Many people do not know much about the requirements for the reinforcement of dense grouting foundations, and here is an introduction related to this prepared for you, and interested family and friends can read and collect it.
The construction requirements of dense grouting foundation reinforcement refer to the use of dense grouting to strengthen the foundation in the foundation reinforcement project. The construction requirements for dense grouting foundation reinforcement mainly include the following aspects:
1. Preparation before construction: Geological survey and testing work need to be carried out before construction to ensure the stability of the foundation and the necessity of reinforcement. At the same time, it is necessary to formulate a detailed construction plan and process flow, and inspect and prepare construction materials and equipment.
2.Selection and preparation of grouting materials: cement slurry, sodium silicate slurry and other materials are generally used for the reinforcement of dense grouting foundations, and suitable grouting materials need to be selected according to the specific conditions of the foundation and prepared according to the requirements.
3.Process requirements of grouting construction: When carrying out the reinforcement construction of dense grouting foundation, it is necessary to pay attention to controlling the flow rate, grouting amount and grouting pressure of grouting to ensure the uniform dispersion of grouting materials and fully fill the pores of the foundation. At the same time, it is necessary to carry out a reasonable grouting hole density and hole spacing arrangement to improve the strength and stability of the foundation.
4.Construction quality acceptance criteria: After the construction of dense grouting foundation reinforcement is completed, quality acceptance is required, including detection and evaluation of grouting depth, grouting amount, grouting pressure, and deformation of the foundation after grouting to ensure that the reinforcement effect meets the requirements.
Dense grouting foundation reinforcement has the following characteristics and reinforcement effects in the field of foundation reinforcement:
1. Flexibility: Dense grouting foundation reinforcement is suitable for various types of foundations, whether it is a hard rock foundation or a soft soil foundation, it can be reinforced by dense grouting method.
2.Improve the strength of the foundation: The reinforcement of the dense grouting foundation can fully fill the pores of the foundation, improve the compactness and strength of the foundation, so that the foundation can withstand greater loads and improve the stability of the foundation.
3.Control of foundation settlement: Dense grouting foundation reinforcement can reduce the settlement and deformation of the foundation, effectively control the settlement of the building, and protect the safety and stability of the building.
4.Improve the liquefaction resistance of the foundation: The reinforcement of the dense grouting foundation can improve the liquefaction resistance of the foundation by filling the pores of the foundation, and reduce the impact of natural disasters such as ** or floods on the foundation.
The requirements of dense grouting foundation reinforcement construction are of great significance and widely used in the field of foundation reinforcement. Through reasonable construction plans and process requirements, the strength and stability of the foundation can be effectively improved, and the safety and stability of the building can be ensured.
