Description

Technical Field

[0001] The utility model relates to the construction of plastic drainage boards in the process of soft soil foundation treatment, in particular to an efficient water injection device for solving the problem of drainage board backhaul, which is applicable to the injection water pressure weighting in the drainage board construction, so as to solve the phenomenon of drainage board backhaul. Background Art

[0002] In the process of soft foundation treatment construction, the construction technology usually adopted is to drive plastic drainage boards for drainage consolidation. The construction quality and efficiency of drainage boards are one of the key indicators for project profitability. During the construction process, limited by the soil conditions within the design depth, the plastic drainage boards are prone to the phenomenon of backhaul. After backhaul, re-driving operations are required, which seriously affects the construction quality and efficiency. Considering that the hydraulic plug-in machine (modified from an excavator) has no 220V voltage and cannot directly control the opening and closing of the water injection pump in the cab, a special person is needed to cooperate with the opening and closing of the water pump, resulting in a waste of human resources. Because the time taken for the plug-in machine to drive a single root is short, the water pump needs to be frequently opened and closed, which is a damage to the water pump itself, and there will be a waiting time after the water pump is restarted for water injection. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide an efficient water injection device for solving the backhaul of drainage boards, which greatly improves the construction efficiency of drainage boards, saves the input of human resources, and reduces the failure rate of frequent opening and closing of the water pump.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is:

[0005] An efficient water injection device for solving the backhaul of drainage boards includes a main water inlet pipe. One end of the main water inlet pipe extends into a water supply pool and is connected to a water supply pump, and the other end of the main water inlet pipe is connected to a tee. The other two interfaces of the tee are respectively connected to a first valve and a second valve; the other end of the first valve is connected to a water injection pipe, and the other end of the water injection pipe extends upward to the top of the insertion rod; the other end of the second valve is connected to a drain pipe; the other end of the drain pipe is communicated with a temporary sump.

[0006] The temporary sump is communicated with the water supply pool through a pipeline and the height of the temporary sump is higher than that of the water supply pool.

[0007] The utility model provides an efficient water injection device for solving the backhaul of drainage boards, which has the following technical effects:

[0008] 1). By adopting the main water inlet pipe, the water injection pipe, the drain pipe, the first valve and the second valve, intermittent water injection into the insertion rod can be realized by controlling the opening and closing of the two groups of valves. Compared with frequently opening and closing the pump body, it is simple and fast, and the service life of the water pump can be extended.

[0009] 2). Since the drain pipe can return the water body to the temporary sump and then back to the water supply pool through the temporary sump, the advantages are as follows: First, it reduces water consumption. The most important point is that it can avoid the random discharge of water in the drain pipe, thus preventing excessive site ponding and having an adverse impact on the installation of drainage plates.

[0010] 3). The application number is "201910369902.5" and the name is "A device for eliminating the backflow of soft foundation drainage plates using high water pressure". This device also uses high-pressure water. Compared with this comparative document, the device of the present application is mainly applied to a hydraulic type drainage plate inserter, with a relatively simpler structure and being convenient and fast to fabricate on-site. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0012] Figure 1 It is a structural schematic diagram of the present utility model.

[0013] In the figure: water inlet main pipe 1, tee 2, water injection pipe 3, drain pipe 4, first valve 5, second valve 6, insertion rod 7, support 8. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] As Figure 1 shown, an efficient water injection device for solving the backflow of drainage plates includes a water inlet main pipe 1. The water inlet main pipe 1 is made of PP-R material. One end of the water inlet main pipe 1 extends deep into the water supply pool and is connected to a water supply pump. The other end of the water inlet main pipe 1 is connected to a tee 2. The other two interfaces of the tee 2 are respectively connected to a first valve 5 and a second valve 6 by hot melting. The other end of the first valve 5 is connected to a water injection pipe 3. The other end of the water injection pipe 3 extends upward to the top of the insertion rod 7 (there is a certain interval between the water injection pipe 3 and the insertion rod 7 to prevent the insertion rod 7 from colliding with the water injection pipe 3 when the insertion rod 7 moves up and down. When the insertion rod 7 is inserted to the appropriate position, the water in the water injection pipe 3 sprays out and just enters the insertion rod 7). The other end of the second valve 6 is connected to a drain pipe 4. The other end of the drain pipe 4 communicates with a temporary sump, and the water in the temporary sump finally flows into the water supply pool.

[0015] The first valve 5 and the second valve 6 can adopt common water supply valves on the market.

[0016] Here, the support 8 (insertion rod driving structure) converts the hydraulic pressure of the excavator into the power source for the up and down movement of the insertion rod and does not move up and down with the insertion rod 7. The water injection pipeline can be suspended and fixed on the insertion rod driving structure through a rope.

[0017] Working principle and process:

[0018] 1). After the insertion rod 7 of the drainage plate inserter is inserted to the designed depth, turn on the water supply pump (it does not need to be turned off during the working day after being turned on).

[0019] 2), Open the first valve 5 and close the second valve 6, and water flows into the inserting rod 7 of the inserting machine.

[0020] 3), When the water in the inserting rod 7 is filled to an appropriate amount, first open the second valve 6, and then simultaneously close the first valve 5, and the inserting rod 7 can be lifted. The water flow will flow into the temporary sump along the drain pipe 4 and finally into the water supply pool.

[0021] 4), Repeat the above operations to achieve efficient water injection, improve construction efficiency and save human resources at the same time.
