Jines Construction selects the safest, effective and economical grouting technology and grout materials, and implements site improvement tasks in accordance with standard operating procedures

The construction targets cover all types of soil strata, fractured rock plates and complex formations. Scope of work includes: building foundations, highway tunnels, rapid transit projects, underground pipelines, reservoir dam foundations, bridge piers, pile side reinforcement, horizontal channel excavation, etc. It is necessary to reduce the permeability coefficient, improve the bearing capacity, increase the shear strength, fill the voids in the formation, and compact the formation.

During the execution process, various key parameters are monitored and recorded simultaneously, and the operation mode is analyzed and revised in real time to achieve the best site improvement effect.

In accordance with the degree of groundwater inrush and stratum conditions, Jines Construction selects the most rapid and effective plugging methods to prevent the escalation of engineering disaster.

Possible water inrush situations include: excavation of foundation pits, TBM launch and arrival sites, rock tunneling, underground pipeline joints, tunnel drilling and blasting, vertical shaft digging and other projects that are located below groundwater level or in confined water strata.

Advanced technology and grouting materials imported from abroad and technology independently developed by the company are adopted during execution. With rich planning experience, the best solution is quickly proposed, and the safest and fastest operation mode to greatly reduce project losses and construction delays is used.

Jines Construction adopts single or compound repair methods for leakage cure and prevention, building repair and structure reinforcement, according to the structural damage. Appropriate technology and materials are selected to achieve permanent leakage prevention and meet the requirements of safety regulations.

The processing objects include buildings, tunnels, dams, bridges and various underground projects that are being constructed or in use. In addition to the use of various plugging, bonding and surface treatment materials to achieve anti-seepage and reinforcement effects, advanced treatment technologies are also used to prevent potential hazards that may cause long-term structural deterioration or corrosion to ensure long-term safety and comfort.

Soil pollution is a common phenomenon in China, a developing country, and one of the main reasons for the medical burden on local governments.

Jines Construction extends the ground improvement grouting technology, in cooperation with professional design units and pharmaceutical suppliers.

Depending on the nature of the pollution, physical, chemical, biological and other treatment methods are used, with professional physical detection technology, to effectively remove long-term accumulated soil pollution.

Scope of application includes various types of shallow to deep pollution from petroleum, organic, chlorocarbon cyanide, low-level nuclear energy and other types of high and low permeability strata. With a diverse professional team using technology integration and in combination with innovative automatic grouting systems, Jines Construction has the professional ability to use grouting technology to effectively eliminate soil pollution.
