1. Preparation 1. Check whether the installation of the bolt meets the design requirements and find the problem in time.
2. Clean up the debris from the blast site and install the sprayer at a stable and safe location on the surrounding rock of the top wall. The gap between the rails should not be less than 0.5m. Connect the wind and water pipelines. The feeding pipeline shall be straight and shall not have sharp bends. The joints shall be tight and no leakage of air shall be allowed. It is forbidden to use non-static antistatic plastic tubes as conveying tubes.
3, check whether the spraying machine is in good condition, and send no-load test run, fasten the friction plate, no leakage phenomenon.
4. Before blasting, the rock face must be washed with high-pressure feng shui. Thickness marks shall be installed on the vault and the two gangs of the roadway.
5, spray personnel to wear complete and effective labor protection products.
2, with spices 1, the use of sieves, buckets to check whether the coarse aggregate ratio meets the requirements.
2, check whether the aggregate moisture content is qualified.
3, according to the design ratio of cement and aggregate into the mixer, the material should be uniform. Cement: Sand: gravel, concrete with a weight ratio cement: sand: stone = 1:2:2, artificial mixes use tidal mix, cement, sand and stones should be cleaned and mixed three times to make it evenly mixed.
4, check the mix of moisture content of the tidal material, required to be able to hold into a group, release the hands like scattered non-dispersed, blowing smoke-free.
5, quick-setting agent according to the cement content of 2.5-4% evenly added in the nozzle of the spraying machine.
3. Before the spraying work begins, the old belt should be laid on the spraying site so as to collect the rebound material. The rebound rate should not exceed 10%.
1, open water, open air, adjust the amount of water, to maintain the wind pressure must not be less than 0.4MPa, the water pressure should be higher than the wind pressure 0.1MPa, plus the amount of water with the hands of the sprayer to control the water-cement ratio 0.4.
2. The sprayer operates the sprayer to flush the rock face from top to bottom.
3, power transmission, open spray machine mixer, spray gunning.
4. Adjust the amount of feng shui again according to the feeding conditions to ensure that there is no dry spot on the spray surface, no runny, strong adhesion and less rebound material.
5. The sprayer sprays in sections in the order from the bottom to the top and back of the wall.
6. When sprayed, the sprayer should be sprayed vertically as far as possible. The included angle should not be less than 70 degrees.
7. When spraying, the trajectory of the nozzle should be in a spiral shape. According to the diameter of 200-300mm, a round semi-circular method can move evenly and slowly.
8, a shot of concrete thickness of 50 ~ 70mm, and timely re-spray, re-spray interval time shall not exceed 2 hours. Otherwise, use high pressure water to re-flush the sprayed surface.
9, should be equipped with two people, one person holding the nozzle jet, one auxiliary lighting and responsible for contact, observe the top of the security and jet quality.
4. Shutdown 1. After the shotcrete is completed, press the order of the first stop, the stoppage of the water, and the final shutdown of the power after the power failure.
2. After the spraying work is completed, remove the sprinkler, clean the mortar and material inside and outside the water ring and sprayer, and wind up the wind pipe.
3. Clean up and collect rebound materials, and use clean materials in shifts.
4. Spraying concrete began to spray for 2 hours after curing, and core strength was measured after 28 days.
