DETAILED DESCRIPTION
[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0019] like Figure 1 As shown, a reinforcement device for a soft soil foundation of a railway includes a base 1, a top seat 2, a connecting seat 3 and a reinforcement mechanism 4.
[0020] like Figure 1 , Figure 2 As shown, the base 1 is opened at the upper end and is arranged in a reinforcement hole on the ground, the top seat 2 is opened at the lower end and is arranged above the base 1, the connecting seat 3 is arranged in a pipe-like shape between the base 1 and the top seat 2, and the reinforcement mechanism 4 is arranged between the base 1 and the connecting seat 3 and between the top seat 2 and the connecting seat 3.
[0021] like Figure 1 , Figure 2As shown, a plurality of overflow holes 5 are provided on the base 1, the top seat 2 and the connecting seat 3, so that when pouring concrete, the concrete can enter the reinforcement device, and at the same time, the concrete slurry can penetrate into the surrounding soil to reinforce the soil around the reinforcement device, thereby further improving the stability of the reinforcement device.
[0022] like Figure 1 , Figure 2 As shown, the base 1, the top seat 2 and the connecting seat 3 are all provided with reinforcing frames 6 to improve the structural strength and pressure bearing capacity of the entire reinforcement device.
[0023] like Figure 1 , Figure 4 As shown, a steel cage 7 is vertically arranged above the top seat 2, a dovetail block 71 is arranged on the lower end surface of the steel cage 7, and a groove 72 for the dovetail block 71 to be embedded in and a dovetail groove 73 connecting the groove 72 and for the dovetail block 71 to be embedded in are arranged on the top seat 2.
[0024] Therefore, by providing a clamping fixed steel cage 7, the steel cage 7 is connected to the top seat 2, so that after pouring concrete in the later stage, the cast-in-place pile and the reinforcement device are stably connected and fixed together, thereby improving the compressive resistance and stability.
[0025] like Figure 1 , Figure 2 As shown, the reinforcement mechanism 4 includes an upper reinforcement plate 41, a lower reinforcement plate 42 and a locking member 43. The ends of the upper reinforcement plate 41 and the lower reinforcement plate 42 that are close to each other are rotatably connected and are used to flip outward after being stressed, and the ends of the upper reinforcement plate 41 and the lower reinforcement plate 42 that are away from each other are rotatably connected to the base 1 and the connecting seat 3 or the top seat 2 and the connecting seat 3 respectively.
[0026] like Figure 1 , Figure 2 As shown, the locking member 43 is used to fix the upper reinforcing plate 41 and the lower reinforcing plate 42 , and the locking member 43 includes a locking rod 44 , a locking tube 45 and a locking ring 46 .
[0027] like Figure 1 , Figure 2 As shown, the locking rod 44 is vertically arranged on the top seat 2, and the locking tube 45 is vertically arranged on the base 1 and is inserted into the locking rod 44. The locking ring 46 is arranged obliquely upward on the outer wall of the lower end of the locking rod 44, and the inner wall of the locking tube 45 is provided with a plurality of locking grooves 47 for the locking ring 46 to be inserted.
[0028] When it is necessary to reinforce the soft soil foundation, the reinforcement mechanism 4 is placed into the reinforcement hole on the ground, and then the top seat 2 is pressed downward. During the downward movement of the top seat 2, the force will be transmitted, so that the top seat 2 and the connecting seat 3 gradually approach the base 1.
[0029] During this process, under the action of the extrusion force, the upper reinforcement plate 41 and the lower reinforcement plate 42 are flipped outward along the connection position between the two, and gradually penetrate into the inner wall of the reinforcement hole, so that the entire reinforcement mechanism 4 is embedded in the reinforcement hole, so that the reinforcement device is formed as a whole with the ground after pouring concrete.
[0030] And during the pressurization process, the top seat 2 will drive the locking rod 44 to move synchronously, and make the locking rod 44 slide in the locking tube 45. At the same time, the locking ring 46 is embedded in the locking groove 47 to achieve the clamping fixation of the locking rod 44, thereby indirectly achieving the fixation between the upper reinforcement plate 41 and the lower reinforcement plate 42, so that the reinforcement mechanism 4 is fixed in the reinforcement hole.
[0031] Therefore, in the later stage of bored pile construction, the reinforcement mechanism 4 can provide support for the later bored piles to avoid the settlement of the bored piles, thereby achieving stable support for the soft soil foundation and providing stability in the railway construction process.
[0032] like Figure 2 , Figure 3 As shown, arc-shaped claw hooks 48 and long strip-shaped notches 49 are provided on the inner sides of the upper reinforcement plate 41 and the lower reinforcement plate 42. The claw hooks 48 are used to penetrate the notches 49 and then pierce into the reinforcement holes.
[0033] When the upper reinforcement plate 41 and the lower reinforcement plate 42 are turned over, the claw hook 48 will be driven to move synchronously, and the claw hook 48 will penetrate into the reinforcement hole after passing through the notch 49, further increasing the gripping force of the upper reinforcement plate 41 and the lower reinforcement plate 42, ensuring the stability of the entire reinforcement mechanism 4 and avoiding settlement of the cast-in-place pile.
[0034] like Figure 2 , Figure 3 As shown, the outer wall of the claw hook 48 is provided with a plurality of barbs 481 at intervals, and the barbs 481 are used to abut against the outer walls of the upper reinforcement plate 41 and the lower reinforcement plate 42. Therefore, when the claw hook 48 is inserted into the reinforcement hole, the barbs 481 can increase the grip of the claw hook 48 with the ground and increase stability, and can also clamp the upper reinforcement plate 41 and the lower reinforcement plate 42 to achieve locking between the upper reinforcement plate 41 and the lower reinforcement plate 42, thereby increasing the structural strength and stability between the upper reinforcement plate 41 and the lower reinforcement plate 42.
[0035] like Figure 5 As shown, an end cap 8 is provided below the base 1, upper support rods 81 are rotatably connected to both sides of the lower end surface of the base 1, lower support rods 82 are rotatably connected to both sides of the upper end surface of the end cap 8, the upper support rods 81 and the lower support rods 82 are rotatably connected at the middle positions, and a limiting seat 83 that interferes with each other is provided between the end cap 8 and the base 1.
[0036] When subjected to a downward force, the base 1 gradually approaches the end 8, at which time the upper support rod 81 and the lower support rod 82 flip outward and penetrate into the reinforcement hole. At the same time, under the resistance of the limiting seat 83, the base 1 and the end 8 are limited to form a whole.
[0037] Therefore, by arranging an upper support rod 81 and a lower support rod 82 that can extend out and penetrate into the reinforcement hole under the base 1, support is formed again under the entire reinforcement device to avoid settlement of the cast-in-place piles, thereby achieving stable support for the soft soil foundation.
[0038] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
