Someone develops framed revetment subsequently.But object of searching to the bottom, just in order to resist soil pressure.And soil pressure is except top-down gravity pressure, also has the active earth pressure that level advances, this active force comes from the top soil body of slippage trend forward, the deep soil being then only embedded in front lower place of resistance on the other side can be provided for it, this species resistance comprises generation at the subgrade reaction of soil-baffling structure substrate and the passive earth pressure of front side, and its overall strength depends on the natural compressive strength of foundation soil and the bearing area two indices of innovation soil structure.And retaining wall itself has been the effect of force transferring structure, no matter the change of its structure and intensity size own, key has just required that it can transfer more subgrade reaction and passive earth pressure.And framed revetment, especially the framed revetment of pile foundation load-bearing, self is thin meticulous, and bearing area is limited, only rely on pile top or cushion cap bottom surface the meagre passive earth pressure in meagre subgrade reaction and pile body forward position is provided, be obviously not enough to reach current demand.And in pile foundation construction process, inevitably there is broken pile, floating stake, askew stake phenomenon, more significantly can cut down only meagre resistance.Therefore, its reliability can be mutually not right with the gravity Huo plate-type of the Daoing Xia retaining wall on natural ground, there is greater risk, and probably in complicated work progress, cause landslide landslide accident, causes great threat to constructor's personal safety.
In addition, and in the case of many landslides, surface rain washes away, soak cause that soil moisture content is too high, soil property change, cracking runs off is one of principal element causing problem all the time, below no matter be anchor cable formula retaining wall or gravity retaining wall, all cannot fundamentally solve this technical problem.
Summary of the invention
The object of the invention is to, for the deficiencies in the prior art, a kind of net surface structure preventing landslide of well stake formula is provided, effectively can dredge the domatic rainwater of massif, prevent erosion and soil deterioration, carry out keeping off soil for domatic situation in a distributed manner to reinforce, thus fundamentally solve the problem of landslide.
To achieve these goals, the structure of landslide that prevents provided by the invention is: domatic along layout compacting type gear soil, isohypse direction beam at massif, distributed layout many soil beam can be kept off thus according to landform, between gear soil beam, arrange the overboard well of continuous print along isohypse, and arrange that the opening of same isocontour overboard well couples together by catchwater; Described compacting type gear soil beam gos deep into basement rock with prestressed ground anchor and sets up anchor point, builds grade beam be concatenated by same isocontour prestressed ground anchor with steel concrete.
The aforesaid structure preventing landslide, compacting type gear soil beam can be arranged according to domatic physical features, and particularly large domatic of the gradient can keep off soil beams to reinforce soil layer by continuous intensive layout some compacting types; Aforesaid overboard well also can be arranged according to domatic physical features, little in the gradient and area is larger region can arrange the overboard well of some rows continuously, makes the current on earth's surface fully can be inducted into underground.
The distribution density of aforesaid prestressed ground anchor and overboard well can have more orographic condition and calculate decision.
The aforesaid structure preventing landslide, described overboard well, its structure comprises well stake and prefabricated mozzle, described well stake is negative well stake, the well stake degree of depth at least reaches aquifer, described prefabricated mozzle is infiltration mozzle, and the mozzle tube wall that wherein seeps water has micropore and allows the water outside pipe to infiltrate in pipe.
The aforementioned structure preventing landslide stated, it is characterized in that described catchwater, its section is infundibulate, the current on earth's surface can be collected by catchwater and enter underground by overboard well stream, reduce its flowing on domatic surface, thus reduce current washing away slope structure.
The aforesaid structure preventing landslide, for situations such as the soil is porous, soil moisture content is excessive, the gradient is larger, also can arrange perpendicular to isocontour longitudinal compacting type gear soil beam, keep off soil beam form wire side fixed structure with the compacting type arranged along isohypse.
