Construction method of collaborative backfill of hydraulic dynamic compaction machine and flat plate roadpacker

Abstract

The invention relates to the field of roadbed construction, in particular to a construction method of collaborative backfill of a hydraulic dynamic compaction machine and a flat plate roadpacker. Theprocess of collaborative backfill includes the following steps of check before backfill; backfill in layers and preliminary compaction; high-speed hydraulic dynamic compaction; detection, wherein in the step of high-speed hydraulic dynamic compaction, a bridge abutment back, a culvert table back, a retaining wall back and a pipe network groove are compacted in sequence. Compared with a traditionalmethod, the advantages that part movement is more flexible, the efficiency is higher, the consistency of the backfill compaction degree is further guaranteed while the backfill compaction construction quality is guaranteed, the safety performance is higher, and construction is more convenient and reliable are achieved. The flexibility advantage of the construction method is more obvious especially for some regions which are narrow and irregular and have certain depth.

Description

technical field [0001] The design of the present invention relates to the field of subgrade construction, and in particular to a construction method for backfilling in cooperation between a hydraulic compactor and a flat compactor, specifically, using the dynamic compactor and the compactor to construct the abutment back, culvert abutment, and abutment during subgrade construction. The backfilling of the restricted areas such as the back of the earth wall and the trench of the pipe network is carried out in a coordinated compaction operation. Background technique [0002] Most of the backfill areas of abutment backs, culvert backs, retaining wall backs, and pipe network trenches during subgrade construction are narrow, irregular, and have a certain depth, and for the protection of structures, many large-scale compacted Mechanical equipment cannot be used. In this regard, the most conventional construction measures are to use small compaction machines or manual compaction in...

Problems solved by technology

However, the tamping energy of small machinery and manual tamping is limited, and the construction efficiency is low. At the same time, the quality of backfilling is greatly affected by the operators.

[0003] Therefore, using the conventional backfill compaction method, the construction speed and compaction effect are often unsatisfactory. After a rainy season, the backfill site often has uneven settlement, which affects the safety and comfort of driving.
