Abstract
The utility model discloses a prestressed anchorage anchor pier slope reinforcing and fixing structure, which comprises an anchor pier (1) connected with an anchor cable (4), and is characterized in that: a grouting perforated pipe (2) is arranged below the anchor pier (1), and the exposed part of the perforated pipe (2) is inserted in the anchor pier (1) and is fixedly connected with reinforcing steel bars of the anchor pier (1); and the anchor pier (1) and the perforated pipe (2) are fixed by concrete pouring. The grouting perforated pipe is inserted in the foundation below the prestressed anchorage anchor pier, the properties of rock-soil mass of the anchor pier foundation can be improved by pressure grouting, and the perforated pipe is inserted in the rock-soil mass, thereby greatly improving the bearing capacity of the foundation rock-soil mass. In the process of calculation of the prestressed anchorage anchor pier design, when the same prestressing force is designed, the size of the cross section of the prestressed anchorage anchor pier can be improved because the bearing capacity of the foundation improves, thereby reducing the consumption of prestressed anchorage anchor pier reinforced concrete, and saving construction time limit and investment.
Description
Technical field
The utility model relates to domatic reinforcing of a kind of prestress anchoraging anchor pier and fixed structure, belongs to domatic fixing, reinforcing technique field.
Background technology
Prestress anchoraging is numerous industries such as water conservancy, railway, mine, highway and city-building be used for coming down effective means of regulation, slope reinforcement, deep foundation pit support, structure overturning or slip resistance analysis, underground engineering wall rock reinforcing, abutment reinforcing etc.According to the difference of primary structure member, can be divided into anchor pole and anchor cable, in the prestress anchoraging engineering, main application is anchor cable at present.
Prestress anchorage cable mainly is made of anchoring section, free section and fastener head three parts, and fastener head is made up of outer anchor structure thing, billet and ground tackle.Anchor pier is a kind of of outer anchor structure thing, adopts reinforced concrete structure, and prestress anchorage cable (as shown in Figure 2) is set in the middle of anchor pier.
When on loose geotechnical body side slope, carrying out the large-tonnage prestressed anchor reinforcement, domatic geotechnical body bearing capacity deficiency, apply in the prestressing force process or after applying prestressing force, can cause that being reinforced geotechnical body produces bigger creep and plastic strain, anchor pier on domatic can produce sinking, cause loss of prestress, cause anchoring engineering to lose efficacy; A little less than the loose geotechnical body side slope scouring-resistance ability, under the long-term souring of rainwater, can cause anchor pier to come to nothing, cause anchoring engineering to lose efficacy.Be the requirement of satisfying the geotechnical body bearing capacity by the floor space of the anchor pier that increases at present, by advancing the domatic anchor pier that prevents and come to nothing anchor pier being embedding.Yet the increase of sectional dimension can cause construction costs to increase, and long-term slope wash meeting progressively makes the anchor pier bottom surface expose, and comes to nothing, and embedding anchor pier can not guarantee the long-time stability of anchoring engineering.
Summary of the invention
The purpose of this utility model is: domatic reinforcing of a kind of prestress anchoraging anchor pier and fixed structure are provided, satisfying under the prerequisite of identical anchoring effect, adopt the anchor pier of reduced size also can realize effectively fixing, satisfy the requirement of side slope surface bearing capacity, thereby save engineering cost.
The utility model is to constitute like this: comprise anchor pier, anchor pier connects anchor cable, under anchor pier grouting tube is set, and the exposed parts of floral tube inserts in the anchor pier, fixedlys connected with the reinforcing bar of anchor pier, and anchor pier and floral tube are fixed by concreting.
Above-mentioned domatic reinforcing of prestress anchoraging anchor pier and fixed structure, described floral tube front end is taper, is provided with the spillage hole on floral tube, the not boring that leaves at least 20 centimetres at the floral tube afterbody ends the slurry section, injects cement mortar or cement paste in floral tube.
Above-mentioned domatic reinforcing of prestress anchoraging anchor pier and fixed structure, floral tube is arranged under the anchor pier, and the spacing of floral tube is 50cm～80cm in the longitudinal direction; The spacing of floral tube is 20cm～30cm on width.
The present invention inserts grouting tube in the ground below the prestress anchoraging anchor pier, by slip casing by pressure, improved the character of anchor pier ground geotechnical body, and floral tube insertion geotechnical body, plays the pile foundation effect, thereby has improved the bearing capacity of ground geotechnical body greatly.When carrying out prestress anchoraging anchor pier designing and calculating, design same prestressing force, because of bearing capacity of foundation soil improves, can reduce prestress anchoraging anchor pier sectional dimension, thereby reduce the consumption of prestress anchoraging anchor pier steel concrete, both saved the duration, also saved investment.The floral tube exposed parts effectively is connected with the prestress anchoraging anchor pier, floral tube and prestress anchoraging anchor pier are fused form the outer anchor structure thing of prestress anchoraging jointly, because the most of people's geotechnical body of inserting of floral tube, can realize prestress anchoraging anchor pier effectively fixing on side slope surface, thereby reduce the size of prestress anchoraging anchor pier, reduce the consumption of steel concrete, reduce investment outlay.Compare with prior art, it is little that the present invention has an anchor pier volume, in the shortening cycle, saves advantages such as engineering cost.Be applicable to cohesive soil, sand, sand ovum (gravel) stone layer, residual clinosol, completely decomposed rock and strong-weathered rock side slope, the middle weathering soft rock of easy-weathering, dead-soft rock also can adopt.

The specific embodiment
Embodiment of the present utility model: make anchor pier 1 domatic 3, anchor pier 1 connects prestress anchorage cable 4, during making, earlier 1 time grouting tube 2 is set at anchor pier, the exposed parts of floral tube 2 is inserted in the anchor pier 1, fixedly connected, anchor pier 1 and floral tube 2 are fixed together by concreting with the reinforcing bar of anchor pier 1, concrete reaches after the intensity and then to anchor pier 1 and carries out the stretch-draw and the anchoring of anchor cable 4, and anchoring process gets final product according to existing construction technology.
According to the shape size of domatic 3 angles of inclination and anchor pier 1, floral tube 2 be arranged on anchor pier 1 around, the spacing of floral tube 2 is 50cm～80cm in the longitudinal direction; The spacing of floral tube 2 is 20cm～30cm on width, and effect is better.
