Description

Technical Field

[0001] This utility model relates to a foundation reinforcement pile, belonging to the field of building foundation technology in the metallurgical industry. Background Technology

[0002] Foundation refers to the soil or rock mass that supports the foundation of a building. Soil layers that form the foundation of a building are divided into rock, gravelly soil, sandy soil, silty soil, cohesive soil, and artificial fill. Among them, foundation reinforcement piles are commonly used reinforcement components in construction engineering. They play a reinforcing role within the building's strata and bear a certain load, improving the stability of the building's ground structure. During installation, foundation reinforcement piles are installed at the corresponding points using a pile driver.

[0003] In the prior art, such as Chinese patent CN218148308U, a foundation reinforcement pile is disclosed, including a reinforcement pile body. At least two outer reinforcing sleeves are fixedly installed inside the reinforcement pile body. Each outer reinforcing sleeve has two reinforcing frames facing opposite directions fixedly installed inside. At least two fixing ribs are fixedly installed between the outer wall of each pair of reinforcing frames and the inner wall of the outer reinforcing sleeve.

[0004] However, in the existing technology, most foundation reinforcement piles are made by inserting steel cages into the ground and finally pouring concrete. These reinforcement piles are usually columnar with relatively smooth surfaces and relatively small contact areas with the soil layer. The bond between the pile and the soil layer may not be strong enough, and the soil around the pile may shift laterally after a period of time, resulting in an unsatisfactory reinforcement effect. Utility Model Content

[0005] The purpose of this utility model is to provide a foundation reinforcement pile that can increase the contact area and adhesion between the reinforcement pile and the surrounding mud layer, and make the structure of the reinforcement pile more reliable, so as not to easily deform or shift laterally, thus solving the problems existing in the background technology.

[0006] The technical solution of this utility model is:

[0007] A foundation reinforcement pile includes a reinforcement pile body, a limiting cap, screws, a cavity, a movable block, a connecting rod, and an embedded block. The upper part of the reinforcement pile body is a hollow cylinder, and the lower part is a cone. The hollow part of the upper part of the reinforcement pile body is a cavity that mates with the movable block from top to bottom. The limiting cap is fixedly connected to the reinforcement pile body by screws. Each end of the reinforcement pile body is provided with an annular groove. A steel mesh is provided on the reinforcement pile body between the two grooves. An embedded block is provided in each groove, and a connecting rod that can pass into the cavity is provided on the embedded block.

[0008] The upper end of the reinforced pile body is provided with a slot, and the limiting cover is provided with an insert plate. The insert plate on the limiting cover is inserted into the slot at the upper end of the reinforced pile body.

[0009] The reinforced pile body and the limiting cover are respectively provided with screw holes in the circumferential direction to cooperate with screws.

[0010] The embedded block in the slot is a ring structure that cooperates with the body of the reinforced pile.

[0011] One side of the ring-shaped embedded block is an inclined surface.

[0012] The connecting rods on the embedded block that can pass into the cavity are arranged symmetrically.

[0013] The reinforced pile body has a slot with a through hole that mates with the connecting rod.

[0014] The beneficial effects of this utility model are:

[0015] (1) After the reinforced pile body is placed into the pre-drilled pile hole, the movable block is simply placed along the cavity. As the movable block moves downward, it will push the connecting rods on both sides outward along the through hole, thereby causing the embedded block connected to it to move to both sides and embed into the surrounding soil, thereby increasing the contact area between the reinforced pile body and the surrounding soil layer, which will increase the bonding force between the reinforced pile body and the soil layer, so that it will not easily move to the side.

[0016] (2) The steel mesh on the outside of the reinforced pile body can make the surface of the reinforced pile rough, thereby increasing the contact area between the reinforced pile body and the surrounding mud layer, and also making the structure of the reinforced pile body more reliable and less prone to deformation.

[0024] The present invention will be further described below with reference to the accompanying drawings and examples.

[0025] See attached document Figure 1-5 A foundation reinforcement pile includes a reinforcement pile body 10, a limiting cap 13, screws 18, a cavity 20, a movable block 21, a connecting rod 23, and an embedded block 24. The upper part of the reinforcement pile body 10 is a hollow cylinder, and the lower part is a cone. The hollow part of the upper part of the reinforcement pile body 10 is a cavity 20 that cooperates with the movable block 21 from top to bottom. The limiting cap 13 is fixedly connected to the reinforcement pile body 10 by screws 18. An annular groove 12 is provided at each end of the reinforcement pile body 10. A steel mesh 11 is provided on the reinforcement pile body 10 between the two grooves 12. An embedded block 24 is provided in each groove 12. A connecting rod 23 that can pass into the cavity 20 is provided on the embedded block 24.

[0026] In this embodiment, refer to the appendix Figure 1-5 The foundation reinforcement pile includes a reinforcement pile body 10, a steel mesh 11, a slot 12, a limiting cover 13, an insert plate 14, a slot 15, a second screw hole 16, a first screw hole 17, a screw 18, a cavity 20, a movable block 21, a through hole 22, a connecting rod 23, an embedded block 24, and an inclined surface 25, wherein:

[0027] The upper part of the reinforced pile body 10 is a hollow cylinder, and the lower part is a cone. The hollow upper part of the reinforced pile body 10 is a cavity 20 that fits with the movable block 21 from top to bottom. The reinforced pile body 10 has a slot 15 and screw holes 17 are evenly opened around its perimeter. An insert plate 14 is fixedly connected to the outer side of the lower middle part of the limiting cover 13. The insert plate 14 is snapped into the slot 15. Screw holes 16 are evenly opened around the outer side of the upper end of the limiting cover 13. Screws 18 are threadedly connected between screw holes 17 and screw holes 16. A steel mesh 11 is fixedly connected to the middle of the outer surface of the reinforced pile body 10.

[0028] The reinforcing pile body 10 has slots 12 on both the upper and lower sides of its outer surface. A movable block 21 is slidably engaged in the middle of the cavity 20. Through holes 22 are opened on both the upper and lower sides of the middle of the cavity 20. A connecting rod 23 is slidably engaged in the surface of the through hole 22. The length of the connecting rod 23 is greater than the length of the through hole 22. An embedded block 24 is fixedly connected to one end of the connecting rod 23. One side of the embedded block 24 is an inclined surface 25. The embedded block 24 is engaged with the slot 12.

[0029] By opening a slot 12 on the surface of the reinforced pile body 10, and placing an embedded block 24 in the slot 12, one side of the embedded block 24 is inclined so that it can be embedded into the surrounding soil when in use. After the reinforced pile body 10 is placed into the pre-opened pile hole, the movable block 21 is simply inserted along the cavity 20. When inserted, as the movable block 21 moves downward, it will push the connecting rods 23 on both sides outward along the through hole 22, thereby driving the embedded block 24 connected to it to move to both sides and embed into the surrounding soil, thereby increasing the contact area between the reinforced pile body 10 and the surrounding soil layer, and playing the role of increasing the adhesion between the reinforced pile body 10 and the soil layer.

[0030] After the movable block 21 is driven into the cavity 20, the operator only needs to lock the limiting cover 13 into the slot 15 provided above the reinforced pile body 10, align several screw holes 17 and 16, and then drive in the screws 18 used to fix the limiting cover 13 and the reinforced pile body 10 to complete the installation. The steel mesh 11 can roughen the surface of the reinforced pile body 10, thereby increasing the contact area between the reinforced pile and the surrounding mud layer, and also making the structure of the reinforced pile more reliable and less prone to deformation.
