Newly-connected pipeline tool for old inspection well and construction method of newly-connected pipeline tool
The invention discloses a newly-connected pipeline tool for an old inspection well and a construction method. The newly-connected pipeline tool comprises an inner clamping plate, an outer clamping plate and a positioning mechanism. The inner clamping plate is composed of a vertical plate, a fixing rod, a positioning ring and a lantern ring. The outer clamping plate is a vertical plate, an open hole is formed in the middle of the outer clamping plate, a through hole is formed in the outer clamping plate and connected with a slurry conveying pipeline, the slurry conveying pipeline is connected to a concrete slurry conveying pump, and the diameter of the open hole of the outer clamping plate is larger than the outer diameter of a newly-connected pipeline. The positioning mechanism comprises an outer clamping plate positioning mechanism and a pipeline positioning mechanism, and a vertical plate of the inner clamping plate and a vertical plate of the outer clamping plate correspondingly abut against and are arranged on the inner wall and the outer wall of the old inspection well with the well wall provided with the holes. According to the invention, the concrete is extruded to fill an uneven part of the hole, so that the water leakage of gaps is avoided; in the rectification construction process, the newly-connected pipeline is fixed all the time, unhardened concrete is not affected, and no gap is generated between the periphery of the side wall of the pipeline and the concrete; and the vertical plate of the inner clamping plate can enable new concrete on the well wall to be smooth, and construction workers do not need to enter the inspection well.
本发明公开了一种用于旧检查井新接管道工具及施工方法，包括内夹板、外夹板、定位机构。内夹板由竖直板、固定杆、定位圈及套环组成；外夹板为竖直板，中间设置有开孔，外夹板上设置有通孔，通孔连接有输浆管道，输浆管道连接到混凝土输浆泵上，外夹板的开孔直径大于新接管道外径；定位机构包括外夹板定位机构和管道定位机构，内夹板的竖直板和外夹板的竖直板分别紧靠并置于井壁有开孔旧检查井的内壁和外壁上。本发明中混凝土受到挤压而填满开孔的凹凸不平处，避免缝隙漏水；在整改施工过程中，新接管道始终被固定，不影响未硬化混凝土，管道边壁周围与混凝土之间不产生缝隙；内夹板的竖直板能够使井壁上新混凝土平整，不需要施工员进入检查井。
