Water-sand backfilling construction platform of pipeline in municipal road limited space and method thereof

Abstract

The invention relates to a water-sand backfilling construction platform of a pipeline in a municipal road limited space and a method thereof. The method comprises the following steps of step 1, construction preparation; step 2, sand gravel backfilling; step 3, sand or aggregate chip powder paving; step 4, watering and vibrating; step 5, dewatering and flat plate vibrating; step 6, removing sludgeand impurities; and step 7, compaction degree detection. Through the fluidity of water and the water permeability of the sand gravel are utilized, a layer of sand or aggregate chip powder is spread onthe surface of the backfilled loose gravel, water is poured on the surface of the sand or aggregate chip powder, and the gap of the backfilled gravel stone is filled with sand or stone chips by depending on the infiltration of the water flow and manual vibration action, so that the gravel stone reaches the maximum compactness, the compaction degree of the trench backfilling is guaranteed, the uneven sedimentation caused by insufficient compaction degree of a trench in the later stage is avoided; and the effect of conveniently backfilling the pipeline and the trench with limited operation space is achieved.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a construction platform for water-shaking sand backfilling of pipelines in a confined space of municipal roads and a method thereof. Background technique [0002] Due to its unique technical complexity and interference during the construction process of municipal roads, uneven settlement often occurs on municipal roads, and municipal pipeline construction is an important part of municipal roads, and the quality of its trench backfill directly affects the entire road Therefore, in order to prevent a large amount of manpower and material resources from being spent in the later stage to solve the road diseases in the later period, it is better to eliminate these potential quality hidden dangers in the bud during the construction process. [0003] In the existing technology, the method of backfilling the pipeline by mechanically rolling the foundation requires a large c...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the method of backfilling the pipeline by mechanically rolling the foundation requires a large construction space. In the limited space, it is difficult for large-scale machinery to construct. During the backfilling process, construction personnel are required to follow the length of the pipeline It is very troublesome to vibrate the backfill layer in the same direction
