An assembled recyclable circular work pit with reserved door openings and its construction method

Abstract

An assembled recyclable circular working well with a reserved door opening and its construction method according to the present invention comprise the following steps: (1) functional requirement design of the circular working well; (2) construction of support piles; (3) prefabrication Crown and beam installation; (4) Border protection construction; (5) Earthwork excavation, soil retaining panels, and ring-shaped inner support beams are alternately constructed, and door openings are reserved simultaneously; (6) Ladder installation for entering the circular working well; (7) If the bottom of the circular working well is sealed, the construction of the prefabricated recyclable circular working well with reserved door openings can be completed; (8) After the operation in the well is completed, the retaining panels, annular inner support beams, crown beams and Working well components such as support piles. The prefabricated recyclable circular working well structure system with reserved door openings constructed by the present invention has many advantages such as clear function, safety and quickness, assembled recyclable, reusable, etc. Excavation construction and restoration provides a new method.

Description

technical field [0001] The invention belongs to the field of non-excavation construction and restoration of infrastructure facilities such as water conservancy, municipal administration, heat power, communication, etc., and specifically relates to providing a door opening for the non-excavation construction and restoration of underground pipelines such as water conservancy, municipal administration, heat power, and communication. A prefabricated recyclable circular working pit and a construction method thereof. Background technique [0002] The process of urbanization is accelerating, not only to build a large number of underground infrastructure facilities, but also to face the problem of a large number of old underground pipelines over the service period, which makes the underground pipeline network of many urban roads very complicated, and road surface collapse and safety accidents frequently occur due to damage to underground pipelines . With traffic requirements and th...

Problems solved by technology

At present, regarding the design and construction of working wells, receiving wells and relay rooms, caisson well technology or inverted well technology is still the main choice. Although it is safe and reliable, it has high cost, long construction period, difficulty in sinking, inclination and improper operation. instability accidents, etc.
