Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a grouting device and a repair method thereof for protecting and repairing buildings. Background Art

[0002] Because the protected buildings not only need to be repaired in their own structures, but also need to develop their underground spaces. Therefore, the protected buildings need to be moved and repaired. The common method of repairing and constructing protected buildings is to move the protected buildings to the intermediate site, where the protected buildings are temporarily placed. After the underground structure is completed, the protected buildings are moved back to their original locations. After they are moved back to their original locations, repairs are carried out on site. The redundant structures of the protected buildings are removed and the outer walls are retained. Then, the permanent structural columns, beams, and slabs of the internal frame structure are constructed to meet the structural support requirements of the protected buildings. Finally, the facade repairs and decoration are carried out.

[0003] After the permanent column reinforcement is connected to the grouting sleeve in the basement top plate and grouting is performed, the connection between the protection building and the basement top plate is realized, and the grouting equipment is required. Since the grouting equipment is large and the distance between the protection buildings is small, it does not meet the transportation requirements of large machinery and large materials, which has a great impact on the project safety, progress and construction cost. Therefore, a concrete paving pump device is usually used to transport the concrete output by the pumping system to the corners of the construction site.

[0004] When the concrete paving pump device is used, it is equipped with a distributing device to achieve accurate laying of concrete, improve construction efficiency and project quality. In the process of using the existing concrete distributing machine, it is generally required that the staff assist the down-feeding pipe to carry out fixed-point and quantitative discharging according to the situation of the concrete distributing area, so as to meet the needs of different discharging amounts in different areas, ensure sufficient irrigation of concrete, and thus improve the quality of construction. However, this method not only requires manpower, but also has low construction efficiency, is prone to cause safety accidents, and is inconvenient to use. It is necessary to control the output of concrete according to demand. For example, when the concrete distributing machine grouts the concrete, and the grouting place is laid to a suitable height, the grouting work cannot be stopped immediately, and leakage will occur, which not only affects the laying of the grouting place, but also causes waste of concrete. At the same time, the down-feeding pipe of the concrete distributing machine is heavy, and the staff needs to spend a lot of effort to move it, which increases the intensity of the grouting work and is inconvenient for the staff to use. Therefore, a grouting device and a repair method for protecting and repairing buildings are proposed to solve the above-mentioned problems. Summary of the invention

This step requires precise control of translation speed, direction and stability to ensure that the building is not damaged during the translation process; S2-2, Temporary support: Set up temporary support structures under the protected building, such as steel columns, jacks, etc., to bear the weight of the building and maintain stability. The support structure must be accurately calculated and designed to ensure its bearing capacity and stability; S3: Repair and construction S3-1. Foundation treatment: Strengthen or rebuild the foundation below the protected building to improve the stability and bearing capacity of the building. At the same time, reserve structural connectors such as grouting sleeves on the top plate of the basement. Insert the permanent column steel bars into the reserved grouting sleeves. Finally, use the grouting equipment and the grouting feed pipe (1) to inject grout into the grouting sleeves to achieve the installation of the protected building. S3-2, Structural repair: inspect and repair the structural components of the protected buildings, such as reinforcing beams and columns, repairing walls, etc. Severely damaged structural components need to be replaced or rebuilt; S3-3. External facade repair: Use the same materials, craftsmanship and style as the original building to repair the external facade. For damaged parts such as missing parts and weathering parts, use patching and inlaying methods to repair them.
