Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a dewatering construction device and its construction method. Background Technology

[0002] As people's lives develop faster and faster, there are more and more construction projects, and these projects are often accompanied by dewatering.

[0003] Vacuum lightweight wellpoint dewatering is a commonly used method for dewatering construction. It is effective, low-cost, and has good dewatering results. However, this method is currently only suitable for dewatering sandy soils. For soils with multiple water layers or impermeable layers, the pumping pipes will eventually stop contacting the water surface as dewatering progresses, resulting in poor dewatering effects.

[0004] Regarding the aforementioned technologies, the inventors believe that vacuum lightweight wellpoint dewatering is not suitable for dewatering multiple water layers and has the drawback of poor dewatering effect. Summary of the Invention

[0005] In order to improve the effect of precipitation, this application provides a precipitation construction device and its construction method.

[0006] Firstly, this application provides a dewatering construction device, which adopts the following technical solution:

[0007] A dewatering construction device includes a casing, a secondary pipe, and multiple rubber pistons. The secondary pipe is placed inside the casing, and the secondary pipe and the casing are in the same length direction and are slidably connected. The rubber piston is fixed on the outer wall of the secondary pipe and abuts against the inner wall of the casing. The rubber piston and the casing are slidably connected. Both ends of the secondary pipe are open along its length direction. The casing has filter holes. A vacuum pump is installed at one end of the secondary pipe outside the soil layer.

[0008] By adopting the above technical solution, when precipitation is required, the casing is inserted into the soil layer, and water enters through the filter hole and then into the secondary pipe. The vacuum pump is started to extract the water. During the pumping process, the water level will drop. When the secondary pipe is removed from the water surface, the atmospheric pressure will push the rubber stopper, pushing the secondary pipe to contact the water surface and continuing precipitation. There will be no interruption in precipitation until the precipitation reaches the required construction height, at which point the vacuum pump is stopped, thus improving the precipitation effect.

[0009] Optionally, multiple filter holes are provided, and the multiple filter holes are arranged along the length of the sleeve.

[0010] By adopting the above technical solution, the filter holes are set along the length of the sleeve, thereby ensuring that the water level is lowered. Water can enter from the lower filter holes, which is conducive to the normal precipitation process and achieves the effect of improving precipitation.

[0011] Optionally, a T-connector is installed at one end of the secondary tube housing the vacuum pump, and a main pipe is provided on multiple T-connectors. The main pipe passes through multiple T-connectors simultaneously, and the main pipe, T-connectors, and secondary tube are all interconnected.

[0012] By adopting the above technical solution, the setting of the tee connector and the main pipe, all the secondary pipes are connected together, and water pumping can be completed with a single vacuum pump, avoiding the need to use a large number of vacuum pumps and achieving a convenient and quick result.

[0013] Optionally, a flexible hose is provided between the tee connector and the secondary pipe. One end of the flexible hose is fixedly connected to the secondary pipe, and the other end of the flexible hose is fixedly connected to the tee connector. The flexible hose, the secondary pipe, and the tee connector are all connected.

[0014] By adopting the above technical solution, the hose is installed to connect the secondary pipe and the tee connector. During the precipitation process, the position of the secondary pipe will slide, and the hose facilitates the sliding of the secondary pipe, thereby achieving the effect of connecting the secondary pipe and the tee connector.

[0015] Optionally, two clamping plates are slidably disposed on the tee connector. When the dewatering construction device is used, both clamping plates are tightly abutted against the corresponding sleeves, and the sleeves are placed between the two clamping plates.

[0016] By adopting the above technical solution, the clamping plate is set and clamped on the sleeve, thereby fixing the tee connector and thus fixing the main pipe, achieving the effect of fixing the main pipe.

[0017] Optionally, the two clamping plates are provided with threaded rods that pass through both clamping plates simultaneously. The threaded rods and the two clamping plates are threadedly connected, and the threads at both ends of the threaded rods have opposite directions of rotation.

[0018] By adopting the above technical solution, when it is necessary to fix the main pipe, the sleeve is placed between the two corresponding clamping plates, the threaded rod is rotated, the two clamping plates move closer to each other until the two clamping plates and the sleeve are tightly abutted, the tee connector is fixed, thereby fixing the main pipe and achieving the effect of fixing the main pipe.

[0019] Optionally, a connecting block is fixed on the tee connector, and a connecting rod is provided on multiple connecting blocks. The connecting rod passes through multiple connecting blocks simultaneously, and the connecting rod and multiple connecting blocks are slidably connected.

[0020] By adopting the above technical solution and setting the connecting rod, multiple connecting blocks are connected together and fixed to the tee connector, thereby making the connection between multiple tee connectors more secure and achieving the effect of increasing the connection stability between multiple tee connectors.

[0021] Optionally, a reinforcing block is slidably provided on the connecting block, and a fixing groove is provided on the sleeve. When the dewatering construction device is used, and the two clamping plates clamp the sleeve, the reinforcing block is partially embedded in the fixing groove. At this time, the connecting rod and multiple reinforcing blocks are tightly abutted together.

[0022] By adopting the above technical solution, the reinforcing block is embedded in the fixing groove, the reinforcing block and the connecting block are connected, and the connecting block is fixed on the tee connector, thereby making the connection between the tee connector and the sleeve more secure. While the connecting rod connects multiple tee connectors, it pushes out the reinforcing block and embeds it in the fixing groove, making the connection between the tee connector and the sleeve more secure, thereby increasing the connection stability between the tee connector and the sleeve.

[0023] Optionally, a spring is provided inside the connecting block. One end of the spring is fixedly connected to the connecting block, and the other end of the spring is fixedly connected to the reinforcing block. When the connecting rod and the reinforcing block are in close contact, the spring is in a stretched state. When the connecting rod is detached from the connecting block, the spring is in a natural state, and the reinforcing block is completely detached from the fixing groove.

[0024] By adopting the above technical solution, when it is necessary to fix the tee connector to the sleeve, or when it is necessary to remove the tee connector from the sleeve, the connecting rod is slid out and detached from the entire tee connector. Under the action of the spring, the reinforcing block is pulled back into the connecting block, preventing the reinforcing block from sliding again, thus achieving a convenient and quick effect.

[0025] Secondly, this application provides a construction method for a precipitation construction device, which adopts the following technical solution:

[0026] A construction method for a precipitation control device includes the following steps:

[0027] S1. Insert the casing into the soil layer and align the tee connector with the casing;

[0028] S2. Tighten the threaded rod until the two clamping plates clamp the sleeve tightly;

[0029] S3. Pass the connecting rod through multiple connecting blocks simultaneously;

[0030] S4. Connect the vacuum pump to the main pipe and start the vacuum pump to reduce water level.

[0031] By adopting the above technical solution, when precipitation is required, the secondary pipe will slide, so that one end of the secondary pipe opening is always placed in the water, thus ensuring that precipitation is not interrupted and improving the precipitation effect.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The installation of casing, secondary pipe, rubber piston, and filter holes improves the precipitation effect;

[0034] 2. The design of the tee connector, main pipe, and spring achieves a convenient and quick connection.

[0035] 3. The flexible hose is designed to connect the secondary pipe and the tee connector;

[0042] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0043] This application discloses a precipitation construction device.

[0045] Reference Figure 1Multiple sleeves 1, secondary tubes 2, and rubber pistons 3 are provided, and each sleeve 1, secondary tube 2, and rubber piston 3 corresponds to the other. The length direction of the sleeve 1 is perpendicular to the ground. The sleeve 1 is inserted into the soil layer. Multiple filter holes 4 are opened on the side wall of the sleeve 1. The multiple filter holes 4 are equally spaced along the length direction of the sleeve 1. The length direction of the line connecting the centers of the multiple filter holes 4 is the same as the length direction of the sleeve 1. The length direction of the secondary tube 2 is the same as the length direction of the sleeve 1. The secondary tube 2 is provided with a scale. The secondary tube 2 is embedded in the sleeve 1 and slides in the sleeve 1. The sliding direction is set along the length direction of the sleeve 1. Both ends of the secondary tube 2 are open along the length direction.

[0046] The rubber piston 3 is fixed to the secondary pipe 2 with a ring. The rubber piston 3 and the inner wall of the sleeve 1 are completely in contact. The rubber piston 3 seals the gap between the sleeve 1 and the secondary pipe 2. The rubber piston 3 and the sleeve 1 are slidably connected, and the sliding direction is set along the length of the sleeve 1. When precipitation is required, the sleeve 1 is inserted into the soil layer, the vacuum pump is connected to the secondary pipe 2, the vacuum pump is started, and water enters from the filter hole 4 and then enters the secondary pipe 2, and is discharged. During the precipitation process, the water level drops. When the secondary pipe 2 is not in contact with the water surface, the rubber piston 3 is pushed by the atmospheric pressure, which pushes the secondary pipe 2 until the secondary pipe 2 is embedded in the water, and precipitation continues. The scale change of the sleeve 1 can be observed to determine whether the precipitation has reached the construction requirements. When the precipitation has reached the construction requirements, the vacuum pump is turned off and the precipitation is stopped.

The main pipe 22 passes through multiple three-way connectors 21 at the same time. The main pipe 22, the three-way connectors 21 and the secondary pipe 2 are all connected. A vacuum pump is installed at one end of the main pipe 22. When dewatering is required, the vacuum pump is started and the vacuum pump can pump water from multiple secondary pipes 2 at the same time.

The connecting block 5 is a rectangular block. A connecting rod 6 is provided on multiple connecting blocks 5.

[0049] A spring 9 is installed inside the connecting block 5. The length direction of the spring 9 is perpendicular to the length direction of the connecting rod 6. One end of the spring 9 is fixedly connected to the bottom of the connecting block 5, and the other end of the spring 9 is fixed to a reinforcing block 7. The length direction of the reinforcing block 7 is the same as that of the spring 9. The reinforcing block 7 and the connecting block 5 are slidably connected, and the sliding direction is set along the length direction of the spring 9. A fixing groove 8 is opened on the outer wall of the sleeve 1, and the reinforcing block 7 is embedded in the fixing groove 8. When the dewatering construction device is needed, the connecting rod 6 passes through multiple connecting blocks 5 at the same time. The end of the connecting rod 6, the reinforcing block 7, and the spring 9 are tightly connected. At this time, the spring 9 is in a stretched state, and the end of the reinforcing block 7 away from the spring 9 is embedded in the fixing groove 8. When the dewatering construction device is not used, the connecting rod 6 is pulled out, and the connecting rod 6 is completely separated from multiple connecting blocks 5. The spring 9 returns to its natural state, and the reinforcing block 7 is completely placed inside the connecting block 5. One end of the connecting rod 6 is conical.

The two clamping plates 24 are arranged opposite each other, and the connecting block 5 is placed between the two clamping plates 24. Both clamping plates 24 are perpendicular to the connecting rod 6. The two clamping plates 24 and the tee connector 21 are slidably connected. The sliding direction is set along the length direction of the connecting rod 6. The sleeve 1 is placed between the two clamping plates 24. Threaded rods 25 are provided on the two clamping plates 24. The threaded rods 25 pass through the two clamping plates 24. The threaded rods 25 and the two clamping plates 24 are threadedly connected. The threads at both ends of the threaded rod 25 have opposite directions of rotation. When the device is used for dewatering, the threaded rods 25 are rotated, and the two clamping plates 24 move closer to each other, clamping the sleeve 1.
