Problems solved by technology

[0004] In this construction method, the support of the pipeline adopts the prefabricated pipeline base. Since the prefabricated pipeline base is made in advance, it cannot be flexibly adjusted according to the site conditions. The laying of the pipeline is uneven, which will have a certain impact on the subsequent use

Abstract

The invention relates to the technical field of road administration construction, and discloses a construction method for supporting and backfilling drainage pipes in complex sections for highway construction, comprising the following steps: step 1: construction preparation, step 2: excavation of pipe grooves, and step 3: leveling foundation , Step 4: Fabrication of support beam, Step 5: Pipe pre-installation; Step 6: Formwork erection, Step 7: Concrete backfilling, in this scheme, by setting up a laying car, the distance sensor on the laying car cooperates with the first electric telescopic rod to realize the blanking It is convenient to control the quantity, which is beneficial to adjust the uneven road surface, and at the same time, through the infrared mechanism, the position of the material sorting board can be adjusted to ensure that the upper end surface of the support beam is regular, and to achieve a good support effect for the pipeline.

Description

technical field [0001] The invention relates to the field of road administration construction, in particular to a construction method for supporting and backfilling drainage pipes in complex sections for road construction. Background technique [0002] Drainage system is an important infrastructure in modern cities. In the drainage system, the drainage pipe is an essential part. Drainage pipes are pipes that collect and discharge sewage, waste water and rainwater. [0003] The Chinese patent with publication number CN107401207B discloses a construction method of a large-diameter rainwater and sewage pipeline assembled component structure; the construction method mainly includes the following steps: construction preparation, pipe groove excavation, flat foundation, cement solidified layer construction, pipeline foundation Block hoisting, pipeline installation, grouting closed body construction, concrete backfill construction and gravel backfill construction. [0004] In th...
