Problems solved by technology
Therefore, its reliability cannot be matched with the gravity type or inverted slab type retaining wall on the natural foundation, there is a relatively large risk, and it is very likely to cause landslides and landslides during the complicated construction process, which will seriously affect the construction personnel. Great threat to security
[0005] In addition, in many cases of landslides, surface rainwater scouring and soaking lead to excessive soil moisture content, soil quality changes, and cracking and loss are always one of the main factors causing the problem. Whether it is anchor cable type retaining wall or gravity type The retaining wall cannot fundamentally solve this technical problem

Embodiment Construction
[0019] Refer to attached figure 1 And attached figure 2 , along the slope contour of the river, the slope is divided into several contour areas. In this figure, eight retaining beams (such as retaining beam 2) are arranged, and each retaining beam is made of reinforced concrete It is formed by connecting prestressed ground anchors (such as prestressed ground anchor 1) on the same contour line. Since the top three contour areas are on a slope with a large slope, three consecutive Retaining beams. Similarly, in the middle and bottom of the slope, two and three ground retaining beams are respectively arranged continuously because of the large slope. The prestressed ground anchor goes deep into the rock formation of the slope body, and is combined with the retaining beam to fix the soil mass.
[0020] In the middle of the slope, in the contour area with a small slope, three rows of falling wells (such as falling well 4) are arranged along the contour line, and two rows of fall...

The invention discloses a structure for preventing mountain landslide. The structure can effectively and smoothly dredge rainwater or running water on the surface of a slope body into the underground, so that washing and soaking of the overland flow to a soil structure are reduced, and soil keeps steady and firm. The structure comprises soil blocking ground beams which are arranged on the mountain slope in the direction of the contour line, continuous ebbing wells are arranged between the soil blocking ground beams along the contour line, intercepting ditches are arranged to connect openings of the ebbing wells arranged at the same contour line together, the soil blocking ground beams are driven into beck rock through prestressed ground anchors to build anchor points, and reinforced concrete is used for casting the soil blocking ground beams to connect the prestressed ground anchors on the same contour line in series. The structure can be suitable for most mountain landslide conditions, and the technical problem is solved with the smaller work amount and the lower cost.
Description
technical field [0001] The present invention relates to a kind of structure that prevents landslides, specifically the present invention relates to a kind of well pile type structure that prevents landslides. Background technique [0002] Landslide is a common and frequent natural disaster, which can cause damage to embankments, highways, and railway embankments, as well as industrial and civil buildings, and bring great losses to the national economy. The traditional method of controlling soil landslides is to build retaining walls or bury anti-slide piles and anchor piles. Both of them are limited in specific applications due to their own defects. [0003] Anti-slide piles are currently the main supporting devices used to control landslides with large thrust. By setting multiple rows of anti-slide piles in the slide body, the landslide thrust can be resisted in stages to achieve the purpose of landslide control. Defects such as unclear stress and large investment; anchor...
