Description

Technical Field

[0001] This utility model relates to the field of grouting technology in water conservancy projects, and more specifically, to a grouting device for water conservancy project construction. Background Technology

[0002] Grouting devices in water conservancy construction are an important engineering technology used to reinforce foundations, prevent leakage, and repair structural defects. They improve the physical and mechanical properties of soil, rock cracks, or structures by injecting specific grout materials (such as cement grout, chemical grout, etc.) into the voids inside the structure.

[0003] When using existing grouting equipment for water conservancy projects, the grouting truck is moved to the side of the water conservancy project to be grouted by pushing the handle. Then, the grouting pipe is inserted into the drilled hole to ensure that it is stable and in the correct position. Then, the water pump is started to transport the grouting liquid in the grouting tank to the drilled hole through the grouting pipe, thereby completing the grouting work.

[0004] In practical applications, existing technologies can easily lead to stratum fracturing or uneven distribution due to excessively fast or slow grout flow during the grouting process. At the same time, a large number of air bubbles are easily generated during the mixing process of the grout. If the air bubbles are not eliminated in time, they can easily affect the grouting effect and quality of subsequent water conservancy engineering construction. Therefore, a grouting device for water conservancy engineering construction is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a grouting device for water conservancy engineering construction. It uses a flow meter on the surface of the grouting pipe to monitor and precisely control the flow rate of the grout in real time, ensuring that the grout is injected into the stratum at an appropriate rate. This avoids problems such as stratum fracturing or uneven distribution caused by excessively fast or slow flow rates. Simultaneously, a pressure detector can detect pressure changes during the grouting process in real time, promptly identifying abnormalities. By adjusting the speed or pressure of the water pump, the safety and effectiveness of the grouting operation are ensured, thereby reducing sudden impacts on the stratum, lowering the risk of stratum fracturing, and improving the safety and stability of the grouting process.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A grouting device for water conservancy engineering construction includes a grouting truck and casters. Multiple casters are fixedly connected to the bottom of the grouting truck, and a grouting tank is fixedly connected to the upper surface of the grouting truck. A precision grouting component is installed on the outer surface of the grouting tank, and a mixing and defoaming component is installed inside the grouting tank. The precision grouting component includes a grouting pipe fixedly connected inside the grouting tank. One end of the grouting pipe is inserted into the outer surface of the grouting tank and fixedly connected to a flow meter. A pressure detector is installed on the outer surface of the grouting pipe. The mixing and defoaming component includes a connecting plate fixedly connected to the upper surface of the grouting tank. A motor is fixedly connected to the bottom of the connecting plate, and a mixing rod is fixedly connected to the output shaft end of the motor. One end of the mixing rod is rotatably inserted into the outer surface of the grouting tank and connected to multiple mixing rods. Multiple defoaming needles are fixedly connected to the outer surface of the mixing rods.

[0010] Furthermore, a connecting block is installed on the outer surface of the grouting tank, and the outer surface of the grouting pipe is connected to the interior of the connecting block. The grouting pipe is made of a spring hose.

[0011] Furthermore, a feed pipe and a discharge pipe are respectively installed on the upper surface and bottom of the grouting tank, and a sealing cover is movably connected to the outer surface of the feed pipe and the discharge pipe. A push rod is fixedly connected to the side of the grouting vehicle.

[0012] Furthermore, the defoaming needle is made of stainless steel, and its outer surface is coated with a corrosion-resistant coating.

[0013] Furthermore, one end of the mixing rod is connected to a scraper, which abuts against the inner cavity of the grouting tank.

[0014] Furthermore, a guide agent tank is connected to the outer surface of the grouting tank via a support block, and a guide agent tube is connected inside the guide agent tank.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This scheme can monitor and precisely control the flow rate of the grout in real time through the flow meter on the surface of the grouting pipe, ensuring that the grout is injected into the formation at an appropriate rate, avoiding the formation rupture or uneven distribution caused by the flow rate being too fast or too slow. At the same time, the pressure detector can detect the pressure change during the grouting process in real time, detect abnormalities in time, and ensure the safety and effectiveness of the grouting operation by adjusting the speed or pressure of the water pump, thereby reducing the sudden impact on the formation, reducing the risk of formation rupture, and improving the safety and stability of grouting.

[0018] (2) The grouting pipe is made of spring hose and can be flexibly adjusted in length and angle according to actual construction needs, which increases the flexibility of operation and the ability to adapt to different construction environments. At the same time, through the cooperation of the guide agent tank, guide agent pipe and flow meter II, a precise guide agent can be added into the grouting tank, which can adjust the viscosity and fluidity of the grouting liquid, making it easier to pass through complex geological structures or small cracks. Meanwhile, the guide agent helps to reduce the resistance encountered by the grouting liquid when passing through narrow channels, making the grouting process smoother and reducing the risk of blockage.

[0019] (3) This solution uses a motor-driven mixing rod and mixing bar to fully and evenly mix the grouting material and guiding agent in the grouting tank, ensuring that the quality of each batch of grout is consistent and improving the grouting effect. During the mixing process, the defoaming needle can effectively puncture the generated air bubbles, reducing the impact of air bubbles on the grouting quality. At the same time, the scraper can clean the inner wall of the grouting tank, preventing material adhesion and keeping the tank clean, thereby reducing manual intervention and improving work efficiency and construction safety.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present utility model. This embodiment provides a grouting device for water conservancy engineering construction, including a grouting vehicle 1 and universal wheels 101. Multiple universal wheels 101 are fixedly connected to the bottom of the grouting vehicle 1, and a grouting tank 102 is fixedly connected to the upper surface of the grouting vehicle 1. A precision grouting component 2 is installed on the outer surface of the grouting tank 102.

[0031] Specifically, the precision grouting component 2 includes a grouting pipe 201 fixedly connected inside the grouting tank 102. One end of the grouting pipe 201 is inserted into the outer surface of the grouting tank 102 and fixedly connected to a flow meter 202. A pressure detector 203 is installed on the outer surface of the grouting pipe 201. A connecting block 204 is installed on the outer surface of the grouting tank 102. The outer surface of the grouting pipe 201 is connected to the interior of the connecting block 204. The grouting pipe 201 is made of a spring hose. The upper surface of the grouting tank 102 and... The bottom is equipped with a feed pipe and a discharge pipe, and the outer surfaces of the feed pipe and the discharge pipe are movably connected with sealing caps. A push rod is fixedly connected to the side of the grouting vehicle 1. The outer surface of the grouting tank 102 is connected to the guide agent tank 4 through a support block. The inside of the guide agent tank 4 is connected to the guide agent pipe 401. One end of the guide agent pipe 401 is connected to the inside of the feed pipe. A water pump is installed on the outer surface of the guide agent pipe 401 and the grouting pipe 201. A flow meter 402 is installed on the outer surface of the guide agent pipe 401.

[0032] Furthermore, one end of the grouting pipe 201 is inserted into a pre-drilled hole, and the water pump on the surface of the grouting pipe 201 is started to deliver the grouting liquid containing the guiding agent from the grouting tank 102 through the grouting pipe 201 to the target location. The data is monitored in real time by the flow meter 202 to ensure that the grouting liquid is injected at an appropriate flow rate. The pressure change during the grouting process is monitored by the pressure detector 203, and the water pump speed or pressure is adjusted as necessary to ensure the grouting effect.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment. The grouting tank 102 is equipped with a mixing and defoaming component 3.

[0035] Specifically, the mixing and defoaming component 3 includes a connecting plate fixedly connected to the upper surface of the grouting tank 102. A motor 301 is fixedly connected to the bottom of the connecting plate. A mixing rod 302 is fixedly connected to the output shaft end of the motor 301. One end of the mixing rod 302 can be rotatably inserted into the outer surface of the grouting tank 102 and connected to multiple mixing rods 303. Multiple defoaming needles 304 are fixedly connected to the outer surface of the mixing rods 303. The defoaming needles 304 are made of stainless steel and coated with a layer of corrosion-resistant coating. One end of the mixing rod 303 is connected to a scraper 305, which abuts against the inner cavity of the grouting tank 102.

[0036] Furthermore, the water pump on the surface of the guide agent tube 401 is activated to extract the guide agent from the guide agent tank 4 and deliver it to the feed pipe through the guide agent tube 401. The amount of guide agent added is precisely controlled by the flow meter 402. The motor 301 is started to drive the mixing rod 302 to rotate. When the mixing rod 302 rotates, it will drive multiple mixing rods 303 to rotate, so as to fully mix the grouting material and guide agent in the grouting tank 102. During the mixing process, the defoaming needle 304 will puncture the generated air bubbles. At the same time, when the mixing rod 303 rotates, it will drive the scraper 305 to scrape off the grouting liquid adhering to the grouting tank 102.

[0037] Working principle: In use, first prepare the required grouting material and guiding agent. Inject the guiding agent into the guiding agent tank 4 through the injection pipe installed above the guiding agent tank 4. After injection, close the injection pipe, then open the sealing cap on the feed pipe and pour the grouting material into the grouting tank 102. Simultaneously, start the water pump on the surface of the guiding agent pipe 401 to draw the guiding agent from the guiding agent tank 4 and deliver it to the feed pipe through the guiding agent pipe 401. The amount of guiding agent added is precisely controlled by the flow meter 402. (Since the specific installation method, circuit connection method, oil circuit connection method, and control method of the flow meter 402 are all conventional designs, their specific structure and working principle are beyond the comprehension of those skilled in the art.) (The existing technology is well-known and will not be elaborated on here.) Ensure the correct ratio of the grouting material to the grouting material. After injection, use a push rod to push the grouting cart 1 and move it to the position where grouting is required using casters 101. Then, start the motor 301 to drive the mixing rod 302 to rotate. When the mixing rod 302 rotates, it will drive multiple mixing rods 303 to rotate, so as to fully mix the grouting material and the guiding agent in the grouting tank 102. During the mixing process, the defoaming needle 304 will puncture the generated air bubbles to reduce the impact of air bubbles on the grouting quality. At the same time, when the mixing rods 303 rotate, they will drive the scraper 305 to scrape off the grouting liquid adhering to the grouting tank 102 to prevent material adhesion.

[0038] When grouting is required, one end of the grouting pipe 201 is inserted into a pre-drilled hole. Since the grouting pipe 201 is made of a spring hose, its length and angle can be flexibly adjusted according to actual needs. Then, the water pump on the surface of the grouting pipe 201 is started to deliver the grouting liquid containing the guiding agent from the grouting tank 102 through the grouting pipe 201 to the target location. The data is monitored in real time by the flow meter 202 to ensure that the grouting liquid is injected at an appropriate flow rate. The pressure change during the grouting process is monitored by the pressure detector 203. If necessary, the water pump speed or pressure is adjusted (since the specific installation method, circuit connection method, oil circuit connection method and control method of the flow meter 202 and pressure detector 203 are all conventional designs, their specific structure and working principle are existing technologies well known to those skilled in the art, and will not be elaborated on here) to ensure the grouting effect. The flow rate during grouting can be gradually increased to reduce the sudden impact on the stratum and reduce the risk of stratum fracturing. After grouting is completed, the water pump and motor 301 are turned off, the grouting operation is stopped, the grouting pipe 201 is removed, and the construction site is cleaned up.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
