Substrate grouting reinforcement repair construction method, recently found that many people do not know much about this, this article will briefly introduce the relevant content:
The foundation grouting reinforcement repair construction method is a commonly used civil engineering technology to repair and strengthen the cracks, leakage or looseness encountered in underground structures (such as foundations, pits, basements, etc.). The construction process of this method includes survey, design, and reinforcement methods, each of which is explained in depth below.
1. Survey. The survey stage of the foundation grouting reinforcement repair construction is to fully understand the specific condition of the construction object, so as to determine the construction plan and reinforcement method. The main contents of the survey include:
1. The size and shape of the underground structure: measure the length, width, height and other dimensions of the underground structure, and record it.
2.Damage to underground structures: Detect cracks, leaks, loosening and other problems in underground structures to determine the focus of repair and the area of reinforcement.
3.Soil condition of underground structure: Detect the soil condition around the underground structure, including soil quality, water content, hardness and other factors, in order to determine the selection of grouting materials and grouting methods.
4.Condition of Adjacent Buildings: Examine the structural condition of nearby buildings to ensure that they will not be adversely affected during construction.
Second, design. Based on the survey results, the designer will develop a detailed construction plan, including the type of grouting material, the selection of grouting equipment, the layout of grouting holes, the setting of grouting parameters, etc. The main contents of the design include:
1. Selection of grouting materials: according to the nature of the soil and the degree of damage, select the appropriate grouting materials, such as cement slurry, polymer slurry, etc.
2.Selection of grouting equipment: According to the size and shape of the construction object, select the appropriate grouting equipment, such as grouting machine, pump, etc.
3.Arrangement of grouting holes: According to the damage and load characteristics of the underground structure, the arrangement of the grouting holes is determined to ensure that the grouting effect is uniform and durable.
4.Setting of grouting parameters: According to the characteristics of the grouting material and the construction requirements, set the pressure, flow, concentration of grout and other parameters to ensure the construction effect.
3. Reinforcement method.
The method of substrate grouting reinforcement and repair mainly includes grouting construction and reinforcement measures.
1. Grouting construction: use grouting equipment to inject grouting materials into the pre-arranged grouting holes, fill the voids of the damaged parts, and enhance the bearing capacity and stability of the underground structure. The process of grouting construction needs to strictly control the grouting parameters to ensure that the grouting is uniform and full.
2.Reinforcement measures: In the process of grouting reinforcement, some measures may need to be taken to enhance the reinforcement effect, such as setting reinforcement reinforcement, burying prestressed anchors, etc. These reinforcements need to be designed and constructed on a case-by-case basis.
The investigation, design and reinforcement methods of foundation grouting reinforcement and repair construction methods are a process that connects with each other. Through comprehensive investigation, scientific design and strict reinforcement construction, the underground structure can be effectively repaired and reinforced, and its bearing capacity and stability can be improved.
