Construction device and construction method for riding well
The invention relates to the technical field of pipeline engineering, discloses a construction device and a construction method of a riding well, and adopts an MJS construction method to effectively reduce the influence of soil extrusion, upheaval and the like caused by overhigh in-ground pressure during foundation treatment on the surrounding environment and buildings. And the enclosure structure can be used as a waterproof curtain to ensure the construction safety in the excavation process. The first casing pipe is lowered to the designed depth in advance through the pipe rocking machine, the surrounding soil body can be effectively separated during excavation, the influence on the surrounding environment during excavation is reduced, and the operation safety during welding of the well wall of the riding well and the first casing pipe can be improved. A pouring cavity is formed between the first sleeve and the second sleeve, and the riding well can be formed by pouring concrete into the pouring cavity. The second casing pipe serves as an inner formwork for pouring of the riding well, formwork erecting is reduced, a larger space can be provided for underground operation of constructors, the safety of the constructors is protected, meanwhile, operation time is shortened, construction efficiency is improved, and the construction period is shortened.
本发明涉及管道工程技术领域，公开一种骑马井的施工装置及施工方法，采用MJS工法能够有效减少地基处理时因地内压力过高导致的土体挤压、隆起等对周边环境以及建筑物产生的影响，围护结构可作为止水帷幕确保开挖过程中的施工安全性。通过摇管机将第一套管提前下放至设计深度，开挖时可有效隔断周围土体，减少开挖时对周边环境产生的影响，并能够增加骑马井井壁与第一套管焊接时的作业安全性。第一套管与第二套管之间形成浇筑腔，在浇筑腔内浇筑混凝土即可形成骑马井。第二套管作为骑马井浇筑的内模，减少了支模，能够为施工人员井下作业提供更大的空间，保护施工人员安全，同时缩短作业时间，提高施工效率，进而缩短施工周期。
