Problems solved by technology
The steel cylinder and the special pipe joint can only be welded on one side in the steel cylinder. If the alignment is not strictly controlled, and the internal construction space is narrow, the welding quality will be affected or even impossible to weld

Embodiment Construction
[0050] In the following, the present invention will be more clearly and completely described by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.
[0051] like Figure 1 to Figure 7 As shown, the present embodiment provides a construction method for pipe jacking riding wells, which includes the following steps:
[0052] S1. Excavate the pipe jacking joint 4 provided with the outer steel plate 5 and expose the pipe jacking joint 4 to the outside, and measure and verify the basic information such as the size and positioning of the outer steel plate 5;
[0053] S2. Hoist the steel cylinder into the foundation pit, and align it with the outsourcing steel plate 5 on the pipe jacking joint 4, and connect the steel cylinder and the outsourcing steel plate 5;
[0054] S3, pouring concrete in the steel cylinder;
[0055] S4. Build a brick well shaft and a complete set of anti-settling ...

The invention discloses a construction method for a pipe-jacking riding well, which comprises the following steps: S1. Excavating a pipe-jacking joint provided with an outsourcing steel plate and exposing the pipe-jacking joint to the outside, measuring and verifying the size of the outsourcing steel plate, positioning and other basic information; S2, hoist the steel cylinder into the foundation pit, and align it with the outsourcing steel plate on the pipe jacking joint, and connect the steel cylinder and the outsourcing steel plate; S3, pour concrete; S4, construct the brick well shaft and complete sets The anti-settling manhole cover seat cover system; S5, backfill the foundation pit, compact the backfill soil, and simultaneously remove the foundation pit support system and surrounding protection piles. By excavating the pipe jacking joints equipped with outsourcing steel plates to the leaking state, it is very convenient to align the steel cylinder and outsourcing steel plates, and there is no disturbance to the pipeline foundation, and there is no need to construct an inspection well floor at the bottom of the pipeline.
Description
technical field [0001] The invention relates to the technical field of matching design for pipe jacking, in particular to a construction method for pipe jacking riding wells. Background technique [0002] Pipe jacking is often used as one of the main methods for laying municipal sewage pipes and rainwater pipes. As a typical trenchless pipeline construction method, pipe jacking construction has the advantages of long jacking distance and little interference to the ground. It is a fast and economical pipeline laying method. In the layout of municipal drainage pipelines, in order to maintain or overhaul the pipelines during normal use, inspection wells are usually arranged at intervals of 30m to 40m along the direction of the pipeline. This type of inspection well is generally constructed after the pipe jacking construction is completed. [0003] According to the diameter and buried depth of pipe jacking, there are generally two construction methods for inspection wells: one...
