Embodiment

[0021] The height of the side slope 8 in this example is not greater than 12M; there is a building 9 on the top of the side slope, and the distance from the outer wall of the building 9 to the design excavation line 7 of the side slope 8 is not less than 2M; the side slope is sloped according to the design requirements from top to bottom The slope ratio is excavated, and the anchor rod 1 support and the internal drainage treatment of the slope are carried out for every 1.5M excavation height. The system is fully bonded anchor rods, arranged in a determinant, with a horizontal and vertical spacing of 1.5M, an anchor rod inclination of 15 degrees, and the exposed part of the anchor rod 1 enters the range of the concrete cavity 3; internal drainage treatment of the slope body: built-in 100MMPVC drainage flowers The pipe 2, with a spacing of 2-3M, is arranged in a plum blossom shape, and the end is as deep as possible into the enriched part of the groundwater, and the outer side ex...

Abstract

The invention discloses a support method and device for preventing mud rock landslides. A design excavation line is set at the position away from a slope top building outer wall by 2 M or above; during construction, excavation is conducted according to the sloping slope ratio required by the design from top to bottom, excavation is paused every time when excavation is downwards conducted by 1.5 m, temporary anchor rod support is conducted on the layer, and a drainage pipe is driven into a slope body to conduct drainage treatment; downward excavation is conducted while support and drainage are conducted layer by layer till the slope bottom is reached; a foundation trench is dug in the slope bottom, the outer wall of the foundation trench is a concrete pouring body, the foundation trench is filled with mud rock materials obtained after excavation to be compacted; then, a concrete cavity is constructed above the foundation trench in a layering pouring manner, and the cavity is filled with the mud rock materials to be compacted till the slope top is reached; and finally, anchor rods, the drainage pipes and the outer side of the concrete cavity are fixed. According to the support method and device, the structure is simple, the cost is low, little waste slag exists, the safety performance is high, and construction and operation are fast.

Description

technical field [0001] The invention relates to a support method and device for preventing mudstone landslides, and belongs to the technical field of civil support engineering. Background technique [0002] Mudstone is widely distributed in Southwest my country. Mudstone is easy to weather and hydrate. The strength of the weathered mudstone is significantly reduced, and geological disasters such as collapses and shallow landslides are prone to occur. With the rapid development of my country's economy, all kinds of civil engineering projects are now spread throughout the Southwest China, and in the areas of Daxing civil engineering projects, artificial slopes and landslides are unavoidable. Among various civil engineering projects, artificial slope and landslide projects often involve the need to ensure the safety of existing buildings on the top of the slope. Especially for mudstone slopes, which are rocky and non-rock forms, more attention should be paid to ensure the saf...
