Protection method for landslide

Abstract

The invention discloses a protection method for landslide. The protection method comprises the following steps that a, site flattening is conducted, an engineering machine is utilized for flattening a construction site, the inner and outer side height difference in the strip-shaped width direction is smaller than or equal to 5.0 cm, knickpoints and surging slopes in the length direction are eliminated, and surface flattening and gradient smoothness are achieved; and b, surveying and setting out are conducted, a total station is used for conducting surveying and setting out on a mini pile axis point (feature point) according to the pile position planar graph and coordinates provided by a design drawing, a wood pile is nailed at the axis point (feature point) and fixed through cement mortar, the axis point (feature point) serves as a pile positioning and checking reference point, surveying and setting out are conducted on a middle pile through a sighting rod and a steel ruler, a steel bar with the diameter phi being 20 is used for punching, filling of lime is conducted, and full pouring of a mark is conducted. The protection method has the beneficial effects that the mini pile and oblique column cooperative integrated construction manner is adopted, a mini pile system and inter-pile rock soil serve as an integrated structure, the soil layer connecting strength is increased, and the landslide phenomenon is reduced; and construction is simple, the speed is high, cost is low, and rapid treatment of the mountainous area landslide project is facilitated.

Description

technical field [0001] The invention relates to the technical field of landslide construction, in particular to a protection method for landslides. Background technique [0002] In the past, for the sake of economic development, trees were cut down and deep forests were destroyed, resulting in serious soil erosion. When heavy rain occurs, the soil on the slope is prone to landslides. Landslides not only cause huge economic losses, but also threaten the lives of nearby residents. , so for slopes that are prone to landslides, many measures are taken to prevent landslides in different forms. Micro piles generally refer to cast-in-situ piles with a pile diameter of less than 400mm and a slenderness ratio greater than 30, which adopt the construction technology of drilling, strong reinforcement and pressure grouting. Many of the anti-landslide measures in the prior art are costly and require a large amount of manpower and material resources to realize. Moreover, the anti-landsli...
