Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses a method for maintaining a high-strength concrete perforated pipe with a vertical structure.
A method for maintaining a high-strength concrete perforated pipe with a vertical structure comprises the following steps:
a. selecting a proper place by a worker, and constructing a maintenance system 1 in the appointed place; after the staff selects a proper place, the broken stones near the place are cleaned, the ground of the place is paved, and then a maintenance room is built on the appointed place. Then, the worker firstly lays the main pipeline 11, then lays the branch pipes 12 and finally lays the maintenance perforated pipes 13.
The worker erects the main pipeline 11 at the top of the maintenance room when laying the branch pipes 12, and notices that the main pipeline 11 should be kept away from the structural frame body of the maintenance room when erecting the main pipeline 11. In 1 use of maintenance system, trunk line 11 can reduce the influence to maintenance room structure support body, even the staff maintains and maintains trunk line 11 in the later stage use, because trunk line 11 has avoided the structure support body in maintenance room, staff maintains or changes trunk line 11, can not produce great influence yet to the major structure in maintenance room.
When the worker lays the branch pipes 12, the branch pipes 12 are fixed on the wall surface or the column inside the maintenance room, cement nails are arranged on the branch pipes 12 every other meter, and the branch pipes 12 are fixed on the wall surface or the column by using the cement nails. The cement nails can increase the stability of the branch pipes 12, and when the maintenance system 1 works, the cement nails can reduce the risk of falling off of the branch pipes 12, thereby reducing the failure rate of the maintenance system 1.
After the branch pipes 12 are arranged, a worker arranges transverse maintenance perforated pipes 13 on the top of a wall or a column along the horizontal direction, a main pipe 11 in the maintenance system 1 is connected with the branch pipes 12, the branch pipes 12 are connected with the maintenance perforated pipes 13, water conveyed by the main pipe 11 is conveyed into each branch pipe 12, the branch pipes 12 convey the water into the maintenance perforated pipes 13, and finally the maintenance perforated pipes 13 uniformly pour the water onto the concrete prefabricated member.
b. The method comprises the following steps that a worker places a poured concrete prefabricated member to a specified position and covers a plastic film on the concrete prefabricated member; the staff wraps up the plastic film along the vertical surface of concrete prefabricated member evenly, makes the concrete prefabricated member be in the state of moisturizing during the maintenance. The plastic film can reduce the water loss on the surface of the concrete prefabricated member and reduce the surface cracking of the concrete prefabricated member caused by water loss, thereby smoothly completing the hydration of the concrete prefabricated member.
c. The worker debugs the water spraying pressure of the maintenance system 1; after the preparation work is finished, recording an initial pressure value to ensure that water flow is continuous and is not sprayed, and adjusting the initial pressure to ensure that the system works stably so that water in the curing perforated pipe 13 can be uniformly poured onto the surface of the concrete prefabricated member.
d. A worker uses the maintenance system 1 to supplement water for the concrete prefabricated part; during the curing, the worker needs to check and maintain the curing system 1 every day, and stops watering and curing when the curing time of the concrete preform exceeds 21 days.
Referring to fig. 1, the maintenance system 1 includes a main pipe 11 and branch pipes 12 fixedly installed at the top of a maintenance room, a maintenance floral pipe 13 fixedly installed on a wall surface or a cylindrical surface of the maintenance room, and a water supply mechanism 14 for supplying water to the main pipe 11. The main pipeline 11 avoids a structural frame body of a maintenance room, the branch pipes 12 are fixed on the wall surface or the cylindrical surface of the maintenance room by using cement nails, and the cement nails are arranged on the branch pipes 12 every other meter. One end of the branch pipe 12 is connected with the water supply mechanism 14, the other end is connected with the branch pipe 12, and the maintenance perforated pipe 13 is connected with the branch pipe 12. The maintenance perforated pipe 13 is fixed on the wall surface or the cylindrical surface at the top of the maintenance room along the horizontal direction by using cement nails.
Referring to fig. 2, the water supply mechanism 14 includes a water supply tank 141, a pressure maintaining pump 142, and a pneumatic pump 143. The main pipeline 11 is connected with the water supply tank 141, two pressure stabilizing pumps 142 are arranged, the pneumatic pump 143 and the pressure stabilizing pump 142 are both installed on the main pipeline 11, the two pressure stabilizing pumps 142 and the pneumatic pump 143 are both arranged in parallel, and the pressure gauge 111 is installed on the main pipeline 11. In practice, the pressure of the water in the main pipe 11 can be obtained by the staff according to the indication on the pressure gauge 111.
The two pressure stabilizing pumps 142 apply certain pressure to the water in the water supply tank 141 to be delivered into the main pipeline 11, and the water cups in the water supply tank 141 are delivered into the main pipeline 11 and then flow into the maintenance perforated pipe 13 through the branch pipe 12. The two pressure stabilizing pumps 142 make the water in the curing perforated pipe 13 flow out at a certain pressure, and the water falls on the surface of the concrete prefabricated member after flowing out of the curing perforated pipe 13, so that the temperature of the concrete prefabricated member is reduced.
The pressure maintaining pump 142 is provided with three working pressure control points (P2, P3, P4) for controlling the operation of the pressure maintaining pump 142. When the pressure stabilizing pump 142 continuously fills water into the pipe network, the pressure in the pipe network rises, and when the pressure reaches a set pressure value P4 (pressure stabilizing upper limit), the pressure stabilizing pump 142 stops working. The pressure of the official network gradually decreases with the water for maintenance, and when the pressure of the official network decreases to a set pressure value P3 (lower pressure stabilizing limit), the pressure stabilizing pump 142 is started again. The process is repeated in cycles, so that the pressure of the official net is always controlled between P3 and P4.
The pneumatic pump 143 is arranged vertically, the top of the pneumatic pump 143 is provided with an air supplement port 1431, and the bottom of the pneumatic pump 143 is provided with a safety valve 1432. In practice, the maintenance pump 142 is frequently started for various reasons, which not only makes the pump vulnerable, but also makes the entire maintenance system 1 disadvantageous. Therefore, the pressure stabilizing pump 142 is often used in combination with a small-sized pneumatic tank, and when a pneumatic tank is used, the adjustment volume is determined by calculation according to the number of times that the pneumatic pump 143 is started is not more than 10 times/H.
Four pressure controls of P1, P2, Ps1 and Ps2 are set in the air pressure tank, P1 is the minimum working pressure of the air pressure tank, the pressure in the main pipeline 11 is reduced along with the outflow of the sprayed water, when the pressure in the pipeline is reduced from Ps2 to Ps1, the pressure stabilizing pump 142 is automatically started to supplement water into the air pressure tank, and the pressure stabilizing pump 142 stops working until the pressure in the tank reaches Ps2, so that the water stored in the air pressure tank is always stored.
After the atmospheric pressure jar worked a period, the staff can be followed the tonifying qi mouth 1431 tonifying qi of atmospheric pressure jar top, and when the pressure in the atmospheric pressure jar was too high, the staff can reduce the pressure in the atmospheric pressure jar through relief valve 1432 to guarantee the security of atmospheric pressure jar.
The implementation principle of the method for maintaining the high-strength concrete perforated pipe with the vertical structure in the embodiment of the application is as follows: during two steady voltage pump 142 carried the main pipeline 11 with certain pressure with the water in the water supply tank 141, water that has certain pressure watered the surface of concrete prefabricated member through branch pipe 12 and maintenance floral tube 13, can take away the heat that the concrete prefabricated member hydration produced on the one hand, reduced concrete prefabricated member's temperature, on the other hand can reduce concrete prefabricated member's moisture loss, reduced concrete prefabricated member fracture's risk.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
