Detailed Description
The present application is described in further detail below with reference to figures 1-5.
The embodiment of the application discloses anchor rope shutoff pier nose connection structure.
As shown in fig. 1 and 2, an anchor cable plugging pier head connecting structure comprises an anchor cable and an anchor pier 3, wherein the anchor cable comprises an anchor plate 1, an anchor device 2 and steel strands 5.
The anchor plate 1 is a square, in this case a 300mm 20mm steel plate. One end of the steel plate is connected to a slope with a corresponding anchor hole in construction in an abutting mode, and an asphalt coating used for corrosion prevention is arranged on the anchor plate 1.
The anchor 2 is cylindrical, and the anchor 2 is arranged at the center of one end of the anchor plate 1, which is far away from the slope bearing surface.
The anchor plate 1 is used for being mutually abutted with the bearing surface to bear the prestress of the steel strand 5, and the anchorage device 2 is used for fixedly mounting the steel strand 5.
As shown in fig. 3 and 4, the anchorage device 2 is provided with a plurality of first mounting holes for the steel strands 5 to penetrate through, the anchor plate 1 is provided with a plurality of second mounting holes for the steel strands 5 to penetrate through, and the first mounting holes and the second mounting holes are arranged correspondingly. The number of the first mounting holes is 9, one of the first mounting holes is located at the center of the anchor 2, the other 8 first mounting holes are uniformly arranged around the periphery along the center line of the anchor 2, and the distance and the angle between every two adjacent first mounting holes are the same. Therefore, after the steel strand 5 is installed, the stress is uniform, and the steel strand 5 installed at a hole site is prevented from being broken due to more stress caused by the deviation of the hole site at a certain position. The opening position of the second mounting hole corresponds to the opening position of the first mounting hole.
As shown in fig. 1 and 2, the anchor block 3 includes a body 31 and a plurality of anchoring hooks 32, the body 31 is formed by pouring concrete and has a trapezoidal shape, the top end and the bottom end of the body 31 are both in the positive direction, and the area of the top end is smaller than that of the bottom end. The bottom end of the body 31 covers the entire anchor plate 1 and has an area larger than that of the anchor plate 1. The anchoring hook rib 32 is located in the body 31 and used for supporting the body 31, and the end part of the anchoring hook rib 32 is fixedly connected to the anchor plate 1.
The anchoring bent rib 32 is a round bar of 6 or 8 in this application.
The body 31 uses fine stone concrete with grade not lower than C30.
By the method, after the steel strand 5 is installed on the anchor plate 1 and the anchorage device 2, the anchoring bent hook rib 32 is welded on the anchor plate 1, and concrete is used for grouting to form the corresponding anchor pier 3. Make anchor pier 3 can be to ground tackle 2, anchor slab 1 and naked hourglass carry out the shutoff with steel strand wires 5 outside the ground tackle fixedly, at ground tackle 2, anchor slab 1 has on the face of accepting through anchor pier 3 and slope the junction forms a whole, simultaneously because in the construction, need be at ground tackle 2, anchor slab 1 and naked hourglass scribble anticorrosive material such as pitch and butter on the steel strand wires 5 outside the ground tackle, anchor pier 3 and anchor slab 1 like this, there is the interlayer between ground tackle 2, lead to anchor pier 3 to drop very easily, the event collude muscle 32 through buckling the anchor and sets up at this internally, make the body have the drawknot point, body 31 and ground tackle 2 in the anchor pier 3 have been strengthened, anchor slab 1 and the connection of the steel strand wires 5 of naked hourglass outside the ground tackle, make the anchor pier 3 of concrete can not drop or become flexible.
As shown in fig. 1 and 4, the anchoring curved-hooking rib 32 includes a first rib portion 321, a second rib portion 322 and a third rib portion 323, the first rib portion 321 is fixed on the anchor plate 1, and the first rib portion 321 and the anchor plate 1 are parallel to each other. Second muscle 322 and first muscle 321 are the acute angle setting between, and second muscle 322 is parallel with the adjacent side of body 31, and third muscle 323 and second muscle 322 are the right angle setting between. Through the setting of the inner inclination angle, the rudiment framework of the trapezoid body is formed when the body 31 is poured, and the best supporting effect of the anchor pier 3 with the shape can be obtained after the analysis of the supporting stress.
The specific angle and length can be changed according to the specification of the anchor pier and the design size requirement of plugging.
As shown in fig. 1 and 2, in one embodiment, four anchoring hooks 32 are provided, and four anchoring hooks 32 are wound around the body 31 at equal intervals. Furthermore, because the anchor plate 1 is square, the four anchoring bent-hooking ribs 32 are respectively arranged at the four corners of the anchor plate 1, so that the strength distribution is more uniform.
As shown in fig. 4 and 5, when the steel strand 5 is installed, in order to ensure the stability of the steel strand 5, a clip installation part 4 is further arranged on the anchorage device 2, the thickness of one end, away from the anchor plate 1, of the clip installation part 4 is greater than the thickness of one end, close to the anchor plate 1, of the clip installation part 4, the clip installation part 4 is in interference fit with the first installation hole, after the steel strand 5 passes through the first installation hole and the second installation hole respectively, the end, with smaller thickness, of the clip installation part 4 is inserted into a gap between the first installation hole and the steel strand 5, the thickness of the other end is larger, when the steel strand 5 needs to move inwards due to stress, due to the interference fit between the clip installation part 4 and the first installation hole as well as the steel strand 5, the tension is tighter, a certain creep occurs under the action of prestress, the anticorrosion effect is ensured, and a certain protective layer space is reserved.
Further, in order to avoid the rib falling condition after concrete pouring, at least 25mm of gap is left between the body 31 and the anchoring hook rib 32 to be used as a protective layer.
The implementation principle is as follows:
after the steel strand 5 is installed on the anchor plate 1 and the anchorage device 2, the anchoring bent hook rib 32 is welded on the anchor plate 1, and concrete is used for grouting to form the corresponding anchor pier 3. Make anchor pier 3 can be to ground tackle 2, anchor slab 1 and the steel strand wires 5 of naked hourglass outside ground tackle block up fixedly, at ground tackle 2, anchor slab 1 has had the junction to form a whole on the face of accepting through anchor pier 3 and slope, simultaneously because in the construction, need be at ground tackle 2, anchor slab 1 and naked hourglass scribble anticorrosive material such as pitch and butter on the steel strand wires 5 outside ground tackle, anchor pier 3 and anchor slab 1 like this, there is the interlayer between ground tackle 2, lead to anchor pier 3 to drop very easily, the event colludes muscle 32 through with the anchor bend and sets up originally internally, make the body have the bonding point, body 31 and ground tackle 2 in the anchor pier 3 have been strengthened, anchor slab 1 and the naked connection of leaking the steel strand wires 5 outside ground tackle, make the anchor pier 3 of concrete can not drop or become flexible.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
