Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure grouting, in particular to a high-pressure grouting device for treating raft leakage. Background Technique

[0002] The treatment of raft leakage is an important maintenance measure in foundation engineering, aiming to ensure the safety and stability of buildings; when treating raft leakage, the following steps need to be carried out:

[0003] 1. External waterproof treatment: First, clean the surface of the raft to remove sundries, dirt and loose concrete to ensure the adhesion of the waterproof material; then use epoxy resin or cement-based repair materials to fill the cracks on the surface of the raft to ensure it is smooth and flat; then evenly apply waterproof paint on the surface of the raft; finally, install a protective layer after the waterproof paint cures to protect the waterproof layer;

[0004] 2. Internal grouting treatment: First, determine the location of the leakage point through visual inspection and water tightness test; then drill holes at appropriate positions around the leakage point, and then install the grouting needles for high-pressure grouting into the drilled holes. Finally, use a high-pressure grouting device to inject grouting materials (such as cement-based or polyurethane materials) through the grouting needles into the leakage part. After the grouting is completed, keep the area dry. After the grouting material cures, the repair of the leakage is completed;

[0005] 3. Reinforcement treatment: First, select a suitable reinforcement plan according to the stress condition of the raft, such as adding a steel bar framework under or on the side of the raft, or using carbon fiber cloth for reinforcement. And after reinforcement, it is necessary to regularly monitor the displacement and deformation of the raft to ensure its stability.

[0006] However, the existing high-pressure grouting devices usually include multiple parts such as a pump body, a pressure vessel, a pipeline system, etc., and their volumes are usually large. For this reason, rollers are often installed at the lower end of the high-pressure grouting device to facilitate the user to push it for movement, thereby reducing the handling difficulty. However, if the construction position of the high-pressure grouting device is on a ramp or an uneven surface; it will cause the device to tilt, resulting in a shift of the center of gravity, causing the device to slide on the ramp. Even if the rollers are equipped with a braking device, the high-pressure grouting device will still have a higher risk of tipping due to the high or uneven distribution of the center of gravity; further damaging the device or causing personal injuries. For this reason, additional manpower is often required to support the tilted high-pressure grouting device, thereby increasing the labor cost. Content of the Utility Model

[0007] Purpose of the utility model: The purpose of the utility model is to provide a high-pressure grouting device for treating raft leakage in view of the deficiencies of the existing technology.

[0008] Technical solution: The high-pressure grouting equipment for raft leakage treatment of the present utility model includes a base; a chassis is fixedly installed at the upper end of the base; rollers are installed at the lower end of the base; a high-pressure pump is installed inside the chassis; a pressure tank is fixedly installed at the upper end of the base; a connecting pipe is fixedly installed on one side of the pressure tank; the connecting pipe is connected to the high-pressure pump through a flange nut; a rectangular groove is opened at the lower end of the base; a support plate is slidably and sealingly connected in the rectangular groove; the support plate is made of fluororubber material; a hydraulic push rod is arranged above the support plate; one end of the hydraulic push rod close to the support plate is hinged to the support plate through a torsion spring; the other end of the hydraulic push rod away from the support plate penetrates through the base and is located inside the chassis; the hydraulic push rod is fixedly connected to the base.

[0009] Preferably, an installation groove is opened at the lower end of the base; a slider is slidably and sealingly connected in the installation groove; the roller is rotatably connected to one end of the slider away from the installation groove; a corrugated airbag is arranged in the rectangular groove; a connecting spring is installed inside the corrugated airbag; the corrugated airbag is fixedly connected to the bottom of the rectangular groove; an oil passage is opened inside the base; one end of the oil passage is communicated with the corrugated airbag, and the other end is communicated with the installation groove.

[0010] Preferably, a convex strip is fixedly connected to the surface of the support plate away from the hydraulic push rod; the shape of the convex strip is set to be V-shaped.

[0011] Preferably, a threaded groove is opened at the upper end of the base; a rotating ring is rotatably connected in the threaded groove; the rotating ring is sleeved on

[0012] Beneficial effects:

[0013] 1. In this solution, by setting the corrugated airbag to be communicated with the installation groove through the oil passage, during storage, the corrugated airbag is pushed by the connecting spring and is in an extended state, so that the hydraulic oil in the installation groove can flow back into the corrugated airbag through the oil passage, enabling the slider to drive the roller into the installation groove, preventing the roller from protruding out of the installation groove, ensuring that the base can contact the ground through a horizontal lower end surface, and then changing the rolling contact between the base and the ground to sliding contact, increasing the contact area and friction force between the base and the ground, thereby improving the placement stability of this solution. At the same time, the roller is retracted into the installation groove, reducing the overall height of this solution, saving storage space, and improving space utilization rate.

[0014] 2. This solution facilitates the quick removal of the pressure tank from the upper end face of the base by a single person through the setting of a swivel ring, enabling the single person to separate the pressure tank from the high-pressure pump installed in the chassis and carry them independently, thus eliminating the need for additional personnel assistance. This makes it convenient for the user to turn or adjust the direction in a narrow corridor, thereby reducing the handling difficulty and achieving the effect of single-person handling. After carrying it upstairs, the user can thread the swivel ring into the threaded groove, and the swivel ring can then press the pressure tank against the base through the flange on the surface of the pressure tank, thus quickly completing the installation of the pressure tank.

[0015] 3. This solution is equipped with a hydraulic push rod, which can push the support plate out of the rectangular groove to contact the inclined slope of the steep slope. Blocked by the slope, the continuously extending hydraulic push rod can push one end of the base facing the bottom of the steep slope to rotate upward and rise, causing the base to rotate to a horizontal state. After that, the pressure tank and high-pressure pump installed on the base will no longer be inclined; thus, their center of gravity is corrected, avoiding the risk of tipping due to a high or unevenly distributed center of gravity, improving the operation safety of this solution. Additionally, there is no need for extra manpower to support the inclined high-pressure grouting equipment, facilitating one-person operation and use, thereby reducing labor costs and lowering the operation difficulty.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solution of the present utility model will be described in detail below with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the described embodiments.

[0023] Embodiment 1: A high-pressure grouting device for raft leakage treatment, including a base 1; a chassis 2 is fixedly installed at the upper end of the base 1; rollers 11 are installed at the lower end of the base 1; a high-pressure pump 21 is installed inside the chassis 2; a pressure tank 12 is fixedly installed at the upper end of the base 1; a connecting pipe 13 is fixedly installed on one side of the pressure tank 12; the connecting pipe 13 is connected to the high-pressure pump 21 through a flange nut 14; a rectangular groove 15 is opened at the lower end of the base 1; a support plate 22 is slidably and sealingly connected in the rectangular groove 15; the support plate 22 is made of fluororubber material; a hydraulic push rod 23 is arranged above the support plate 22; one end of the hydraulic push rod 23 close to the support plate 22 is hinged to the support plate 22 through a torsion spring; the other end of the hydraulic push rod 23 away from the support plate 22 penetrates through the base 1 and is located inside the chassis 2; the hydraulic push rod 23 is fixedly connected to the base 1.

[0024] As an implementation manner of this solution, an installation groove 16 is opened at the lower end of the base 1; a slider 17 is slidably and sealingly connected in the installation groove 16; the roller 11 is rotatably connected to one end of the slider 17 away from the installation groove 16; a corrugated airbag 24 is arranged in the rectangular groove 15; a connecting spring 25 is installed inside the corrugated airbag 24; the corrugated airbag 24 is fixedly connected to the bottom of the rectangular groove 15; an oil passage 26 is opened inside the base 1; one end of the oil passage 26 is communicated with the corrugated airbag 24, and the other end is communicated with the installation groove 16.

[0025] As an implementation manner of this solution, a convex strip 27 is fixedly connected to the surface of the support plate 22 away from the hydraulic push rod 23; the shape of the convex strip 27 is set to be V-shaped.

[0026] As an implementation manner of this solution, a threaded groove 3 is opened at the upper end of the base 1; a rotating ring 31 is rotatably connected in the threaded groove 3; the rotating ring 31 is sleeved on the surface of the pressure tank 12; a flange 32 is fixedly connected to the surface of the pressure tank 12.

[0027] The working principle is as follows:

[0028] When storing: The pressure tank 12 is installed on the upper end of the base 1, and the high-pressure pump 21 is installed inside the chassis 2. A machine door is installed on one side of the chassis 2. When the machine door is opened, the grouting needle for grouting and the hose connecting the grouting needle and the pressure tank 12 can be placed inside the chassis 2 for storage; Subsequently, control the hydraulic push rod 23 to pull the support plate 22 into the rectangular groove 15, and the lower end surface of the support plate 22 is in the same plane as the lower end surface of the bottom plate, so that the corrugated airbag 24 located in the rectangular groove 15 is not squeezed by the support plate 22. At this time, the corrugated airbag 24 is in an extended state under the support of the restoring force of the internal connecting spring 25. Although the corrugated airbag 24 is connected to the installation groove 16 through the oil passage 26, due to the corrugated airbag 24 pushed by the connecting spring 25 being in an extended state, the space inside the corrugated airbag 24 increases at this time, and the pressure decreases. As a result, the hydraulic oil in the installation groove 16 will enter the corrugated airbag 24 through the oil passage 26 under the push of the pressure difference, so that the corrugated airbag 24 is filled with hydraulic oil; At this time, the hydraulic oil in the installation groove 16 decreases and the pressure drops, so that different pressure differences are generated on the upper and lower sides of the slider 17, so that the slider 17 drives the roller 11 to be located in the installation groove 16 under the push of the pressure difference; At this time, the base 1 contacts the ground through the lower end surface;

[0029] When using: The user first determines the location of the leakage point through visual inspection and water tightness test; Subsequently, use a handheld drill to drill holes at appropriate positions around the leakage point, then open the chassis 2, take out the grouting needle for high-pressure grouting and install it into the drilled hole, then connect one end of the hose in the chassis 2 to the pressure tank 12 and the other end to the grouting needle, and finally turn on the high-pressure pump 21 to inject the grouting material (such as cement-based or polyurethane material) into the leakage part through the grouting needle. After the grouting is completed, keep the area dry. After the grouting material solidifies, the repair of the leakage is completed;

[0030] During flat ground transportation: When it is necessary to move the high-pressure grouting equipment on flat ground, the user needs to control the hydraulic push rod 23 to contract; so that the hydraulic push rod 23 pulls the support plate 22 completely into the rectangular groove 15; and during the process of the support plate 22 entering the rectangular groove 15, the rectangular plate will squeeze the corrugated airbag 24, causing the connecting spring 25 in the corrugated airbag 24 to be pushed and compressed. At this time, the hydraulic oil in the corrugated airbag 24 is squeezed and enters the installation groove 16 through the oil passage 26, so that the hydraulic oil entering the installation groove 16 can push the slider 17 to move away from the bottom of the installation groove 16, causing the slider 17 to drive the roller 11 rotatably connected at the lower end to shoot out of the installation groove 16, so that the roller 11 can contact the ground. As the hydraulic oil continuously pushes the slider 17 out of the installation groove 16, the slider 17 drives the roller 11 to move relative to the base 1. Since the roller 11 is blocked by the ground, the base 1 is pushed by the hydraulic oil and rises; the base 1 is separated from the ground, so that the base 1 rolls on the ground through the roller 11. Subsequently, the user only needs to push the box body, and the box body can move on the ground through the roller 11 at the lower end of the base 1, thereby saving the driving force and facilitating the user to transport it on flat ground;

[0031] During transportation in the corridor: Since both the high-pressure pump 21 and the pressure tank 12 are metal components and are installed on the base 1, it will greatly increase the weight of handling. Therefore, during the process of carrying in the corridor, usually two staff members are required for carrying. However, if the corridor is narrow, the activities of two people will be restricted. Especially when turning or adjusting the direction in a narrow corridor, the two people will have difficulty in coordination or interfere with each other, thus increasing the difficulty of carrying; In response to this, to facilitate a single person to carry the high-pressure grouting equipment, in this solution, by setting the rotating ring 31, before carrying, the user first rotates the flange nut 14 to separate the connecting pipe 13 of the pressure tank 12 from the high-pressure pump 21, and then rotates the rotating ring 31 so that the rotating ring 31 is threaded out of the internal thread of the threaded groove 3, so that the rotating ring 31 no longer presses the flange 32, so that the pressure tank 12 can be quickly disassembled from the upper end surface of the base 1, so as to facilitate a single person to separate the pressure tank 12 and the high-pressure pump 21 installed in the chassis 2 and carry them independently, thus eliminating the need for additional personnel assistance, facilitating the user to turn or adjust the direction in a narrow corridor, and further reducing the carrying difficulty and achieving the effect of single-person carrying; When carried to the upper floor, the user then threads the rotating ring 31 into the threaded groove 3, and the rotating ring 31 can press the pressure tank 12 on the base 1 through the flange 32 on the surface of the pressure tank 12, thereby quickly completing the installation of the pressure tank 12;

[0032] Installation on a steep slope: When the base 1 is located on a steep slope and needs to be fixed, first orient the end of the base 1 close to the support plate 22 towards the lower end of the steep slope. Control the hydraulic push rod 23 to extend, so that the hydraulic push rod 23 can push the support plate 22 out of the rectangular groove 15, making the support plate 22 contact the ground. As the hydraulic push rod 23 continues to extend, it causes the hydraulic push rod 23 to push the support plate 22 away from the base 1. Due to the ground blocking the support plate 22, the hydraulic push rod 23 pushes the base 1 upward until the base 1 is in a horizontal state, thus preventing the pressure tank 12 and the high-pressure pump 21 installed on the base 1 from tilting; avoiding the risk of tipping due to a high center of gravity or uneven distribution, improving the operational safety of this solution; moreover, the setting of the V-shaped ridges 27 increases the friction between the support plate 22 and the slope surface of the steep slope, and then enables the base 1 to be stably supported on the slope through the support plate 22, ensuring the stability and safety of the grouting operation.

[0033] Finally, the advantages of this solution compared with the prior art are as follows:

[0034] 1. In this solution, the corrugated airbag 24 and the installation groove 16 are connected through the oil passage 26. During storage, the corrugated airbag 24 is pushed by the connecting spring 25 to be in an extended state, so that the hydraulic oil in the installation groove 16 can flow back into the corrugated airbag 24 through the oil passage 26, causing the slider 17 to drive the roller 11 into the installation groove 16, preventing the roller 11 from protruding out of the installation groove 16, ensuring that the base 1 can contact the ground through a horizontal lower end surface, and then changing the rolling contact between the base 1 and the ground to sliding contact, increasing the contact area and friction between the base 1 and the ground, thereby improving the stability of the placement of this solution. At the same time, the roller 11 is retracted into the installation groove 16, reducing the overall height of this solution, saving storage space, and improving space utilization.

[0035] 2. By setting the swivel ring 31 in this solution, it is convenient for a single person to quickly disassemble the pressure tank 12 from the upper end surface of the base 1, facilitating the separation and independent handling of the pressure tank 12 and the high-pressure pump 21 installed in the chassis 2 by a single person, without the need for additional personnel assistance, making it convenient for the user to turn or adjust the direction in a narrow corridor, thereby reducing the handling difficulty and achieving the effect of single-person handling; after transporting to the upper floor, the user can thread the swivel ring 31 into the threaded groove 3, enabling the swivel ring 31 to press the pressure tank 12 against the base 1 through the flange 32 on the surface of the pressure tank 12, and then quickly completing the installation of the pressure tank 12.

[0036] 3. By setting the hydraulic push rod 23, the hydraulic push rod 23 can push the support plate 22 to extend out of the rectangular groove 15 and contact the inclined slope of the steep slope. Blocked by the slope, the continuously extending hydraulic push rod 23 can push one end of the base 1 towards the bottom of the steep slope to rotate upward and rise. After the base 1 rotates to a horizontal state, the pressure tank 12 and the high-pressure pump 21 installed on the base 1 will no longer be inclined; thereby making its center of gravity return to normal, avoiding the risk of tipping over due to a high or unevenly distributed center of gravity, improving the operation safety of this solution, and also eliminating the need for additional manpower to support the inclined high-pressure grouting equipment, facilitating one-person operation and use, thereby reducing labor costs and lowering the operation difficulty.

[0037] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation on the present invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the present invention as defined by the appended claims.
