Embodiment Construction

[0017] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0018] A construction method for installing an extra-large-diameter reinforced concrete tongue-and-groove pipe, the steps of which are as follows:

[0019] (1) Establish a reference line: After the sand and gravel foundation has been laid and passed the acceptance check, use a total station to release the center line of the pipeline, and set an installation reference line parallel to the center line of the pipeline and 30cm larger than the pipe diameter as the axis deviation of the control pipeline installation. Set a level at the side of the trench to control the installation elevation of the pipeline;

[0020] ⑵. Mechanical equipment in place: Arrange the crane at a position greater than 2.0 meters from the upper edge line of the trench, p...

Abstract

The invention relates to an installation and construction method for a super-large-diameter reinforced concrete rebated pipe. The method comprises the following steps: (1) forming a reference line; (2) putting mechanical equipment in place; (3) performing pipeline treatment; (4) hoisting a pipe into place; (5) jacking the pipe into a bellmouth; (6) adjusting the deviation of a pipe section; (7) fixing the pipe section; (8) circularly carrying out steps (4) to (7) to complete installation of the entire super-large-diameter reinforced concrete rebated pipe. According to the method, the engineering quality and construction progress are ensured effectively, the mechanical construction level is raised, the labor intensity of workers is lowered, and an excavator and a heavy lift are applied to pipeline installation and construction in a matched way in multiple projects. Compared with the conventional construction method, the method has the advantages that the installation progress is increased greatly, and the construction cost is reduced on the premise that the construction quality is ensured. Via practice and exploration in multiple projects, good economic benefit and social benefit are achieved.

Description

technical field [0001] The invention belongs to the field of concrete grooved pipes, in particular to a method for installing and constructing extra-large-diameter reinforced concrete grooved pipes. Background technique [0002] In the construction of municipal road drainage projects, more and more projects are installed with extra-large diameter reinforced concrete grooved pipes. The diameter of extra-large-diameter reinforced concrete grooved pipes is generally φ2400~φ2800mm. The progress and quality of the installation of super-large-diameter reinforced concrete grooved pipes is the key process to ensure the smooth completion of the entire construction project. The current construction method has a long construction period, slow progress, high labor intensity and high construction cost. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a construction method for installing extra-large-dia...
