Plastic drainage board and construction method for soft soil foundation drainage consolidation

Abstract

The invention relates to the field of building construction, in particular to a plastic drainage board and a construction method for soft soil foundation drainage consolidation. The plastic drainage board comprises a drainage bracket and a filter membrane. The drainage bracket is composed of an integrally-formed transverse bracket and multiple vertical brackets. The transverse bracket and the vertical brackets are arranged in a manner that the transverse bracket is perpendicular to and intersects with the vertical brackets. Easy-shearing grooves are formed equidistantly in the vertical brackets. The transverse bracket and the vertical brackets are covered with the filter membrane. The plastic drainage board is steady in structure, great in water diversion and drainage performance, and easyto shear, and saves time and labor; the fracture is smooth; and connection with a follow-up drainage pipe can be conducted beneficially. The plastic drainage board is used and applied in the construction method for soft soil foundation drainage consolidation; by means of adopting the construction method, the project quality of the drainage consolidation construction is better, and the progress isfaster; and thus the requirements of projects with short construction periods and high quality requirements are satisfied.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a plastic drainage board and a soft soil foundation drainage consolidation. Background technique [0002] In construction, the requirements for the soil quality of the foundation are relatively strict, and the soil quality with too soft soil, high water content, large void ratio or high compressibility is relatively poor in engineering. Without drainage and consolidation of the foundation, the risk of building subsidence or even collapse is very high. In order to eliminate this hidden danger, when building construction on this soft soil, it is often necessary to carry out drainage and consolidation construction, in which a plastic drainage board is required for vertical water diversion and drainage. Later, it needs to be cut manually, and the structure of the plastic drainage board that is easy to cut is relatively poor; because the plastic drainage...

Problems solved by technology

In order to eliminate this kind of hidden danger, when carrying out construction on such soft soil, it is often necessary to carry out drainage consolidation construction. Among them, it is necessary to use plastic drainage boards for water diversion and drainage in the vertical direction. Finally, it needs to be cut manually, and the structure of the plastic drainage board that is easy to cut is relatively poor; because the plastic drainage board needs to bear great pressure underground, the structure of the plastic drainage board should have high strength and compressive capacity, but it is not easy to cut Although the structure of the plastic drainage board is relatively good, the construction is relatively slow, which affects the construction period

In some drainage consolidation construction projects with high quality requirements and tight construction schedules, ordinary plastic drainage boards can no longer meet the requirements
