Description

Technical Field

[0001] The present application relates to the field of landslide prevention and control, and in particular to a landslide prevention and control pile foundation. Background Art

[0002] Earthquake liquefaction refers to the liquefaction of saturated loose sand or unconsolidated rock caused by an earthquake. It can soften the foundation and bring harm to construction projects on the ground. Landslide prevention and control refers to the prevention and control measures taken when construction projects are carried out in areas where landslides cannot be avoided or where the slopes are unstable.

[0003] Under the existing technology, anti-slide piles are usually driven into the slope, and then corresponding measures are taken according to the characteristics of the slope rock mass to prevent the slope from becoming unstable and ensure the safety of production and personnel. However, the landslide prevention pile foundation structure used for preventing and controlling landslides in the existing technology is relatively simple, and the pile foundation is usually directly inserted. The reinforcement effect on the soil layer near the pile foundation is poor, and there are great risks in terms of earthquake liquefaction, so it is difficult to effectively complete the prevention and control of landslides. Utility Model Content

[0004] The purpose of the present application is to solve the problem that the landslide prevention and control pile foundation structure for preventing and controlling landslides proposed in the above-mentioned background technology is relatively simple, and the pile foundation is mostly directly inserted, the reinforcement effect of the soil layer near the pile foundation is poor, and there are great hidden dangers in terms of earthquake liquefaction, so it is difficult to effectively complete the prevention and control of landslides. The present application provides a landslide prevention and control pile foundation.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] By adopting the above technical solution, the pile tail and the auxiliary stabilizing mechanism are allowed to contact the slope surface, and then the reinforcement mechanism is opened, and the reinforcement mechanism further squeezes the soil layer around the pile rod, thereby further improving the stability of the pile rod in the slope soil layer and improving the prevention and control effect of the pile foundation.

[0008] Furthermore, the reinforcement mechanism includes two connecting rods symmetrically arranged on the pile rod, the connecting rods are rotatably connected to the pile rod, a reinforcement plate is fixed on the connecting rod, a through groove is opened on the pile rod, the reinforcement plate is located in the through groove, and a pushing assembly is provided on the pile rod.

[0009] By adopting the above technical solution, the pushing component drives the two reinforcement plates, which are opened under the support of the two connecting rods. The reinforcement plates squeeze the surrounding soil layers, and then the reinforcement plates are buckled on the squeezed soil layers, thereby further improving the stability of the pile rod on the slope.

[0010] Furthermore, the pushing assembly includes a pushing threaded rod threadedly connected to the pile rod, and the end of the pushing threaded rod close to the pile head is rotatably connected to a rotating block, and a pushing block is fixed on the rotating block.

[0011] By adopting the above technical solution, the pushing threaded rod squeezes the rotating block, and the rotating block squeezes the pushing block, so that the two reinforcement plates are opened at the same time, thereby reducing the displacement of the pile rod when the reinforcement plates contact the soil layer in the slope.

[0012] Furthermore, a plurality of limit pins are arranged on the pile rod, the limit pins penetrate the pile rod and are slidably connected to the pile rod, one end of the limit pin is in a pointed cone shape, and the other end of the limit pin is provided with an inclined surface, which corresponds to the inclined surface of the push block.

[0014] Furthermore, a plurality of stabilizing plates distributed in a circumference are arranged on the pile rod, and the stabilizing plates are fixedly connected to the pile rod.

[0015] By adopting the above technical solution, the stabilizing plate can enter the soil layer together with the pile rod, thereby increasing the contact area between the pile rod and the soil layer, thereby increasing the contact area between the pile rod and the soil layer and reducing the possibility of pile rod rotation.

[0016] Furthermore, the auxiliary stabilization mechanism includes three rotating shafts rotatably connected to the pile tail in a circular distribution, the pile tail is provided with three circumferentially distributed interference grooves, the interference grooves are right-angle grooves, the rotating shaft is located in the interference grooves, a interference plate is fixed on the rotating shaft, and evenly distributed interference teeth are fixed on the interference plate.

[0017] By adopting the above technical solution, the contact plate and the pile tail contact the slope together, and the contact teeth on the contact plate contact the slope to increase friction, thereby improving the stability of the pile tail and further improving the stability of the pile rod.

[0018] Furthermore, a fixing rod is slidably connected to the abutment plate, and the fixing rod passes through the abutment plate. Fixing grooves are provided on two right-angled surfaces of the abutment groove.

[0020] Furthermore, the reinforcement plate is provided with two symmetrical reinforcement ribs, and the reinforcement ribs are fixedly connected to the reinforcement plate.

[0021] By adopting the above technical solution, when the reinforcement plate contacts the soil layer, the reinforcing ribs move with the reinforcement plate, thereby reducing the possibility of deformation and fracture of the reinforcement plate when squeezing the soil layer.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. The present application sends the pile rod into the slope surface under the action of the pile head, allows the stabilizing plate to enter the soil layer along with the pile rod, allows the pile tail and the abutment plate to abut on the slope surface, and then rotates and pushes the threaded rod to allow the pushing threaded rod to squeeze the rotating block, the rotating block squeezes the pushing block, the pushing block squeezes the pushing groove between the two reinforcing plates, the two reinforcing plates are opened at the same time, the reinforcing plates squeeze the surrounding soil layers, and then the reinforcing plates are buckled on the squeezed soil layers, the reinforcing plates restrict the pile rod, and during the movement of the pushing block, the pushing block squeezes the inclined surface of the limiting nail, so that when the pile rod is sent into the soil layer in the slope, the reinforcing plate is used to squeeze the surrounding soil layers, which can further improve the stability of the pile rod in the slope soil layer, improve the prevention and control effect of the pile foundation, and reduce the possibility of pile rod movement.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a landslide prevention pile foundation.

[0032] Reference Figure 1 , Figure 2 and Figure 3 A pile foundation for landslide prevention and control includes a pile rod 1, a pile head 2 is fixed at one end of the pile rod 1, the inclined surface of the pile head 2 is in a pointed cone shape, a pile tail 3 is fixed at one end of the pile rod 1 away from the pile head 2, the pile rod 1 is hollow, the pile tail 3 is in a disc shape, a reinforcement mechanism 4 is arranged on the pile rod 1, and an auxiliary stabilization mechanism 5 is arranged on the pile tail 3. When the pile foundation is needed, the auxiliary stabilization mechanism 5 is first opened on the pile tail 3, and then the pile head 2 on the pile rod 1 is aligned with the slope surface, and the pile rod 1 is sent into the slope surface under the action of the pile head 2, so that the pile tail 3 and the auxiliary stabilization mechanism 5 are in contact with the slope surface, and then the reinforcement mechanism 4 is opened, and the reinforcement mechanism 4 further squeezes the soil layer around the pile rod 1. When the pile rod 1 is sent into the soil layer in the slope, the reinforcement mechanism 4 is used to squeeze the soil layer around, so that the stability of the pile rod 1 in the slope soil layer can be further improved, and the prevention and control effect of the pile foundation can be improved.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The reinforcement mechanism 4 includes two connecting rods 42 symmetrically arranged on the pile rod 1. The connecting rods 42 are rotatably connected to the pile rod 1. A reinforcement plate 41 is fixed on the connecting rod 42. A through groove is provided on the pile rod 1. The reinforcement plate 41 is located in the through groove. A pushing assembly 43 is provided on the pile rod 1. After the pile rod 1 is sent into the soil layer, the pushing assembly 43 is used to move in the pile rod 1, so that the pushing assembly 43 drives the two reinforcement plates 41. The reinforcement plates 41 are opened under the support of the two connecting rods 42. The reinforcement plates 41 squeeze the surrounding soil layer, and then the reinforcement plates 41 are buckled on the squeezed soil layer. The reinforcement plates 41 restrict the pile rod 1. By using the reinforcement plates 41 to open and buckle on the slope soil layer, the stability of the pile rod 1 on the slope can be further improved.

[0034] Reference Figure 2 and Figure 3The pushing assembly 43 includes a pushing threaded rod 433 threadedly connected to the pile rod 1. The end of the pushing threaded rod 433 close to the pile head 2 is rotatably connected to a rotating block 434. A pushing block 432 is fixed on the rotating block 434. The pushing block 432 is in a truncated cone shape. A pushing groove 431 is provided between the two reinforcing plates 41. The pushing groove 431 corresponds to the pushing block 432. When the pile rod 1 is sent into the slope soil layer, the pushing threaded rod 433 is rotated to allow the pushing threaded rod 433 to squeeze the rotating block 434, and the rotating block 434 squeezes the pushing block 432. The pushing block 432 squeezes the pushing groove 431 between the two reinforcing plates 41, so that the two reinforcing plates 41 are opened at the same time. By using the pushing threaded rod 433 to drive the pushing block 432, the pushing block 432 is allowed to contact the two reinforcing plates 41, and the two reinforcing plates 41 are allowed to open at the same time, so that the reinforcing plates 41 can reduce the displacement of the pile rod 1 when they contact the soil layer in the slope.

[0035] Reference Figure 2 and Figure 3 , a plurality of limit pins 44 are arranged on the pile rod 1, the limit pins 44 penetrate the pile rod 1, and are slidably connected with the pile rod 1, one end of the limit pin 44 is in a pointed cone shape, and the other end of the limit pin 44 is provided with an inclined surface, which corresponds to the inclined surface of the push block 432. When the push block 432 squeezes the reinforcement plate 41, the push block 432 squeezes the inclined surface of the limit pin 44, so that the limit pin 44 extends out from the pile head 2, and the limit pin 44 is inserted into the soil layer, and the limit pin 44 further limits the pile rod 1. By allowing the limit pin 44 to penetrate into the soil layer during the movement of the push block 432, the stability of the pile rod 1 can be further improved when the reinforcement plate 41 squeezes the slope soil layer.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The pile rod 1 is provided with a plurality of stabilizing plates 45 distributed in a circumference, and the stabilizing plates 45 are fixedly connected to the pile rod 1. When the pile rod 1 is sent into the slope soil layer, the stabilizing plates 45 are allowed to enter the soil layer along with the pile rod 1 to increase the contact area between the pile rod 1 and the soil layer. At the same time, when the threaded rod 433 is rotated and pushed, the stabilizing plates 45 play a role of limiting. By allowing the stabilizing plates 45 to enter the slope soil layer along with the pile rod 1, the contact area between the pile rod 1 and the soil layer can be increased, and the possibility of the pile rod 1 rotating can be reduced.

[0037] Reference Figure 1 , Figure 2 and Figure 3The auxiliary stabilizing mechanism 5 includes three rotating shafts 51 rotatably connected to the pile tail 3 in a circumferential distribution. The pile tail 3 is provided with three circumferentially distributed conflicting grooves 52, which are right-angle grooves. The rotating shaft 51 is located in the conflicting grooves 52. A conflicting plate 53 is fixed on the rotating shaft 51, and conflicting teeth 54 distributed evenly are fixed on the conflicting plate 53. When the pile rod 1 is inserted into the soil layer, the conflicting plate 53 is opened on the pile tail 3, so that the conflicting plate 53 is flush with the pile tail 3 under the restriction of the conflicting grooves 52, and then the conflicting plate 53 and the pile tail 3 are contacted on the slope together, and the conflicting teeth 54 on the conflicting plate 53 are contacted on the slope to increase friction. By opening the conflicting plate 53, the conflicting plate 53 increases the conflicting area between the pile tail 3 and the slope, and at the same time increases the friction between the pile tail 3 and the slope, thereby improving the stability of the pile tail 3 and further improving the stability of the pile rod 1.

[0038] Reference Figure 1 and Figure 2 A fixing rod 55 is slidably connected to the abutment plate 53, and the fixing rod 55 penetrates the abutment plate 53. The fixing grooves are provided on the two right-angled surfaces of the abutment groove 52. When the abutment plate 53 is not in use, the fixing rod 55 on the abutment plate 53 is inserted into the corresponding fixing groove, so that the abutment plate 53 is folded up, which is convenient for the transportation of the pile pole 1. When it is needed, the abutment plate 53 is opened, and then the fixing rod 55 is inserted into another fixing groove and threadedly connected. By using the fixing rod 55 to restrict the abutment plate 53, the back and forth movement of the abutment plate 53 when it is folded up or opened can be reduced, thereby improving the stability of the abutment plate 53 on the pile tail 3.

[0039] Reference Figure 1 and Figure 2 Two symmetrical reinforcing ribs 6 are arranged on the reinforcing plate 41, and the reinforcing ribs 6 are fixedly connected to the reinforcing plate 41. The reinforcing ribs 6 are fixed on the reinforcing plate 41, and when the reinforcing plate 41 contacts the soil layer, the reinforcing ribs 6 move with the reinforcing plate 41, and the strength of the reinforcing plate 41 is increased by using the reinforcing ribs 6, so that the possibility of deformation and fracture of the reinforcing plate 41 when squeezing the soil layer can be reduced.

[0040] Working principle: when the pile foundation is needed, the contact plate 53 is opened, and then the fixing rod 55 is inserted into the fixing groove and threadedly connected, the contact plate 53 is opened and fixed, and then the pile rod 1 is sent into the slope surface under the action of the pile head 2, and the stabilizing plate 45 is also entered into the soil layer with the pile rod 1, and the pile tail 3 and the contact plate 53 are in contact with the slope surface, and then the threaded rod 433 is rotated and pushed, and the threaded rod 433 is pushed to squeeze the rotating block 434, and the rotating block 434 squeezes the pushing block 432. The pushing block 432 squeezes the pushing groove 431 between the two reinforcing plates 41, allowing the two reinforcing plates 41 to open at the same time, and the reinforcing plates 41 squeeze the surrounding soil layer, and then the reinforcing plates 41 are buckled on the squeezed soil layer, and the reinforcing plates 41 restrict the pile rod 1. During the movement of the pushing block 432, the pushing block 432 squeezes the inclined surface of the limiting nail 44, allowing the limiting nail 44 to extend from the pile head 2, allowing the limiting nail 44 to penetrate into the soil layer, and the limiting nail 44 further restricts the pile rod 1 to complete the construction of the pile foundation.
