The bridge pile foundation is composed of multiple piles driven or sunk into the soil and the bearing platform connecting the pile top. In modern bridge construction, pile foundation is mostly made of reinforced concrete. In recent decades, reinforced concrete bored pile has developed rapidly all over the world. Choosing an efficient drilling equipment can make the pile foundation construction easier. Yichen auger is a very excellent drilling equipment. The auger is equipped with different types of drill pipes, and the maximum drilling diameter can reach 1-2m; At the same time, it is also equipped with extension rods of different lengths, and the maximum drilling depth can reach 12m. Auger has participated in many bridge construction projects to meet the needs of diversified bridge pile foundation construction.
Yichen drum cutter has many functions and is suitable for a variety of municipal projects
As a new type of modern construction equipment, drum cutter has a variety of functions and can perfectly replace traditional equipment such as crushing hammer and hydraulic shear. Therefore, it can be seen in many municipal projects such as honest road construction, tunnel construction and underground pipeline construction. drum cutter are divided into longitudinal drum cutters (excavation head) and transverse drum cutters. The application of the two types of drum cutter in utility work is also different.
The transverse drum cutter is suitable for milling pavement and wall. In urban road construction, the drum cutter can directly dismantle the cement pavement to be built. The demolished cement fragments are in the form of small particles, which can be directly used to backfill the subgrade, realize the reuse of resources and reduce the project cost. The efficiency of using milling excavator to dismantle cement pavement is much higher than that of traditional equipment such as crushing hammer. It is a very excellent construction equipment. The horizontal drum cutter also plays a great role in pipeline construction. Usually, small drum cutters are used to directly mill and excavate pipes with regular shapes to facilitate subsequent construction and simplify construction difficulty.
Longitudinal drum cutter (digging heads) are mostly used in tunnel engineering. First, the longitudinal drum cutter can directly excavate and dig out underground pipelines; Secondly, the longitudinal drum cutter can be installed on the shield machine and pipe jacking machine to realize the excavation of large tunnels. There are many types of longitudinal drum cutters with different diameters, and the diameters of milled tunnels are also very different. Customers can choose according to their needs.
