Description

Technical Field

[0001] The invention relates to the technical field of concrete construction, in particular to a drip pipe maintenance spraying system for a ship lock foundation pit pier. Background Art

[0002] For a long time, cantilever formwork has been mostly used for pier casting construction. Its working principle is: the bottom of the pier formwork is fixed on the cantilever platform, and the cantilever platform is fixed on the ground or on the outer wall of the next pier that has been cast and has sufficient stress to support the overall cantilever formwork, so as to achieve step-by-step casting of the pier from top to bottom.

[0003] However, the piers need to be cured as they are poured. The existing practice is to insert and extend the drip pipe in sections on the cantilever formwork platform. As the cantilever formwork platform is cast and raised, the drip pipe is manually wound around it, and then a layer of plastic film is manually wrapped around the outer periphery of the drip pipe. Since the drip pipe is connected in sections, it is necessary to manually repeatedly plug and unplug the water supply connection between the first-level drip pipe on the cantilever formwork platform and the water tank, and the winding spacing and winding tension of the drip pipe and the plastic film are controlled by manual experience, resulting in poor consistency and inconsistent maintenance effects. In addition, the labor intensity and experience requirements of the construction personnel are relatively high.

[0004] Therefore, how to design a drip pipe maintenance spray system for the piers of the ship lock foundation pit to realize the automated construction of drip pipe and plastic film winding maintenance as the cantilever formwork platform rises has become a technical problem to be solved urgently by people in this field. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a drip pipe maintenance spraying system for a ship lock foundation pit pier, which can realize the automated construction of drip pipe and plastic film winding maintenance as the cantilever formwork platform rises, and has a simple structure and is easy to implement.

[0006] In order to solve the above problems, the present invention provides a drip pipe maintenance spraying system for the pier of the ship lock foundation pit.

[0007] The drip tube maintenance spray system includes an annular guide rail fixed on the cantilever formwork platform, and front and rear wheelbarrows sliding in the annular guide rail; the front and rear wheelbarrows are provided with a spray pipe winding roller, a water tank and a plastic film winding roller in sequence from the front end in the driving direction to the rear end in the driving direction;

[0008] The spray pipe winding roller is rotatably arranged on the front and rear wheelbarrows, and the spray pipe wound on the spray pipe winding roller is provided with spray holes at intervals; the free end of the spray pipe is blocked and fixedly wound around the outer periphery of the pier, and the middle section of the spray pipe is sealed to penetrate the water tank and immersed below the liquid level in the water tank;

[0009] The plastic film winding roller is rotatably arranged on the front and rear wheelbarrows, and the plastic film with a free end wound around it is tied and fixed on the outer periphery of the pier column;

[0010] An air pump connected to the inside and outside of the water tank is fixed on the water tank. The air pump adjusts the positive and negative pressures and pressure inside the water tank to adjust the water outlet rate from the middle section to the free end of the spray pipe.

[0011] Preferably, the front and rear wheelbarrow comprises a vehicle board, a front wheel and a rear wheel, wherein the front wheel and the rear wheel are both constrained by the side walls of the annular guide rail and are connected to the center line of the bottom surface of the vehicle board through adaptive angle adjustment.

[0014] The advantages of the present invention compared with the prior art are:

[0015] The drip pipe maintenance spray system of the ship lock foundation pit pier of the present invention provides circumferential movement guidance relative to the pier for the front and rear wheelbarrows through the circumferential guide rails arranged on the cantilever formwork platform, and realizes the forward and turning movement of the vehicle plate through the wheel frame under the vehicle plate that can adaptively rotate and support the front single wheel and the rear single wheel. It is not affected by the cross-sectional shape of the pier and the layout shape of the circumferential guide rail, and avoids the problem of structural self-locking of the front and rear wheelbarrows in the circumferential guide rail due to too small a turning angle.

[0016] The present invention provides a drip pipe maintenance spray system for the piers of the ship lock foundation pit.

[0031] The plastic film winding roller is rotatably arranged on the front and rear wheelbarrows, and the plastic film with a free end wound around it is tied and fixed on the outer periphery of the pier column;

[0032] An air pump 8 communicating with the inside and outside of the water tank is fixedly arranged on the water tank, and the air pump adjusts the positive and negative pressures and the pressure inside the water tank to adjust the water outlet rate from the middle section to the free end of the spray pipe.

[0033] Preferably, the front and rear wheelbarrow comprises a vehicle plate 17, a front wheel 16 and a rear wheel 14, wherein the front wheel and the rear wheel are both constrained by the side walls of the annular guide rail and are connected to the center line of the bottom surface of the vehicle plate through adaptive rotation angle adjustment.

[0035] Preferably, a power motor 12 and a battery 11 are fixedly mounted on the wheel frame supporting the rear wheel; the power motor provides rotational power for the rear wheel; and the battery supplies power to the power motor and the air pump.

[0036] In addition, the present invention preferably adopts mature products in the prior art for the power motor and the battery, and the connection structure for the power motor to provide rotational power for the rear unicycle adopts mature technical means in the prior art.

[0037] In addition, the present invention is preferred that, since the front single wheel and the rear single wheel are both rotatably connected to the center line of the bottom surface of the vehicle board, the bottom surface of the vehicle board needs to be slidably overlapped on the top surface of the annular guide rail to maintain the balance of the vehicle board.

[0038] In addition, in the present invention, preferably, the sealing connection method of sliding seals on both sides of the water tank and penetrating and connecting the spray pipe adopts mature technical means in the prior art.

[0039] The working principle of the present invention is:

[0040] The drip pipe maintenance spraying system for the pier column of the ship lock foundation pit of the present invention, when working:

[0041] 1. Manually pull out the ends of the spray pipe and plastic film to fix the ends of the two ends to the outer wall of the pier;

[0042] 2. When the cantilever casting formwork has finished casting a section of pier and is rising, the power motor starts to drive the front and rear wheelbarrows to travel in the circular guide rail. During the driving process, the spray pipe and the plastic film are pulled, driving the spray pipe winding roller and the plastic film winding roller to rotate. According to the driving direction of the front and rear wheelbarrows and the layout position of the spray pipe winding roller and the plastic film winding roller, the spray pipe is wound on the pier, and the spray pipe and the pier are covered with plastic film.

[0043] 3. When adjusting the flow of the sprinkler pipe, the following working conditions are included:

[0044] A. Rapid spraying: The air pump is started to fill the water tank with pressurized air, and the water tank is kept at a positive pressure. The water in the compressed water tank is injected into the spray pipe through the spray hole, and then flows into the spray pipe downstream of the water tank with the water's own weight. Finally, the water is sprayed out from the spray hole of the spray pipe wrapped around the pier downstream to achieve rapid maintenance of the pier. This working condition is suitable for the initial stage of spray maintenance of the pier, or when the temperature of the construction environment is high, or when the pier is high (the cantilever formwork platform is far away from the bottom of the pier, resulting in a long spray pipe).

[0045] B. Slow drip irrigation maintenance: turn off the air pump, and the air enters the water tank from the spray hole upstream of the water tank through the spray pipe. At the same time, the water in the water tank flows from the spray hole to the spray pipe downstream of the water tank to achieve slow long-term maintenance of the pier, avoid frequent water tank refilling, and avoid excessive water spraying leading to water accumulation under the pier, which causes waste of resources;

[0046] C. Stop spraying: Start the air pump to extract the air inside the water tank. At this time, the water tank maintains a negative pressure; the gas enters the water tank through the spray holes upstream and downstream of the water tank and the spray pipe, and is then discharged by the air pump, maintaining a negative pressure in the water tank to prevent water from flowing out through the spray pipe.

[0047] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
