Air bag type dewatering well casing pipe and construction method of foundation at dewatering well joint
The invention discloses an air bag type dewatering well casing pipe and a construction method of a foundation at a dewatering well node, the air bag type dewatering well casing pipe comprises an annular main air bag which is an annular body in an inverted circular truncated cone shape; the multiple annular auxiliary air bags communicate with the annular main air bag and are distributed on the periphery of the annular main air bag in a surrounding mode at equal intervals; the pull ring is arranged on the inner wall of the annular main air bag; the air inlet valve is arranged on the annular main air bag; and the exhaust valve is arranged on the annular main air bag. The air bag type dewatering well casing pipe is small in self weight, convenient to carry and low in transportation cost; the water stopping function is achieved, and the leakage risk is reduced; when toppling occurs, strike accidents cannot occur, and the construction safety is improved; when foundation construction is carried out on the dewatering well joints, the meshing performance with later-stage concrete is good; and therefore, the engineering cost is reduced, and the energy-saving and environment-friendly effects are also achieved.
本发明公开了一种气囊式降水井套管、降水井节点处基础的施工方法，该气囊式降水井套管，包括：环状主气囊，所述环状主气囊为倒置的圆台形状的环状体；环状副气囊，为与所述环状主气囊连通的多个，等间隔环绕分布设置在所述环状主气囊的外围；拉环，设置在所述环状主气囊的内壁上；进气阀，设置在所述环状主气囊上；排气阀，设置在所述环状主气囊上。本发明的气囊式降水井套管自重小，便于搬运、运输成本低；具有止水功能，降低了渗漏风险；发生倾倒时不会对出现打击事故，提高了施工安全；对降水井节点处进行基础施工时，与后期的混凝土咬合性好；可回收循环再利用，降低了工程成本，还具有节能环保的效果。
