Abstract

The invention provides a construction method for capping a non-supported caisson, comprising: setting a supporting corbel; making a prefabricated beam on the top of the caisson; hoisting the prefabricated beam to a required installation position on the caisson and placing it on the supporting corbel, The reserved steel bars at both ends of the prefabricated beam and the vertically reserved steel bars on the well wall are staggered and anchored to each other; when the prefabricated beam is hoisted in place and fixed, the connecting steel parts are connected with the embedded steel plate to form a horizontal grid support platform, and Set up a support plate on the grid support platform, and set rivets on the support plate; bind the steel bar of the caisson roof and connect it with the reserved steel bar on the upper part of the prefabricated beam, pour concrete on the support plate and the joints of the well wall to form the caisson roof To cap the caisson, after the caisson is capped, the connecting steel parts and support plates are retained as a permanent structure. The invention cancels the traditional way of erecting the high formwork steel pipe inside the caisson, eliminates the safety hazard of the support system of the tall formwork, shortens the construction period and reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of capping caissons, and in particular relates to a construction method for capping unsupported caissons with large diameter and large depth. Background technique [0002] In recent years, caisson construction technology has been widely used in bridges, underground engineering, deep foundations of adjacent buildings, municipal engineering, etc. The caisson capping project is one of the most difficult points in the caisson construction, especially in the construction of the top beam and slab of the caisson with large diameter and depth. Large-diameter and large-depth caisson capping usually adopts the method of high formwork support system for cast-in-place construction, or the top beam slab is hoisted in place with a fully prefabricated structure. impact on safety, etc. [0003] The Chinese patent (application number 201911013086.0) discloses a construction method for erecting scaffolding for caisson const...
