Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy project foundation pile. Background Art

[0002] A water conservancy engineering foundation pile is a foundation pile used for water conservancy engineering construction. When the upper soil layer is weak and cannot meet the bearing capacity and deformation requirements of the water conservancy engineering construction, and there is a good soil layer at the bottom, the pile is used to penetrate the weak soil layer to transfer the load of the water conservancy engineering construction to the lower soil layer with stronger bearing capacity, so as to improve the rigidity of the foundation. A water conservancy engineering construction foundation pile described in publication number CN217998138U is used to stably connect the pile body and the foundation through friction convex points and triangular wedge blocks to increase friction performance. The arc-shaped connecting plate will drive the reinforcing side rod to push out of the reinforcing hole, so that the reinforcing side rod enters the foundation soil, realizes the support and fixation of the pile body around the body, and avoids loosening and displacement. However, the prior art still has the following defects:

[0003] 1. In the prior art, fixed slide rails are provided on both sides of the top of the fixed plate, and fixed sliders are slidably connected to the fixed slide rails. An arc-shaped connecting plate is welded and fixed to one side of the top of the fixed slider, and a reinforcing side rod is welded and fixed to one side of the top of the arc-shaped connecting plate. The foundation pile is fixed by pushing the reinforcing side rod out of the pile body, but the running stroke of the side rod is limited, the fixing effect is general, and the foundation pile has the risk of shaking.

[0004] 2. In the prior art, a number of triangular wedge-shaped blocks are evenly welded and fixed on the top side of the pile tip on the outside of the pile body, and uneven friction bumps are evenly arranged on the outside of the pile tip to enhance the friction when the pile is inserted. However, when piling, the pile is not fixed properly and cannot be guaranteed to be perpendicular to the ground, so the pile may tilt. Utility Model Content

A water conservancy project foundation pile comprises a pile body 1, and an annular support plate 2 is slidably connected to the outer side wall of the pile body 1, which can provide support force for the pile body 1 during movement. In order to prevent the pile body 1 from tilting during insertion into the soil layer, a fixing mechanism 3 used in conjunction with the support plate 2 is arranged on the upper side of the outer wall of the pile body 1. The fixing mechanism 3 comprises a fixing frame 31, which is movably connected to the outer side wall of the pile body 1, and four fixing rods 32 are fixedly connected to the bottom end of the fixing frame 31. The bottom end of the fixing rod 32 is conical, which is convenient for fixing it in the soil layer by hammering, and fixing the fixing frame 31 is fixed. Four limiting strips 34 are provided on the outer side wall of the pile body 1, and four limiting grooves 33 used in conjunction with the limiting strips 34 are provided on the inner walls of the fixing frame 31 and the support plate 2, which are used to limit the movement of the fixing frame 31 and the support plate 2 and improve the stability of the device.

[0023] A closing cover 4 is threadedly connected to the outer upper end of the pile body 1, so that the user can insert the pile body 1 into the deep soil layer by hammering the closing cover 4. The closing cover 4 is made of high-strength stainless steel to improve the durability of the device. At the same time, anti-slip grooves are provided on the upper side of the outer wall of the closing cover 4 to increase friction, so that the user can easily detach the pile body 1 by rotating it. In order to ensure that the pile body 1 can remain stable after being inserted into the soil layer and will not shake, which will affect subsequent projects, two auxiliary mechanisms 5 distributed up and down are fixedly connected inside the pile body 1.

Eight limit plates 52 are provided at the upper end of the chassis 51. The limit plates 52 are grouped in pairs and evenly distributed on the upper side of the chassis 51. The opposite sides of two limit plates 52 in a group are slidably connected to the insertion rod 85 to prevent the insertion rod 85 from shifting during movement and affecting the fixation of the pile body 1. Eight through holes 53 are provided on the outer side wall of the pile body 1. There are four through holes 53 distributed on the upper and lower outer walls of the pile body 1, which are used in conjunction with the insertion rod 85 to facilitate its extension from the inside of the pile body 1.

[0025] In order to be able to dismantle the fixing frame 31 and the fixing rod 32 after the pile body 1 is fixed, so as to reduce the surface area occupied by the device, four locking mechanisms 6 are movably connected to the support plate 2 and penetrated therethrough, and the locking mechanism 6 includes a sleeve 61, which penetrates the support plate 2 and the fixing frame 31, and the side wall of the sleeve 61 is movably connected to the two, and a shaft rod 62 is slidably connected inside the sleeve 61, and a round cover is fixedly connected to the top end of the shaft rod 62 to facilitate the control of the movement of the shaft rod 62, and fixing balls 63 penetrating its side wall are movably connected to the outer ends of the sleeve 61, and the fixing balls 63 can be stuck in the bottom end of the support plate 2 when a part of the fixing balls 63 are extended out of the sleeve 61, thereby limiting the movement of the sleeve 61, and a groove 64 is provided at the lower end of the shaft rod 62, and the groove 64 can be used to temporarily store the fixing balls 63, so that they are retracted into the sleeve 61, so that the sleeve 61 can be inserted into or pulled out of the support plate 2 and the fixing frame 31.

[0026] In order to facilitate the control of the movement of the shaft 62, four reciprocating mechanisms 7 are movably connected above the support plate 2.
