Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, and in particular to a pre-grouting construction device for highways. Background Technology

[0002] Pre-grouting for highways is a technique that involves injecting grout into the strata before subgrade construction to reinforce the surrounding rock and block fissures for water flow. This technique is commonly used to prevent water inrush in tunnels, ensure construction safety, and improve stratum stability. The highway tunnel engineering construction guidelines state that the grouting section length is generally 15 to 30 meters, the grouting material is usually cement grout with a water-cement ratio of 0.5:1 to 1:1, and the grouting pressure should be determined through field tests based on the rock properties and construction conditions.

[0003] The pre-grouting process typically includes the following steps:

[0004] S1. Drilling: Drill holes at predetermined locations according to design requirements. The drilling depth and angle must conform to design specifications. Key parameters, such as the development of rock fractures, must be recorded during the drilling process.

[0005] S2. Install the orifice pipe: After drilling, install the orifice pipe, ensuring it is secure and the external insertion angle is correct.

[0006] S3. Grouting and Grouting: Grout is prepared according to the selected grout mix ratio, and then injected into the pores of the soil and rock through a grouting pump. There are two grouting methods: single-liquid grouting and double-liquid grouting. Double-liquid grouting is further divided into single-liquid grouting and double-liquid grouting.

[0007] S4. Control grouting pressure and flow rate: During the grouting process, the grouting pressure and flow rate need to be adjusted according to the formation conditions to ensure that the grout can effectively fill the cracks and achieve the expected results.

[0008] S5. Curing and Inspection: After grouting is completed, the grouting area needs to be cured to ensure that the grout fully solidifies.

[0009] Grouting must be a continuous operation; otherwise, the waterproof mortar will settle, clog the pipeline, and affect the grouting effect. In existing highways, grouting is often carried out through a grouting station. However, during the pre-grouting process, due to terrain or the fact that some roadbeds have not yet been formed, large grouting equipment cannot reach the construction locations that need grouting, causing inconvenience to the grouting construction.

[0038] In this embodiment, preferably, the first feeding structure 31 is a tanker truck feeding port 311 set on the top of the storage silo 3, and the second feeding structure 32 is a manual feeding port 321 set on the top of the storage silo 3. The tanker truck feeding port 311 and the manual feeding port 321 can be one or two. The tanker truck feeding port 311 can be connected to the tanker truck that transports cement, so that the cement in the tanker truck can be transported to the storage silo 3.

[0039] In this embodiment, preferably, a material level detection sensor 35 is also included, which is installed on the storage silo 3 for monitoring the raw materials inside the storage silo 3. There are two material level detection sensors 35, which are respectively installed at the top and bottom of the storage silo 3, and the cement raw materials inside the storage silo 3 can be detected by the two material level detection sensors 35.

[0040] In this embodiment, preferably, the water inlet 41 includes a water inlet pipe, on which an electromagnetic flow meter 411 is installed. The electromagnetic flow meter 411 can measure the water delivered to the pulping machine 4. The pulping machine 4 is equipped with a weighing sensor 46, which can weigh the weight of the pulp in the pulping machine 4. Thus, by the cooperation of the material level detection sensor 35, the electromagnetic flow meter 411 and the weighing sensor 46, the water-cement ratio can be controlled.

[0041] In this embodiment, preferably, the positioning support assembly 12 includes a plurality of positioning support bodies 14, which are spaced apart at the bottom of the base 1. The positioning support bodies 14 have a supporting state and a moving state. When the positioning support body 14 is in the moving state, the roller component 111 is in contact with the ground and the positioning support body 14 is at a certain distance from the ground. Thus, the pre-grouting construction device can be moved to the designated position by the roller component 111. When the positioning support body 14 is in the supporting state, the positioning support body 14 is in contact with the ground, thereby fixing the pre-grouting construction device in the designated position, and then the grouting operation can be performed.

[0042] In this embodiment, preferably, the positioning support 14 includes a fixed support rod 141 and a movable support base 142. The fixed support rod 141 is hollow to form a motion cavity 143. A motion rod 144 is provided on the top of the movable support base 142 and is movably connected to the motion cavity 143. A telescopic drive unit 145 is provided in the motion cavity 143. A motion plate 146 is provided on the top of the motion rod 144 and is movably connected to the motion cavity 143. The motion plate 146 can move up and down within the motion cavity 143 under the drive of the telescopic drive unit 145. The telescopic drive unit 145 can be a cylinder and a piston rod connected to the cylinder. The telescopic drive unit 145 can also be other structures that can drive the motion plate 146 to move up and down. Thus, during use, the motion plate 146 can be moved up and down by the telescopic drive unit 145. The telescopic drive unit 145 drives the moving plate 146 and the moving rod 144 within the moving cavity 143, thereby switching the movable support seat 142 between a supporting state and a moving state. When the pre-grouting construction device needs to be moved, the telescopic drive unit 145 drives the moving plate 146 and the moving rod 144, causing the moving plate 146, the moving rod 144 and the movable support seat 142 to move upward, so that the movable support seat 142 leaves the ground and the roller 111 contacts the ground. Conversely, when the pre-grouting construction device moves to a suitable position, the telescopic drive unit 145 drives the moving plate 146 and the moving rod 144, causing the moving plate 146, the moving rod 144 and the movable support seat 142 to move downward until the movable support seat 142 contacts the ground, thereby fixing the pre-grouting construction device in the designated position.

[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.
