Fabricated rubble slope surface protection structure and construction method

Abstract

The invention discloses a fabricated rubble slope surface protection structure and a construction method. The protection structure comprises a slope soil body, wherein an assembly type masonry framework is fixed to the slope surface of the slope soil body, the masonry framework is engaged and fixed through an assembly structure from the slope surface to the slope toe, mortar rubble is laid in the masonry framework, a slope toe embedded structural member is arranged at the slope toe of the slope soil body, and the bottom of the masonry framework is supported by the slope toe embedded structural member. The construction method comprises the following steps of cleaning the side slope; arranging a bottom layer structure; hoisting the fabricated masonry framework; implanting an anchor rod; laying the fabricated masonry framework; constructing a water stop seam; and controlling the slope deformation. According to the fabricated rubble slope surface protection structure and the construction method, raw stones are effectively used for reinforcing the slope surface, compared with a pure lattice slope protection method, the gravity back pressure effect is achieved, the raw stones can be preferably used, and waste residues generated during field excavation are reduced. Compared with an integral slope protection structure, the fabricated slope protection construction is adopted; and compared with the mortar rubble, the construction can be accelerated, and the construction period is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a prefabricated rubble side slope protection structure and a construction method. Background technique [0002] At present, the researches on slope freezing damage mostly focus on the distribution of slope permafrost layer and the influence of rock and soil freezing and thawing on slope stability. At present, the common slope protection structures of railways and highways mainly include mortar rubble, arched skeleton, concrete lattice and other forms. The research on the durability of slope protection structures mainly involves the impact of chloride ion erosion and freeze-thaw cycles on the durability of concrete structures, but the current main focus is on the durability characteristics of simple concrete structures. The freezing damage of slope protection structures in northern mountainous areas of my country is closely related to the natural environment...

Problems solved by technology

[0003] The traditional slope protection structure and construction methods require a huge amount of engineering and low degree of mechanization, resulting in a long construction period; especially for mountain road construction, due to inconvenient transportation, it is difficult to transport materials to the construction site, requiring a lot of manpower, resulting in construction extremely inefficient

[0004] In view of the fact that the traditional slope protection structure and construction method are not compatible with the development requirements of engineering construction, it is necessary to develop a set of slope protection structure and construction method with high construction efficiency and low labor consumption to solve the problem of slope protection. The problem that the surface protection structure project seriously lags behind the construction of the project
