Yulong pipe lubricant is used to lubricate the secondary lined concrete delivery pipes of tunnels

1. Technical introduction

This product is formulated with a variety of polymeric materials. It will dissolve quickly after mechanical stirring for 2-5 minutes at room temperature, forming a viscous, smooth and transparent liquid. This achieves the purpose of pumping concrete without using mortar. When using this product, first put 20-30 kg of water in the hopper, start stirring, slowly pour the product into the water, stir for 1-2 minutes and then stop stirring. Wait for this product to react in water for 5 minutes and then stir for 1 minute to form a viscous, moist liquid. When working, first pump the pump tube agent into the pump tube, and then put the concrete into it to start working.

2. Features and advantages

1) Low cost and obvious economic benefits. The unit price of each pack of this moisturizing agent is about 5 yuan. The dosage of the moisturizing agent depends on the length of the pipe: 1 bag for a pipe length of less than 50 meters, and 2 bags for a pipe length of 50-100 meters. Generally, 1-2 packs are used at a time, and the cost is 5-10 yuan/time. .

　2) Save materials. In the context of the shortage of machine-made sand production and the reduction of river sand mining, it effectively reduces resource consumption, saves materials, and ensures the supply of other concrete.

3) Improve construction efficiency and save construction period. In traditional secondary lining construction, the concrete hoses must be moistened with mortar after the first truck of concrete arrives at the construction site. However, with the use of moistening agents, the concrete hoses can be processed in advance before the concrete tanker arrives, effectively saving a single time. Second lining construction time.

4) The quality of the secondary lining concrete is guaranteed. For the secondary lining construction where the concrete is transported far away, the long-distance transportation of concrete and mortar as a whole often results in a large slump loss of the secondary lining concrete, which in turn affects the quality of the secondary lining concrete.

3. Application effect

After this product was put into use, it greatly improved the construction progress of the secondary lining concrete, which not only reduced the use of raw materials, but also reduced the utilization rate of tank trucks. It is convenient and quick to use, greatly saves economic costs, and has obvious economic effects. </p
