Abstract
The utility model discloses a pulling-compressing compound type anchor tension shoring structure in a soil-rock place. A shoring pile is vertically arranged at the bottom of a slope, anchor rod holes are formed in the shoring pile, and a pressure dispersion type anchor rod, a pulling force dispersion type anchor rod and a pulling-compressing combined type anchor rod respectively enter a stable soil body or a rock body in a slope body via the anchor rod holes for fixing the shoring pile. The pressure dispersion type anchor rod can fully utilize the compressive strength of the soil body after grouting to provide stronger anti-pulling force, and the pulling force dispersion type anchor rod can fully utilize the lateral resistance of an anchored body of the rock body to provide stronger friction force, so that the pulling force action on the shoring pile is enhanced and the using quantity of single carrying anchor rods is reduced.
Description
Technical field
The utility model relates to a kind of building engineering construction field supporting and protection structure, and particularly the compound anchor of a kind of Tu Yan place tension and compression draws supporting and protection structure.
Background technology
Often need to carry out supporting to the slope body and process in building engineering construction, have a negative impact to prevent the security of the lives and property that the slope body collapses to construction work or people.Tu Yan (the lower rock of upper soil) combined field, supporting and protection structure commonly used is that anchor draws Row Piles Supporting Structure, this structure is that retaining piles is set at the bottom of the slope, then is fixed in a side of slope body by anchor pole, prevents that the slope body from collapsing.The anchor pole that wherein uses is single bearing-type anchor pole, and during to the single slope body supporting of geological conditions, effect is more satisfactory, for supporting power of the slope body performance of complexity relatively a little less than.Its reason is mainly after the anchor pole load-bearing, and the body of rod namely is in tension state, and is inconsistent because of the native rock mass elastic characteristic around each section of the body of rod, load can not be evenly distributed on the body of rod when the anchor pole load-bearing, serious stress concentration phenomenon can occur or redistribute.As a rule, along with the increase of anchor pole load, reach the distal-most end of the body of rod at load before, the phenomenon that anchoring effect weakens gradually or throws off namely can occur in anchor pole.This phenomenon is in case after occuring, can cause the anchor pole frictional resistance to reduce, thereby greatly reduce supporting and protection structure to the utilization rate of formation strength, and in order to provide stronger pulling force to collapse to prevent the slope body to soldier pile, need to arrange more, longer anchor pole, increase bar muscle consumption, thereby also increased engineering cost.
Summary of the invention
Draw the deficiency of supporting and protection structure in order to solve existing anchor, the utility model provides a kind of Tu Yan place tension and compression composite anchor-rod supporting and protection structure, not only can provide higher frictional resistance to the slope body, and can divide and fill the characteristic properties of utilizing soil layer and rock mass, significantly reduce bar muscle consumption.
The utility model is realized by following technical proposals: it is to be provided with soldier pile in the slope bottom vertical, soldier pile is provided with bolthole, be respectively equipped with pressure dispersing type anchor pole, pulling force decentralized anchor pole and the combined anchor pole of tension and compression in bolthole, wherein the pressure dispersing type anchor pole is respectively equipped with free segment and the anchoring section of several unit, pulling force decentralized anchor pole is respectively equipped with free segment and the anchoring section of several unit, and a section of the combined anchor pole of tension and compression is pulling force decentralized anchor pole, and another section is the pressure dispersing type anchor pole.In the utility model, the compressive resistance that the pressure dispersing type anchor pole can take full advantage of after grouting in soil mass provides stronger uplift resistance, the collateral resistance that pulling force decentralized anchor pole can take full advantage of the rock anchorage body provides stronger frictional resistance, promote the pulling force effect to soldier pile, reduced the use amount of single bearing anchor.
The beneficial effects of the utility model are: can divide and fill the characteristic properties of utilizing soil layer and rock mass and provide stronger supporting power to prop, reduce the use amount of bar muscle, save engineering cost, and easy construction, effect is remarkable, is convenient to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is cross-sectional view of the present utility model.
Code description in figure: 1-soldier pile; 2-pressure dispersing type anchor pole; 3-tension and compression composite anchor-rod; 4-pulling force decentralized anchor pole; At the bottom of the 5-slope; Top, 6-slope; The 7-lithosphere; The 8-soil layer.
The specific embodiment
As shown in Figure 1, it is that (5) section is vertically installed with soldier pile (1) at the bottom of the slope, and soldier pile is provided with bolthole, is respectively equipped with pressure dispersing type anchor pole (2), pulling force decentralized anchor pole (4) and tension and compression composite anchor-rod (3) in bolthole.pressure dispersing type anchor pole (2) in the present embodiment provides uplift resistance by soil layer, be provided with free segment and the anchoring section of 4 unit, and pulling force decentralized anchor pole (4) provides frictional resistance by lithosphere, be provided with free segment and the anchoring section of 4 unit, right section of the tension and compression composite anchor-rod provides frictional resistance by lithosphere (7), be provided with the pulling force decentralized anchor pole of 2 unit, another section is to provide uplift resistance by soil layer (8), be provided with the pressure dispersing type anchor pole of 2 unit, can increase respectively or reduce according to the distribution situation in the length of anchor pole and Tu Yan place the element number of free segment and anchoring section in practice.In the utility model, the compressive resistance that the pressure dispersing type anchor pole can take full advantage of after grouting in soil mass provides stronger uplift resistance, the collateral resistance that pulling force decentralized anchor pole can take full advantage of the rock anchorage body provides stronger frictional resistance, promoted the pulling force effect to soldier pile, slope body to the Tu Yan place has stronger supporting power, reduce the use amount of single bearing anchor, thereby can save engineering cost.
