Description

Sand bank push down filter water pipe water method

The invention relates to a water-receiving method for pushing a filter water pipe under a sand bank, which is particularly characterized in that a pipe head having a function of pumping and discharging sand is combined with a water filter pipe with a water filter (in which a steel inner pipe is used for waterproofing), and then is drawn. The way of pushing the pipe is to import the inner and outer pipes, and at the same time, the water-proof hair on the wall of the well (also used as the collecting well) is pushed into the sand bank one by one. After the pipe-making operation is completed, the steel pipe (including piping and other equipment) of the mechanical equipment and the water filter pipe of the first section of the pipe is pulled out by the outer pipe, and the pipe head filter material is installed in the outer pipe of the first pipe of the pipe. Construction of the filter water pipe under the sand bank. After the completion of several water filtration pipes in the well as the collection wells, after installing the relevant pumping and control equipment inside and outside the collection wells, the system for taking water from the filter water pipes under the sand bank is completed.

The traditional method of taking sand from the shore is usually to take water from the vertical drilling of the sand bank, to dig the trench at the shore, to take water from the horizontal pipe, or to draw water from the collecting well. Because the above-mentioned construction methods are often limited by the depth of the water intake layer, the thickness of the water layer, the depth of the water trenching, the diameter of the horizontal pipe, the large length of the sand layer resistance, and the water seepage of the filter pipe, the amount of water is not large. Or even impossible to construct.

The traditional method of taking water from the sand bank is usually a vertical method of drilling sand on the sand bank, digging a horizontal pipe at the shore, or installing a horizontal pipe from a collecting well. Vertical drilling and water intake on the sand bank is limited by the depth of the taken water layer, the thickness of the water layer and the range of water collection due to the slow filling of the free water cone surface of the groundwater. The bank digging trenches and burying horizontal pipes to take water, because the trenches are easy to collapse at the waterside, the shallow buried pipes can only be buried in a shallow depth of cover, which is vulnerable to wind and waves and damages the water intake pipeline.

In the traditional way, the horizontal pipe is used to collect water from the collecting well. Because the horizontal filtering water pipe is installed in the sand layer, the sand layer is more difficult to push the water pipe due to the vibration, and the water is difficult to stop when the pipe is filled with water. It is impossible to construct.

The invention relates to a water-removing method for pushing a water filter pipe under a sand bank, which can push the water filter pipe laterally to the inner pipe of the water pipe outside the water edge according to the required diameter, depth and length, and utilize the underwater sand layer to be rich in water. The replenishing ability, in conjunction with the collection wells and related pumping and control equipment, to complete the system of water collection by the filter water pipe under the sand bank to solve the above problems.

The solution is as shown in Fig. 7F, in which the first section (1) of the pipe with the function of pumping sand is combined with the water filter pipe (2) with the water filter (22), wherein the steel inner pipe (6) is used for waterproofing. Then, the inner and outer tubes are simultaneously pushed into the sand bank by the inlet assembly (39) which can be waterproofed by the hair feeding tube (3 as a collecting well). After the pipe-making operation is completed, the mechanical equipment of the first section of the pipe and the steel inner pipe of the water filter pipe (6 pipes and other equipment) are pulled out from the outer pipe, and the pipe head filter material is installed in the pipe outside the first pipe section ( 19), the construction of the filter water pipe under the sand bank is completed. Then, after completing the advancement of several water filter pipes in the water collecting well, and then cooperating with the relevant pumping and control equipment inside and outside the collecting well, the system for taking water from the filter water pipe under the sand bank is completed.

The method of the invention uses the water filter tube (2) with the water filter (22) as an outer tube for the function of collecting water in a relatively deep sand layer under water; and the steel inner tube (6) is mainly used for limiting The water seepage of the outer pipe of the water filter stays between the inner and outer pipes, which prevents the water seepage of the outer pipe from flowing into the well through the inlet when the pipe is pushed; and the water inlet assembly (39) is combined with the water gate (39a) ), the water stop brush (39c2) and the hydraulic water stop ring (39c1), so that the water outside the pipe wall of the filter water pipe (2) when the pipe is pushed is restricted from flowing into the well in the hair inlet assembly (39) ( 3) Inside, the pipe of the water filter pipe can be successfully and successfully.

Claims (1)

A water-removing method for pushing a filter water pipe laterally under a sand bank, characterized in that: a pipe first section (1) having a pumping and discharging function, and a water-permeable filter water pipe (2) having a water filter (22) in a steel The pipe (6) is combined (using the steel inner pipe to prevent the water seepage of the outer pipe), and then the inner and outer pipes are simultaneously sent into the well wall by means of pumping the sand, and the inlet oil pressure is stopped. Cheng (39c) can be used to stop the water in the inlet assembly (39), and push into the sand layer through the well wall one by one. After the pipe pushing operation is completed, the mechanical equipment of the first section of the pipe and the steel inner pipe of the filter pipe ( After the pipe is pulled out by the outer pipe, the pipe head filter material (19) is installed in the outer pipe of the first pipe section, and the special construction method of the pipe water pipe under the sand bank is completed.
