1: The role of pile foundation grouting pipe.
Pile foundation grouting pipe is a new type of concrete structure specially used for cement mortar to fill pores and reduce foundation settlement. It has good performance, which can effectively prevent foundation subsidence and deformation, reduce foundation load, and improve engineering stability. The pile foundation grouting pipe is composed of two parts: the pipe and the support: the steel pipe support is the foundation, and the material selection requires high tensile strength and compressive strength, and the compressive strength must be greater than 100MPaThe other parts are made of ordinary steel bars or prestressed steel wires as the skeleton materials, and the design requirements are relatively low. Due to the particularity of this structural system, the construction process is more complicated. Things to look out for include:1When carrying out hoisting, it should be ensured that the drilling machine is firmly mounted on the support frame;2.Before pouring concrete, the surface debris should be removed and the surface should be cleaned up
2: Material selection of pile foundation grouting pipe.
The material selection of the pile foundation grouting pipe is very important. Different types of pile foundation grouting pipes have different characteristics, so there are many factors that need to be considered when choosing pile foundation grouting pipes. First of all, it is necessary to determine the use conditions and requirements of the pile foundation grouting pipe to ensure that the material meets the requirements of the useSecondly, the pile foundation grouting water pipeline system is designed according to the requirementsAgain, it is necessary to consider the interaction between the pile foundation grouting pipe and other components, such as concrete frame columns, reinforced concrete walls or steel beams, etc., whether they can withstand the corresponding loads. In addition, the influence of the pile foundation grouting pipe on the surrounding environment should be considered, including factors such as climate, topography, soil properties and groundwater level.
3: Design requirements for pile foundation grouting water pipeline.
A pile foundation grouting pipe is a pipe that injects water from a borehole into the interior of a concrete structure. It not only has the function of transporting water and preventing groundwater leakage, but also plays a role in reducing soil erosion. Therefore, many factors need to be considered in the design and construction of pile foundation grouting pipes: - sediment sedimentation, groundwater level rise and fall and drainage speed, etc.;- The shape and size of the building itself;- Stratigraphic characteristics and changes in groundwater levels, etc. According to the above requirements, the pile foundation grouting water pipe is reasonably laid out and the pipeline material is selected.
The addition of steel fibers makes the pile foundation grouting pipe more strong and durable. At the same time, these steels also have good tensile properties, which effectively prevent concrete cracking. Therefore, these steels are one of the very useful materials for building construction.
