　　The small pipe taper machine plays a crucial role in the construction industry. A small conduit is an indispensable step in construction, as it can effectively penetrate into the wall. The pointed end at the front is relatively easy to penetrate, and the small holes on the steel pipe wall are added to enhance the strength of the surrounding rock. The small tube taper machine has a fast taper speed, and the taper of a pipe can be completed within one minute.

　　Layout of small conduits

　　(1) Common design parameters: steel pipe diameter of 30-50mm, steel pipe length of 3-5m, welded steel pipe or seamless steel pipe; The spacing between grouting holes for steel pipes is 100-150mm, and the spacing between steel pipes arranged along the arch in the circumferential direction is 300-500mm. The angle of steel pipes inserted outward along the arch in the circumferential direction is 5-15 °. The small pipes are load-bearing members, so there should be a certain overlap length between the two rows of small pipes in the longitudinal direction. The overlap length of steel pipes along the longitudinal direction is generally not less than 1m.

　　(2) Before installing the conduit, the working surface should be tightly and firmly sealed, cleaned, and the installation position should be measured before construction can begin.

　　2. Grouting material

　　(1) It should have good injectability, and the solidified body should have certain characteristics such as strength, impermeability, durability, and low shrinkage rate. The slurry should be. Grouting materials can be modified water glass slurry, ordinary cement single liquid slurry, cement water glass double liquid slurry, ultra-fine cement and other grouting materials. Generally, modified water glass is suitable for sandy soils, while cement slurry and cement mortar are suitable for pebble substrates.

　　(2) The main component of cement slurry or cement mortar is Portland cement with PO42.5 grade or above; The concentration of water glass should be 40-45 °, and the selection of additives should be based on different bottom layers and grouting processes.

　　(3) The selection of grouting materials and the determination of mix proportions should be based on engineering conditions and experimental results to determine the reference price for advanced grouting small pipe tip shrinking machine and precision constant small pipe tip machine.

　　Precautions for the small catheter tip machine: 1. Before operation, check whether there is any abnormal sound in the motor, whether the power cord is broken or damaged, and provide the small catheter tip machine for a long time. Check whether the oil is insufficient or leaking. If there is any abnormality, promptly notify the supervisor or machine maintenance for handling. Precautions for operating the small tube tip machine: 1. The equipment can compress 3-5 workpieces per minute, which is 3-5 times more efficient than ordinary lathe machining. 2: Each bed can produce 2000-3000 pieces per shift, which is very suitable for large-scale production. 3: The handling of small conduits must be handled with care and must not be struck randomly. 4: During transportation, to facilitate insertion and prevent the slurry from rushing forward. 5: Drill a 8mm overflow hole in the middle of the small conduit, arranged in a plum blossom shape (to prevent blind spots during grouting), with a spacing of 15cm and a range of 0.5m at the tail end; Do not drill holes inside the enclosure to prevent leakage of grout, and weld 6 ring stirrups at the end to prevent common defects such as cracking at the end of the small pipe tip machine in Anshun Town, Ningbuyi and Miao Autonomous County when setting up small pipes, which affects the connection of grouting pipes. The reference price for advanced grouting small pipe tip machine is the precise and constant small pipe tip machine.
