Grouting construction of new mining filling and sealing materials
) Malisan price Malisan manufacturer where to sell Malisan real price Malisan reinforcement Malisan color Malisan formula
< br/> Specific construction steps of Malisan grouting construction
Malisan construction steps include drilling and sealing holes. The required drilling diameter
, depth
and inclination angle are determined according to the site conditions
br/> Assemble the multi-function pump and its accessories
Start grouting. Insert the two suction pipes into the Malisan resin and catalyst barrels respectively. The piston moves under the action of the air motor. Due to the effect of pressure, The raw materials enter the delivery pipe through the piston and are transported to the injection gun. They are injected into the coal seam through the injection gun. The raw materials penetrate into the cracks and react quickly to achieve the purpose of reinforcement
Stop grouting and flush the pipeline and mixing gun with resin
Change the hole grouting and repeat the
steps
After the grouting is completed, clean the multi-function pump and accessories with cleaning agent. When cleaning, use water on the resin side and engine oil on the catalyst side. (2) Preparation work required
, preparation of power air source requirements
, preparation of air ducts, required diameter
inches
The length depends on the swing from the air source interface to the pump The distance depends on the placement point
. Prepare two
high-pressure pipes. The length depends on the distance from the pump placement location to the construction site
. Transport all raw materials and equipment to the construction site. On-site
, arrange professionals to drill holes
and equip
construction workers
, prepare cleaning agent, two barrels of water and two barrels of emulsion or engine oil
, preparation Enough cotton yarn and wooden wedges are used to prevent raw materials from flowing out along the cracks and causing waste. Safety technical measures
Construction personnel must strictly implement the inspection first and then work and ask questions
During work, they must strictly follow the construction measures to prevent illegal operations.
When personnel enter the coal gang for construction, they must lock the slide in front of the work and turn on the switch to stop, and implement the inspection first and then work and knock on the gang to ask questions.
When working, arrange for special personnel to monitor and inspect the working site and surrounding roofs. If any unsafe hazards are discovered, they must be dealt with in a timely manner to ensure safe construction.
When drilling holes, other personnel are strictly prohibited from standing on both sides of the drill rod to prevent injuries from breaking the drill rod.
