Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] refer to figure 1 , figure 2 and image 3 , the small combined anti-slide pile structure driven into prestressed super-strong concrete pipe pile wall protection of the present invention includes single anti-slide piles 10 arranged at intervals in the sliding body A, and the lower part of the pile body passes through the sliding surface B and enters the bearing layer , which is characterized in that: the single anti-slide pile 10 is composed of a prestressed prestressed high-strength concrete pipe pile 12 and a reinforced concrete inner core 16. The lower part of the prestressed high-strength concrete pipe pile 12 shrinks radially to form a pile tip 11, and the pile body is driven into the ground; the reinforced concrete inner core 16 is poured in the inner hole of the prestressed high-strength concrete pipe pile 12, and consolidated into one....

Abstract

A prestressed super concrete pipe with pile wall-protecting type small composite anti-slide pile structure can greatly improve the construction speed of anti-slide pile and effectively meet the needsof rapid landslide management and landslide emergency treatment. The structure is arranged in a single anti-slide pile of sliding body at intervals, and the lower portion of the single anti-slide pilebody enters a force holding layer through the sliding surface. The single anti-slide pile is composed of a prestressed high-strength concrete pipe pile and a reinforced concrete inner core; the lowerportion of the prestressed high-strength concrete pipe pile is radially contracted to form a pile tip, and the pile body is driven into the stratum. The reinforced concrete inner core is poured in the inner hole of the prestressed high-strength concrete pipe pile and is fixedly connected with the inner hole of the prestressed high-strength concrete pipe pile. The top of each anti-slide pile is fixedly connected with a reinforced concrete connecting member to form a anti-slide unit or a whole row-frame anti-slide structure.

Description

technical field [0001] The invention relates to an anti-slide pile structure, in particular to a pipe pile wall-protecting small combined anti-slide pile structure suitable for emergency quick rescue and long-term reinforcement of landslides, with strong anti-slide ability and good durability. Background technique [0002] Landslide control is a disaster prevention and mitigation project with huge investment, complicated technology and risky construction. my country is a country with serious landslide disasters, and landslides are widely distributed in the Yangtze River Basin, Yunnan-Guizhou River and other places. Landslides often cause damage to roads, railways, and water conservancy projects, seriously threatening the safety of people's lives and property. Landslides can occur on soil slopes as well as rocky slopes. Over the years, in order to ensure the safety of people's lives and properties and ensure the smooth progress of economic construction, the country has spen...
