Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, specifically to a dual-liquid grouting device. Background Technology

[0002] Grouting devices, also known as injection systems, are technical equipment used in building engineering and soil and rock reinforcement. They inject cement grout or chemical grout into the strata, cracks, or cavities. When the joint is deep, cement-water glass grout alone is insufficient to penetrate to the deepest parts, necessitating chemical grouting. Chemical grouting involves delivering a solution of inorganic or organic chemical materials to the joint, allowing it to penetrate, diffuse, and solidify to repair and reinforce the joint. Existing technologies, such as patent publication number CN209243727U, disclose an adjustable pressure grouting system for concrete deformation joints, including a grout storage tank with three connection holes at the top. One vent pipe is connected to an air compressor via a first valve, and another high-pressure pipe via a second valve is connected to an air compressor equipped with a pressure gauge. The third grout supply pipe is connected to a grout supply pump via a grout suction pipe. The grout supply pump is connected to a grout mixing tank via a suction pipe. The bottom of the grout storage tank is connected to a grouting pipe equipped with a fourth valve and a pressure sensor. The air compressor and pressure sensor are both connected to the controller circuit via data lines. The grouting pressure is controlled by the air compressor and pressure gauge, and the grouting pressure can be adjusted in real time according to the construction intensity requirements. However, the device only has a single grout storage tank, which makes it difficult to perform dual-liquid grouting, and is not conducive to further improving the application range and practicality of the device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-liquid grouting device includes two branch grouters. Each branch grouter includes a single-liquid storage tank equipped with a single-liquid chemical grouting pump. The top of the single-liquid storage tank is connected to an air compressor via an air inlet pipe. A valve and a first pressure gauge are sequentially installed on the air inlet pipe. The single-liquid chemical grouting pump is used to transport the grout from the single-liquid storage tank to a branch pipeline. A flow regulating valve and a one-way valve are sequentially installed on the branch pipeline. The two branch pipelines converge into a main grouting pipeline. The branch pipelines and the main grouting pipeline are connected by a quick connector. The main grouting pipeline is equipped with a gate valve and a grouting port at its end. The branch grouters are arranged on branch supports, and the gate valve and the main grouting pipeline are located on the main support.

[0006] In some embodiments of this utility model, an electromagnetic flow meter is arranged on the branch pipe, and the electromagnetic flow meter is arranged after the check valve.

[0007] In some embodiments of this utility model, an inspection port is provided between the gate valve and the grouting pipe, a second pressure gauge is installed at the inspection port, and an isolator is provided in front of the second pressure gauge.

[0009] In some embodiments of this utility model, several bucket limiting rods are vertically arranged on the sub-support, and the bucket limiting rods are all located on the outside of the single liquid storage tank.

[0010] In some embodiments of this utility model, the single-liquid slurry storage tank is arranged in the middle of the main support, and the arrangement height of the single-liquid slurry storage tank is higher than the arrangement height of the end outlet of the main grouting pipe.

[0011] In some embodiments of this utility model, the main grouting pipe includes a front pipe and a rear confluence pipe, and a grout mixing chamber is provided between the front pipe and the rear confluence pipe. The grout mixing chamber includes a primary guide chamber and a secondary mixing chamber. The branch pipe is connected to the primary guide chamber through the front pipe, and a gate valve is provided in the rear confluence pipe.

[0012] In some embodiments of this utility model, two front pipes are symmetrically arranged on both sides of the mixing chamber, and the primary guide chamber is provided with a guide channel for guiding the slurry to the secondary mixing chamber.

[0028] See the example. Figure 1 :

[0029] A dual-liquid grouting device includes two branch grouters. Each branch grouter includes a single-liquid grout storage tank 1. The top of the single-liquid grout storage tank 1 is connected to an air compressor via an air inlet pipe 11. A valve 10 and a first pressure gauge are sequentially installed on the air inlet pipe 11. The air compressor is used to provide compressed air and help stabilize the grouting pressure. The single-liquid grout storage tank 1 is equipped with a single-liquid chemical grouting pump, which is used to transport the grout in the single-liquid grout storage tank 1 to a branch pipe 2. A flow regulating valve 20 and a one-way valve 21 are sequentially installed on the branch pipe 2. The two branch pipes 2 converge into a main grouting pipe 4. The branch pipes 2 and the main grouting pipe 4 are connected by a quick connector 23 to facilitate quick loading and unloading between the branch pipes 2 and the main grouting pipe 4. Preferably, an electromagnetic flow meter 22 is arranged on the branch pipe 2. The electromagnetic flow meter 22 is arranged after the one-way valve 21, so that the slurry enters the main grouting pipe 4 after passing through the flow regulating valve 20, the one-way valve 21, and the electromagnetic flow meter 22 in sequence. The electromagnetic flow meter 22 is used to detect the grouting flow of the branch grouter.

[0030] The main grouting pipe 4 is equipped with a gate valve 40, and a grouting port 45 is provided at the end of the main grouting pipe 4. The grout enters from the branch pipe 2 and flows out from the grouting port 45.

[0031] The sub-grouting device is arranged on the sub-support 3, and the gate valve 40 and the main grouting pipe 4 are located on the main support 6. When dual-liquid grouting is required, the sub-support 3 moves to one side of the main support 6 and connects the sub-pipe 2 and the main grouting pipe 4 through the quick connector 23. Different grouts are placed in the single-liquid storage tanks 1 of the two sub-grouting devices. The grout enters the main grouting pipe 4 through the sub-pipe 2 and finally flows out from the grouting port 45. When only single-liquid grouting is required, the sub-grouting device is used alone. Under the action of the single-liquid chemical grouting pump, the grout flows out from the sub-pipe 2.

[0032] In one embodiment, an inspection port 43 is provided between the gate valve 40 and the grouting pipe port 45. A second pressure gauge 44 is installed in the inspection port 43. An isolator is provided in front of the second pressure gauge 44. The second pressure gauge 44 is used to detect the grouting pressure. After the grouting is completed, the user can remove the second pressure gauge 44 and observe the inside of the main grouting pipe 4 through the inspection port 43. At the same time, it is convenient to flush the main grouting pipe 4.

[0033] In one embodiment, the main support 6 is provided with a placement platform 60, which is located on one side of the inspection port 43. A storage cabinet 61 is provided below the placement platform 60 so that when the user removes the second pressure gauge 44, it is convenient to place the second pressure gauge 44 on the placement platform 60.

[0034] In one embodiment, the support bracket 3 is vertically provided with several barrel limiting rods 30, all of which are located on the outside of the single liquid storage tank 1.

[0035] In one embodiment, the single-liquid slurry storage tank 1 is arranged in the middle of the main support 6, and the arrangement height of the single-liquid slurry storage tank 1 is higher than the arrangement height of the end outlet of the main grouting pipe 4.

[0036] In one implementation, the main grouting pipe 4 includes a front pipe 41 and a rear manifold pipe 42. A grout mixing chamber 5 is provided between the front pipe 41 and the rear manifold pipe 42. The grout mixing chamber 5 includes a primary guide chamber 50 and a secondary mixing chamber 51. The branch pipe 2 is connected to the primary guide chamber 50 through the front pipe 41. It can be understood that the gate valve 40, inspection port 43, and grouting pipe port 45 are located in the rear manifold pipe 42. The rear manifold pipe 42 includes a front section and a rear section, which are connected by a tee joint. The inspection port 43 is arranged at the third joint of the tee joint. In practical applications, the tee joint is a positive tee. The grout mixing chamber 5 is arranged horizontally or inclined downwards.

[0037] In one embodiment, two front pipes 41 are symmetrically arranged on both sides of the mixing chamber 5. The primary guide chamber 50 is provided with a guide channel for guiding the slurry to the secondary mixing chamber 51. The inner wall of the secondary mixing chamber 51 is provided with a spiral flow channel, which helps the two sets of slurries to flow and mix, improving the mixing effect. At the same time, the spiral flow channel plays a disturbing role for the mixed slurry, reducing the retention and settling of the slurry. In use, the slurry from the branch pipe 2 enters the secondary mixing chamber 51 through the primary guide chamber 50. The slurries from the two branch injectors are mixed in the secondary mixing chamber 51 and then enter the rear confluence pipe 42. In this embodiment, the primary guide chamber 50 is directly opposite the front end face of the secondary mixing chamber 51. In some other embodiments, the primary guide chamber 50 is connected from the front side of the secondary mixing chamber 51, so that the slurries on both sides flow into the secondary mixing chamber 51 and then flow and mix against each other.

[0038] In one implementation, the inner diameter of the secondary mixing chamber 51 gradually decreases, and the inner diameter of the end of the secondary mixing chamber 51, i.e. the end of the secondary mixing chamber 51 away from the primary guide chamber 50, is smaller. The inner diameter of the end of the secondary mixing chamber 51 is the same as the inner diameter of the rear manifold 42, and the inner diameter of the beginning of the secondary mixing chamber 51 does not exceed twice the inner diameter of the rear manifold 42. Preferably, the inner diameter of the beginning of the secondary mixing chamber 51 is 1.4-1.6 times the inner diameter of the rear manifold 42.

[0039] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
