Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to a method for constructing prefabricated concrete walls. Background Technology

[0002] The construction of concrete walls is inseparable from the selection and use of concrete materials. Concrete is a building material composed of cement, aggregates, water, and admixtures mixed in a certain proportion. In concrete wall construction, it is necessary to understand the concrete mix proportions, strength, and other performance indicators, as well as the construction techniques and conditions. Concrete wall construction requires structural design, including the wall's height, thickness, and the location of openings. The structural design of the wall must consider factors such as load-bearing capacity, seismic performance, and temperature deformation to ensure the safety and stability of the wall during use. Formwork is often used in concrete wall construction to fix and shape the concrete. Formwork technology includes the selection and installation of formwork, the design and construction of support systems, and the removal and recycling of formwork. The quality and installation accuracy of the formwork directly affect the quality of the wall's formation. The construction of concrete walls requires the selection of appropriate construction techniques based on specific circumstances. This includes the processes of concrete pouring, vibration, and curing. A reasonable selection of construction techniques can improve construction efficiency and ensure the quality and strength of the wall. Concrete wall construction requires the use of a series of construction equipment and tools, such as concrete mixers, cranes, formwork support systems, electric vibrators, and levels. Safety management and quality control are crucial in concrete wall construction. Construction workers must adhere to relevant safety operating procedures to ensure site safety and personnel health. Simultaneously, rigorous quality control is essential, including quality inspection of concrete materials and verification of wall dimensions and flatness, to ensure the wall quality meets design requirements.

[0003] However, the overall construction of concrete walls will result in a large construction site occupation and low construction efficiency. Large-area concrete pouring will lead to a long drying time for concrete walls and a complicated curing process. Summary of the Invention

[0004] In view of this, the present invention provides a prefabricated concrete wall construction method, which can solve the problems of large construction site occupation and low construction efficiency caused by the overall construction of concrete walls, as well as the long drying time and complicated curing process caused by large-area concrete pouring.

[0005] This invention is implemented as follows:

[0006] This invention provides a method for constructing prefabricated concrete walls, comprising the following steps:

[0007] S10: Measure and mark the position and dimensions of the wall, and measure the distance and angle between the surrounding objects and the wall;

[0008] S20: Construction workers construct a three-dimensional model based on the dimensions of the wall and its distance from surrounding objects, and then divide the wall according to the three-dimensional model;

[0009] S30: Construction workers construct the wall components according to the dimensions divided by the three-dimensional model;

[0010] S40: Excavate a foundation pit at the construction site of the wall and fill it with base material;

[0011] S50: Fix the wall components in the foundation pit and pour a concrete foundation;

[0012] S60: Connect and fix the wall components to the components in the foundation pit in sequence;

[0013] S70: Use a level to adjust the wall panels horizontally and vertically;

[0014] S80: After the wall panels are installed, the gaps between and around the wall panels are filled with concrete grout to increase the strength and sealing of the wall.

[0015] S90: After the wall panel installation and fixing are completed, subsequent processing work is carried out.

[0016] The technical advantages of the prefabricated concrete wall construction method provided by this invention are as follows: The method involves measuring and marking the wall's position and dimensions, and measuring the distances and angles between the wall and surrounding objects; constructing a three-dimensional model based on the wall's dimensions and distances to surrounding objects, and then segmenting the wall according to the three-dimensional model; constructing wall components based on the dimensions of the segmented three-dimensional model; excavating a foundation pit at the construction site of the wall and filling it with base material; fixing the wall components in the foundation pit and pouring a concrete foundation; sequentially connecting and fixing the wall components to the components in the foundation pit; using a level to adjust the wall panels horizontally and vertically; after the wall panels are installed, filling the gaps between and around the wall panels with concrete grout to increase the wall's strength and sealing; and performing subsequent processing after the wall panels are installed and fixed. This method solves the problems of large construction site occupation and low construction efficiency caused by overall concrete wall construction, as well as the long drying time and complex curing process resulting from large-area concrete pouring.

[0017] Based on the above technical solution, the prefabricated concrete wall construction method of the present invention can be further improved as follows:

[0018] The construction workers construct a three-dimensional model of the wall based on its dimensions and distances from surrounding objects. The specific steps for dividing the wall using this three-dimensional model include:

[0019] The first step involves the construction workers using SolidWorks software to build a 3D model of the wall based on its dimensions and distance from surrounding objects. The 3D model of the wall is then scanned to generate a point cloud map.

[0020] The second step is for the construction workers to voxelize the initial point cloud to obtain multiple voxel cubes;

[0021] The third step involves the construction personnel selecting any of the aforementioned voxel cubes as the center cube, calculating the fitting plane normal vector in each adjacent cube adjacent to the center cube, and calculating the angle between each fitting plane normal vector and the center fitting plane normal vector of the center cube. When the angle is less than a set angle threshold, it is determined that the center cube and the adjacent cube can be fitted to form a cube fitting plane, and the preliminary point cloud of the cube fitting plane is determined.

[0022] The fourth step involves the construction personnel projecting the three-dimensional data of the cube fitting plane onto the cube fitting plane to form two-dimensional data. The two-dimensional data is then divided into grids, and the number of points in each grid is compared with a set point count threshold. Grids with a number of points greater than the threshold are numbered as new data points. These new data points are then numbered and classified based on a clustering algorithm to obtain the finely segmented plane of the cube fitting plane.

[0023] Fifth, the construction personnel repeat the steps of the third and fourth steps until the initial point cloud is traversed, all the fine segmentation planes are obtained, and the over-segmented planes in the fine segmentation planes are optimized;

[0048] The method for determining the treatment based on the soil conditions at the bottom of the foundation pit includes:

[0049] For deeper foundation pits, the bearing capacity can be improved by reinforcing the fences and reinforcing the concrete pouring.

[0050] For shallower foundation pits, high-pressure jet grouting and cement mortar grouting are used to increase the bearing capacity.
