Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an anti-slide pile for slope management and a construction method thereof. Background Art

[0002] Anti-slide piles are one of the important landslide prevention technologies with their advantages of strong anti-slide ability, flexible pile position, and convenient construction. They are widely used to control slopes with large landslide thrust. The anti-slide bearing capacity of anti-slide piles is generally positively correlated with the cross-section. Therefore, when the on-site construction conditions permit and combined with the size of the remaining landslide thrust, the larger the cross-section of the anti-slide piles, the better the anti-slide effect and the lower the project cost. Most of the existing tunnel entrance anti-slide piles have the following problems when used:

[0003] 1. Although a single anti-slide pile can, to a certain extent, support the sliding force of the sliding body when in use, a single anti-slide pile structure does not have a strong effect of stabilizing the slope and is not suitable for mountain tunnel projects. It cannot achieve a strong reinforcement effect on the road surface and embankment of the tunnel entrance section. During the application process, its strength is not high and there are certain limitations in its use.

[0004] 2. Most anti-slip piles need to be positioned in advance during the construction process, and then positioned again after the anti-slip piles are fixed. This operation method is time-consuming and labor-intensive, and cannot achieve the purpose of accurate and rapid positioning of the anti-slip piles by construction personnel, and is relatively troublesome during operation. Summary of the invention

[0005] In order to overcome the defects of the prior art, an anti-slide pile for slope management and a construction method thereof are provided to solve the problem that the construction and positioning operation of the existing anti-slide piles are complicated.

[0006] In order to achieve the above object, an anti-slide pile for slope management is provided, comprising:

[0007] A plurality of composite pile bodies, the composite pile bodies comprising a vertically arranged pile pipe and post-cast concrete, a positioning collar installed inside the pile pipe, a positioning rod for positioning the pile core of the composite pile body detachably inserted in the positioning collar, the positioning collar coaxially arranged with the pile pipe, a plurality of stirrup frames arranged in a vertical direction are sleeved on the outside of the pile pipe, the plurality of stirrup frames are connected with a plurality of connecting bars, the plurality of connecting bars are arranged at intervals along the circumferential direction of the stirrup frames, the stirrup frames are connected to the pile pipe through a connecting piece, the post-cast concrete is coated on the plurality of stirrup frames and the pile pipe, and the post-cast concrete is poured into the pile pipe;

[0008] A connecting plate, wherein opposite ends of the connecting plate are respectively connected to a plurality of stirrup frames of two adjacent composite bodies.

[0009] Furthermore, the stirrup frame is rectangular, and has a first side and a second side opposite to each other in the length direction of the stirrup frame, and opposite sides of the pile pipe are respectively connected to the first side and the second side of the stirrup frame through the connecting piece.

[0010] Furthermore, the stirrup frame has a third side and a fourth side opposite to each other in the width direction of the stirrup frame, and the connecting bars are arranged on the third side and the fourth side of the stirrup frame.

[0011] Furthermore, the positioning collar is connected to the pile pipe via a plurality of spokes, and the spokes are arranged along the radial direction of the pile pipe.

[0012] Furthermore, the connecting plate includes a plurality of corrugated steel plates spliced ​​together.

[0013] Furthermore, the number of the positioning collars is at least two, and the two positioning collars are arranged along the axial direction of the pile pipe.

[0014] The present invention provides a construction method of anti-slide piles for slope management, comprising the following steps:

The plurality of stirrup frames 15 are connected with a plurality of connecting bars 16. The plurality of connecting bars 16 are arranged at intervals along the circumferential direction of the stirrup frames 15. The stirrup frames 15 are connected to the pile pipe 11 through a connecting piece 17. The post-cast concrete 12 is coated on the plurality of stirrup frames 15 and the pile pipe 11. The post-cast concrete 12 is poured into the pile pipe 11.

[0035] As a preferred embodiment, the stirrup frame 15 is rectangular and has a first side and a second side opposite to each other in the length direction of the stirrup frame 15. The opposite sides of the pile pipe 11 are connected to the first side and the second side of the stirrup frame 15 through connectors 17, respectively.

[0036] In this embodiment, the stirrup frame 15 has a third side and a fourth side opposite to each other in the width direction of the stirrup frame 15. The connecting bars 16 are provided on the third side and the fourth side of the stirrup frame 15.

[0037] See also Figure 3 As shown, the positioning collar 13 is connected to the pile pipe 11 through a plurality of spokes 18. The spokes 18 are arranged along the radial direction of the pile pipe 11.

[0038] The number of the positioning collars 13 is at least two. The two positioning collars 13 are arranged along the axial direction of the pile pipe 11 .

[0039] The opposite ends of the connecting plate 2 are respectively connected to a plurality of stirrup frames 15 of two adjacent composite bodies.

[0040] In this embodiment, the connecting plate 2 includes a plurality of corrugated steel plates spliced ​​together.

[0041] The present invention provides a construction method of anti-slide piles for slope management, comprising the following steps:

[0042] S1. Determine the pile center positions of a plurality of composite pile bodies 1.

[0043] S2, inserting the positioning rod 14 of the composite pile body 1 at the pile center position.

[0044] S3, sleeve the positioning ring 13 in the pile pipe 11 of the composite pile body 1 onto the positioning rod 14.

[0045] S4, a plurality of stirrup frames 15 are sleeved on the outside of the pile pipe 11 , and a plurality of connecting bars 16 are connected to the plurality of stirrup frames 15 .

[0046] S5, connecting the connecting piece 17 to the stirrup frame 15 and the pile pipe 11.

[0048] S7 , pouring the post-cast concrete 12 , so that the post-cast concrete 12 covers the plurality of stirrup frames 15 and the pile pipe 11 , and the post-cast concrete 12 is poured into the pile pipe 11 to form the composite pile body 1 .

[0049] The outside of the pile pipe of the anti-slide pile for slope management of the present invention is connected to the stirrup frame by welding. Since the stirrup frame is arranged outside the pile pipe, the strength between the pile pipe and the ground can be improved. The stirrup frames are connected to the connecting plates by welding.

[0050] The connecting plate is formed by multiple corrugated steel plates spliced ​​horizontally, which can improve the connection strength of the connecting plate. Multiple corrugated steel plates are fixed with fastening bolts. Since fastening bolts are used to connect multiple corrugated steel plates, it is convenient for construction workers to operate.

[0051] The inner part of the stirrup frame is fixed with connecting bars. The connecting bars are evenly distributed. By adding connecting bars inside the stirrup frame, the strength of the stirrup frame can be improved, and the functionality is strong.

[0052] The inside of the pile pipe is connected to the spokes by welding. The middle of the spokes is connected to the positioning collar by welding. The positioning collar is inserted into the positioning rod movably. By providing a corresponding positioning rod structure inside the pile pipe, the accuracy of construction is improved, and time and labor are saved during operation.

[0053] The spokes are evenly distributed, and the bottom of the positioning rod is set as a triangular structure. By setting the bottom of the positioning rod as a triangular structure, it can be easily inserted into the ground, and the operation is more convenient.

[0054] The stirrup frame and the pile pipe are connected by welding. A welding opening is provided on the surface of the connecting piece. By connecting the stirrup frame and the pile pipe with the connecting piece, stability can be improved during subsequent concrete pouring.

[0055] When applying the anti-slip pile for slope management of the present invention, it is necessary to first determine the specific location of the construction, and then the positioning rod is added inside the pile pipe to achieve the purpose of early positioning. During construction, it is only necessary to first measure the position of the corresponding pile center, then insert the positioning rod into the ground in advance, and then sleeve the pile pipe on the outside of the positioning rod, and after adjusting the position, fix the pile pipe on the ground to complete the positioning of the pile pipe. There is no need to repeatedly measure the position of the pile pipe, which improves the accuracy during construction.

[0056] After the initial fixation between the pile pipe and the ground is completed, the positioning rod can be pulled out, and then the subsequent concrete pouring work can be carried out. Then the stirrup frame is sleeved on the outside of the pile pipe, and a connector is used to connect the stirrup frame and the pile pipe with each other, so as to connect and fix the stirrup frame and the pile pipe together.

[0057] Then the connecting plate is constructed. Since multiple corrugated steel plates are spliced ​​horizontally, fastening bolts are needed to connect the corrugated steel plates. Then the spliced ​​connecting plate is welded to the stirrup frame outside the pile pipe.

[0058] Finally, concrete is poured to realize the construction of the anti-slip piles for slope management of the present invention, thereby forming a continuous reinforcement structure, improving the strength of the anti-slip piles for slope management of the present invention when used in mountain tunnel projects, and achieving a better effect of stabilizing the slope. The overall structure is simple and has strong practicality.

[0059] The anti-slip pile for slope management of the present invention improves the strength of the anti-slip pile when used in a slope project, can achieve a better effect of stabilizing the slope, has a simple overall structure, and is highly practical.

[0060] The anti-slip piles for slope management of the present invention are very convenient to operate, save time and effort, and have high accuracy.

[0061] The anti-slide pile for slope management of the present invention combines a connecting plate and a composite pile body, thereby improving the strength of the anti-slide pile when used in a slope project, and can achieve a better effect of stabilizing the slope. The overall structure is simple and the practicability is strong.

[0062] The anti-slip pile for slope management of the present invention can position the pile center of the composite pile body in advance by adding a positioning rod inside the composite pile body. During construction, it is only necessary to measure the corresponding position first, then insert the positioning rod into the ground, and then sleeve the positioning collar of the pile pipe on the outside of the positioning rod. After adjusting the position, the positioning work of the composite pile body can be completed, and there is no need to repeatedly measure the position of the composite pile body, which improves the accuracy during construction. After the initial fixation between the composite pile body and the ground is completed, the positioning rod can be pulled out, and then the subsequent concrete pouring work can be carried out. The operation is very convenient, time-saving and labor-saving, and the accuracy is relatively high.
