Abstract
The utility model discloses a structure for reinforcing and fixing a slope surface of a prestress anchoring frame beam, comprising a frame beam (1), wherein the frame beam (1) is connected with an anchor rope (4). The structure is characterized in that grouting pipes (2) are arranged under cross beams and vertical beams of the frame beam (1), exposed parts of the grouting pipes (2) are inserted in the frame beam (1) and fixedly connected with reinforcement bars of the frame beam (1), and the frame beam (1) and the grouting pipes (2) are fixed by casting concrete. The structure has the advantages of small volume, shortened period, saved engineering cost, and the like, and is applicable to cohesive soil, sandy soil, sandy gravel (pebblestone) layers, residual soil, slops with wholly-weathered rocks and highly weathered rocks, easily and moderately weathered soft rocks and extremely soft rocks.
Description
Technical field
The utility model relates to domatic reinforcing of a kind of prestress anchoraging Vierendeel girder 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.Vierendeel girder also claims lattice or panel grider, is a kind of of outer anchor structure thing, adopts reinforced concrete structure, is made of crossbeam and vertical beam, is intersecting parallels, at crossbeam and vertical beam intersection point place prestress anchorage cable (as shown in Figure 2) is set.
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, Vierendeel girder on domatic can produce sinking, cause loss of prestress, cause anchoring engineering to lose efficacy.Be the requirement of satisfying the geotechnical body bearing capacity by the crossbeam that increases and vertical beam width at present.Yet the increase of sectional dimension can cause construction costs to increase defectives such as claim for eot.
Vierendeel girder fixing on domatic mainly realized by the prestress anchorage cable of Vierendeel girder node.When domatic steeper, when not having enough time to carry out anchorage cable stretching, Vierendeel girder along domatic downslide, causes Vierendeel girder to destroy under action of gravity.Prevent that at present Vierendeel girder from being the length that increases vertical beam along the measure of domatic downslide, be supported on the plain stage of slope at the bottom of making vertical beam.Defectives such as the engineering quantity that this has also increased Vierendeel girder causes the cost height, and is long in time limit.A little less than the loose geotechnical body side slope scouring-resistance ability, washing away for a long time of rainwater can be emptied the framework ground, causes Vierendeel girder to destroy simultaneously.
Summary of the invention
The purpose of this utility model is: domatic reinforcing of a kind of prestress anchoraging Vierendeel girder and fixed structure are provided, satisfying under the prerequisite of identical anchoring effect, adopt the Vierendeel girder 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 Vierendeel girder, Vierendeel girder connects anchor cable, under the crossbeam of Vierendeel girder and vertical beam grouting tube is set, and the exposed parts of floral tube inserts in the Vierendeel girder, fixedly connected with the reinforcing bar of Vierendeel girder, Vierendeel girder and floral tube are fixed by concreting.
Above-mentioned domatic reinforcing of prestress anchoraging Vierendeel girder 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 Vierendeel girder and fixed structure, floral tube are arranged under the crossbeam and vertical beam of Vierendeel girder, and the spacing of floral tube is 50cm～80cm on the length direction of crossbeam and vertical beam; The spacing of floral tube is 20cm～30cm on width.
The present invention inserts grouting tube in the ground below the prestress anchoraging Vierendeel girder, by slip casing by pressure, improved the character of Vierendeel girder 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 Vierendeel girder designing and calculating, design same prestressing force, because of bearing capacity of foundation soil improves, can reduce prestress anchoraging Vierendeel girder sectional dimension, thereby reduce the consumption of prestress anchoraging Vierendeel girder steel concrete, both saved the duration, also saved investment.The floral tube exposed parts effectively is connected with the prestress anchoraging Vierendeel girder, floral tube and prestress anchoraging Vierendeel girder 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 Vierendeel girder effectively fixing on side slope surface, thereby reduce the length and the width of prestress anchoraging Vierendeel girder, reduce the consumption of steel concrete, reduce investment outlay.Compare with prior art, it is little that the present invention has an anchoring Vierendeel girder 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 Vierendeel girder 1 domatic 3, Vierendeel girder 1 connects prestress anchorage cable 4, during making, earlier under the crossbeam of Vierendeel girder 1 and vertical beam, grouting tube 2 is set, the exposed parts of floral tube 2 is inserted in the Vierendeel girder 1, fixedly connected, Vierendeel girder 1 and floral tube 2 are fixed together by concreting with the reinforcing bar of Vierendeel girder 1, concrete reaches after the intensity and then to Vierendeel girder 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 Vierendeel girder 1, floral tube 2 is arranged under the crossbeam and vertical beam of Vierendeel girder 1, and the spacing of floral tube 2 is 50cm～80cm on the length direction of horizontal 25 beams and vertical beam; The spacing of floral tube 2 is 20cm～30cm on width, and effect is better.
