Hilly and mountainous area reinforcement cage stalagmite pile and construction process thereof

Abstract

The invention discloses a hilly and mountainous area reinforcement cage stalagmite pile and a construction process thereof and belongs to the field of roadbed construction. The hilly and mountainous area reinforcement cage stalagmite pile comprises a reinforcement cage, stones and crushed gravel soil; the reinforcement cage is sleeved into a foundation pit of a soft soil roadbed; and the stones and the crushed gravel soil are both filled into the reinforcement cage. The reinforcement cage stalagmite pile is a composite foundation reinforcing pile made by using rubble and crushed stones as mainmaterials; the construction quality can be effectively guaranteed; the construction time of each reinforcement cage stalagmite pile only needs 40 minutes; the construction speed is high; the soft foundation construction progress can be accelerated; a reinforcement cage stalagmite pile soft foundation treatment process only needs simple reinforcement machining equipment and roadbed filling equipment such as an excavator and a dump truck and does not need to input other special equipment; materials are mainly traditional roadbed use materials such as reinforcements, rubble and crushed stones; requirements on the equipment and the materials are lower; and the construction cost is lower.

Description

Technical field [0001] The invention relates to the field of roadbed construction, in particular to a reinforced cage stalagmite pile in a mountain and heavy hill area and a construction technology thereof. Background technique [0002] As we all know, my country’s soft soil is widely distributed, and because of the poor stability of the roadbed when the highway is built in the soft soil area, it is prone to deformation and settlement, which seriously affects the safety of the highway. Therefore, in the process of highway subgrade construction, the soft subgrade is one of the prominent contradictions that affect the cost of subgrade engineering and the quality of subgrade use. In the process of soft foundation treatment, roadbed engineering generally adopts construction techniques such as dredging and replacement, gravel piles, and plastic drainage boards, and the applicable conditions of various construction techniques are not the same. Based on the current scientific research ...
