Waterproof structure of drainage well and construction method of waterproof structure
The invention provides a drainage well waterproof structure which comprises a plurality of vertical shafts vertically arranged at intervals and a plurality of pipe jacking wells connected to the bottoms of every two adjacent vertical shafts, and the drainage well waterproof structure comprises the steps that inspection wells formed at the joints of the pipe jacking wells and the vertical shafts are constructed, and the top elevation of the inspection wells is higher than that of the pipe jacking wells; the cross section size of the inspection well is larger than that of the vertical well; the enclosure wall encloses the vertical shaft, the top elevation of the enclosure wall is lower than the top elevation of the pipe jacking well, and the pipe jacking well penetrates through the enclosure wall; the water intercepting wall is formed at the top of the enclosure wall in a pouring manner and surrounds the vertical shaft; the water intercepting wall comprises a plurality of bearing sections which are spliced end to end; and the backfill layer is filled among the vertical shaft, the water interception wall and the enclosure wall. Seepage water is blocked through the water intercepting wall, the waterproof effect of the drainage well is improved, the inspection well is arranged at the position where the pipe-jacking well and the vertical connection part are connected, construction personnel can conveniently inspect the drainage condition of the pipe-jacking well, and the pipe-jacking well and the drainage well are prevented from being blocked.
本发明提供了一种排水井的防水结构，排水井包括呈竖直状间隔设置的若干竖井以及连接于相邻的两个竖井底部的若干顶管井，包括：施工形成于顶管井和竖井的连接处的检查井，检查井的顶部标高高于顶管井的顶部标高，检查井的横截面尺寸大于竖井的横截面尺寸；围住竖井的围护壁，围护壁的顶部标高低于顶管井的顶部标高，顶管井穿设于围护壁；浇筑形成于围护壁的顶部且围设于竖井的截水壁，截水壁包括若干首尾拼接的承重节；填充于竖井和截水壁以及围护壁之间的回填层。本发明通过截水壁以阻挡渗透水，提高了排水井的防水效果，通过于顶管井和竖连接的位置设置检查井，方便施工人员检查顶管井的疏水情况，避免顶管井和排水井阻塞。
