Construction method for pipe jacking connection in current well
The invention relates to a construction method for pipe jacking connection in a current well. The construction method is characterized in that an upstream drainage pipe is inserted into an existing current pipeline connected with an upstream well, and a downstream drainage pipe is inserted into an existing current pipeline connected with a downstream well; a dilatation drainage tank is arranged in the current well, and the upstream drainage pipe and the downstream drainage pipe are connected with the dilatation drainage tank; sewage in the current well is discharged, and sludge in the current well is cleared until a water-free operation environment is formed in the current well; and pipe jacking construction relative to the current well is carried out at the set position, and pipe jacking connection in the current well is completed. According to the construction method for pipe jacking connection in the current well, the water-free operation environment can be provided for construction of new pipe jacking connection in the current well, so that the construction is convenient; in the construction process, water does not need to be cut off, and normal use of the current well is not influenced; and due to the good construction environment, the construction period can be effectively shortened, and the construction cost is greatly reduced.
本发明涉及一种现状井内顶管接入施工方法，其特征在于：在现有的与上游井连接的现状管道内插设上游引流管，在现有的与下游井连接的现状管道内插设下游引流管；在现状井内安装扩容疏水箱，进行上游引流管、下游引流管与该扩容疏水箱的连接；然后排出现状井的污水并清理现状井内的淤泥，直至在现状井内形成无水的作业环境；然后在设定位置进行顶管相对于现状井的顶进施工，完成顶管在现状井上的接入。本发明中的现状井内顶管接入施工方法，能为现状井上接入新的顶管施工提供无水的作业环境，使得施工更加方便。并且在施工过程中，无需停水，对现状井的正常使用没有任何影响。由于施工环境好，能够有效缩短施工工期，也大大降低了工程造价。
