Introduces the important role of conical pile tip
Tapered pile tip supplier: generally refers to prestressed tapered pile tip, which is used for prestressed concrete foundation construction, front end, installation, guidance and
The tapered pile tip is usually the end of the prestressed cylinder pile, which is used to construct the prestressed concrete pile foundation and the front end of the cylinder pile. During the construction of cylindrical pile, the head of cylindrical pile shall be installed for guiding and sealing. Generally, during the construction of prefabricated pile with tapered pile tip, the pile tip is welded with the pile head, and the pile body enters the soil layer to avoid damage to the pile head and pile body inclination. Verticality control pile can better enter the bearing layer. The shape of conical pile tip varies with different geological environment conditions and management methods in China, and is derived from various shapes and specifications.
The main function of conical pile tip is to reduce the probability of pile fracture. By providing a pile tip, the pile tip can be firmly inserted into the soil layer. Cylindrical pile can be considered as a relatively homogeneous material. In the process of pile driving, under the combined action of the impact energy of the pile hammer, the dead weight of the pile body and the soil reaction force, the pile end is subjected to very complex stress, and the dimensions of each part are different. If the pile tip is added to the pile tip and the pile end is constrained, the steel plate has sufficient thickness, such as the beam and plate force in the reinforced concrete structure, so as to avoid the cylinder pile directly bearing the resultant force, and then the medium with sufficient strength is added between the pile head and the soil layer. After passing through the pile end and being stressed, the force is relatively evenly transferred to the cylindrical pile to avoid the damage of the cylindrical pile due to local over-stress.
Cylindrical pile is a homogeneous material. When it is inserted into the soil, it has a certain effect on the pile hammer. If the cone point is added at this time, it is equivalent to the binding force on the pile. This force is equivalent to a relatively thick steel plate, which can reduce the local pressure caused by the damage of the cylindrical pile. If the steel plate is subjected to a huge impact, the object will deform. If there is still room for deformation, the energy transmitted by the pile during deformation will be absorbed and the cylindrical pile will not be damaged. If there is no expansion space when the pile tip is deformed, the pile may break. When making the pile tip, if there is no bottom seal, some soil layers may develop into the cylinder pile. With the accumulation of more and more soil layers in society to a certain degree of education, the soil environment inside the pipeline enterprise will have a certain impact on the cylindrical pile. Once the pile cannot bear the working pressure, it will be damaged. If there is no bottom seal, the soil layer will enter the inner cavity of the cylindrical pile. With the increase of footage, more and more soil will enter the pile and may choose to withdraw to some extent.
