Description

Technical Field

[0001] The present invention relates to the technical field of road construction, and specifically, to a construction structure suitable for constructing roads on soft soil foundations. Background Art

[0002] Soft soil generally refers to soil layers with high natural water content, high compressibility, poor water permeability, and low shear strength, such as silt and silty soil. When such soil is subjected to external pressure, it is prone to uneven settlement, which seriously affects the stability and service life of roads. Therefore, before road construction, a construction structure suitable for constructing roads on soft soil foundations needs to be used to improve the foundation strength and overall stability of the soft soil.

[0003] After retrieval, a patent with the Chinese patent application number 201910949782.6 discloses a construction structure for constructing roads on soft soil foundations, which includes a gravel layer and a concrete layer laid successively above the soft soil layer, and also includes a number of longitudinal pine piles driven into the soft soil layer. The longitudinal pine piles are arranged on both sides along the length direction of the road surface; the upper ends of the longitudinal pine piles penetrate the gravel layer and are buried in the concrete layer, and a steel bar structure connected to the longitudinal pine piles is buried in the concrete. Through the above settings, when heavy objects such as pedestrians and vehicles are borne above the concrete layer, the bending resistance of the concrete layer is improved through the steel bar structure, and the concrete layer and the steel bar structure are supported and anchored to the longitudinal pine piles. Therefore, when the soft soil foundation under the road surface undergoes local settlement, the gravel layer around the local settlement position bears the pressure load of the concrete layer, and the longitudinal pine piles on both sides bear the tensile stress load on both sides of the concrete layer, so that the concrete layer is not easily collapsed or broken, thus protecting the lives and property safety of pedestrians on the road; The above patent still has the following deficiencies: the defects of easy slippage and deformation of soft soil. Due to the typical sponge-like or honeycomb-like structure of soft soil, with a large void ratio, high water content, small water permeability, and low strength, soft soil is prone to deformation when subjected to external forces. Under the action of high-intensity external loads, it is difficult to maintain a relatively complete structure and good structural strength, so it is prone to flow collapse. Especially in the southern region where the geological structure is complex, the groundwater environment is harsh, earthquakes are frequent, and geological disasters such as landslides, mudslides, and ground settlement are relatively serious, the phenomenon of soft soil subgrade slippage and flow is more common.

[0004] Therefore, there is an urgent need for a construction structure suitable for constructing roads on soft soil foundations to solve the above problems. Summary of the Invention

[0019] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0020] like Figures 1-9 As shown, an embodiment of the present invention provides a construction structure suitable for constructing a road on a soft soil foundation, including a fixed pile 1, and also including: A positioning cover 2 is fixed on the top of the fixing pile 1; The mounting ring 10 is welded and fixed to the outside of the fixed pile 1, and a connecting rod 8 is fixed between two adjacent groups of the mounting ring 10, and a reinforcing steel bar 9 is sleeved on the outside of the connecting rod 8; A concrete layer 3 is laid on the outside of the reinforcing steel bars 9, and a crushed stone filling layer 4 is provided at the bottom end of the concrete layer 3; The splitting structure 5 is arranged on both sides of the fixed pile 1, wherein the splitting structure 5 includes mounting grooves 503 fixed on both sides of the fixed pile 1, a partition 501 sliding inside the mounting groove 503, a ground-breaking edge 502 fixed at the bottom end of the partition 501, and an auxiliary component arranged inside the partition 501; A drainage structure 6 is arranged inside the segmentation structure 5 and is used to regulate the moisture in the surrounding soft soil; The anti-retraction structure 7 is arranged on both sides of the segmentation structure 5 to improve the anti-pullout performance of the device.

[0021] The working principle and beneficial effects of the above technical solution are as follows: in the road construction area, an excavator is used to insert multiple groups of fixed piles 1 into the soft soil at equal intervals, so that the fixed piles 1 pass through the soft soil and contact the solid soil layer deep underground, and then the dividing structure 5 is inserted into the gap between the two groups of fixed piles 1 to divide the soft soil. The drainage structure 6 facilitates the discharge of moisture in the soft soil during construction, so that engineering personnel can compact and harden the soft soil at the roadbed. Then, a crushed stone filling layer 4 is laid on the surface of the soft soil to significantly increase the compressive strength of the roadbed. The mounting ring 10 is sleeved on the outside of the fixed pile 1 and the connecting rod 8 is used to connect and fix the two adjacent groups of fixed piles 1 to share the pressure on the single group of fixed piles 1 and improve the compressive effect of the fixed pile 1. At the same time, the connecting rod 8 can be used to fix the position of the reinforcing steel bar 9, and the concrete layer 3 is formed by pouring concrete on the top of the crushed stone filling layer 4. At the same time, the reinforcing steel bars 9 and the connecting rod 8 that cross horizontally and vertically strengthen the strength and compressive strength of the concrete layer 3.

[0022] like Figure 5 and Figure 6 As shown, in one embodiment, the auxiliary component includes a fence net 505 installed inside the partition 501 and a guide plate 504 fixed on both sides of the partition 501.

[0023] The working principle and beneficial effects of the above technical solution are as follows: the partition 501 is inserted into the soft soil along the installation groove 503 to divide the soft soil. The moisture in the soft soil can pass through the partition 501 through the fence net 505. The partition 501 slides inside the installation groove 503 to guide the movement of the partition 501 so that the partition 501 is aligned with the fixed pile 1. At the same time, the partition 501 limits the position of the fixed pile 1 so that the fixed pile 1 is not easily tilted by force.

[0024] like Figure 6 As shown, in one embodiment, the front cross-section of the earth-breaking edge 502 is a “V”-shaped structure, and the guide plates 504 are evenly spaced on both sides of the partition plate 501 .

[0025] The working principle and beneficial effects of the above technical solution are: the "V"-shaped structure of the soil-breaking blade 502 allows the partition 501 to break through the soft soil and insert deep into the soft soil. At the same time, multiple sets of guide plates 504 prevent large foreign objects from contacting the fence net 505 and damaging or clogging the fence net 505.

[0026] like Figure 3 and Figure 9As shown, in one embodiment, the drainage structure 6 includes a main pipeline 601 inserted inside the gravel filling layer 4, auxiliary pipelines 602 inserted inside the gravel filling layer 4 and connected to both sides of the main pipeline 601, a housing 603 fixed inside the partition plate 501, a water suction pipe 606 inserted inside the housing 603 and communicating with the auxiliary pipeline 602, a second filter screen 605 sleeved at the bottom end of the water suction pipe 606, and a first filter screen 604 fixed inside both sides of the housing 603.

[0027] The working principle and beneficial effects of the above technical solution are as follows: By inserting the housing 603 deep into the soft soil, the water in the soft soil can enter the inside of the housing 603 through the first filter screen 604. Connect the main pipeline 601 to the water pump, so that the water pump can extract the water inside the housing 603 through the main pipeline 601, the auxiliary pipeline 602 and the water suction pipe 606, thereby discharging the water in the soft soil. After the road construction is completed, the water inside the housing 603 can still be supplemented or discharged through the main pipeline 601, the auxiliary pipeline 602 and the water suction pipe 606, controlling the water content of the soft soil at the bottom of the road, which helps to reduce the settlement and deformation of the road and extend the service life of the road. The water inhaled by the water suction pipe 606 is filtered by the housing 603 and the second filter screen 605 to prevent the water suction pipe 606 from being blocked by the soft soil.

[0028] As Figure 3 and Figure 9 As shown, in one embodiment, the water suction pipe 606 extends to the outside of the housing 603 and is connected to the auxiliary pipeline 602, and the first filter screen 604 and the partition plate 501 are integrally welded.

[0029] The working principle and beneficial effects of the above technical solution are as follows: By connecting the water suction pipe 606 to the auxiliary pipeline 602, it is convenient to suck out the accumulated water inside the housing 603, and the position of the housing 603 is fixed by the partition plate 501.

[0030] As Figure 9 As shown, in one embodiment, several groups of the first filter screens 604 are installed on both sides of the housing 603, and several groups of the first filter screens 604 are evenly distributed on both sides of the housing 603.

[0031] The working principle and beneficial effects of the above technical solution are as follows: Through multiple groups of the first filter screens 604, it is convenient to discharge the water in the soft soil at different depths and adjust the water content in the soft soil.

[0032] As Figure 8As shown, in one embodiment, the anti-withdrawal structure 7 includes fixing frames 701 fixed on both sides of the partition plate 501, a moving seat 703 sliding inside the fixing frames 701, a screw rod 702 rotatably connected inside the fixing frames 701 and threadedly connected to the moving seat 703, a push rod 707 rotatably connected to one side of the moving seat 703, a turning arm 708 rotatably connected to one side of the fixing frames 701 and rotatably connected to the push rod 707, a pressing plate 705 fixed on one side of the turning arm 708, spikes 706 fixed on one side of the pressing plate 705, and a hexagonal block 704 installed at the top end of the screw rod 702.

[0033] The working principle and beneficial effects of the above technical solution are as follows: By using a wrench or an electric screwdriver to rotate the hexagonal block 704, the hexagonal block 704 drives the screw rod 702 to rotate. At the same time, the moving seat 703 moves downward along the outer wall of the screw rod 702 by the engagement of the threads, so that the moving seat 703 pushes the turning arm 708 to turn downward through the push rod 707, opening the turning arm 708, increasing the friction between the dividing structure 5 and the ground, strengthening the dividing structure 5 and the soft soil around it, and making the dividing structure 5 not easily pulled out.

[0034] As Figure 8 shown, in one embodiment, several groups of spikes 706 are fixed on one side of the pressing plate 705, and several groups of spikes 706 are evenly distributed on one side of the pressing plate 705.

[0035] The working principle and beneficial effects of the above technical solution are as follows: By multiple groups of spikes 706, the friction between the pressing plate 705 and the soft soil is increased, so as to facilitate the anti-withdrawal structure 7 to extrude and reinforce the position of the dividing structure 5 and the soft soil around the device.

[0036] As Figure 8 shown, in one embodiment, an external thread is provided on the outer side wall of the screw rod 702, and an internal thread that cooperates with the external thread is provided inside the moving seat 703.

[0037] The working principle and beneficial effects of the above technical solution are as follows: Through the engagement of the threads, it is convenient for the screw rod 702 to drive the moving seat 703 to rise and fall, and adjust the inclination of the pressing plate 705.

[0038] As Figure 2 shown, in one embodiment, the reinforcing steel bars 9 are evenly distributed inside the concrete layer 3, and two adjacent groups of the reinforcing steel bars 9 are staggeredly distributed.

[0039] The working principle and beneficial effects of the above technical solution are as follows: The compressive capacity of the concrete layer 3 is strengthened by multiple groups of reinforcing steel bars 9, and the staggered reinforcing steel bars 9 are convenient for connecting and fixing multiple groups of connecting rods 8.

[0040] The working principle and beneficial effects of the above technical solution are as follows: in the road construction area, an excavator is used to insert multiple groups of fixed piles 1 into the soft soil at equal intervals, so that the fixed piles 1 pass through the soft soil and contact the solid soil layer deep underground, and then the splitting structure 5 is inserted into the gap between the two groups of fixed piles 1 to split the soft soil. The drainage structure 6 facilitates the discharge of moisture in the soft soil during construction, so that the engineering personnel can compact and harden the soft soil at the roadbed. Then, a crushed stone filling layer 4 is laid on the surface of the soft soil to significantly increase the compressive strength of the roadbed. The mounting ring 10 is sleeved on the outside of the fixed pile 1 and the connecting rod 8 is used to connect and fix the two adjacent groups of fixed piles 1 to share the pressure on the single group of fixed piles 1 and improve the compressive effect of the fixed pile 1. At the same time, the connecting rod 8 can be used to fix the position of the reinforcing steel bar 9, and the concrete layer 3 is formed by pouring concrete on the top of the crushed stone filling layer 4. At the same time, the reinforcing steel bars 9 and the connecting rod 8 that cross horizontally and vertically greatly reinforce the strength and compressive strength of the concrete layer 3 to complete the construction of the road.

[0041] After the fixed pile 1 is inserted, the partition 501 is inserted into the soft soil along the installation groove 503 to divide the soft soil. At the same time, the blade-shaped structure of the soil-breaking blade 502 facilitates the partition 501 to break the soft soil and insert into the deep soft soil. The moisture in the soft soil can pass through the partition 501 through the partition net 505, so that when the roadbed soft soil is compressed, it is convenient to squeeze out the moisture in the roadbed soft soil. The guide plate 504 blocks large-volume foreign objects to prevent them from contacting the partition net 505 and damaging or clogging the partition net 505. The partition 501 slides inside the installation groove 503 to guide the movement of the partition 501 so that the partition 501 is aligned with the fixed pile 1. At the same time, the partition 501 limits the position of the fixed pile 1 so that the fixed pile 1 is not easily tilted by force. The outer shell 603 is inserted deep into the soft soil so that the water in the soft soil can enter the inner part of the outer shell 603 through the first filter screen 604. The main pipeline 601 is connected with the water pump so that the water pump can extract the water inside the outer shell 603 through the main pipeline 601, the auxiliary pipeline 602 and the water suction pipe 606 to discharge the water in the soft soil. After the construction of the road is completed, the water inside the outer shell 603 can still be supplemented or discharged through the main pipeline 601, the auxiliary pipeline 602 and the water suction pipe 606 to control the water content of the soft soil at the bottom of the road, which helps to reduce the settlement and deformation of the road and extend the service life of the road. The water sucked by the water suction pipe 606 is filtered through the outer shell 603 and the second filter screen 605 to prevent the water suction pipe 606 from being blocked by the soft soil. After the splitting structure 5 is inserted into the soft soil, use a wrench or an electric screwdriver to rotate the hexagonal block 704, so that the hexagonal block 704 drives the screw 702 to rotate. At the same time, the moving seat 703 moves downward along the outer wall of the screw 702 by the engagement of the threads, so that the moving seat 703 pushes the rotating arm 708 to turn downward through the push rod 707, opening the rotating arm 708, increasing the friction between the splitting structure 5 and the ground, and at the same time strengthening the splitting structure 5 and the soft soil around it, making the splitting structure 5 not easily pulled out.
