1, the construction is quick, this construction uses the drilling machine as the split type, the removable is good, moves, installs conveniently. The utility model can remotely operate, and can be perforated at one time. The utility model has more than 6 times the efficiency of the ordinary drilling rig.2, small footprint, no common drilling pile, mud tank, steel processing space and so on.3, construction safety, without digging pile, explosive, artificial underground operation and other unsafe factors.4, the construction process and conditions are simple, the quality is easy to control.5, the process of nearby rivers, villages, no pollution, no noise.6 、 small pile diameter and low cost.
The rail as a "pile", through the piling machine, pile hammer or other means to sink into the soil, from the lateral support of the soil or vertical bearing role, that is, rail pile. The strength of the rail is two or three times that of the ordinary Q235 steel, and the price is high, but the bending modulus is much smaller than that of the I-beam, so it is not worthwhile to consider it from the cost point of view. Steel rails are usually used only when existing old rails are used as temporary structures or for emergency purposes.
The rail is used as the material of the pile foundation to directly push the rail vertically into the ground to the design depth. The superstructure is supported by the friction force between the rail and the surrounding soil and the bearing capacity of the rail top and the bearing soil. Generally used for better soil conditions, buildings are not very large
Rail pile: through the large air compressor air supply to the impactor, the use of YG-80 engineering drilling machine drive special drilling hammer, impact hole. Then enter the rail, and then pour the cement mortar from bottom to top. After solidification, the rail becomes a pile body, and the pile is mainly supported by the rail to bear the bending moment.Scope: suitable for highway, municipal, railway, housing construction and other soft foundation and all kinds of landslide reinforcement.
