Description

Technical Field

[0001] The invention relates to the technical field of pile head processing devices, and in particular to a compression-resistant static load pile head processing device. Background Art

[0002] At present, bored cast-in-place piles refer to piles made by forming pile holes in the foundation soil by mechanical drilling, steel pipe squeezing or manual excavation at the construction site, placing steel cages in them, and pouring concrete. The advantages of bored cast-in-place piles over other piles are: 1. Bored cast-in-place piles use mechanical drilling, which has the characteristics of good hole wall stability and strong drill penetration. They can be constructed under various geotechnical conditions, which provides convenience for the subsequent pile grouting construction. At the same time, during the pile grouting process, the slurry can fully fill the pores, strengthen the pile body, and effectively improve the bearing capacity of the pile body, thereby ensuring the stability and reliability of the project quality; 2. Bored cast-in-place piles can complete multiple processes such as drilling, pouring and steel bar arrangement at one time, so the construction period is greatly shortened, and no large-scale excavation is required during its construction. Bored cast-in-place piles can also avoid pollution and damage to the surrounding environment, meeting the requirements of green construction; 3. The diameter and pile length of bored cast-in-place piles can be adjusted, suitable for various building structures, and can meet the various needs of the project.

[0003] As the scale of infrastructure construction in my country increases year by year, the number of foundation treatment methods based on reinforced concrete cast-in-place piles increases day by day, and at the same time, there are higher requirements for pile foundation static load test technology. Taking cast-in-place piles as an example, it is inevitable to deal with the pile body and pile head. The tilt and non-vertical deviation of the pile head and pile body will cause safety hazards. Utility Model Content

[0004] In order to solve one or some technical problems existing in the prior art, the purpose of the present application is to provide a compression-resistant static load pile head processing device to avoid the problem of misalignment between the pile head and the pile body.

[0005] In order to solve the above existing technical problems, one of the purposes of this application is achieved by adopting the following technical solution:

[0006] A compressive static load pile head processing device comprises a compacted soil body and a main reinforcement body located at the center of the compacted soil body, the top of the main reinforcement body is exposed to the air, a steel casing is provided on the outside of the compacted soil body, the steel casing is sleeved on the main reinforcement body, a plurality of cross-fixed positioning steel bars are provided at the bottom of the inner side of the steel casing, a plurality of the positioning steel bars are fixedly connected to the inner side wall of the steel casing, and a plurality of the positioning steel bars are also fixedly connected to the main reinforcement body, and a cast pile head is cast in the steel casing.

[0007] Furthermore, the fixing method of some of the positioning steel bars is spot welding, the fixing method of the positioning steel bars and the main reinforcement body is spot welding, and the fixing method of the positioning steel bars and the steel casing is also spot welding.

[0008] Furthermore, the end of the positioning steel bar passes through the steel casing, and a scale marking body is arranged at the position where the positioning steel bar is connected to the steel casing, and the scale marking body is arranged on the outer side wall of the steel casing.

[0009] Furthermore, four top supporting square timbers with the same cross-sectional size are arranged around the steel casing, and two adjacent top supporting square timbers are perpendicular to each other and are anchored in the compacted soil body closely against the steel casing wall.

[0010] Furthermore, the compacted soil body is also provided with oblique square timbers corresponding to the top square timbers, and the oblique square timbers are located below the top square timbers.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) The fixed positioning function is achieved by fixing the positioning steel bars with the main bars. The method of welding the positioning steel bars in the steel casing to the main bars of the pile body transforms the steel casing into a tensile and compressive rod, which greatly improves the force-bearing performance and stability of the support and helps to avoid the problem of misalignment between the pile head and the pile body. Compared with the existing technology, the problem of misalignment between the pile head and the pile body, such as inclination and non-verticality, and the technical problem of potential safety hazards is solved.

[0021] The pile head processing device for resisting compression static load comprises a compacted soil body 8, a main reinforcement body 1 is arranged at the center of the compacted soil body 8, so that the top of the main reinforcement body 1 is exposed to the air, a steel casing 3 is arranged outside the compacted soil body, so that the steel casing 3 is sleeved on the main reinforcement body 1, and a plurality of cross-fixed positioning steel bars 2 are arranged at the bottom of the inner side of the steel casing 3, the plurality of positioning steel bars 2 are fixedly connected to the inner wall of the steel casing 3, and the plurality of positioning steel bars 2 are also fixedly connected to the main reinforcement body 1, and a cast pile head 7 is cast in the steel casing 3. The fixed positioning effect is achieved by the fixed connection of the positioning steel bars 2 and the main reinforcement, and the method of welding the positioning steel bars 2 in the steel casing 3 to the main reinforcement of the pile body converts the steel casing 3 into a tension and compression rod, which greatly improves the force bearing performance and stability performance of the support, and helps to avoid the problem of displacement between the pile head and the pile body, thereby solving the technical problem of tilting, non-vertical displacement between the pile head and the pile body and the potential safety hazard compared with the prior art.

[0022] Furthermore, the fixing method of several positioning steel bars 2 is spot welding, the fixing method of positioning steel bars 2 and main reinforcement body 1 is spot welding, and the fixing method of positioning steel bars 2 and steel casing 3 is also spot welding. Several positioning steel bars 2 are welded at their intersections to form a whole, and the positioning steel bars 2, steel casing 3, and main reinforcement also form an integral structure to improve structural stability.

[0023] Furthermore, the end of the positioning steel bar 2 passes through the steel casing 3, and a scale marking body 4 is set at the position where the positioning steel bar 2 is connected to the steel casing 3, and the scale marking body 4 is set on the outer wall of the steel casing 3. It is also relatively simple to remove it later. The scale marking body 4 is welded on the surface of the steel casing 3 at the position of the positioning steel bar 2 in advance. When the concrete is poured and reaches the corresponding strength, a hole is drilled or a small cut is made at the mark on the surface of the steel casing 3 to disconnect it from the positioning steel bar 2, so as to remove the steel casing 3.

[0024] Furthermore, four top support square timbers 6 with the same cross-sectional size are arranged around the steel casing 3, and two adjacent top support square timbers 6 are perpendicular to each other and anchored in the compacted soil body 8 close to the wall of the steel casing 3. The compacted soil body 8 is also provided with diagonal support square timbers 5 corresponding to the top support square timbers 6, and the diagonal support square timbers 5 are located below the top support square timbers 6. The diagonal support and top support back-up method can reduce the displacement of the pile head during concrete pouring to a certain extent, thereby reducing the inclination of the pile head and the pile body, and the square timbers are easy to obtain and the cost is low.

[0025] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application.
