Equipment
Cement mixing pile is an effective form of soft foundation treatment using cement as the main solidification agent. It uses a mixing pile machine to spray cement into the soil, fully stir, and cause a series of physical and chemical reactions between the cement and the soil, making the soft soil hard and improving the strength of the foundation. The treated soft soil foundation has a significant reinforcement effect and can be quickly put into use. Suitable for handling muddy soil, muddy soil, peaty soil, and muddy soil.
Cement mixing piles can be divided into wet and dry methods according to the material spraying state. Wet method mainly involves cement slurry, which is evenly mixed and easy to re mix, and the hardening time of cement soil is long; The dry method mainly uses cement powder, and the hardening time of cement soil is short, which can improve the strength between piles. Cement mixing piles are divided into single axis mixing piles, double axis mixing piles, and three axis mixing piles according to the main construction methods.
Main characteristics of machinery
1. The drilling rig part of this machine is mechanically driven: it has multiple speeds for rotation and feeding (or lifting), and is equipped with an overload protection device, which is fully functional and easy to operate and reliable.
2. The chassis of this machine is hydraulic walking type, which can move vertically and horizontally, and is quick and easy to operate for hole positioning; Strong maneuverability.
3. The drilling rig adopts a chain type pressure mechanism, and within the reinforcement depth range, the drilling tool can continuously drill or lift. The drilling tower (derrick) and drill pipe can be lengthened or shortened according to the reinforcement depth, resulting in high work efficiency.
4. The lifting and lowering of the mast is carried out by hydraulic operated oil cylinders, which is simple and reliable.
5. The drilling footage is equipped with a depth gauge and digital display for easy operation and control.
6. This machine is equipped with various special drill bits for powder spraying and grouting piles, which are unique in pile forming performance for construction under different soft soil conditions.
7. This machine is equipped with equipment such as large and small ash cans for powder spraying (dry spraying method) reinforcement treatment, further expanding the application range. The powder spraying system adopts electronic calculation, digital display, and mechanical stepless control, allowing for free adjustment of powder spraying amount.
8. The powder spraying system uses large and small ash tanks for feeding (cement or lime, etc.), which is convenient and efficient
9. This machine is powered by a three-phase asynchronous motor, with low power consumption and a wide range of applications.
10. The entire machine has a compact structure, flexible maneuverability, low grounding pressure, good stability, and can also be applied to construction sites with narrow venues and poor ground conditions.
11. The host adopts a modular assembly, which is convenient for assembly, disassembly, and transportation during transit; The main components are mostly standard parts, with a high degree of universality and convenient use and maintenance.
12. The spraying system adopts a stepless speed regulation method to control the spraying amount, and the knob adjusts the meter display, making it convenient and reliable.
