Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in the figure, the working principle of the high-efficiency dust-settling maintenance system special for the large-area yard behind the wharf is as follows:

through planning, a deep well 1 (pipe well) is drilled in a proper area, a QJ type submersible electric pump for the well is arranged in the pipe well, the electric pump is a water pumping machine with a motor and a water pump which are directly connected into a whole and submerged into water to work, and the electric pump is suitable for extracting underground water from the deep well. The water delivery pipe end of the water pump is connected with a main pipe (PE pipe) with the diameter of phi 40-50, a pressure gauge is installed on the main pipe, the upper and lower limit values of the pressure of the water supply end are set, and related information is transmitted to a control cabinet through a sensor to automatically control the water pumping work of the water pump.

A horizontal branch pipe (pipeline) is arranged at the other end of the pressure gauge through a tee joint or a four-way joint and is placed on a through-length structure such as a structure, a water outlet faucet is arranged on the horizontal pipeline at intervals of 50m, a water outlet switch is arranged beside the water outlet faucet, and water hoses with pressurizing gun heads and different diameters are prepared to be connected with the water outlet faucet through a variable joint and can be taken out for use at any time.

The installation process comprises the following steps: take the XX region of the Taicang XX quan Tao pile engineering as an example

1. A deep well 1 with the diameter of 30cm is arranged in the middle of one side of a C2 structure in the XX area, the well depth is determined according to the underground water level, and enough water quantity is ensured. And then placing a PVC pipe with the diameter of 16cm to protect the well wall so as to prevent the deep hole from collapsing, wherein before the PVC pipe is placed, the hole is poked on the surface of the PVC pipe and the PVC pipe is wrapped by geotextile so as to ensure that the effect of reverse filtration is achieved while the underground water permeates into the pipe well. Considering that the underground soil layer has soft soil layers such as silt, sand and stones are backfilled in the holes to serve as a reverse filtering layer after the pipes are inserted, and the holes in the PVC pipelines are prevented from being blocked. One well of the engineering supplies dust fall and maintenance in four track beam areas.

2. After the pipe well is arranged, a 150QJ10-100 submersible pump 5 is arranged in the well. The motor power is 5.5KW, and the lift is 87-118 m; the PE main pipe 2 with the diameter phi of 40mm is externally connected, the main pipe 2 is connected with the branch pipe 3 in the structure groove 10, a water outlet faucet 9 is arranged on the branch pipe 3 at an interval of 50m, and a water outlet switch is arranged on the water outlet faucet 9;

3. install a manometer 6 at the main pipe end, according to on-the-spot actual conditions, through calculation and field test, confirm the regional required water consumption of watering and water pressure that supply, through setting up the water pressure of this horizontal pipeline pipe network of manometer control on the water pump outlet end pipeline, then through the start-up and closing of sensor 7 automatic control electronic box switch board 8 of setting on the manometer, as long as the play water tap 9 of this water supply network certain position begins to drain, the water pressure in the pipe network will reduce, the pointer of manometer will rotate, when reaching the setting lower limit value, pass to electronic box switch board 8 through sensor 7, the switch board starts the power supply water pump automatically and begins to draw water and keep the water pressure in the pipe network, stop supplying water after reaching the setting pressure upper limit value, prevent the explosion.
