TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete construction, in particular to a drip pipe maintenance spraying system for a lock foundation pit pier column. BACKGROUND

[0002] For a long time, the pier column pouring construction is mostly carried out by using a cantilever formwork. The working principle is that the bottom of the pier column formwork is fixed on the cantilever platform, and the cantilever platform is fixed on the ground or the outer wall of the lower stage pier column which has been poured and completed and has enough stress to support the whole cantilever formwork, so as to realize the step-by-step pouring of the pier column from top to bottom.

[0003] However, the pier column needs to be poured and maintained at the same time. The existing method is to segmentally insert and connect the drip pipe on the cantilever formwork platform, manually wind the drip pipe as the cantilever formwork platform rises, and then manually wrap a layer of plastic film outside the drip pipe. Since the drip pipe is connected in segments, the manual connection between the first stage drip pipe on the cantilever formwork platform and the water tank needs to be repeatedly inserted and pulled, and the winding spacing and tension of the drip pipe and the plastic film are controlled by manual experience, which leads to poor consistency and different maintenance effects, and the labor intensity and experience requirements of the construction personnel are high.

[0004] Therefore, how to design a drip pipe maintenance spraying system for a lock foundation pit pier column to realize the automatic construction of the drip pipe and plastic film winding maintenance as the cantilever formwork platform rises has become a technical problem to be solved by the personnel in the field. SUMMARY

[0009] The plastic film winding roller is rotatably arranged on the front and rear single-wheel trolleys, and the plastic film wound on the plastic film winding roller has a free end bound and fixed to the outer periphery of the pier column.

[0010] The water tank is fixedly provided with an air pump communicating between the inside and outside of the water tank, and the air pump adjusts the positive and negative pressures and the pressure intensity in the water tank to adjust the water outlet rate of the middle section to the free end of the spray pipe.

[0011] Preferably, the front and rear single-wheel trolleys comprise a trolley plate, a front single wheel and a rear single wheel, and the front and rear single wheels are both constrained by the circumferential guide rail side wall and connected to the middle line of the bottom surface of the trolley plate with corner self-adaptive adjustment.

[0040] The working principle of the present application is as follows:

[0041] 1. First, manually pull the spray pipe and the plastic film end to fix the end of the spray pipe and the plastic film to the outer wall of the pier column;

[0042] 2. When the cantilever pouring formwork pours a section of the pier column and rises, the power motor is started to drive the front and rear single wheel plate vehicles to travel in the ring-shaped guide rail.

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

[0044] A. Fast spraying: the air pump is started to fill the water tank with pressurized air, at this time the water tank maintains positive pressure; the compressed water in the water tank is injected into the spray pipe through the spray hole, and then flows into the spray pipe downstream of the water tank, and finally the water is sprayed out of the spray hole of the spray pipe wound on the pier column, to realize the rapid maintenance of the pier column.

[0045] B. Slow drip irrigation maintenance: the air pump is closed, the air enters the water tank through the spray hole from the upstream of the spray pipe, and at the same time, the water in the water tank flows into the spray pipe downstream of the water tank through the spray hole, to realize the slow and long-term maintenance of the pier column, to avoid frequent water replenishment of the water tank, and to avoid water spraying too much to cause water accumulation under the pier column, resulting in resource waste.

[0046] C. Stop spraying: air pump starts, and the air inside the water tank is pumped out, at this time, the water tank maintains negative pressure; the gas enters the water tank through the spraying pipe via the spraying holes on the upstream and downstream of the water tank, and is then discharged by the air pump, so as to maintain the negative pressure in the water tank to avoid the water flowing out of the spraying pipe.
