Description

Technical Field

[0001] This utility model relates to the field of grouting devices, specifically to a filter screen grouting device for preventing glue overflow. Background Technology

[0002] A grouting device is a piece of equipment used to inject grout into strata, rock fissures, building structural cracks, or concrete to achieve engineering purposes such as reinforcement, seepage prevention, and leak sealing. Its working principle is based on hydraulic, pneumatic, or electrochemical principles, injecting the prepared grout evenly and continuously into the target area through a pipeline system.

[0003] A search revealed a utility model patent with publication number CN202214729U, which specifically discloses a rapid grouting sealing device. The purpose of this utility model is to provide a simple and easy-to-operate rapid grouting sealing device that can efficiently and cost-effectively solve the sealing problem at any hole depth in the presence of pressurized water. The technical solution of this utility model is: a rapid grouting sealing device, including a steel pipe for conveying grout, characterized in that: a positioning ring is set on the steel pipe at the part to be sealed, and a hard wedge-shaped ring and a flexible ring are sequentially fitted on the steel pipe on the side of the positioning ring's orifice. This utility model is applicable to rapid grouting sealing in various small-diameter drilling grouting fields.

[0004] In the process of using existing grouting devices, it is necessary to drill a hole in the hollow part and then insert the grouting device into the hole to deliver the grouting adhesive. However, during the delivery process, due to the high internal pressure, adhesive overflow may occur. Therefore, a simple sealing treatment is usually used at the connection between the hole and the grouting injection pipe. However, this method can still cause the grouting adhesive to overflow under high pressure, affecting the normal grouting construction.

[0005] Therefore, it is necessary to invent a filter screen grouting device to prevent glue overflow in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a filter screen grouting device that prevents glue overflow. By actively controlling the opening and closing of the return chamber and return groove, the pressure is reduced, thereby avoiding glue overflow. This solves the problem in the prior art where glue overflow occurs due to high pressure during construction, thus affecting normal grouting construction.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filter screen grouting device for preventing glue overflow, comprising a base, a pressurized storage tank installed above the base, a feed hopper connected through the top of the pressurized storage tank, a conveying hose connected through the bottom of the pressurized storage tank, an injection cylinder provided on the side of the conveying hose away from the pressurized storage tank, and a filter screen provided inside the injection cylinder;

[0008] The anti-overflow adhesive component installed in the injection cylinder includes an annular groove, which is opened on the inner wall of the injection cylinder. Multiple sets of return chambers are arranged in an annular pattern inside the injection cylinder. Multiple sets of through holes are opened between the return chambers and the inner wall of the annular groove, and each set of through holes is sealed and fitted to the outside of the filter screen. A return groove is opened between the bottom of the return chamber and the lower inner wall of the injection cylinder.

[0009] The control component located above the injection cylinder includes a docking cylinder that is threadedly connected to the injection cylinder.

[0010] Preferably, the anti-overflow adhesive assembly further includes a slide bar, which is installed in a ring shape below the inner wall of the annular groove.

[0011] Preferably, the bottom of the filter screen has multiple sets of docking holes arranged in a ring, and the docking holes are slidably connected to the corresponding slide rods.

[0012] Preferably, a spring is sleeved on the slide rod, and the two sides of the spring are respectively attached to the bottom of the filter screen and the inner wall of the annular groove.

[0013] Preferably, multiple sets of conical rings are sequentially installed on the inner wall of the reflux trough, with the conical openings of the conical rings facing the reflux cavity, and a rubber sealing ring is fitted and fixed on the injection cylinder.

[0014] Preferably, the control component further includes push rods, which are installed in a ring below the docking cylinder, with the lower part of each set of push rods fitting against the upper part of the filter screen.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By rotating the docking cylinder, it moves closer to the injection cylinder, causing the filter screen to move downwards and exposing the through hole. At this point, the return trough can transport the high-pressure grout into the return chamber and then into the injection cylinder through the through hole, thus completing a cycle. This prevents overflow due to excessive pressure. Furthermore, the docking cylinder and injection cylinder can be disassembled for quick cleaning after construction. This structure allows for active control and release of pressure during grouting, preventing overflow and ensuring the normal progress of construction. This structure is also relatively simple and easy to disassemble, facilitating later maintenance and cleaning. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The filter screen grouting device for preventing glue overflow shown includes a base 001, a pressurized storage tank 101 installed above the base 001, a feed hopper 102 connected through the top of the pressurized storage tank 101, a conveying hose 103 connected through the bottom of the pressurized storage tank 101, an injection cylinder 104 provided on the side of the conveying hose 103 away from the pressurized storage tank 101, and a filter screen 105 provided inside the injection cylinder 104;

[0027] The pressurized storage tank 101 can deliver the grouting adhesive inside to the injection cylinder 104 through the delivery hose 103, and the filter screen 105 can filter out larger impurities in the grouting adhesive.

[0028] The anti-overflow adhesive assembly 002 installed in the injection cylinder 104 includes an annular groove 201, which is formed on the inner wall of the injection cylinder 104. Multiple sets of return chambers 205 are arranged in annularly inside the injection cylinder 104. Multiple sets of through holes 206 are formed between the return chambers 205 and the inner wall of the annular groove 201, and each set of through holes 206 is sealed and fitted to the outer side of the filter screen 105. A return groove 207 is formed between the bottom of the return chamber 205 and the lower inner wall of the injection cylinder 104.

[0029] The grouting adhesive that enters below the injection cylinder 104 can be transported back to the grouting cavity 205 through the return groove 207, and then transported back to the annular groove 201 through the through hole 206.

[0030] The control component 003, located above the injection cylinder 104, includes a docking cylinder 301, which is threadedly connected to the injection cylinder 104.

[0031] By actively rotating the docking cylinder 301 or the injection cylinder 104, the two can be brought closer together or separated. When separated, it is convenient to clean the inside of the injection cylinder 104.

[0032] Furthermore, in the above structure, the anti-overflow adhesive assembly 002 also includes a slide bar 202, which is installed in a ring shape below the inner wall of the annular groove 201.

[0033] Furthermore, in the above structure, the bottom of the filter screen 105 has multiple sets of docking holes 203 arranged in a ring, and the docking holes 203 are slidably connected to the corresponding slide rods 202.

[0034] The filter screen 105 can slide up and down inside the injection cylinder 104 by the cooperation of the slide rod 202 and the docking hole 203.

[0035] Furthermore, in the above structure, a spring 204 is sleeved on the slide rod 202, and the two sides of the spring 204 are respectively attached to the bottom of the filter screen 105 and the inner wall of the annular groove 201.

[0036] The spring 204 can keep the filter screen 105 in position within the injection cylinder 104, and when the pressure is too high, it can squeeze the filter screen 105, causing it to squeeze the spring 204 below, thereby moving the filter screen 105.

[0037] Furthermore, in the above structure, multiple sets of conical rings 208 are sequentially installed on the inner wall of the reflux trough 207, and the conical opening of the conical ring 208 faces the reflux cavity 205. A rubber sealing ring 209 is sleeved and fixed on the injection cylinder 104.

[0038] The conical ring 208 can create a flow velocity difference inside the return channel 207, thereby controlling the flow direction inside the return channel 207. The rubber sealing ring 209 can be pressed to fit against the ground or other positions, thereby forming a seal between the injection cylinder 104 and the grouting hole.

[0039] Furthermore, in the above structure, the control component 003 also includes push rods 302, which are installed in a ring below the docking cylinder 301, and the lower part of each set of push rods 302 is attached to the upper part of the filter screen 105.

[0040] As the docking cylinder 301 moves downward, the push rod 302 pushes the filter screen 105 to move, exposing the through hole 206. At this time, the grouting adhesive with high pressure will return to the position above the injection cylinder 104 along the through hole 206, avoiding the situation of overflow due to high pressure.

[0041] The working principle of this practical application is as follows:

[0042] Refer to the instruction manual appendix Figure 1-5 By drilling a hole at the hollow location requiring grouting, the injection cylinder 104 can pass through the hole, and the rubber sealing ring 209 fits against the periphery of the hole to form a certain seal. At this time, the grout is continuously delivered into the hollow location through the pressurized storage tank 101. During this process, the injection cylinder 104 needs to be pressed to prevent loosening. As the pressure increases, the position of the docking cylinder 301 can be rotated, causing the push rod 302 to press the filter screen 105 downwards, thus exposing the through hole 206. At this point, the injection cylinder... The glue below 104 will flow into the return chamber 205 through the return groove 207, and finally re-enter the injection cylinder 104 through the through hole 206, thereby achieving the effect of pressure release and avoiding glue overflow. After the construction is completed, the inside of the injection cylinder 104 can be exposed by separating the docking cylinder 301, which facilitates internal cleaning. This structure allows for active control and release of pressure during the grouting process to avoid glue overflow. This structure is also relatively simple and easy to disassemble, making it convenient for later maintenance and cleaning.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
