Decompression well and dewatering well integrated structure and construction process thereof
The invention discloses a relief well and dewatering well integrated structure and a construction process thereof, and relates to the field of relief well and dewatering well construction. Comprising a pile hole formed in the position, where a foundation pit is to be formed, of the ground, a well wall pipe, a filter and gravel filling materials are arranged in the inner wall of the pile hole, the well wall pipe is made of seamless steel pipes with the diameter of 270 mm and the thickness of 4 mm, quincunx holes are formed in the well pipe on the upper portion of the filter, three layers of 70-mesh steel wire meshes and plastic wire meshes wrap the filter and are bound through 6-mesh lead wires, and a filter pipe is installed on the lower portion of the filter. The gravel filling materials comprise gravel materials, clay balls and medium-coarse sand, the gravel materials with the particle size larger than that of the filter holes are backfilled around the position 5 m from the pipe bottom to the upper portion, the clay balls are backfilled in the middle, and the medium-coarse sand is backfilled around the position 3-6 m from the lower portion of the well mouth. Each well not only can depressurize confined water, but also can depressurize shallow water, various pipelines are reduced, meanwhile, the effects of dewatering and depressurizing can be achieved, the construction cost is saved, and the construction period is also saved.
本发明公开了一种减压井与降水井一体式结构及其施工工艺，涉及减压井与降水井施工领域。包括开设于地面待形成基坑的位置的桩孔，桩孔内壁内设井壁管、滤器和填砾料，井壁管均采用直径为270毫米、厚度为4毫米的无缝钢管，滤器是在上部井管处开设梅花形孔洞，管外包三层70目钢丝网和塑料丝网三层，用6目铅丝往绑扎，下部安装滤管，填砾料包括：砂石料、粘土球和中粗砂，其中管底至上部5m处四周回填粒径大于滤孔的砂石料，中间部位回填粘土球，井口下部3～6m四周回填中粗砂。每口井既能对承压水减压，又能对浅层水进行降水，各种管路减少，同时能达到降水和减压效果，节约了施工成本，也节约了工期。
