Novel roadbed side slope building protecting method and precast concrete blocks therefor

Abstract

The invention discloses a novel roadbed side slope building protecting method and precast concrete blocks for the novel roadbed side slope building protecting method, belonging to the technical field of roadbed engineering. The precast concrete blocks are paved along the surface of a side slope, U-shaped concrete drainage channels are arranged at intervals in the route direction, each precast concrete block is shaped like a regular hexagonal prism, a drainage hole which penetrates through the upper surface and the lower surface of a column body is arranged on each precast concrete block, and the bottoms of the drainage channels are embedded into the side slope. The method comprises the following specific construction steps of: (1) pretreating the side slope: brushing capping mass off from the side slope, filling pit concavity, and punning the surface of the slope, wherein the surface of the slope is required to be flat and smooth; (2) pouring the precast concrete baffle blocks at the foot of the slope, wherein one part of each precast concrete block in the width direction is rooted in a stone paving base, and the other part of each precast concrete block in the width direction is rooted in the side slope; (3) paving a water-seepage cushion layer on the finished surface of the side slope; and (4) paving the precast concrete blocks from bottom to top, wherein the precast concrete blocks and the surface of the slope are in close fit when the precast concrete blocks re paved.

Description

technical field [0001] The invention relates to a roadbed slope protection technology for railways, highways, municipal roads, etc., and belongs to the technical field of roadbed engineering. The invention also relates to a prefabricated concrete block used for roadbed side slope protection. Background technique [0002] Roadbed slope protection is widely used in various roadbed projects such as railways, highways, and municipal roads. Usually, mortar rubble is used to protect the roadbed slope. When masonry rubble is used to protect the embankment slope, during the construction process, due to factors such as lack of building ground materials (gravel) or poor quality of the rubble, it cannot meet the quality requirements of the internal and external beauty of the embankment slope protection, which affects the safety and quality of the project. [0003] In addition, the use of masonry rubble to protect the embankment slope requires a lot of resources such as construction ma...

When masonry rubble is used to protect the embankment slope, during the construction process, due to factors such as lack of building ground materials (rock rubble) or poor quality of the rubble, it cannot meet the quality requirements of the interior and exterior beauty of the embankment slope protection, which affects the safety and quality of the project.

[0003] In addition, the use of masonry rubble to protect the embankment slope requires a lot of resources such as construction manpower and materials, long construction period, high cost, and difficult construction quality control. Moreover, cement masonry is mixed on site to build rubble, which can easily cause water and water pollution. Environmental pollution such as cultivated land
