Embodiment Construction

[0031] The structural features of the present invention will now be described in detail in conjunction with the accompanying drawings.

[0032] see figure 1 , a workpiece for bridge continuous beam web grouting, including a bellows assembly, a connecting pipe 4, a grouting hose 5 and an exhaust pipe 6; the bellows assembly is composed of more than three metal bellows 1; the The metal bellows 1 are vertically arranged in a row, and an exhaust pipe 6 is connected to the upper part of each metal bellows 1, and the air outlet of the exhaust pipe 6 is upward; between the lower parts of adjacent metal bellows 1 The connecting pipe 4 communicates, and the lower part of the outermost metal bellows 1 also communicates with one end of the grouting hose 5, and the other end of the grouting hose 5 is a grouting port.

[0033] Further, the grouting opening of the grouting hose 5 is an oval opening.

[0034] see figure 1 Furthermore, the connection between the metal bellows 1 and the con...

Abstract

The invention provides a workpiece and a construction method for bridge continuous beam web grouting. The problems in existing bridge continuous beam web corrugated pipe grouting are solved. The workpiece comprises a corrugated pipe component formed by at least three metal corrugated pipes. Two adjacent metal corrugated pipes are connected together through a connecting pipe. A grouting hole is formed in the bottom of the radial side wall of a metal corrugated pipe at one end of the corrugated pipe component and is connected with a grouting soft pipe. Exhaust holes are formed in the tops of the metal corrugated pipes and are connected with exhaust pipes. According to the workpiece, construction is convenient, the working period is shortened, materials are saved, and cost is lowered. Meanwhile, grouting quality can be improved, and environment pollution is lowered. According to the construction method, during construction, assembling and arranging of the tools are completed together, the working period can be saved, cost is saved, and the whole mechanical strength of a bridge continuous beam web is guaranteed.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a workpiece and a construction method for grouting the web of a continuous beam of a bridge. Background technique [0002] In the construction of bridge continuous beams, vertical corrugated pipes are often used to grout the webs of bridge continuous beams. Stop filling the corrugated pipe when it is out, block the grouting port and the grouting port, and then grout the next corrugated pipe. The main drawbacks of this are the following: [0003] 1. The grouting operation for the corrugated pipes is carried out one by one after stretching and finishing the rebar. The construction method of grouting the corrugated pipes one by one greatly limits the grouting efficiency of the corrugated pipes and increases the grouting time ; [0004] 2. Whether the grouting operation of the corrugated pipe meets the construction requirements is based on whether there is a large ...
