Embodiment Construction

[0015] Firstly, the seismic wave method is used to investigate the basalt distribution area, and the reflection and refraction seismic wave method is used comprehensively. Geophysical detection lines are mainly arranged along the sidelines of buildings. Drilling is carried out on the key parts, and the two methods are combined to analyze, and the isopach map of basalt distribution is obtained.

[0016] According to the load and deformation requirements of different buildings (structures) on the construction site, combined with the thickness of the basalt layer and the buried depth, the processing units can be divided into units that can be directly used, units that need to be processed, and non-utilized units.

[0017] For areas where the basalt thickness of the treatment unit is thin (2m

Abstract

The invention discloses a utilizing and reinforcing method for basalt in the Zhanjiang region. The method comprises the steps of: firstly surveying basalt distribution regions through a seismic wave method in combination with drilling, and then processing to reinforce and utilize the basalt in layered distribution in the Zhanjiang region. The method has the advantages that, the basalt can be used as the supporting layer of the natural basis of a building, by using the characteristics, including high intensity and small deformation, of weathered basalt and combining the unique distribution and development laws of the basalt in the Zhanjiang region; the construction investment can be saved, the construction cycle can be shortened, the construction processing is facilitated, the construction difficulty is small, potential danger sources of blasting removal is reduced, and influence to surrounding is also reduced. The method is built based on full knowledge of distribution and development laws of the basalt in the region; since a great deal of basalt is distributed in the Zhanjiang region, particularly Leizhou Peninsula, the method has a certain promotional value.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a basalt utilization reinforcement method. Background technique [0002] Zhanjiang area is a basalt platform landform. The building site is distributed with strongly weathered and moderately weathered basalts of the Huguangyan Formation. The latter has a top elevation of 6.77-10.55m, a thickness of 0.60-10.55m, and an average thickness of 2m. It is called a rock cap structure. Therefore, the rock formation is similar to a hard crust, which has a great influence on the foundation of the construction site. In the past, in similar areas, the foundation schemes used pile foundations and penetrated the basalt layer, and the project cost was high and the construction period was long. Contents of the invention [0003] The purpose of the present invention is to use the layered basalt in the Zhanjiang area as the bearing layer of the natural foundation. Because of it...
