Description

Technical Field

[0001] The utility model relates to the technical field of anti-seepage wall construction, in particular to a groove cleaning device based on an L-shaped steel guide wall. Background Art

[0002] During the construction process of cast-in-place concrete guide wall, it is necessary to carry out the processes of steel bar installation, formwork erection, pouring, etc., which takes up a lot of manpower, equipment and raw materials, and is expensive. Under normal climatic conditions, the time required for L-shaped steel guide wall is only 1 / 3 of the construction time of cast-in-place concrete guide wall. Based on this, L-shaped steel guide wall has been gradually widely promoted for its excellent adaptability and ability to shorten the construction period. In the construction process of L-shaped steel guide wall for anti-seepage wall, it is necessary to carry out the processes of slot excavation, steel guide wall installation, slot construction, slot cleaning construction, and casting and forming in sequence. When cleaning the slot after slot formation, it is necessary to use slot cleaning equipment to remove the sediment in the slot. Conventionally, the pump suction method can be used for reverse circulation slag discharge when cleaning the hole, and the sediment is sucked into the pump pipe and discharged from the pipe mouth. If it is not ideal, the positive circulation hole cleaning method can also be used, that is, a mud pump or air compressor is used to fill water or air into the hole through a water pipe to make the mud in the hole positively circulate to the mud pool to bring the slag sample out of the bottom of the hole.

[0003] For example, the Chinese invention patent with the announcement number CN102465536A discloses the construction process of the air lift method for cleaning the hole of the anti-seepage wall slot section, that is, after the slot section hole type is accepted, a slag discharge pipe and an air duct are set up, the slag discharge pipe is connected to the desander through a hose, the desander return slurry pipe is connected to the hole cleaning slot section, and the air duct is connected to the air compressor. Turn on the air compressor to supply air, and the mud containing drilling slag will enter the desander through the pipeline to be purified, and then flow back into the slot section. The slag discharge pipe is lengthened to clean the lower slurry until the slag discharge pipe is set close to the bottom of the slot section. After the hole is cleaned, the hole position is changed. The slag discharge pipe moves back and forth in the slot section to clean the hole until the entire slot section reaches the qualified standard and stops, and the slag discharge pipeline and related equipment are disassembled to complete the hole cleaning.

[0004] In this solution, the movement of the slag discharge pipe needs to rely on crane suspension movement, and the crane takes a long time during the overall construction process. At the same time, since the existing L-shaped steel guide wall is provided with a support between the two walls at the middle anti-seepage wall slot position, the slag discharge pipe, air duct, etc. need to be lifted when moving between different slot sections, and then lowered after passing over the support. Therefore, the construction is more dependent on the crane, and the construction cost will be increased if the crane takes a long time. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , 5 6, embodiment 1, a tank cleaning device based on an L-shaped steel guide wall, includes a mobile platform 1, on which a hoisting mechanism 2 is provided, and the mobile platform 1 is connected to a tank cleaning platform 3 through the hoisting mechanism 2. In this embodiment, the mobile platform 1 includes a frame 11, and both sides of the frame 11 are rotatably provided with groove wheels 12 for cooperating with the L-shaped steel guide wall. By setting up the mobile platform, it can cooperate with the L-shaped steel guide wall to achieve movement along the middle of the L-shaped steel guide wall. By setting up the hoisting mechanism, the bottom tank cleaning part such as the tank cleaning platform and other related structures can be hoisted, replacing the crane function in the prior art, reducing the occupation of the crane, and reducing costs.

[0024] In addition, a tank cleaning guide device 4 is provided on the tank cleaning platform 3, and the tank cleaning guide device 4 is connected to a tank cleaning pump 6 through a conveying pipeline 5. By providing the tank cleaning guide device, the tank cleaning platform can be guided, and at the same time, the tank cleaning platform can cooperate with the tank cleaning platform to provide a gathering guide for the tank cleaning pump to pump the slag through the conveying pipeline.

[0025] In this embodiment, Figure 4As shown, a protrusion is provided on the inner side of the grooved wheel 12, and the wheel surface of the grooved wheel cooperates with the top surface of the L-shaped steel guide wall. The two grooved wheels can only move along the slot position in the middle of the L-shaped steel guide wall, and the inner protrusion is used to limit the lateral displacement of the grooved wheel.

[0026] In addition, as a further embodiment, a driving motor is provided on the stand 11, and the output end of the driving motor is connected to the wheel shaft of the groove wheel through a belt transmission pair. When the whole device needs to be moved or the slot cleaning position needs to be moved, the driving motor works to drive the groove wheel to rotate, and then move along the length direction of the slot hole of the L-shaped steel guide wall. This device can be applied to the construction of an anti-seepage wall with an L-shaped steel guide wall, such as Figure 5 The figure shows the coordination state of the device and the steel formwork guide wall in the patent with announcement number CN211621616U. Figure 6 This is a schematic diagram of the device in use with another L-shaped steel guide wall. Since the L-shaped steel guide wall has a standard-sized, extremely strong outer wall and right-angled edges at the edge of the slot hole, it can be used as a supporting foundation for the setting and installation of the device. The device is easy to move and has strong flexibility when in use, avoiding the long-term occupation of the construction crane during the slot cleaning process.

[0027] Embodiment 2 is a trough cleaning device based on an L-shaped steel guide wall. On the basis of Embodiment 1, the hoisting mechanism 2 includes a traction machine 21 fixed on a platform 11, and the traction end of the traction machine 21 is connected to the trough cleaning platform 3.

[0028] Further, in this embodiment, if Figure 2 As shown, the platform 11 is an "I"-shaped frame, and the traction machine 21 is arranged on the top of the "I"-shaped frame, and the traction machine 21 can lift the cleaning platform 3 to the opening of the "I"-shaped frame. Among them, at least two traction machines 21 are arranged to maintain balance. In this embodiment, a total of four small traction machines are arranged, and the four small traction machines share the same drive motor, which can smoothly lift the cleaning platform at the bottom. When moving to the support part between the L-shaped steel guide walls, the traction machine works to lift the entire cleaning platform and the cleaning guide device to the opening of the "I"-shaped frame, and after passing the support part, it is lowered to the bottom of the slot hole again for slag cleaning.

[0029] Embodiment 3, a trough cleaning device based on L-shaped steel guide wall, based on embodiment 2, as Figure 3As shown, the tank cleaning platform 3 includes a frame 31 connected to the traction end of the traction machine 21, and a collecting bucket trough 33 is provided on the frame 31. The front end and the lower end of the collecting bucket trough 33 are both open, and the rear end is connected to the conveying pipeline. A counterweight iron 35 is provided on the collecting bucket trough 33. In this embodiment, since mud is required to protect the wall before slag cleaning, there is a large amount of mud in the slot hole of the anti-seepage wall during slag cleaning. The counterweight iron can be provided to increase the weight of the collecting bucket trough and sink to the bottom. As the tank cleaning pump absorbs mud, negative pressure is generated inside the collecting bucket trough, and the negative pressure pushes the collecting bucket trough forward.

[0030] As a further embodiment, the tank cleaning guide device 4 includes a guide wheel 41 disposed at the front end of the collecting bucket tank 33. The guide wheels 41 are arranged in pairs and are rotatably disposed at the front ends of the two side walls of the collecting bucket tank 33. In this embodiment, the guide wheel 41 is a roller-shaped guide wheel, which is vertically rotatably disposed on the two side walls of the front end of the collecting bucket tank, and is used to contact the anti-seepage wall slot holes on both sides to play a guiding role.

[0031] As a further optional embodiment, walking wheels 32 are provided on the side walls of the collecting bucket groove 33, and the walking wheels can contact the ground to facilitate movement. At the same time, a circular chamfer is provided at the front end of the collecting bucket groove to further facilitate forward movement.

[0032] In addition, the tank cleaning pump 6 is fixed on the mobile platform 1, and the input port of the tank cleaning pump 6 is connected to the conveying pipe 5, and the output port faces one side of the mobile platform 1. In this embodiment, the conveying pipe 5 is a bellows. Furthermore, the bellows of this embodiment is a steel wire bellows, which provides better conveying capacity. When cleaning the tank, the collecting bucket moves synchronously with the mobile platform. After the tank cleaning pump is turned on, the slag at the bottom is sucked into the tank cleaning pump through the conveying pipe under the diversion effect of the collecting bucket, and is discharged to one side of the anti-seepage wall slot through the output port, or discharged to the slag truck or slag tank in the construction site through the pipe. As a further optional method, as the slag cleaning process proceeds, the mud level in the anti-seepage wall slot becomes low. At this time, it is necessary to continue to add mud to the inside of the slot to maintain the wall protection effect.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
