Description

Technical Field

[0001] This invention relates to the technical field of rainwater pipe structure and installation method, specifically a prefabricated assembled rainwater pipe structure and its assembly method. Background Technology

[0002] Pipe foundations are an essential component of piping systems. In my country, drainage and sewage pipes typically have diameters of 0.2-3 meters, and are primarily made of reinforced concrete and PVC. Before installation, a 100mm thick C15 plain concrete layer or a 200-300mm thick crushed stone layer is usually laid at the bottom of the trench, meeting design requirements. After the layer reaches the required strength, reinforcing bars are tied to it, formwork is installed, and concrete foundations are poured. The foundations are then cured until they reach the required strength before the formwork is removed, and finally, the pipes are installed. However, this method of using a concrete layer to create pipe foundations sometimes fails to meet the actual engineering needs.

[0003] However, in practical applications, the traditional method for installing precast concrete pipes on the inner wall of a vertical shaft is to use a sinking method. This method requires a large pipe-lifting machine to lift the upper concrete pipe, which is costly. Additionally, it is not convenient to adjust the flatness of the open ends of the two concrete pipes inside the shaft. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated assembled rainwater pipe structure and its assembly method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated assembled rainwater pipe structure and its assembly method, comprising a prefabricated concrete pipe one and a prefabricated concrete pipe three, wherein a plastic connecting pipe is fixedly installed on the inner wall of the prefabricated concrete pipe one, and the plastic connecting pipe is fixedly inserted through and into the interior of the prefabricated concrete pipe three; and assembly mechanisms are provided on the surfaces of the prefabricated concrete pipe one and the prefabricated concrete pipe three.

[0006] The assembly mechanism includes a mounting side plate base, which is disposed on one side of precast concrete pipe one and precast concrete pipe three. A piston cylinder is fixedly mounted on the surface of the mounting side plate base. A telescopic column is inserted into the piston cylinder. A compression spring is fixedly mounted on the surface of the telescopic end of the telescopic column, and damping oil is disposed inside the piston cylinder. A mounting bearing plate is fixedly mounted on one end of the telescopic column. The mounting bearing plate has a tile-shaped structure. Precast concrete pipe one and precast concrete pipe three are disposed inside the mounting bearing plate during installation. A column is fixedly mounted on the surface of the mounting side plate base. A support platform is fixedly mounted on one end of the column. A hydraulic cylinder is fixedly mounted on the surface of the support platform. A push block is fixedly mounted on one end of the telescopic end of the hydraulic cylinder. A through groove is opened inside the push block, and a transparent glass is installed therein. A vertical ruler is disposed inside the push block. The surface of the push block away from the hydraulic cylinder is fixedly connected to the surface of the mounting bearing plate.

[0007] Preferably, the upper and lower ends of the mounting side plate base are fixedly provided with soil-breaking blades, one side of which is knife-shaped and is used to break the soil and descend inside the shaft.

[0008] Preferably, the number of hydraulic cylinders is four, and a connecting horizontal plate is fixedly provided on the peripheral surface of the telescopic end of the four hydraulic cylinders, and the connecting horizontal plate is used to uniformly drive the telescopic end of the hydraulic cylinders to move.

[0009] Preferably, a connecting component is fixedly provided on the circumferential surface of the telescopic column, the connecting component including a vertical plate connecting the column.

[0010] Preferably, a bracket is fixedly provided at one end of the connecting cylinder of the connecting assembly, a high-power motor is fixedly provided on the inner wall of the bracket, an inner horizontal plate is fixedly provided on the inner wall of the mounting bearing plate, a circular through groove is opened in the inner side of the inner horizontal plate, and the output shaft of the high-power motor moves through and extends to the other end of the inner horizontal plate.

[0011] Preferably, a reducer is fixedly installed at one end of the output shaft of the high-power motor, and a transmission rectangular column is fixedly installed at one end of the transmission shaft of the reducer.

[0012] Preferably, a rotating column is fixedly installed at the end of the transmission rectangular column away from the reducer, and a rubber protective sleeve is fitted on the circumferential surface of the rotating column.

[0013] Preferably, the outer surface of the mounting side plate base is provided with a pushing block, and the downward groove facilitates the downward movement of the overall assembly mechanism inside the shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention uses mounting bearing plates to place precast concrete pipe one and precast concrete pipe three on the inner wall of the mounting bearing plates. The positions of precast concrete pipe one and precast concrete pipe three inside the mounting bearing plates are adjusted by the mounting bearing plates. At the same time, the verticality of the vertical ruler is observed. When the bubble inside the vertical ruler is centered, precast concrete pipe one and precast concrete pipe three are on the same horizontal line. At the same time, the mounting side plate base is placed against the inner wall of the shaft, so that the mounting side plate base is vertically set on the inner wall of the shaft. At this time, the degree of compression between the telescopic column and the compression spring is adjusted to correspond to the unevenness of the inner wall of the shaft, so that the mounting bearing plates are vertically aligned with the inside of the shaft.

[0016] 2. The present invention also includes a high-power motor installed at the top of the bearing plate. When the cross-sections of the open ends of the precast concrete pipe 1 and the precast concrete pipe 3 are not aligned, the high-power motor drives the reducer to reduce speed and increase torque. The reducer then drives the rotating column through the transmission rectangular column. The surface of the rotating column is fitted with a rubber protective sleeve. The rotating column drives the precast concrete pipe 1 to rotate, so that the cross-section of the precast concrete pipe 1 is aligned with the precast concrete pipe 3. At the same time, the rubber protective sleeve protects the inner wall of the precast concrete pipe 1 and prevents the rotating column from damaging the inner wall of the precast concrete pipe 1 when it rotates.

The mounting bearing plate 9 has a tile-shaped structure and is located inside the mounting bearing plate 9 during installation of precast concrete pipe 1 and precast concrete pipe 3. A column 10 is fixedly mounted on the surface of the mounting side plate base 4. A support platform 11 is fixedly mounted on one end of the column 10. A hydraulic cylinder 12 is fixedly mounted on the surface of the support platform 11. A push block 14 is fixedly mounted on one end of the telescopic end of the hydraulic cylinder 12. A through groove is opened inside the push block 14 and a transparent glass is installed therein. A vertical ruler 15 is installed inside the push block 14. The surface of the push block 14 away from the hydraulic cylinder 12 is fixedly connected to the surface of the mounting bearing plate 9.

[0026] The upper and lower ends of the mounting side plate base 4 are fixedly equipped with soil-breaking blades 5. One side of the soil-breaking blades 5 is knife-shaped, and the soil-breaking blades 5 are used to break the soil and descend inside the shaft.

[0027] There are four hydraulic cylinders 12. A connecting horizontal plate 13 is fixedly installed on the circumferential surface of the extension and retraction ends of the four hydraulic cylinders 12. The connecting horizontal plate 13 is used to drive the extension and retraction ends of the hydraulic cylinders 12 to move in a unified manner.

[0028] A connecting component 16 is fixedly provided on the circumferential surface of the telescopic column 7. The connecting component 16 includes a vertical plate connecting the column.

[0029] A bracket 17 is fixedly installed at one end of the connecting cylinder of the connecting component 16. A high-power motor 18 is fixedly installed on the inner wall of the bracket 17. An inner horizontal plate 19 is fixedly installed on the inner wall of the mounting bearing plate 9. A circular through groove is opened inside the inner horizontal plate 19, and the output shaft of the high-power motor 18 moves through and extends to the other end of the inner horizontal plate 19.

[0030] A reducer 20 is fixedly installed at one end of the output shaft of the high-power motor 18, and a transmission rectangular column 21 is fixedly installed at one end of the transmission shaft of the reducer 20.

[0031] A rotating column 22 is fixedly installed at the end of the transmission rectangular column 21 away from the reducer 20, and a rubber protective sleeve 23 is fitted on the circumferential surface of the rotating column 22.

[0032] The outer surface of the mounting side plate base 4 is provided with a push block 14, and the downward groove 24 facilitates the downward movement of the overall assembly mechanism inside the well.

[0033] Working principle: During installation;

[0034] S1: Insert the precast concrete pipe 1 and the precast concrete pipe 3 into the inside of the mounting bearing plate 9, and set the overall assembly mechanism inside the shaft. The mounting side plate base 4 rests against the side wall of the shaft, so that the mounting bearing plate 9 stands vertically inside the shaft. By pushing the vertical ruler 15 inside the block 14, observe the air bubbles inside the vertical ruler 15 to adjust the verticality of the mounting bearing plate 9.

[0035] S2: When the mounting bearing plate 9 is adjusted to be perpendicular to the ground plane inside the shaft, the hydraulic cylinder 12 is activated, so that the extension end of the hydraulic cylinder 12 pushes the push block 14 through the connecting horizontal plate 13, so that the push block 14 pushes the mounting bearing plate 9, thereby pushing the mounting bearing plate 9 to the middle position of the precast concrete pipe 1 and the precast concrete pipe 3 in the shaft.

[0036] S3: When precast concrete pipe 1 and precast concrete pipe 3 reach the middle position of the shaft, it is necessary to adjust the degree of fit of the open ends of the contact surfaces of precast concrete pipe 1 and precast concrete pipe 3 to make the open ends of precast concrete pipe 1 and precast concrete pipe 3 aligned flat. At this time, it is necessary to start the high-power motor 18, so that the output shaft of the high-power motor 18 reduces the speed and increases the torque through the reducer 20, thereby driving the transmission rectangular column 21 through the reducer 20. The transmission rectangular column 21 drives the rotating column 22. The rotating column 22 has a rectangular cross-section. Precast concrete pipe 1 is fitted onto the surface of the rotating column 22. A rubber protective sleeve 23 is fitted onto the surface of the rotating column 22, so that the rubber protective sleeve 23 is close to the inner wall of the precast concrete pipe 1. This causes the rotating column 22 to drive the precast concrete pipe 1 to enlarge, so that the cross-section of the open end of the precast concrete pipe 1 is aligned with the cross-section of the precast concrete pipe 3, thereby completing the installation of the entire rainwater pipe.
