Building foundation pit slope protection system and method

Abstract

The invention relates to a building foundation pit slope protection system. The building foundation pit slope protection system comprises protection stand columns, positioning plates, protection net plates, adjusting rods, a water collection tray, a drainage pipe, sliding blocks and a drainage pump, wherein the front end surfaces of the positioning plates are hinged to the upper end surfaces of the protection stand columns; every two adjacent positioning plates are connected through the corresponding adjusting rod; every two adjacent protection stand columns are connected through the corresponding protection net plate; the lower end surfaces of the protection stand columns are embedded in the water collection tray and are connected with the bottom of the water collection tray; the water collection tray communicates with the drainage pipe through a flow guide opening; and the drainage pump is connected with the positioning plate surface. A use method of the building foundation pit slope protection system comprises three steps of protection surface presetting, foundation pit protection and foundation pit drainage protection. The system provided by the invention is simple in structure, flexible and convenient to construct and use and good in universality, and on one hand, slope protection and foundation pit excavation can be performed synchronously; and on the other hand, due to good local drainage capacity, accumulated water in the foundation pit can be efficiently, fast and comprehensively drained.

[0002] In building construction, in order to meet the needs of foundation pit slope protection, various structural types of protective equipment have been developed, such as "a mesh-type foundation pit protection fence" with the patent application number "2016104132579", the patent The application number is "2017111752142" for "a high-safety foundation pit protection bracket" and the patent application is "2017209825437" for "a foundation pit safety protection device based on municipal road engineering". Although these slope protection equipment can It meets the needs of actual construction and slope protection operations. However, in actual use, on the one hand, there are different degrees of poor flexibility of the equipment mechanism. While it is difficult to effectively meet the needs of foundation pit protection operations at different construction sites, it is also impossible to excavate and construct according to the foundation pit. and foundation pit structure changes to flexibly adjust the structure of protective equipment, which seriously affects the reliability and flexibility of foundation pit protection operations, and increases the risk of accidents such as slope collapse during basic construction; on the other hand, the currently used During the operation of the slope protection equipment, the construction labor intensity of the protective equipment used is high, the installation and positioning work efficiency is low, and after the foundation pit positioning is completed, it is often impossible to carry out effective subsequent use, resulting in the labor of the current foundation pit protection work. Intensity, low work efficiency and high cost of protection operations, serious waste of materials

[0003] In addition, in the traditional foundation pit slope protection operation, only the structural strength of the slope can be strengthened and the collapse can be prevented. , the traditional foundation pit protection equipment does not have the ability to drain water, resulting in the accumulation of water in the foundation pit is often unable to drain the water, which seriously affects the normal construction, and the bottom and side walls of the foundation pit are soaked, resulting in the structure of the foundation pit and the foundation. The equipment in the pit is damaged, which seriously affects the efficiency, quality and safety of the foundation pit construction operation. To solve this problem, the current method is to temporarily add drainage pump equipment for emergency drainage. Although the purpose of foundation pit drainage can be achieved to a certain degree, but The installation and adjustment efficiency of the drainage system is low, and it is impossible to achieve uniform and comprehensive drainage in the foundation pit
