Description

Technical Field

[0001] The invention relates to the technical field of building pile foundation construction, and in particular to a grouting mechanism for building pile foundation. Background Art

[0002] The process of grouting in the building pile foundation mainly includes the following steps: Determine the quality and depth of the pile foundation: First, the quality and depth of the pile foundation need to be determined to determine the need for reinforcement and the specific operation method. This step is to ensure the effectiveness and safety of the reinforcement measures. Prepare materials and equipment: According to the measurement results, prepare the required grouting materials, such as cement, mortar, etc., and the corresponding grouting equipment, such as grouting pumps, etc. Selecting the right materials and equipment is the key to ensuring the grouting effect. Clean the surface of the pile foundation: Use cleaning equipment to clean the soil, dust and other impurities on the surface of the pile foundation to ensure that the material can fully contact the pile foundation. This step is to ensure that the grouting material can be evenly distributed on the pile foundation and improve the reinforcement effect. Drilling grouting: According to the situation of the pile foundation, drill holes on the surface of the pile foundation and inject the grouting material into it. The depth and number of holes are determined according to the specific situation to ensure that the grouting material can penetrate into all parts of the pile foundation. Grouting injection: Use a grouting pump to inject the pre-prepared grouting material into the drilled hole until the hole is filled and the slurry is evenly distributed around the pile foundation. This step is the core of the entire grouting process and directly affects the reinforcement effect. Surface repair: After the grouting material is fully solidified, the surface of the pile foundation is repaired to enhance the durability and stability of the pile foundation. This step is to ensure that the reinforced pile foundation can withstand a greater load and improve the stability of the overall structure. Through the above steps, the building pile foundation can be effectively grouted, thereby improving the bearing capacity and stability of the pile foundation and enhancing the safety of the building.

[0003] The existing building pile foundation needs to be grouted during the construction process. When the existing grouting mechanism mixes the slurry, the cement raw material and water are usually added into the mixing tank at the same time for stirring. After stirring, the stirred slurry is transported to the building pile foundation through a delivery pump. However, when the slurry is mixed, the cement is not stirred sufficiently when the cement and water are added at the same time, resulting in some dry cement in the slurry and a large number of bubbles. When the insufficiently stirred slurry is transported to the pile foundation, pores will appear in the pile foundation, which will reduce the density of the building pile foundation, greatly reduce the quality of the pile foundation, and bring certain adverse effects to the actual use. Therefore, it is necessary to improve it. To this end, we propose a grouting mechanism for building pile foundations to facilitate filtering stirring when injecting the slurry, avoid the presence of dry cement in the slurry, and reduce the generation of bubbles during mixing, thereby reducing the bubbles in the pile foundation and improving the quality of the pile foundation. Summary of the invention

[0004] In response to the problems in the prior art, the present invention provides a grouting mechanism for building pile foundations, which is convenient for filtering and stirring the slurry when injecting it, avoiding the presence of dry cement in the slurry and reducing the generation of bubbles during mixing, thereby reducing the bubbles in the pile foundation and improving the quality of the pile foundation.

[0005] The technical solution adopted by the invention to solve its technical problem is a grouting mechanism for building pile foundation, including a bearing plate and a bracket, a mixing mechanism is installed at the top of the bearing plate, and the mixing mechanism is composed of a mixing tank, a concave frame, a motor A, a rotating shaft, a defoaming rod, a stirring blade A, a honeycomb hole and a gear A. A mixing tank is installed at the top of the bearing plate, a concave frame is installed at the tank wall of the mixing tank by bolts, a motor A is installed at the top of the concave frame by bolts, a rotating shaft is installed at the output end of the motor A, a plurality of groups of stirring blades A for mixing slurry are welded at the shaft wall of the rotating shaft, a defoaming rod is welded between the plurality of groups of stirring blades A, a gear A is installed at the shaft wall of the rotating shaft, and a honeycomb hole for filtering slurry is opened at the tank wall of the mixing tank;

A vertical rod is rotatably connected to the inner wall of the semi-cylinder. A plurality of stirring blades B for stirring the filtered slurry are welded on the rod wall of the vertical rod. A gear B is installed on the rod wall of the vertical rod, and the gear B is connected to the gear A through a gear belt.

[0007] By adopting the above technical scheme, when the raw materials for grouting the building pile foundation are mixed, since a mixing mechanism is installed at the top of the bearing plate, the mixing mechanism is composed of a mixing tank, a concave frame, a motor A, a rotating shaft, a defoaming rod, a stirring blade A, a honeycomb hole and a gear A. After the cement raw material and some materials such as water are added into the mixing tank, since a concave frame is installed on the tank wall of the mixing tank by bolts, the motor A at the concave frame is controlled by a controller so that the motor A drives the rotating shaft at its output end to rotate.

The stirring blades A are attached to the inner wall of the mixing tank to rotate and stir, and the defoaming rod rotates in the mixing tank to eliminate bubbles in the slurry.

[0008] During the grouting, since the mixing tank wall is provided with honeycomb holes, the stirring blade A is attached to the mixing tank and rotates, so that the mixed cement slurry is discharged through the honeycomb holes. Since a semi-cylinder is welded on the mixing tank wall, the semi-cylinder is located on one side of the honeycomb hole, so that the mixed cement slurry enters the semi-cylinder through the honeycomb hole, so that the dry cement that is not completely mixed enters the semi-cylinder. Since the semi-cylinder inner wall is rotatably connected to the vertical rod, a gear B is installed on the rod wall of the vertical rod, and the gear B is connected to the gear A at the rotating shaft through a gear belt, so that the rotation of the gear A drives the gear B to rotate, so that the vertical rod is driven to rotate in the semi-cylinder. Since several groups of stirring blades B are welded on the rod wall of the vertical rod, the stirring blade B stirs the slurry twice in the semi-cylinder, removes the bubbles in the slurry once, and realizes uniform mixing of the slurry. Then the slurry is extracted and transported to the building pile foundation through the conveying pump through the conduit, so as to reduce the bubbles in the pile foundation and improve the quality of the pile foundation.

After the feeding pipe is supported by welding the bracket, the other end of the discharge pipe is located at the top of the mixing tank. Since the funnel head is welded on the wall of the feeding pipe, the cement raw material enters the feeding pipe through the funnel head, and then the controller controls the motor B so that the motor B drives the shear screw at its output end to rotate in the feeding pipe, so that the cement is transported between the shear screw and the feeding pipe, so that the cement raw material is transported to the discharge pipe, and then discharged into the mixing tank through the other end of the discharge pipe, which is convenient for personnel to feed the cement raw material.

[0013] Specifically, the other end of the discharge pipe is located at the top of the mixing tank.

[0014] By adopting the above technical solution, after the cement raw material is transported to the discharge pipe through the feeding pipe, the other end of the discharge pipe is located at the top of the mixing tank, thereby transporting the cement raw material to the mixing tank.

[0016] By adopting the above technical scheme, when the mixed slurry is transported to the building pile foundation for grouting, since a delivery pump is installed at the top of the bearing plate, the delivery pump is controlled by a controller to operate the delivery pump. After the delivery pump extracts the mixed slurry in the semi-cylinder through the conduit, the pressure is displayed by the pressure gauge on the delivery cylinder wall of the delivery pump. After the personnel connect the external grouting pipe with the delivery valve pipe at the discharge port of the delivery pump, the personnel open the delivery valve pipe to allow the slurry to be grouted into the building pile foundation through the external grouting pipe.

Since a semi-cylinder is welded on the mixing tank wall, the semi-cylinder is located on one side of the honeycomb hole, so that the mixed cement slurry enters the semi-cylinder through the honeycomb hole, so that the dry cement that is not completely mixed enters the semi-cylinder. Since the semi-cylinder inner wall is rotatably connected to the vertical rod, a gear B is installed on the rod wall of the vertical rod, and the gear B is connected to the gear A at the rotating shaft through a gear belt, so that the rotation of the gear A drives the gear B to rotate, so that the vertical rod is driven to rotate in the semi-cylinder. Since several groups of stirring blades B are welded on the rod wall of the vertical rod, the stirring blade B stirs the slurry twice in the semi-cylinder, removes the bubbles in the slurry once, and realizes uniform mixing of the slurry. Then the slurry is extracted and transported to the building pile foundation through the conveying pump through the conduit, so as to reduce the bubbles in the pile foundation and improve the quality of the pile foundation.

[0054] When the mixed slurry is transported to the building pile foundation for grouting, since a delivery pump 11 is installed at the top of the bearing plate 1, the delivery pump 11 is controlled by the controller 8 to operate. After the delivery pump 11 extracts the mixed slurry in the semi-cylinder 3 through the conduit, the pressure is displayed by the pressure gauge 12 on the cylinder wall of the delivery pump 11. After the personnel connect the external grouting pipe with the delivery valve pipe 10 at the discharge port of the delivery pump 11, the personnel open the delivery valve pipe 10 to allow the slurry to be grouted into the building pile foundation through the external grouting pipe.
