Abstract
A combined supporting structure with anchor cables and cast-in-situ bored piles is applied to slope through cut supporting in areas where digging pile is restricted, and can solve the problems of slope through cut slope collecting and digging pile construction at the same time. The combined supporting structure with the anchor cables and the cast-in-situ bored piles comprises reinforced-concrete cast-in-situ bored piles, a reinforced-concrete top beam, reinforced-concrete middle beams, pile top anchor cables, middle beam anchor cables and soil nails. The reinforced-concrete cast-in-situ bored piles are arranged in a slope through cut side slope rock-soil body along a roadbed in the longitudinal direction at intervals. The reinforced-concrete top beam is arranged on the top portions of the cast-in-situ bored piles and is fixedly combined with the cast-in-situ bored piles. The reinforced-concrete middle beams are arranged on the outer sides of the middle-upper portions of the cast-in-situ bored piles and are fixedly combined with the cast-in-situ bored piles. One end of each pile top anchor cable is anchored at a joint point of the reinforced-concrete top beam and each cast-in-situ bored pile, and the other end of each pile top anchor cable is anchored in the side slope rock-soil body. One end of each middle beam anchor cable is anchored on each reinforced-concrete middle beam, and the other end of each middle beam anchor cable is anchored in the side slope rock-soil body. The soil nails are arranged at intervals in the transverse direction and the vertical direction between each two adjacent cast-in-situ bored piles.
Description
Technical field
The utility model master relates to the retaining structure that railway, highway etc. are built the slope cutting, and particularly a kind of propping up at the slope in the restricted area of hole digging pile cutting blocked employed anchor cable bored pile combination retaining structure.
Background technology
The high-grade railway in mountain area begins to build in a large number, the slope cutting is more and more, and safety problem is more and more important, the safety issue of hole digging pile is always controversial, in many countries and regions even forbid to use hole digging pile, in addition, labour cost is also more and more higher, can predict in the future, it is the trend of engineering development that drilled pile replaces hole digging pile.Slope cutting when hole digging pile is restricted arranges retaining structure, because the Pile footpath is little, Its ultimate bearing capacity is not enough and distortion is larger, therefore in the urgent need to a kind of novel subgrade support retainer structure.
The utility model content
Technical problem to be solved in the utility model provides a kind of anchor cable bored pile combination retaining structure, and the slope cutting that applies to the restricted area of hole digging pile props up to be blocked, and can solve simultaneously slope cutting closing slope and excavation pile construction problem.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Anchor cable bored pile combination retaining structure of the present utility model, it is characterized in that it comprises: reinforced concrete bored pile is arranged in the cut slope Rock And Soil of slope along roadbed longitudinal separation; Steel concrete Guan Liang is arranged at bored pile top and fixed with it; Reinforced concrete waist rail is arranged at the outside, bored pile middle and upper part and fixed with it; Stake top anchor cable, an end is anchored in steel concrete Guan Liang and bored pile Nodes, and the other end is anchored in the slope ground body; Waist rail anchor cable, an end are anchored on the reinforced concrete waist rail between adjacent two bored piles, and the other end is anchored in the slope ground body; Soil nailing, domatic horizontal, vertical interval arranges between adjacent two bored piles.
The beneficial effects of the utility model are that the slope cutting that applies to the restricted area of hole digging pile props up to be blocked, and can solve simultaneously slope cutting closing slope and excavation pile construction problem; Structure stress is simply clear and definite, and construction safety, globality are strong, good stability, meets the trend of engineering development, has wide popularizing application prospect.
Description of drawings
This manual comprises following three width of cloth accompanying drawings:

Component shown in the figure, toponym and corresponding mark: reinforced concrete bored pile 1, steel concrete hat beam 2, reinforced concrete waist rail 3, stake top anchor cable 4, waist rail anchor cable 5, soil nailing 6.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, Fig. 2 and Fig. 3, anchor cable bored pile combination retaining structure of the present utility model comprises: reinforced concrete bored pile 1 is arranged in the cut slope Rock And Soil of slope along roadbed longitudinal separation; Steel concrete hat beam 2 is arranged at bored pile 1 top and fixed with it; Reinforced concrete waist rail 3 is arranged at the outside, bored pile 1 middle and upper part and fixed with it; Stake top anchor cable 4, one ends are anchored in steel concrete hat beam 2 and bored pile 1 Nodes, and the other end is anchored in the slope ground body; Waist rail anchor cable 5, one ends are anchored on the reinforced concrete waist rail 3 between adjacent two bored piles 1, and the other end is anchored in the slope ground body; Soil nailing 6, domatic horizontal, vertical interval arranges between adjacent two bored piles 1.This combination retaining structure utilizes reinforced concrete bored pile 1 to solve the excavation pile construction difficult problem, utilize steel concrete hat beam 2 to improve reinforced concrete bored pile 1 globality and rigidity, utilize stake top anchor cable 4 and waist rail anchor cable 5 to improve Its ultimate bearing capacity and the control horizontal distortion of combining structure, have that globality is strong, good stability, stressed simple clear and definite, and the advantages such as safety and environmental protection, the trend that meets engineering development has wide popularizing application prospect.
Described steel concrete hat beam 2 arranges the shrinkage joint every 15～20m one in the middle of two reinforced concrete bored piles 1.Domaticly between adjacent two bored piles 1 every 2～3m one spilled water hole is set, spilled water hole is blossom type and lays.
Some principles of the above the utility model anchor cable bored pile combination retaining structure that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify that might be utilized and equivalent all belong to the claim claim that the utility model is applied for.
