The utility model relates to a semi-pitching pile bridge abutment, and belongs to the technical field of bridge abutment supports. The pile foundations are fixedly connected with the bridge abutment body and used for supporting the bridge abutment body; the inserting pile is formed by pouring of an inserting pile formwork, one end of the inserting pile is embedded in the ground, and the other end of the inserting pile is installed on the pile foundation; the inserting piles are obliquely arranged and used for supporting the pile foundations. Due to the fact that the inserting piles are adopted to replace conical slopes, the inserting piles are simple in structure, the bridge abutment pile foundation can be supported, and due to the fact that the occupied area of the inserting piles is small, the influence on passing of vehicles is small.

Description

Technical Field

[0001] The present application relates to the technical field of abutment support, and in particular to a semi-inserted pile abutment. Background Art

[0002] Abutments are buildings located at both ends of a bridge that support the superstructure of the bridge and connect to the embankment. In addition to transferring the load of the superstructure of the bridge to the foundation, they also have the functions of resisting the fill pressure behind the abutment, stabilizing the bridgehead roadbed, and connecting the bridgehead line and the bridge line reliably and smoothly. Abutments are generally stone masonry or plain concrete structures, while light abutments are reinforced concrete structures.

[0003] At present, the soil pressure on the abutments of most structures is too large and the stability is low. In order to improve the stability, a conical slope is usually required. Since the conical slope occupies a large area, it will cause the road under the bridge to become narrower, affecting traffic. Summary of the invention

[0004] In order to improve the stability of the abutment and avoid the passage of vehicles as much as possible, the present application provides a semi-inserted pile abutment, which adopts the following technical solution:

[0005] A semi-inserted pile abutment, comprising:

[0006] Bridge abutment body;

[0007] A pile foundation, fixedly connected to the abutment body, for supporting the abutment body;

[0008] The pile is cast by a pile template, one end of which is embedded in the ground and the other end is installed on the pile foundation; the pile is inclined to support the pile foundation.

[0009] By adopting the above technical solution, since the cone slope is replaced by the inserted pile, the inserted pile structure is simple, which can not only support the pile foundation, but also has little impact on the passage of vehicles because the inserted pile occupies a small area.

[0010] Optionally, the semi-inserted pile abutment further comprises:

[0011] An adjusting sleeve is coaxially sleeved and slidably connected to the pile foundation; one end of the pile insertion template is detachably connected to the adjusting sleeve.

[0012] By adopting the above technical solution, before the piles are formed, the pile template is connected to the adjustment sleeve, and then the inclination of the pile template is adjusted. After the adjustment is completed, the pile template is poured to form the piles, thereby further improving the stability of the pile foundation support.

[0013] Optionally, the cross-section of the pile template is rectangular.

[0014] Optionally, the semi-inserted pile abutment further comprises:

[0015] A mounting plate, fixedly connected to the pile template;

[0016] The receiving plate is fixedly connected to the adjusting sleeve and is detachably connected to the mounting plate.

[0017] By adopting the above technical solution, when the inserted pile is damaged or needs to be replaced, the installation plate and the receiving plate can be separated, thereby facilitating the replacement and installation of the inserted pile.

[0018] Optionally, the semi-inserted pile abutment further comprises:

[0019] The mounting bolts are fixedly connected to the receiving plate; the mounting plate is provided with mounting holes;

[0020] The mounting nut is threadedly connected with the mounting bolt after the mounting bolt passes through the mounting hole.

[0021] Optionally, the semi-inserted pile abutment further comprises:

[0022] An auxiliary support rod has one end hinged to the adjusting sleeve and the other end hinged to the abutment body; the auxiliary support rod is a telescopic rod.

[0023] By adopting the above technical solution, the auxiliary support rod will automatically adjust its length as the adjusting sleeve moves, so as to support the abutment and pile foundation, thereby further improving the anti-tilt capability.

[0024] Optionally, the auxiliary support rod includes:

[0025] Fixed rod;

[0026] A sliding rod, slidingly connected to the fixed rod;

[0027] Two first chassis are provided, each of which is fixedly connected to one end of the fixed rod away from the sliding rod;

[0028] Two second chassis are provided, one is fixedly connected to the abutment body, and the other is fixedly connected to the adjustment sleeve; the first chassis is detachably connected to the corresponding second chassis.

[0029] By adopting the above technical solution, the auxiliary support rod is detachably connected to the abutment body and the adjusting sleeve, which facilitates the replacement and installation of the auxiliary support rod.

[0030] Optionally, the semi-inserted pile abutment further comprises:

[0031] A reinforcing rod has one end mounted on the fixing rod and the other end mounted on the pile template.

[0032] By adopting the above technical solution, the reinforcing rods support the auxiliary support rods and the pile formwork, further improving stability.

[0033] In summary, the present application has at least the following beneficial effects:

[0034] 1. The purpose of setting up piles is to replace the cone slope with piles. The pile structure is simple and can not only support the pile foundation of the abutment, but also has little impact on the traffic of vehicles because the piles occupy a small area.

[0035] 2. The purpose of setting the adjustment sleeve and the pile template is to connect the pile template with the adjustment sleeve before the pile is formed, and then adjust the inclination of the pile template. After the adjustment is completed, pour concrete on the pile template to form the pile and further improve the stability of the pile foundation support.

[0036] 3. The purpose of setting up the auxiliary support rod is that the auxiliary support rod will automatically adjust its length as the adjusting sleeve moves, so as to support the abutment body and pile foundation and further improve the anti-tilt capability.

[0037] 4. The purpose of setting up reinforcing rods is to support the auxiliary support rods and pile formwork and further improve stability. BRIEF DESCRIPTION OF THE DRAWINGS
