Abstract

The invention relates to the technical field of roadbed reinforcement, and discloses a composite roadbed structure of bored piles and a construction method thereof. A borehole in the rock formation; a reinforcement body disposed in the borehole; a cushion structure disposed on the upper surface of the reinforcement body; and a filling roadbed disposed on the upper surface of the cushion structure, the method comprising : rolling the basic body of the road; carrying out the drilling operation on the road basic body after rolling; pumping concrete into the borehole; lowering the reinforcement cage into the borehole poured with concrete; laying the cushion structure; on the cushion structure Rolling and laying to fill the roadbed. The bored pile composite subgrade structure has the advantages of preventing post-construction settlement and improving bearing capacity.

Description

technical field [0001] The invention relates to the technical field of roadbed reinforcement, in particular to a composite roadbed structure of bored piles and a construction method thereof. Background technique [0002] For the existing subgrades of railways, municipal roads, wharves and reservoirs, due to the limitations of technical and economic conditions during construction, there are often cases of low filling and compaction standards. After the road or railway is put into operation, the long-term Under vibration or rolling, the existing roadbed is prone to overall or partial settlement and low bearing capacity. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a composite roadbed structure of bored piles and its construction method, so as to solve the problems of the existing roadbed in the prior art that are prone to overall or local settlement and low bearing capacity. [0005] (2) T...
