The following introduction to the method of pavement subsidence grouting measures is quite good, and by reading the following article, you will be able to have a deeper understanding of this.
Pavement subsidence grouting measure method, also known as pavement settlement repair grouting, is a construction method used to repair pavement subsidence problem. It fills the cavities or loose parts under the roadbed by injecting slurry to increase the bearing capacity of the foundation, restore the pavement to its normal height and flatness, and increase the stability and service life of the pavement.
Features: 1. High efficiency: Pavement sinking grouting is a rapid repair method, which can be repaired in a short time, thereby reducing the impact on traffic.
2.Economy: Compared to other pavement repair methods, the cost of sinking grout is relatively low. Because it can fill the existing cavities with filler material without the need for a full resurfacing of the pavement.
3.Long-term effect: The pavement repair after grouting has good stability and durability and can be maintained for a long time.
4.Environmental protection: The filling material used in pavement sinking grouting is usually environmentally friendly and has no pollution to the environment.
Construction process: 1. Pavement detection: It is necessary to test the pavement to determine the degree of settlement and the specific location of the problem.
2.Preparation: Clean the road surface of debris and dust. Preparation of grouting equipment and materials.
3.Pre-treatment: Depending on the situation, some pre-treatment work may be required, such as cutting and repairing cracks in the pavement.
4.Grouting construction: The use of grouting equipment to inject grout into cavities or loose parts under the pavement. Grouting is usually carried out by pre-punching holes, where slurry is injected into the holes to fill the holes.
5.Settlement observation: After grouting, a period of settlement observation is carried out to ensure that the repair effect is stable.
6.Pavement restoration: Surface trimming and restoration of the repaired area to smooth the pavement.
The pavement subsidence grouting measure method is a cost-effective pavement rehabilitation method. By injecting slurry to fill the voids and loose parts, the bearing capacity and stability of the roadbed are improved, so as to repair the problem of road subsidence. It is fast, economical, durable and environmentally friendly, and the construction process includes pavement inspection, preparation, pretreatment, grouting construction, settlement observation and pavement restoration.
