Problems solved by technology

[0002] Slope protection and retaining works mainly include mortar masonry or concrete anti-slip retaining wall and surface shotcrete support. Concrete or shotcrete requires a long time to reach the design strength; in the preparation stage of the new project, personnel, materials, and mechanical equipment gradually enter the site, and the concrete mixing system and required raw materials are not yet in place, which cannot meet the requirements of concrete. Construction schedule requirements; in addition, masonry masonry construction requires a lot of labor input, while the progress of manual masonry is slow, and there are many safety hazards in the construction process, and its economy and safety are poor

Embodiment Construction

[0027] A construction method of block stone gravity retaining wall, the design points are as follows:

[0028] 1. Material selection:

[0029] The relevant physical properties of the block stone used for the retaining wall need to meet the mechanical construction requirements of the retaining wall, and the general requirement is fresh or weakly weathered rock. The side length of the mining block is required to be 0.5m<a<1.5m.

[0030] 2. Structural design:

[0031] 1. The base of the retaining wall should be horizontal or inclined inward; when it is inclined outward, the base should be designed in a stepped shape.

[0032] 2. The slope ratio of the retaining wall is 1:n=1:(0.3~1.0), the width of the top of the wall is generally 1~2m, the width of the bottom of the wall is slightly larger than the height of the retaining wall, and the slope ratio of the non-air face Determined by stability analysis calculations.

[0033] 3. In addition to the overall anti-sliding and overtu...

Abstract

The invention discloses a rock block gravity-type retaining wall and a construction method thereof. The rock block gravity-type retaining wall comprises a wall body, wherein the wall body is formed by a plurality of rock blocks with transverse length of 0.5-1.5m through building, a gap which is not greater than 20cm exists between left and right two adjacent rock blocks, and fillers fill the gap; the free face slope ratio of the wall body is 1: n =1: (0.3-1), and the top face width of the wall body is 1-2m; the width of the wall body is gradually reduced from bottom to top, and a soil piling area is formed behind the abutment back of the wall body. By using machines to place the rock blocks to quickly form the retaining wall, the needed raw materials are simple, the storage range of the materials is wide, the materials are convenient to obtain, the mechanized level during construction is high, the labor input is small, the construction period is short and the construction cost is relatively smaller.

Description

technical field [0001] The invention relates to a block stone gravity retaining wall and a construction method thereof, which is especially suitable for temporary engineering construction fields in water conservancy and hydropower projects, road and bridge projects, tunnel projects, railway projects, etc. Disaster-prone sections can be used for slope stability protection. Background technique [0002] Slope protection and retaining works mainly include mortar masonry or concrete anti-slip retaining wall and surface shotcrete support. Concrete or shotcrete requires a long time to reach the design strength; in the preparation stage of the new project, personnel, materials, and mechanical equipment gradually enter the site, and the concrete mixing system and required raw materials are not yet in place, which cannot meet the requirements of concrete. Construction schedule requirements; in addition, masonry construction requires a lot of labor input, while the progress of ma...
