A construction method for comprehensively applying piles and vertical geotechnical materials to treat soft foundations of highways

Abstract

The present invention disclosed a construction method of the soft base of comprehensive application piles and vertical geomorphous materials, and introduced the construction process in detail.The implantation position of geomorphology materials is marked with the location of the material; 2) Pile construction setting set setting in the step 1) is performed;Materials and pile connection; 5) The construction of the cushion and the embankment is performed.The invention implants vertical geographical materials in the ground base so that the vertical geographical materials and piles work together. On the basis of the vertical sinking of the ground soil, the vertical geomorphous material is achieved.Further improve the effect of foundation treatment.

Description

technical field [0001] The invention relates to the field of highway soft soil foundation treatment, in particular to a construction method for comprehensively applying piles and vertical geotechnical materials to carry out foundation treatment. Background technique [0002] my country's economically developed areas are mainly concentrated along the river, along the lake or along the coast, and the foundation soil in the above-mentioned areas is mostly silt, silty clay or silty loam. The first expressway was built in China in 1988. With the rapid development of my country's economy, the transportation infrastructure has made great progress. Among them, the construction of expressways on soft soil foundations accounts for a large proportion, and due to the current increasing traffic volume , Many existing highways have already experienced congestion, cannot bear the huge traffic pressure, and are facing widening. At present, expressways such as Guangfo Expressway, Shanghai-Ha...

Problems solved by technology

[0006] In the case of deep soft soil foundation, when using piles for foundation treatment, the bearing layer in the foundation soil will be relatively deep. In order to better control the vertical settlement of the foundation soil, the pile length required is relatively long, which will cause a corresponding increase in the project cost. At the same time, because the pile itself bears the vertical load, the lateral bearing capacity of the pile can be improved, but the lateral bearing capacity of the pile has not been effectively utilized in the project
