Anchoring cement Supplier

GENERAL

The product is an inorganic mixed material, which has the characteristics of fast hardening, high strength, micro expansion, cold operation construction and no pollution to the environment. Eliminates the need to boil and heat the sulphur anchoring spikes to avoid the possibility of cracks in the concrete sleepers and bridge sleepers due to local heating and reduce the service life of the spikes. It is allowed to construct under the temperature environment above -10℃, and the result is good after 2 million fatigue tests.

Application

1. Anchoring of railway concrete sleepers with spikes, prefabricated bridge cementing joints, and anchoring of anchor bolts for mechanical equipment.

2. The rapid construction of anchor rods for supporting surrounding rock in underground projects such as railways, tunnels, water channels, coal mines, bridge pier reinforcement, earthquake resistance of houses, metallurgical mines, etc., as well as the anchoring of pull nails in concrete structure reinforcement projects, and can meet the requirements of steel welding Require.

Construction process

1. Take out the old road studs, clean up the dust and debris in the holes of the road studs and moisten the holes.

2. Use a squeegee (round head) to hold the bottom of the anchoring frame, and place the anchoring frame into the predetermined position at 45° from the reserved hole: Block the opening of the anchoring frame positioning plate toward the sleeper to facilitate the placement of the baffle seat .

3. Take the road stud anchoring agent in an amount of 04 kilograms for each road stud hole, and the water consumption is 13-15% of the weight of the road stud anchoring agent. When mixing the slurry, first pour two-thirds of the water, and then mix the remaining water while stirring to achieve a certain consistency and good fluidity. Pour the mixed spike anchoring agent into the hole from the middle of the anchor frame, about 2 cm from the top of the hole.

4. Rotate and insert the insulated spiral spikes as soon as possible after grouting to make the round table fall on the anchoring frame positioning plate and straighten it. Scrape the overflowing slurry with a squeegee bar and flatten it to make the appearance beautiful.

5. After anchoring for 30 minutes, you can install the fastener and tighten the nut by hand. After 60 minutes, you can use a wrench to tighten slightly
