Abstract
Description
Technical Field
[0001] This utility model relates to the field of foundation pit construction technology, and more specifically, to a deep foundation pit drainage device. Background Technology
[0002] Deep foundation pits refer to projects with an excavation depth exceeding 5 meters, or projects with particularly complex geological conditions, surrounding environment, and underground pipelines even if the depth does not exceed 5 meters. Drainage of deep foundation pits is a crucial step in ensuring construction safety and quality. Excessive water accumulation at the bottom of the pit necessitates drainage to lower the water level and ensure smooth excavation; otherwise, prolonged water accumulation can lead to pit collapse.
[0003] Currently, when draining water from deep foundation pits, water pumps are usually installed outside the pit, with pumping pipes extended into the pit to extract and discharge the water outside. However, when the water level in the pit drops to near ground level, water that is too shallow cannot be pumped out. Workers need to sweep the water and use a bucket to collect and scoop it up, which is a cumbersome and inefficient operation. Utility Model Content
[0004] The purpose of this utility model is to provide a deep foundation pit drainage device that can first suck up the accumulated water and then discharge it into the collection tank when the water level in the foundation pit drops to near the ground, which facilitates the operation process and improves efficiency.
[0005] This utility model is achieved through the following technical solution: a deep foundation pit drainage device, comprising: a vehicle body, with rollers at the bottom of the vehicle body and a placement groove on the vehicle body, wherein a water collection tank is placed in the placement groove; a water-absorbing sponge sheet, which can absorb accumulated water on the ground of the deep foundation pit when it slides outside the vehicle body, and can carry the accumulated water into the water collection tank when it moves into the water collection tank; a traction mechanism, which is located at the end of the vehicle body away from the water-absorbing sponge sheet and can drive the water-absorbing sponge sheet to move from outside the vehicle body into the water collection tank; and a squeezing mechanism, which is located in the water collection tank and can squeeze the accumulated water absorbed by the water-absorbing sponge sheet into the water collection tank.
[0006] Furthermore, the traction mechanism includes a drive motor, a drive shaft, and a drive belt. Two support seats are provided on the vehicle body. The drive shaft is rotatably connected between the two support seats. The drive motor is fixedly mounted on one of the support seats and can drive the drive shaft to rotate. The drive belt is wound around the drive shaft, and one end of the drive belt away from the drive shaft is fixedly connected to the water-absorbing sponge sheet.
[0007] Furthermore, the extrusion mechanism includes two vertical seats, with a fixed roller and a pressure roller disposed between the two vertical seats. The vertical seats are provided with elastic pulling members for driving the pressure roller to move closer to the fixed roller. The drive belt can pull the water-absorbing sponge sheet to the gap position between the fixed roller and the pressure roller and cause the water-absorbing sponge sheet to squeeze out the absorbed water.
[0008] Furthermore, the elastic tension member includes a fixed seat, which is fixedly mounted on a vertical seat. A tension rod is slidably mounted inside the fixed seat. The top end of the tension rod is fixedly connected to a pressure roller. A connecting piece is mounted on the tension rod, and a tension spring is connected between the connecting piece and the fixed seat.
[0009] Furthermore, the water collection tank is equipped with a release element for driving the pull rod upward to move the pressure roller away from the fixed roller.
[0010] Furthermore, the release component includes a mounting base, a release electric cylinder, and a release block. The mounting base is fixedly installed on the side wall of the water collection tank. The cylinder barrel of the release electric cylinder is fixedly installed on the mounting base. The release block is fixedly connected to the piston rod of the release electric cylinder. The release block is provided with an arc-shaped surface that can abut against the pulling rod and drive the pulling rod to move upward.
[0011] Furthermore, the bottom wall of the water collection tank is inclined, and the side of the water collection tank closer to the traction mechanism is lower than the side of the water collection tank farther away from the traction mechanism.
[0012] Furthermore, it also includes a water pumping mechanism, which includes a water pump and a water pumping pipe. The water pump is located outside the deep foundation pit. One end of the water pumping pipe is connected to the water pump, and the other end extends into the water collection tank and is located at the lowest end of the water collection tank. A filter screen is provided on the water pumping pipe.
[0013] Furthermore, a guide plate is provided on the vehicle body on the side of the water tank away from the traction mechanism, and the guide plate is inclined and extends toward the ground.
[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:
[0015] This invention uses absorbent sponges to absorb water from the ground of deep foundation pits. A traction mechanism pulls the absorbent sponges into a water collection tank on the vehicle body. A squeezing mechanism in the water collection tank squeezes the water absorbed by the sponges, facilitating the cleaning of the water on the ground. Finally, a water pump discharges the water collected in the water collection tank out of the foundation pit. Compared with the method of workers sweeping and shoveling the water, this invention improves the convenience of the operation and the efficiency of the entire drainage operation.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0023] The following is for reference Figures 1-4 As shown in the illustration, and further explained with reference to specific embodiments, this embodiment provides a deep foundation pit drainage device, referring to... Figure 1As shown, the device includes a vehicle body 1, a water-absorbing sponge sheet 2, a traction mechanism 3, and a squeezing mechanism 4. The bottom of the vehicle body 1 is equipped with rollers 11, and a placement groove is provided on the vehicle body 1, in which a water collection tank 12 is placed. When the water-absorbing sponge sheet 2 slides outside the vehicle body 1, it can absorb the water accumulated on the ground of the deep foundation pit. When the water-absorbing sponge sheet 2 moves into the water collection tank 12, it can bring the water into the water collection tank 12. The traction mechanism 3 is located at the end of the vehicle body 1 away from the water-absorbing sponge sheet 2, and can drive the water-absorbing sponge sheet 2 to move from outside the vehicle body 1 into the water collection tank 12. The squeezing mechanism 4 is located inside the water collection tank 12 and can squeeze the water absorbed by the water-absorbing sponge sheet 2 into the water collection tank 12. When the water level in the foundation pit is pumped down to near ground level, the water-absorbing sponge 2 absorbs the residual water on the ground of the deep foundation pit. After each absorption, the water-absorbing sponge 2 is pulled into the water collection tank 12 by the traction mechanism 3. The squeezing mechanism 4 squeezes the water-absorbing sponge 2 in the water collection tank 12 so that the absorbed water flows into the water collection tank 12. Then the water-absorbing sponge 2 is placed on the ground again to absorb water until all the residual water on the ground is introduced into the water collection tank 12.
[0024] Reference Figure 2 As shown, the traction mechanism 3 includes a drive motor 31, a drive shaft 32, and a drive belt 33. Two support seats 34 are welded onto the vehicle body 1. The drive shaft 32 is rotatably connected between the two support seats 34. The drive motor 31 is fixedly mounted on one of the support seats 34 and can drive the drive shaft 32 to rotate. The drive belt 33 is wound around the drive shaft 32, and one end of the drive belt 33 away from the drive shaft 32 is fixedly connected to the water-absorbing sponge sheet 2. When the drive motor 31 is started, it drives the drive shaft 32 to rotate, which can wind up the drive belt 33. During the winding process, the drive belt 33 pulls the water-absorbing sponge sheet 2, so that the water-absorbing sponge sheet 2 enters the water collection tank 12, and the absorbed water is discharged into the water collection tank 12 when it passes through the squeezing mechanism 4.
[0025] Furthermore, a guide plate 13 is provided on the vehicle body 1 on the side of the water collection tank 12 away from the traction mechanism 3. The guide plate 13 is inclined and extends towards the ground. When the water-absorbing sponge 2 is full of water, the drive belt 33 pulls the water-absorbing sponge 2, allowing it to slide from the guide plate 13 into the water collection tank 12. Under the action of the guide plate 13, the water-absorbing sponge 2 is less likely to fold at a large angle, thereby reducing the amount of water flowing out of the water-absorbing sponge 2 before entering the water collection tank 12 and improving the water collection efficiency.
[0026] Reference Figure 2 , Figure 3As shown, the extrusion mechanism 4 includes two vertical seats 41, with a fixed roller 42 and a pressure roller 43 installed between the two vertical seats 41. The vertical seats 41 are provided with elastic pulling members 44 for driving the pressure roller 43 to move closer to the fixed roller 42. The drive belt 33 pulls the water-absorbing sponge sheet 2 to move between the fixed roller 42 and the pressure roller 43. When the water-absorbing sponge sheet 2 passes through the gap between the fixed roller 42 and the pressure roller 43, it is subjected to the pressure of the pressure roller 43 and can squeeze out the absorbed water.
[0027] Reference Figure 3 As shown, the elastic tension member 44 includes a fixed base 441, which is welded to a vertical base 41. A tension rod 442 is slidably disposed within the fixed base 441. The top end of the tension rod 442 is fixedly connected to a pressure roller 43. A connecting piece 443 is disposed on the tension rod 442, and a tension spring 444 connects the connecting piece 443 and the fixed base 441. When no external force is applied, under the elastic force of the tension spring 444, the connecting piece 443 drives the pressure roller 43 to move closer to the fixed roller 42 via the tension rod 442. At this time, the gap between the fixed roller 42 and the pressure roller 43 is less than the thickness of the absorbent sponge sheet 2, so the absorbent sponge sheet 2 can be pressed to squeeze out the accumulated water when it passes through.
[0028] Reference Figure 3 As shown, the water collection tank 12 is equipped with a release component 45 for driving the pull rod 442 to move upward so as to drive the pressure roller 43 to move away from the fixed roller 42. The release component 45 includes a mounting base 451, a release electric cylinder 452 and a release block 453. The mounting base 451 is welded to the side wall of the water collection tank 12. The cylinder of the release electric cylinder 452 is fixedly mounted on the mounting base 451. The release block 453 is fixedly connected to the piston rod of the release electric cylinder 452. The release block 453 is provided with an arc-shaped surface 4531 that can abut against the pull rod 442 and drive the pull rod 442 to move upward. After squeezing out the water from the absorbent sponge 2, the release cylinder 452 is activated and the piston rod of the release cylinder 452 is moved out of the cylinder. This allows the pull rod 442 to be lifted upward through the arc surface 4531, thereby increasing the gap between the fixed roller 42 and the pressure roller 43. Then, the drive motor 31 is activated to unwind the drive belt 33, allowing the worker to remove the absorbent sponge 2 from the vehicle body 1 and place it back on the ground to absorb the water.
[0029] Reference Figure 1 , Figure 4 As shown, the bottom wall of the water collection tank 12 is inclined, and the side of the water collection tank 12 closer to the traction mechanism 3 is lower than the side of the water collection tank 12 away from the traction mechanism 3. After the water enters the water collection tank 12, it can flow from the highest end to the lowest end to facilitate the subsequent process of pumping out the water.
[0030] Reference Figure 4 As shown, the deep foundation pit drainage device provided in this embodiment also includes a pumping mechanism 5. The pumping mechanism 5 includes a pump 51 and a pumping pipe 52. The pump 51 is located outside the deep foundation pit. One end of the pumping pipe 52 is connected to the pump 51, and the other end extends into the water collection tank 12 and is located at the lowest end of the water collection tank 12. When the pump 51 is started, the pumping pipe 52 can pump the water collected in the water collection tank 12 to the outside of the foundation pit. To prevent the pumping pipe 52 from being blocked by impurities in the collected water, a filter screen 53 is provided at the end of the pumping pipe 52 that extends into the water collection tank 12, which can intercept impurities.
[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
