Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete pipe piles, in particular to a prestressed high-strength concrete pipe pile hole plugging device. Background Art
[0002] Prestressed high-strength concrete pipe piles are made of hollow cylindrical concrete prefabricated components by prestressed centrifugal forming technology and steam curing at 10 atmospheres and about 180°C. Prestressed high-strength concrete pipe piles are widely used in engineering project construction due to their many advantages such as fast construction speed, short construction period, small impact on the surrounding environment, and green environmental protection.
[0003] The hole diameter of the prestressed high-strength concrete pipe pile is large. During large-scale construction, due to the different depths of pile delivery, dense pile hole groups are formed on the construction site, which not only brings significant safety hazards and increases the difficulty of on-site safety management, but also the ground soil is easily collapsed after being disturbed during the excavation process or after the pile is delivered, and the soil falls into the core of the prestressed concrete pipe pile, causing the pile core to be blocked. Before the subsequent construction of the pile cap foundation, the pile core soil must be cleaned before the steel cage can be placed in the pile core and concrete can be poured. This leads to slow progress and increased construction costs. Utility Model Content

[0034] Reference Figure 1-6 A prestressed high-strength concrete pipe pile hole sealing device is used to prevent the prestressed high-strength concrete pipe pile hole from being blocked during construction in order to prevent construction workers and earth from falling into the pipe pile.
[0035] The prestressed high-strength concrete pipe pile hole plugging device comprises two cover plates 1, an air bag 2 and a connecting piece 5;
[0036] A fixing ring 10 is fixedly connected to the bottom of the two cover plates 1, and a flexible rope 9 is fixedly connected to the top of the airbag 2. The top of the flexible rope 9 is fixedly connected to the fixing ring 10. The two cover plates 1 can be connected and fixed to the airbag 2 through the flexible rope 9. The airbag 2 is connected to the air nozzle 4 through the connecting tube 11. A fixing hole is opened on one of the cover plates 1, and the air nozzle 4 is fixedly connected to the fixing hole. The airbag 2 can be inflated through the air nozzle 4, so that the airbag 2 expands in the pipe pile hole, so that the outer wall of the airbag 2 is against the inner wall of the pipe pile hole, so that the airbag 2 is fixed in the pipe pile hole. Since the inflated airbag 2 is fixed in the pipe pile hole, the two cover plates 1 can be covered and fixed on the top of the pipe pile hole to block the pipe pile hole and prevent construction personnel and earth from falling into the pipe pile.
[0037] In order to strengthen the stability of the airbag 2 fixed inside the hole of the pile;
[0038] The airbag 2 includes two semicircular parts and a straight section 201. The straight section 201 is arranged between the two semicircular parts. The outer wall of the straight section 201 is provided with multiple layers of reinforcement parts in the vertical direction. Each layer of reinforcement parts includes multiple reinforced airbags 3. Each reinforced airbag 3 is in the form of a horizontal strip and is arranged at intervals around the straight section 201. Each reinforced airbag 3 is connected to the airbag 2 through a vent 202. When the airbag 2 is inflated, the gas enters each reinforced airbag 3 through the vent 202, thereby expanding it. 201 are arranged at intervals to ensure that each reinforced airbag 3 is in contact with the inner wall of the pipe pile hole, so that the airbag 2 can be lifted and fixed in the pipe pile hole. The reinforced airbags 3 of two adjacent layers are staggered. The staggered reinforced airbags 3 are convenient for the air inside the bottom pipe pile to be discharged when the airbag 2 is inflated. The outer side of each reinforced airbag 3 is arc-shaped and the outer wall is provided with a rubber layer 301, which can protect the reinforced airbag 3. The rubber layer 301 is in contact with the inner wall of the pipe pile hole to avoid damage and scratches caused by contact between the reinforced airbag 3 and the inner wall of the pipe pile hole.
[0039] In order to facilitate the folding and unfolding of the device;
[0040] The edges of the two cover plates 1 are provided with downward bending portions, and the two cover plates 1 are rotatably connected by a connecting member 5. The connecting member 5 includes two rotating shafts and a connecting plate. The two rotating shafts are respectively arranged at the two end portions of the connecting plate, and the two rotating shafts are respectively rotatably connected to the bending portions of the two cover plates 1, so that the two cover plates 1 are rotated and folded, and at this time, the bending portions of the two cover plates 1 are fitted together, thereby forming a storage space between the two cover plates 1, and the uninflated airbag 2 can be placed inside the storage space for storage and protection to prevent the airbag 2 from being damaged or scratched.
[0041] The bottom of one of the cover plates 1 is rotatably connected to one side of the other cover plate 1. After the two cover plates 1 are folded, they can be rotated by the fixing member 6 so that one end of the fixing member 6 abuts against the other cover plate 1. At this time, the two cover plates 1 cannot be rotated, so that the folded cover plates 1 are fixed, which is convenient for transporting the folded device. An arc portion 602 is provided at one end of the fixing member 6, which facilitates the fixing member 6 to rotate to a vertical position with the two cover plates 1 through the arc portion 602, and makes one end abut against the cover plates 1. A fixing block 7 is fixedly connected to one side of the bottoms of the two cover plates 1 that are close to each other. Handles 8 are provided on the two fixing blocks 7. After the two cover plates 1 are folded, the device can be carried by the handles 8.
[0042] The working principle of the prestressed high-strength concrete pipe pile hole plugging device is as follows: when in use, the two folded cover plates 1 are rotated and unfolded to be horizontal, and then covered on the top of the pipe pile hole, and then the air bag 2 is inflated through the air nozzle 4, so that the air bag 2 expands in the pipe pile hole, so that the outer wall of the air bag 2 is against the inner wall of the pipe pile hole, and because the gas enters each reinforcement air bag 3 through the air vent 202, each reinforcement air bag 3 is expanded, so that the reinforcement air bag 3 in the form of a horizontal strip contacts the inner wall of the pipe pile hole, ensuring that the air bag 2 is firmly fixed in the pipe pile hole. At this time, the two cover plates 1 fixed to the air bag 2 will cover and be fixed on the top of the pipe pile hole, shielding the pipe pile hole to prevent construction personnel and earth from falling into the pipe pile;
[0043] When the device needs to be taken out from the hole of the pipe pile, the gas in the airbag 2 is first released through the air nozzle 4. At this time, the airbag 2 shrinks and the airbag 2 can be taken out from the hole of the pipe pile. Then, the two cover plates 1 are rotated to fold them tightly together. At this time, the bent parts of the two cover plates 1 fit each other, thereby forming a storage space between the two cover plates 1. The uninflated airbag 2 can be placed inside the storage space for storage and protection to prevent the airbag 2 from being damaged or scratched. Then, the fixing piece 6 is rotated so that one end of the fixing piece 6 is against the other cover plate 1. At this time, the two cover plates 1 cannot be rotated, so that the folded cover plates 1 are fixed, and finally the device is carried by the handle 8.
[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
