[0002] In some high-speed rail projects, the four power houses and their attached walls are plain walls. The masonry quality of the plain walls will directly affect the overall effect of the house attachments. It was found during construction that the main reason for the poor quality of the plain walls is the overall grouting process in the later stage. The existing technology uses wire to dig out the joints and uses a grouting shovel and a trowel to cooperate with a support plate to fill the joints. Professional workers are required to carry out the grouting work. Not only is the construction quality of the plain walls poor and the construction efficiency is low, but there is also a problem of material waste. The waste of building materials such as cement and sand will also cause environmental pollution. Therefore, an integrated device for digging, grouting and grouting of plain walls is urgently needed to improve the overall construction quality of the walls, speed up the construction progress, and save construction costs.

DETAILED DESCRIPTION

[0018] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an integrated device for hollowing, grouting and grouting of a dry wall of the utility model in conjunction with the accompanying drawings.

[0019] like Figure 1~Figure 5As shown, an integrated device for hollowing and grouting joints of a clear water wall comprises a grouting pipe 1, a spiral conveying rod 2 is coaxially arranged in the grouting pipe 1, a spiral conveying plate is arranged on the rod body of the spiral conveying rod 2, an opening is arranged above the grouting pipe 1 and connected to a grouting bin 3, a vertical grip 4 is fixedly connected below the grouting pipe 1, a conical grouting gun nozzle 5 for grouting is arranged at the front end of the grouting pipe 1, a bearing 6 is arranged at the rear end of the grouting pipe 1 to connect to the spiral conveying rod 2, the spiral conveying rod 2 is connected to the output end of a hand drill 7, and the grouting The left and right sides of the gun nozzle 5 are respectively provided with a grooving piece 8 for grooving and cleaning the mortar joints and a movable grouting ball 9 for grouting and beautifying the mortar joints. The grooving piece 8 includes a connecting part 81 connected to the grouting gun nozzle 5, and the end of the connecting part 81 extends forward and is successively provided with a discharge part 82 and a cleaning part 83. The discharge part 82 is provided with a first cavity at an opening on one side away from the grouting gun nozzle 5, and discharge ports are provided on the upper and lower sides of the first cavity. The front end of the cleaning part 83 is closed, and a second cavity connected to the first cavity is provided inside it.

[0020] The slurry storage bin 3 is used to store mortar materials and introduce them into the slurry delivery pipe 1. The hand drill 7 is connected to the spiral conveying rod 2 through the bearing 6 and is on the same central axis. The spiral conveying rod 2 plays the role of conveying mortar materials, stabilizing the device, and transmitting power. The bearing 6 plays the role of transmitting force and positioning, and ensures the stability of the device position during the rapid rotation of the hand drill 7. The hand drill 7, as a power component, also has a fixing function, so that the device can continue to work stably after the grouting operation begins. The vertical handle 4 is located in the lower center of the slurry storage bin 3. The vertical handle 4 provides support and plays the role of stabilizing the device. The grooving piece 8 can first clean up the excess mortar in the mortar joint to make the depth of the mortar joint uniform. The grouting gun nozzle 5 can evenly inject the mortar conveyed by the spiral conveying rod 2 into the mortar joint to complete the grouting construction. The movable grouting ball 9 plays the role of grouting and grouting to ensure the construction is beautiful and neat.

[0021] In this embodiment, the grouting gun nozzle 5 can be rotated, and the grouting and grouting construction of different vertical and horizontal joints can be carried out by rotating the grouting gun nozzle 5. The grouting member 8 arranged on the outside of the grouting gun nozzle 5 has a cleaning portion 83 that is 5 mm longer than the top of the grouting gun nozzle 5. The cleaning portion 83 has an arc-shaped side wall, and the arc-shaped side wall is tangentially connected to the upper and lower side walls of the discharge portion 82. The cleaning portion 83 is used to perform the grouting work, that is, to remove the excess mortar in the mortar joint to make the depth of the mortar joint uniform, and the excess mortar is introduced from the second cavity into the first cavity and discharged from the discharge port, thereby facilitating the grouting construction.

[0022] The movable grouting ball 9 arranged outside the grouting gun nozzle 5 is 10 mm longer than the top of the grouting gun nozzle 5, the rear of the movable grouting ball 9 is fixedly connected to the fixed rod, the rear end of the fixed rod is movably connected to the grouting gun nozzle 5, and a tension spring 10 is connected between the rod body of the fixed rod and the grouting gun nozzle 5 to provide a tensile force to constrain the movable grouting ball 9 to be close to the wall seam for grouting and grouting. Specifically, a mounting base 11 is arranged outside the grouting gun nozzle 5, the mounting base 11 is composed of two parallel plates, the rear end of the fixed rod is pivotally connected to the mounting base 11, and the two ends of the tension spring 10 are respectively embedded in the spring groove arranged on one side of the grouting gun nozzle 5 and the spring groove arranged in the middle of the fixed rod.

[0023] When in use, the rear end of the spiral conveying rod 2 is inserted into the hand drill 7. Before grouting, the device is checked to check whether each component is operating normally. After it is operating normally, the filling and grouting can be performed. Before grouting, pre-grouting should be performed to check whether the grouting amount is uniform. The formal grouting can be performed after the grouting amount is uniform. Before grouting and grouting, hold the vertical handle 4 by hand to make the grouting process as a whole stable and orderly. During the preparation work, the grouting gun nozzle 5 is brought about 5mm close to the wall seam so that the seam-cutting piece 8 is close to the mortar seam, and then the hand drill 7 is started to accelerate the rotation of the bearing 6 and the spiral conveying rod 2. When moving the device to work, the excess mortar in the mortar seam is first cleaned through the seam-cutting piece 8 in front of the moving direction of the grouting gun nozzle 5 to make the depth of the mortar seam uniform, so that the grouting gun nozzle 5 can inject the grouting mortar into the mortar seam. While the mortar is injected into the mortar seam of the wall, the device is moved smoothly along the mortar seam, and the movable grouting ball 9 behind the moving direction of the grouting gun nozzle 5 is used to perform the grouting and grouting closing work during the movement of the device.

[0024] The device has low processing and manufacturing costs, is easy to carry and fix, and is convenient and quick to construct. It has the characteristics of high one-time success rate and high construction efficiency, and can effectively avoid the problem of increased construction costs caused by rework. It also greatly reduces the demand for professional jobs. Workers only need simple training and guidance on site to be competent for this job, which greatly saves labor costs. The device can also avoid the increase in costs caused by material waste. The use of this device can directly reduce the use of mortar, which is of great significance in green construction such as environmental protection and energy conservation and emission reduction.

[0025] This device has achieved remarkable results in practical application. It avoids material waste, reduces the secondary rework rate to almost zero, saves labor costs, has high construction efficiency, and has good social, economic and environmental protection benefits. It provides reliable theoretical support and valuable construction experience for other similar wall constructions, and plays a positive role in reducing costs and increasing efficiency in the building construction industry.
