Luoyang Xinben Machinery Co., Ltd. produces a series of water-expansion (expansion) bolts based on actual use at home and abroad. The water-expansion (expansion) anchor rod is made of a steel pipe with a concave section of the wall. The anchor rod is expanded by high-pressure water flow, so as to completely adhere to the irregular hole wall of the drilled hole. The water expansion (expansion) anchor rod can produce a full length along the anchor rod. Long friction, mechanical locking and pressure strengthen the rock mass.

　　The characteristics of the water-expansion (expansion) anchor rod produced by Luoyang Xinben Machinery :

　　1. The construction speed is fast, no grouting is needed, thus saving the application of cement slurry, which is convenient and quick.

　　2. It has excellent vibration resistance and can be installed close to the working surface.

　　3. It can generate force with shear displacement.

　　4. The full-length rod swells close to the irregular hole wall, and any section can become an independent part to play a supporting role.

　　5. Surface anti-corrosion treatment, no need to worry about corrosion.

　　Luoyang Xinben Machinery Co., Ltd. is a modern and established enterprise with strong capital and strong production capacity. It has 12 developers and 16 professional technicians. At present, the main products are: water-expandable bolt, ordinary hollow grouting bolt, reverse circulation hollow grouting bolt, prestressed bolt, self-advancing hollow grouting bolt, expanding shell hollow grouting bolt, Combined hollow grouting anchor rod, and a series of products. The company's products are produced, sold and serviced in strict accordance with the relevant national standards and the relevant standards of the Ministry of Coal and Railways.

　　The company’s products have been applied and promoted in many domestic projects, such as railway engineering, water conservancy and hydropower engineering, highway engineering, urban infrastructure construction, subway construction, coal mine tunnels, slope support, coastal dams, etc. Of praise. Products are exported to South America, Africa, Australia, Europe and other countries and regions, laying a good foundation for large-scale international cooperation.

　　The company has always been adhering to the enterprise tenet of "cooperating happily, with excellence in nature", happily cooperating with all customers, forming close friends who help each other, relying on strong scientific research strength, continuous expansion, and continuous improvement of product performance. Quality continues to meet the new needs of friends.

　　Construction method:

　　Put the water-expandable anchor with a backing plate, put it into the drilled rock hole, connect the water injection nozzle of the high-pressure pump for water injection, when the set pressure is reached, the high-pressure pump automatically stops water supply, remove the water injection nozzle, and proceed Construction of an anchor hole.
