，不使地表水流入孔内

    对渗流水，首先要掌握地质资料，有无可能与江河贯通，如果有高透水层，应配置足够的排水设备

    沿海地区如受潮汐影响，还应考虑潮位的升高而需增加必要的设备

    如经计算，确实渗水量很大，必要时可打设隔水钢板桩或进行注泵处理

    大量抽水还应注意两个问题:一是管涌，即在孔底随着渗流水的排出

    有大量细颗粒被带入孔内，使孔内排出工作量增大，甚至靠人工挖土跟不上进土的速度

    二是大量土颗粒的带入，导致孔外地面沉降，危及临近建筑物或地面交通

    为此可适当地回灌一部分水或减少同时施工的挖孔桩数量

     2安全帽 孔内坠物

    这是常常发生的故事

    孔内施工人员必须备带安全帽，孔外应有专人监护，进行垂直运输，需上下呼应，地面上的操作人员应为孔内人员着想，尽可能创造安全的施工条件

    作业临时停止时，在孔口必须有盖子，防止人员从孔口掉入孔内

     3安全培训 坍孔

    最易造身事故

    坍孔原因很多

    开挖面暴露时间过长；每段护圈混凝土分段过高，致使开挖面过高，挖孔被水浸泡，渗水严重等均会造成坍孔

    对于施工人员的培训，以及派有一定挖孔桩经验的操作人员作业是很重要的

    一个有经验的操作工，能准确判断有无能坍孔并采取相应的措施

    当遇到极差土层，来不及支模浇注护圈混凝土时，对这种个别情况，可用钢制护圈替代混凝土护圈，以及达到几十支护

    对于当天已挖完土的该段护圈，必须将混凝土浇注完，不应放到第二天

     4通风 中毒或窒息

    挖孔桩施工前，必须对地层中的有毒气体作充分的调研，尤其是甲烷、一氧化碳、煤气（主要调研附近有无煤气管道）等有毒气体，必要时应带防毒面具进行作业

    当孔内有操作人员作业时，应有足够的、清新的空气送入

    鼓风机最好是电动的，如用柴油作动力，宜对送入孔内的空气先予以过滤，为防万一出现事故，孔内应设置急救电梯，工地上要配制简单有效地吸氧设备

     5绝缘服，绝缘靴 触电事故

    对常用电器、电缆，应经常检查，防止断裂或走电

    操作人员到孔内作业应穿行橡胶靴，杜绝一切触电事故

     二质量保证措施 质量保证措施如下： 1挖土成孔时，孔的垂直度或称每段护圈的同心度应予确保，为此，应由技术熟练的操作工作人员下孔挖土，经常复核孔的中心位置（可由地面吊垂球至孔底）

    护圈的壁厚只能大不能小，也即挖土宁可往外多挖一些，以保证有足够的壁厚

     2竖向钢筋宜上下相扣，犹如发夹相连

    一旦该段护圈外的摩阻减小（当周围地层发生沉降而造成的负摩阻，常会引起摩阻减小），尚可借钢筋的拉力，不致使护圈整体下滑

     3护圈的模板应支护牢靠，不易产生变形

    同时也要便于拆装，有条件时，尽可能用钢模

     4浇注混凝土时宜用插棒或锤来敲击模板，以使混凝土达到密实

    如用振动器振实混凝土，往往会扰动土壤甚至挤出地下水，常使混凝土掉入土块或使混凝土中的水泥浆流失，都会降低混凝土的质量

    为防止每段护圈混凝土接缝处渗水，下段混凝土顶面应超出上段混凝土的底面，也即确保上节混凝土护圈能插入一部分到下段

     5护圈混凝土的模板不能过早拆除，至少要保证一天，使混凝土强度不低于10MPa为好

     6挖孔到设计标高后，应将孔底面层的虚土铲除，必要时要施以夯击

    如是爆破开挖，应将孔底松动的岩石清除，经各方验孔后方可浇注桩体混凝土

    如果周壁土质较好，无大量渗水，最后一段护圈混凝土可不浇注，该段作为桩体一部分与桩体同时浇注，对整根桩的受力性能是有力的

     7桩体混凝土浇注时必须做到大量地下水渗入，混凝土应通过窜筒下到孔底，当不能排除大量渗水时，可用水下灌注混凝土方法施工桩体混凝土（当渗水量超过0.3L/s时，常用此法）

     结束语：此外，在各作业班组进入工地后正式上岗作业前，项目部必须对班组职工进行“三级”安全教育（班组教育、项目部教育、企业安全管理教育），并建立教育记录挡卡；如果由于安全技术交底不清楚、不全面，职工发生工伤事故，必须追究教育或交底人的责任

              Introduction of manual knockout pile quality and safety measures should be a two-pronged approach                Panjin traffic construction co, Ltd  Li Wenqing   Summary: Large inflows of groundwater or surface water Manual knockout Holes in the resulting hole filled with stagnant water, hole was submerged. Flooded hole, hole, collapse, intoxication or choking, electric shock accidents occur. Keywords : Manual knockout Quality safety flooded hole hole collapse Introduction: excessive ground water or surface water inflow Manual knockout Holes in the resulting hole is filled with stagnant water hole was submerged. Flooded hole, hole, collapse, intoxication or suffocation, electric shock accidents occurred frequently. Against insecurity develop the above the following measures: Security measures Security measures are as follows: 1Drainage Flooded hole. This occurs in a large number of groundwater or surface water into the holes in the hole is filled with stagnant water, hole was submerged. For surface water, mainly is the storm season, Kong Zhou was not retaining water, and drainage is not timely, especially lack of continuous operations at night, more likely to occur. To do this, structure about the hole  with brick built temporary retaining water or soil elevation elevation hole, no surface water into the hole. On seepage water, we must first acquire geological information, the possibility and the rivers run through, if you have highly permeable strata, adequate drainage device should be configured. In coastal areas such as under the influence of the tides, you should also consider the rise of tide level and the need for additional equipment necessary for this. If it is calculated, does a high water volume, if necessary, steel sheet pile or injection pump located water treatment. Large pump should also pay attention to two issues : first, piping, that is, at the end of the hole as the discharge of seepage water. There are a large number of fine particles are brought into the holes in the hole out of the increased workload, or even by artificial excavation without aggressive ground speed. Second, a large number of soil particles into, resulting in land subsidence outside the hole, threatening the nearby structure or surface transportation. This part can properly recharge water or reducing at the same time the number of hole-digging pile construction. 2Safety helmet Hole. This story is often occur. Hole construction personnel must be brought up in a helmet, outside the hole should have the specialist care, vertical transportation, you echoed up and down, action should be a hole in the personnel on the ground, as far as possible creating safe conditions of construction. When the job temporarily stopped, in a orifice must have a lid to prevent people from opening out into the hole. 3Security training The collapse. Most likely to cause personal injury. Many causes collapse. Face exposed for too long concrete segment of each paragraph separator is too high, which face high, digging holes is immersed in water, water will cause a collapse such as serious. For the training of construction workers, have some hole-digging pile and experience of the operator's job is very important. An experienced operator can determine accurately the inability to collapse and take the appropriate measures. When it comes to very poor soil, too late to die when concrete pouring retaining ring, for this particular case, available steel retaining ring instead of concrete retaining ring, as well as at dozens of support. Have dug up soil of the ring the same day, you must set the concrete pouring out, should not be put into the next day. 4Ventilation Poisoning or choking. Before digging hole pile construction, must be a full investigation of the formation of toxic gases, in particular methane, carbon monoxide, gas (no gas pipe near the main research) and other toxic gases, necessary, operation with gas masks. When the holes have operator jobs, there should be adequate, clean air into. Best blower is electric, diesel power, should be fed into the hole on the air to be filtered, for the event of an accident prevention, holes should be set first aid elevator, site preparation on simple and effective oxygen equipment. 5Insulated clothing, boots Electric shock accident. For commonly used appliances, cable, should be inspected regularly to prevent breakage or go electric. Operations staff to the holes in the job through rubber boots, no electric shock accident. B quality assurance measures Quality assurance measures are as follows: 1When digging into the hole, the verticality of the hole or retaining ring of concentric degree of each paragraph should be to ensure that, to that end, hole digging under the skilled operations staff should be, regular review of hole Center location (by hanging vertical ground ball to the end of the hole). Separator thickness only cannot be small, or digging out would rather dig a little more, to ensure that there are sufficient wall thickness. 2Up and down vertical reinforcing steel bar should be interwoven, as if it were attached to hair clips. Once the nurse outside of the circle friction reduces the paragraph (when the surrounding ground settlement occurred as a result of negative frictional resistance, often causing friction reducing), can take tension of steel bars, no separator overall decline. 3Separator template should support the ideas, not easily deformed. As well as to facilitate disassembly and Assembly, when steel die as possible. 4Pour concrete up to with a plunger or a hammer to tap the template, to the concrete to achieve compactness. Such as vibrators inspires the solid concrete, may be disturbed soils, or even out of the groundwater industry often push into kindling in concrete or concrete out of the cement paste loss will reduce the quality of concrete. Per paragraph separator to prevent water seepage in concrete joints, lower concrete of concrete on top should go beyond the bottom, ensuring that concrete retaining ring part can be inserted on to the next paragraph. 5Separator templates cannot be prematurely demolition of concrete, to ensure at least one day, the concrete strength of not less than 10MPaFor good. 6After digging to a design elevation, Virtual Earth layers the underside hole should be forbidden, imposing a tapping when the need arose. Blasting excavation, rock of the hole should be loose at the end of clearing, hole behind the concrete pour pile body inspection. If the peripheral wall of soil better, without the massive seeps, nurse's not pouring concrete in the last paragraph, which as part of the pile and pile body while pouring, behavior is strong on the whole length of the pile. 7Concrete pour pile body must do a lot of groundwater infiltration, concrete by channeling the tube down to the bottom, when large amounts of water cannot be ruled out, and available methods of underwater bored concrete pile in construction of concrete (when the volume of water exceeds 0.31/sShi, commonly used this method).  Conclusion: in addition, the operations team after entering the site before the official posts, project team staff must be on the "third-level" security education (education, enterprise security management team, project, Department of education education), and an education record blocking cards; if your security technology to give the low-down is unclear, incomplete, workers  accident occurred, you must hold the responsibility of education or the low-down. 房屋建造量增加
