Description
Technical field
The utility model relates to a kind of antislide pile, especially relates to a kind of draining antislide pile for reinforcing slope, bank, storehouse, massif side slope.
Background technology
The area of China's mountain and hill accounts for 2/3 of territory total area, and geological disaster takes place frequently, and wherein landslide disaster is one of topmost geological disaster.Along with the development of China's economic society, increasing economic activity launches in the mountain area, such as building the road, open a mine, build dam etc., is main slope geological problem take the landslide with regard to relating to a large amount of like this.Landslide disaster impacts usually for the economic construction of industrial and agricultural production and country, even causes heavy losses for people's lives and properties.Therefore, carry out the Landslide Remedial Measures on Some research of system, slope reinforcement retaining structure reasonable in design has important practical meaning in engineering to control and the geological environment protection of China's geological disaster.
Landslide control is the geotechnical engineering problems of a complexity, the main Skid Resistance Measures that uses at landslide control engineering at present is antislide pile, antislide pile is a kind ofly to pass through gliding mass and at the structure of the certain depth place anchoring of sliding bed, the Thrust of Landslide effect on top is passed to stable sliding bed by antislide pile, reaching the purpose of Landslide, is one of technical measures commonly used in the landslide control.Yet the antislide pile that adopts in the engineering at present still has the following disadvantages: (1) agent on crack resistance of concrete sliding pile is because concrete is easy to crack, and tensile property is poor; Reinforced concrete anti-slide pile or antiskid piling bar are although tensile property is strengthened Chang Yingang muscle corrosion and lose supporting capacity (particularly for many landslides and comparatively general province, city, the place of reinforcement corrosion phenomenon, often deeply hurting); (2) be comprised of steel concrete in view of present antislide pile, transmission coefficient is often 10
-7Below the m/s, and sliding mass leading edge transmission coefficient is larger, often greater than 10
-5M/s, therefore, the relative gliding mass of reinforced concrete anti-slide pile is water barrier, the result is that the intensive campshed of sloping body middle and lower part has formed virtually vertically every oozing wall, stop from sloping body trailing edge and compile and the underground water that comes can not get timely drainage, and then raised the groundwater table of sloping body middle front part, increased the saturation ratio of the sliding mass regional area soil body, cause gliding mass gravity to increase, sliding comprehensive cohesion and the angle of internal friction be with descends, and anti-skid power reduces, and sliding force increases, increased to a certain extent the potential danger on landslide, the comprehensive antiskid effect of antislide pile reduces.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of draining antislide pile that integrates antiskid and draining and improved flexural strength.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of draining antislide pile, comprise the cylindrical shape pile body, be provided with cylindrical cavity in the described pile body, be evenly equipped with vertically several treatment holes on the described pile body, be provided with gutter in the described cylindrical cavity, the gap of described cylindrical cavity is filled with rubble, and the delivery port of described gutter is connected with the vacuum pump of outside.
Be vertically arranged with several carbon fibre bars in the pile lining of described pile body, described carbon fibre bar evenly distributes along the pile body cross-sectional periphery.Both satisfy the tensile property requirement, improved again the antislide pile corrosion resistance.
The both sides nose end of described treatment hole is enclosed with for the geotextiles that oppositely filters out impurities.Nose end is made loaded filter and with the geotextiles wrapping, can effectively be prevented and treated obstruction, so that antislide pile has possessed drainage channel;
Described treatment hole radially is interspersed along pile body.
Described vacuum pump is connected with the valve that is used for controlling the gutter pump-out.
Described pile body adopts concrete material to be made.
Compared with prior art, the utility model has the advantage of: a kind of draining antislide pile of the utility model, comprise the cylindrical shape pile body, be provided with cylindrical cavity in the pile body, axially be evenly equipped with several treatment holes along pile body on the pile body, be provided with gutter in the cylindrical cavity, the gap of cylindrical cavity is filled with rubble, and the delivery port of gutter is connected with the vacuum pump of outside, and the pile body cavity is filled up by rubble, this rubble not only can draining but also can have been improved the pile body flexural strength, and its advantage is as follows:
(1) antislide pile has higher bending rigidity: conventional steel reinforced concrete hollow shell pill bending rigidity is low, easy to crack, is difficult to be applied to the slope supporting structure.And the utility model is filled by rubble owing to the pile tube hollow parts, and its bending rigidity is suitable with traditional entity stake, therefore can apply in side slope consolidation projects;
(2) antislide pile possesses drain function: rubble is filled the pile tube hollow parts and is formed the rubble accumulation body, can be used as good drainage channel;
(3) antislide pile has stronger resistance to corrosion: the reinforcing bar with in the alternative traditional antislide pile of fiber-like material, both satisfied the tensile property requirement, and solved again the corrosion of steel bar problem.
In sum, draining antislide pile of the present utility model, a kind of integrate antiskid and draining and can corrosion resistant novel side slope retaining structure, change that traditional antislide pile tensile property is low, the shortcoming of poor permeability, corrosion-resistant, hollow structure also can play a role in the drainage, can reduce the flowing pressure of slope soil, reduce the potential danger on landslide, significantly improve the comprehensive antiskid effect of antislide pile.
