Grout pump for doing micro pile
Grout pump for doing micro pile has the characteristics of small volume, light weight, energy saving and electricity saving, large discharge volume without pulse, high working pressure, and convenient movement. The grout pump doing micro pile is an ideal mortar conveying equipment suitable for small and medium-sized projects. Gaode Co., Ltd. is a specialized manufacturer of grouting pumps integrating scientific research, production and sales. Since its establishment more than ten years ago, the company has always been committed to innovation in technology and management, and has developed grouting equipment products suitable for railway, hydropower, transportation, coal metallurgy, geology, mine defense and chemical industries.
The performance and quality of the grout pump for doing micro pile play a decisive role in the safety, quality and efficiency of the grouting project.
The cement grout pump for doing micro pile main advantage is that the grouting hole is short, a portable drilling rig can be used, the hole inclination is easy to control, the grouting effect is good, and it is easy to detect; the disadvantage is that the grouting construction takes up the construction period of the well and the downhole operating conditions are poor. This method is applicable to situations where the aquifer is buried deep and the distance between the aquifers is large. The ement grout pump for doing micro pile can not only inject mortar, mortar, cement slurry, but also spraying operations with an air compressor and spray gun. The grout pump for doing micro pile is mainly used for grouting reinforcement in mine shafts, railway roads, tunnels, hydro power projects, etc.
The grout pump doing micro pile is a new type of micro-pile construction method, the main process is as follows:
1. Form a hole with a diameter of 0.25m～0.4m on the foundation through a drilling machine;
2. Inject clean water into the drill hole through the hollow drill pipe of the drill rig to clean the hole once;
3. Put out the drill pipe, and put the steel cage and pouring pipe into the drill hole;
4. Inject clean water into the borehole through the perfusion catheter to clean the hole twice;
5. Pour the pre-prepared fine stone concrete into the borehole through the pouring pipe until the fine stone concrete is poured out of the borehole to form a micro-pile with a diameter of 0.25m to 0.4m.
The strength of the pile body after the pile is formed by the stone grouting method in the prior art is relatively small, which has a great influence on the bearing capacity of the micro-pile. For the grout pump for doing micro pile, the strength of the pile body is controlled by preparing fine-stone concrete of different strength grades, which effectively guarantees the pile body strength of the prepared micro-pile.
