Description

Technical Field

[0001] This utility model relates to the field of precast pipe pile construction technology, specifically a vertical guide structure for precast pipe pile construction in soft soil areas. Background Technology

[0002] Prestressed concrete pipe piles, through high-strength concrete and prestressing technology, have excellent compressive and bending resistance, making them suitable for the high load requirements of high-rise buildings. Compared with other types of pile foundations, prestressed concrete pipe piles have the advantages of fast construction efficiency, high bearing capacity, stable quality, good environmental performance, strong adaptability, and high economic benefits.

[0003] In areas with deep soft soil, the soil is soft and lacks strength, making it difficult to control its verticality during construction and causing soil squeezing effects, which affect the support effect of prestressed concrete pipe piles after installation. Therefore, a vertical guide structure for the construction of precast pipe piles in soft soil areas is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical guide structure for the construction of precast pipe piles in soft soil areas, so as to solve the problem that the insufficient strength of the soft soil itself in deep soft soil areas affects the support effect of the prestressed concrete pipe piles after installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A vertical guide structure for precast pipe pile construction in soft soil areas includes a base plate and a horizontal device. A through hole is provided in the center of the base plate. Mounting shells are installed on both sides of the through hole in the base plate. Mounting plates are installed inside the mounting shells. A support plate is fixedly connected to the top of the mounting plate. A U-shaped frame is provided through the support plate. Bolts that are rotatably connected to the support plate are threaded into the U-shaped frame. Two U-shaped frames are provided in one support plate, which are respectively distributed vertically. A horizontal device is installed in front of the two U-shaped frames in the same support plate. A longitudinally arranged rotating roller is rotatably connected to the end of the U-shaped frame away from the bolt.

[0006] Preferably, a fixing sleeve is fixedly connected to each of the four corners of the top of the base plate, and a plug rod is inserted through the fixing sleeve. The plug rod penetrates the base plate, and a connecting rod is provided on the left and right sides of the top of the base plate. Vertically arranged plug rods are fixedly connected to the bottom front and rear sides of the connecting rod.

[0007] Preferably, the leveling device includes a housing, a fixed plate, a rotating rod, a sliding plate, and a level. Fixed plates are installed on both the upper and lower sides of the housing by screws. A rotating rod is installed through the fixed plate. A sliding plate is fixedly connected to one end of the rotating rod inside the housing. The rear side of the rotating rod away from the sliding plate is rotatably connected to a U-shaped frame. Two levels are fixedly connected to the front side of the housing in an up-down distribution.

[0008] Preferably, the horizontal device further includes a slide rod and a limiting spring. The fixed plate has two slots arranged symmetrically on one side. The slide rod is installed in the slot of the fixed plate and passes through the slide plate. Limiting springs are installed on the outer sides of both ends of the slide rod.

[0009] Preferably, one end of the limiting spring is tightly fitted to the fixed plate, and the other end of the limiting spring is tightly fitted to the sliding plate, with the two sliding rods respectively arranged on the left and right sides of the rotating rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting a base plate, mounting shell, mounting plate, support plate, U-shaped frame, rotating roller and bolt, after the base plate is placed in a suitable position, the U-shaped frame connected to it by the bolt is moved by the bolt, and the U-shaped frame drives the rotating roller to move, thereby adjusting so that the left and right sides of the two rotating rollers set on one side of the support plate are on the same vertical plane. When the soft soil surface collapses and the base plate is not level, the position of the rotating roller can be manually adjusted so that the rotating roller can accurately guide the precast pipe pile vertically. The mounting shell and mounting plate can make the installation of the support plate more stable. 2. In this utility model, the base plate, fixing sleeve, insert rod and connecting rod are provided. The insert rod can be directly inserted into the soil through the fixing sleeve and the base plate to limit the position of the base plate. At the same time, the insert rod is inserted vertically into the soil, which can reduce the impact of soft soil surface collapse on the level of the base plate. The connecting rod connecting the two insert rods can install and disassemble a pair of insert rods at the same time, which is convenient for the use of the insert rods. 3. In this utility model, the outer shell, fixed plate, rotating rod, sliding plate, sliding rod, slot, limiting spring, and level are designed to drive the rotating rod to move when the U-shaped frame moves. The two rotating rods rotate on the front side of the two U-shaped frames respectively, and at the same time, the rotating rod drives the outer shell to rotate. The rotating rod drives the sliding plate to move inside the outer shell. At this time, the limiting spring can use its own elasticity to set the outer shell in a relatively horizontal position outside the rotating rod, so that the level fixedly connected to the front side of the outer shell can detect the level more accurately. When the level shows a horizontal state, the left and right sides of the two rotating rollers set on one side of the support plate are on the same vertical plane, which makes the vertical direction guidance during the construction of precast pipe piles more accurate.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 This utility model provides a technical solution: A vertical guide structure for precast pipe pile construction in soft soil areas includes a base plate 1 and a horizontal device 8. A through hole 12 is provided in the center of the base plate 1. Mounting shells 2 are installed on both sides of the through hole 12. Mounting plates 3 are installed inside the mounting shells 2. A support plate 4 is fixedly connected to the top of the mounting plate 3. A U-shaped frame 5 is threaded through the support plate 4. Bolts 7, which are rotatably connected to the support plate 4, are threaded into the U-shaped frame 5. Two U-shaped frames 5 are arranged vertically within each support plate 4. A horizontal device is installed in front of the two U-shaped frames 5 within the same support plate 4. 8. A longitudinally arranged rotating roller 6 is rotatably connected to the end of the U-shaped frame 5 away from the bolt 7. With this arrangement, after the base plate 1 is placed in a suitable position, the U-shaped frame 5, which is threadedly connected to it, can be moved by the bolt 7. The U-shaped frame 5 moves the rotating roller 6, thereby adjusting so that the left and right sides of the two rotating rollers 6 on one side of the support plate 4 are on the same vertical plane. When the soft soil surface collapses and the base plate 1 is not level, the position of the rotating roller 6 can be manually adjusted so that the rotating roller 6 can accurately guide the precast pipe pile vertically. The installation shell 2 and the installation plate 3 can make the installation of the support plate 4 more stable.

[0015] Fixed sleeves 9 are fixedly connected to the four corners of the top of the base plate 1. Inserted rods 10 are inserted through the fixed sleeves 9 and penetrate the base plate 1. Connecting rods 11 are provided on the left and right sides of the top of the base plate 1. Vertically inserted rods 10 are fixedly connected to the bottom front and rear sides of the connecting rods 11. With this arrangement, the inserted rods 10 can be directly inserted into the soil through the fixed sleeves 9 and the base plate 1, thereby limiting the position of the base plate 1. At the same time, the vertical insertion of the inserted rods 10 into the soil can reduce the impact of soft soil surface collapse on the levelness of the base plate 1. The connecting rods 11 connecting two inserted rods 10 can simultaneously support a pair of... The insertion rod 10 is installed and disassembled for easy use. The leveling device 8 includes a housing 801, a fixing plate 802, a rotating rod 803, a sliding plate 804, and a level 808. The fixing plate 802 is installed on both the upper and lower sides of the housing 801 by screws. The rotating rod 803 is inserted through the fixing plate 802. One end of the rotating rod 803 inside the housing 801 is fixedly connected to the sliding plate 804. The rear side of the rotating rod 803 away from the sliding plate 804 is rotatably connected to the U-shaped frame 5. Two levels 808 distributed vertically are fixedly connected to the front side of the housing 801. The leveling device 8 also includes a sliding rod 808. 05 and limiting spring 807, the fixed plate 802 has two slots 806 arranged symmetrically on one side, and a slide rod 805 is installed in the slot 806 of the fixed plate 802. The slide rod 805 passes through the slide plate 804. Limiting springs 807 are installed on the outer sides of both ends of the slide rod 805. One end of the limiting spring 807 is tightly attached to the fixed plate 802, and the other end of the limiting spring 807 is tightly attached to the slide plate 804. The two slide rods 805 are respectively set on the left and right sides of the rotating rod 803. With this arrangement, the rotating rod 803 can be moved when the U-shaped frame 5 moves. 03 rotates on the front side of the two U-shaped frames 5 respectively. At the same time, the rotating rod 803 drives the outer shell 801 to rotate. The rotating rod 803 drives the sliding plate 804 to move inside the outer shell 801. At this time, the limiting spring 807 can use its own elasticity to set the outer shell 801 in a relatively horizontal position outside the rotating rod 803. This makes the level 808 fixedly connected to the front side of the outer shell 801 more accurate in detecting the level. When the level 808 shows a horizontal state, the left and right sides of the two rotating rollers 6 set on one side of the support plate 4 are on the same vertical plane, making the vertical direction guidance during the construction of precast pipe piles more accurate.

[0016] Workflow: When using the vertical guide structure for precast pipe pile construction in soft soil areas, first, lay the base plate 1 in a suitable position on the ground. Then, align the through hole 12 with the location where the precast pipe pile needs to be constructed. Next, insert the insertion rod 10 through the fixing sleeve 9 and the base plate 1 into the soil to position the base plate 1. At this time, observe whether the level 808 is level. If the level 808 is not level, rotate one bolt 7. At this time, the bolt 7 rotates on one side of the support plate 4. Simultaneously, the bolt 7 drives the threaded U-shaped frame 5 to slide within the support plate 4. The U-shaped frame 5 drives the rotating roller 6 to move. At this time, the U-shaped frame 5 drives the rotating rod 803 to move. At this time, the two rotating rods 803 set on the same side of the support plate 4 rotate on the two sides of the two U-shaped frames 5 respectively. At this time, the rotating rod 803 pushes the sliding plate 804 to slide inside the outer shell 801. At the same time, the sliding plate 804 slides outside the sliding rod 805. The limiting spring 807 is compressed by force. The limiting spring 807 makes the outer shell 801 more stable outside the two rotating rods 803 until the outer shell 801 is set vertically. At this time, the two levels 808 set on the front side of one outer shell 801 both show a horizontal state. At the same time, the left and right sides of the two rotating rollers 6 set on one side of the same support plate 4 are on the same vertical plane. Then, the precast pipe pile is lifted by the lifting device for installation. At this time, the rotating roller 6 can limit and guide the precast pipe pile, so that the precast pipe pile can move vertically downward until the precast pipe pile penetrates the through hole 12 opened in the bottom plate 1 and is inserted into the ground.
