Description

Technical Field

[0001] This utility model relates to the field of soft soil foundation reinforcement technology, and in particular to a soft soil foundation reinforcement structure for municipal roads. Background Technology

[0002] Because soft soil foundations are characterized by high porosity, high water content, and large settlement, they are not suitable for direct construction of road projects, water conservancy projects, etc. They need to be reinforced before construction. However, with the continuous development of infrastructure construction in my country, it is inevitable that a large number of building projects, road projects, water conservancy projects, etc. will be built on soft soil foundations.

[0003] In existing construction, reinforcement structures for soft soil foundations are made by inserting cement piles into the soft soil foundation to stabilize it.

[0004] Because soft soil is prone to large settlement, gaps will appear between the sidewalls of the soft soil foundation and the sidewalls of the reinforcement structure after the reinforcement structure is installed, which will significantly reduce the reinforcement effect of the reinforcement structure on the soft soil foundation. Utility Model Content

[0005] To overcome the aforementioned drawbacks, this utility model provides a structure for reinforcing soft soil foundations for municipal roads.

[0006] The technical solution of this utility model is: a soft soil foundation reinforcement structure for municipal roads, including a foundation pit opened on the ground, several bases installed in the foundation pit, a top plate slidably connected to the base, a material discharge port opened on the top plate, and reinforcement components and stabilization components. The reinforcement components include reinforcement piles, and reinforcement piles are slidably embedded in the bases near the side wall of the foundation pit. Several second through holes are opened at the ends of the reinforcement piles, and stabilization components are installed at the bottom of the bases.

[0007] Preferably, the reinforcement component also includes a rotating triangular plate, and the outer wall of the reinforcement pile has several second row outlets, each of which is rotatably connected to a rotating triangular plate.

[0008] Preferably, the stabilizing component includes a pile, and the bottom of several bases are rotatably connected to the pile, with several first through holes arranged in a circumferential array at the bottom of the pile.

[0009] Preferably, the stabilizing component also includes a disc, which is slidably connected to the inner wall of the pile. The outer wall of the disc has several rectangular openings arranged in a circular array. Each rectangular opening is rotatably connected to a guide body. One end of the guide body is rotatably connected to an arc plate. The arc plate is slidably connected to the pile. The pile has a first row of outlets located at the arc plate.

[0010] Preferably, the stabilizing component also includes a connecting rod, which is fixedly connected inside the pile, slidably connected to the disc, with the top of the connecting rod extending through to the outside of the pile, and a cross spline provided at the top of the connecting rod.

[0011] Preferably, the stabilizing component also includes a spiral guide plate, which is fixedly connected inside the pile. The pile has a spiral groove above the thread line of the spiral guide plate, and a rectangular opening fixedly connected to the top plate is provided above one end of the spiral guide plate.

[0012] Preferably, the stabilizing component also includes a spiral baffle, with the spiral baffle fixed to the top surface of the spiral guide plate and several agitator plates fixed to the outer wall of the pile.

[0013] Preferably, it also includes a top strip, with the bottom of the base symmetrically connected to the top strip, and the top of the top strip can contact the bottom of the top plate.

[0014] The beneficial effects of this utility model are as follows: By setting up the reinforcement components, concrete will flow into the reinforcement pile through the base. Part of the concrete inside the reinforcement pile will flow into the soft soil through the second through hole. As the amount of concrete inside the reinforcement pile increases, the concrete will push the rotating triangle plate to rotate and open, so that the second outlet will open. At this time, part of the concrete will flow into the soft soil through the second outlet. It should be noted that after the rotating triangle plate is opened, it forms a barbed state. When the concrete flows into the soft soil guided by the rotating triangle plate, it will also form a barbed state after solidification. The barbed shape can strengthen the connection between the base and the side wall of the foundation pit, thereby improving the reinforcement effect of the base and the foundation pit.

Detailed Implementation

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] A structure for reinforcing soft soil foundations for municipal roads, such as... Figures 1-7 As shown, the structure includes a foundation pit 1 opened on the ground, several bases 2 installed in the foundation pit 1, a top plate 3 slidably connected to the base 2, a discharge port 301 on the top plate 3, and reinforcement components and stabilizing components. The reinforcement components include reinforcement piles 6. Reinforcement piles 6 are embedded and slidably connected to the bases 2 near the side wall of the foundation pit 1. The bases 2 are connected to the reinforcement piles 6. Several second through holes 603 are opened at the ends of the reinforcement piles 6. Stabilizing components are installed at the bottom of the bases 2.

[0026] The reinforcement component also includes a rotating triangular plate 602. The outer wall of the reinforcement pile 6 has several second row outlets 601, and each second row outlet 601 is rotatably connected to a rotating triangular plate 602.

[0027] The stabilizing component includes a pile 5, and the bottom of several bases 2 are rotatably connected to the pile 5. The bases 2 and the piles 5 are interconnected. Several first through holes 506 are arranged in a circular array on the bottom of the pile 5.

[0028] The stabilizing component also includes a disc 501, which is slidably connected to the inner side of the pile 5. The outer wall of the disc 501 has several rectangular openings 502 arranged in a circular array. Each rectangular opening 502 is rotatably connected to a guide body 503. One end of the guide body 503 is rotatably connected to an arc plate 504. The arc plate 504 is slidably connected to the pile 5. The pile 5 has a first row of outlets 505 corresponding to the arc plate 504. The arc plate 504 can be fitted into the pile 5 through the first row of outlets 505.

[0029] The stabilizing component also includes a connecting rod 701, which is fixedly connected inside the pile 5. The connecting rod 701 is slidably connected to the disc 501. The top of the connecting rod 701 extends through to the outside of the pile 5. The top of the connecting rod 701 is provided with a cross spline. The top surface of the connecting rod 701 is flush with the top surface of the base 2.

[0030] The stabilizing component also includes a spiral guide plate 702, which is fixedly connected to the inside of the pile 5. The side wall of the pile 5 is provided with a spiral groove 704 above the thread line of the spiral guide plate 702. A rectangular through-hole 705 fixedly connected to the top plate 3 is provided at the top of the spiral guide plate 702.

[0031] The stabilizing components also include a spiral baffle 703, the top surface of the spiral guide plate 702 is fixedly connected to the spiral baffle 703, and a number of agitator plates 706 are fixedly connected to the outer wall of the pile 5.

[0032] It also includes a top strip 4, which is symmetrically connected to the bottom of the base 2. The top of the top strip 4 can contact the bottom of the top plate 3, and the top strip 4 can prevent the bottom surface of the top plate 3 from contacting the top surface inside the base 2.

[0033] First, a foundation pit 1 is excavated in the soft soil. Then, several bases 2 are installed inside the foundation pit 1. During the installation of the bases 2, the piles 5 and the stirring plate 706 are pressed into the soft soil to maintain the stability of the bases 2. When the bottom surface of the base 2 contacts the bottom surface of the foundation pit 1, and the left and right bases 2 contact the side walls of the foundation pit 1, it indicates that the installation of the bases 2 is complete. Then, multiple reinforcing piles 6 are inserted into the soft soil through the side walls of the bases 2. Subsequently, a curing agent pipeline is connected to the rectangular opening 705 to deliver the curing agent into the piles 5. After passing through the rectangular opening 705, the curing agent falls onto the spiral guide plate 702 and flows downward spirally with the spiral guide plate 702. The spiral baffle 703 can block the curing agent, and the curing agent flows along... When the curing agent flows along the spiral guide plate 702, a certain centrifugal force is generated. Some of the curing agent can flow towards the spiral groove 704 through this centrifugal force, and thus flow into the soft soil through the spiral groove 704. The curing agent that does not flow out through the spiral groove 704 will fall onto the disc 501. Since the disc 501 and the rectangular opening 502 are not sealed, the curing agent on the disc 501 will flow from the rectangular opening 502 to the bottom of the pile 5, and finally flow into the soft soil through the first through hole 506. After the curing agent is added, the rectangular opening 705 is no longer connected to the external curing agent pipeline. The cross spline at the top of the connecting rod 701 is connected to the external motor. When the motor is started, the motor drives the pile 5 to rotate through the connecting rod 701. The pile 5 drives the stirring plate 70 6. The synchronous rotation of the stirring plate 706 agitates the soft soil and the hardener within it, allowing for a more thorough integration of the soft soil and hardener. The motor is then stopped, and its connection to the cross-shaped spline at the top of the connecting rod 701 is severed. Concrete is then filled into the base 2 through the discharge port 301. The concrete flows into the pile 5 through the base 2, where it presses against the disc 501, causing it to slide downwards. At this point, the disc 501 pushes the arc-shaped plate 504 outwards via the guide body 503, opening the first outlet 505. Due to the soft soil, the arc-shaped plate 504 slides outwards relatively smoothly. After the first outlet 505 opens, some concrete flows along the guide body 503... 3. The concrete flows into the soft soil and is located around the pile 5. At the same time, since the disc 501 and the rectangular opening 502 are not sealed, some concrete will flow into the bottom of the pile 5 through the rectangular opening 502 and into the soft soil through the first through hole 506. It should be noted that the concrete flowing into the soft soil from inside the pile 5 is located around the pile 5, and the concrete in the soft soil is connected to the concrete inside the pile 5. Therefore, the concrete in the soft soil can further reinforce the pile 5, making the installation of the base 2 more stable. At the same time, due to the pressure of the soft soil itself, only a portion of the concrete will flow into the soft soil, and there will not be a situation where all the concrete flows into the soft soil.

[0034] As the amount of concrete inside pile 5 increases, it will slowly emerge from the top of pile 5. Due to the design of the top strip 4, the bottom surface of the top plate 3 does not contact the top surface inside the base 2. The concrete emerging from the top of pile 5 will gradually fill the space inside the base 2 and between the two top strips 4. As the amount of concrete inside the base 2 increases, the concrete will push the top plate 3 upward, causing it to slide upward. When the top plate 3 slides upward and passes the connection between the reinforcing pile 6 and the base 2, the concrete will flow into the reinforcing pile 6 through the base 2. Some of the concrete inside the reinforcing pile 6 will flow into the soft soil through the second through hole 603. As the amount of concrete inside the reinforcing pile 6 increases, the pressure of the concrete inside the reinforcing pile 6 will increase. When the concrete pressure increases to a threshold, it will push the triangular plate 602 at the bottom of the reinforcing pile 6 to rotate and open, causing the second outlet 601 at the bottom to open. At this time, some concrete will flow through... The second row of outlets 601 at the bottom flows into the soft soil. The concrete inside the reinforcing pile 6 continues to increase, and the pressure of the concrete continues to increase. At this time, the concrete will push the triangular plates 602 on the front and rear sides of the reinforcing pile 6 to rotate and open, so that the second row of outlets 601 on the front and rear sides will open. At this time, some concrete will also flow into the soft soil through the second row of outlets 601 on both sides. Subsequently, the concrete inside the reinforcing pile 6 continues to increase, eventually causing the concrete to push the triangular plate 602 at the top of the reinforcing pile 6 to rotate and open. Some concrete will flow into the soft soil through the second row of outlets 601 at the top. It should be noted that after the triangular plate 602 is opened, it forms a barbed state. When the concrete flows into the soft soil guided by the triangular plate 602, it will also form a barbed state after solidification. The barbed shape can strengthen the connection between the base 2 and the side wall of the pit 1, thereby improving the reinforcement effect between the base 2 and the pit 1.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
