Before drilling:
1. Before the excavation of the foundation pit, the drilling machine must be based on the location and orientation of the hole, the viewing angle of the hole and the deep harsh structure. Twist drills cannot be replaced without approval. If you do not observe discipline, it is very easy to produce can not predict the analysis of security incidents. When installing the drill pipe, check the twist drill and check whether the drill pipe is blocked, not bent, no gap, and the transmission line is not damaged.
2. When digging with clean water, power supply is not allowed before digging. After intelligent backwater, it can drill water. In order to ensure sufficient total flow, Xi 'an drilling machine is overhauled, there is no dry well foundation pit excavation, long-term drilling, water must be released, the time of suction pump must be increased, and drilling can be terminated after specific drilling.
Drilling machine:
1. In the whole drilling process, the spacing must be accurately measured. Under normal conditions, every time the drill is 10 meters or the twist drill is disassembled and replaced, the drill pipe must be accurately measured once, and the deep depth of the drill hole must be checked and changed. Look at the reduction gearbox, shaft sleeve, vertical shaft transmission gear, etc., whether there is over-temperature, whether there is noise, if found the problem immediately terminate, find the reason, terminate to solve the difficulty, please do not. Very quick and high maintenance.
2. When digging with clean water, no power supply is required before digging. In addition to this, the water only comes back after drilling. And to ensure that you have sufficient total traffic. The rock dust in the hole must be long-term, and the water flow is increased to increase the use time of the pump and until the hole is drilled.
3. When the drilling equipment is disassembled and replaced each time, the drilling rig generally stipulates an accurate measurement every 10 meters to change the drilling depth. Even if overtemperature occurs in the transmission, coupling, vertical shaft transmission gear, etc., abnormal noise will not be transmitted. If it is not good, please terminate it immediately, investigate the reason and solve it within time. How to correctly operate the well excavator equipment in practice
Because of the prevalence of engineering projects in China, a variety of drilling service platforms are often used, and drilling rigs have already produced and processed wells. Key drilling, conducting underground drainage pipes, well washing practical operations, etc. are easy.
First, when entering the construction site, the drilling machine must be fixed on the drilling machine. The total area of the drilling rig is larger than that of the drilling rig seat, and there must be sufficient safe indoor space around.
Second, when installing the drill pipe, check the drilling machinery and equipment to ensure that the drill pipe is not blocked, not bent, and the stainless steel wire is not worn. Please do not prohibit drill pipe.
Third, the drilling machine must grasp the principle of drilling machinery and equipment and a full range of maintenance expertise, and there are a variety of common fault removal methods.
Fourth, the machine and equipment of the well drilling machine should be firmly loaded, and the turning or slope should be reduced in speed and fixed with stainless steel wire.
The above is the attention points summarized by the editor on drilling operations, hoping to be helpful to you in drilling projects.
