Connecting construction method for vertical prestressed tendon and anchoring steel bar of prefabricated solid pile

Abstract

The invention relates to a connecting construction method for a vertical prestressed tendon and an anchoring steel bar of a prefabricated solid pile, and belongs to the technical field of prefabricated pile construction. The connecting construction method comprises the steps that a connecting sleeve is prepared firstly, then an inverted-truncated-cone-shaped jacket is installed on a prestressed tendon and clamped and fixed in an inverted-truncated-cone-shaped bayonet in the bottom of the connecting sleeve, a compression spring is installed in the connecting sleeve, then a pier head with a connecting thread is arranged at the end of the anchoring steel bar, and finally, the pier head is in threaded connection with the interior of a top sleeve opening of the connecting sleeve. The connecting construction method is high in practicability and easy to operate, the connecting quality of the pile head anchoring steel bars can be effectively guaranteed, the workload of field operators is relieved, cost is saved, and consumption of a large amount of manpower and material resources is avoided.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to the technical field of prefabricated pile construction, in particular to a construction method for connecting vertical prestressed tendons and anchoring steel bars of prefabricated solid piles. Background technique [0002] During the construction of prefabricated piles in construction projects, there are common quality defects such as pile head damage, deformation, and embedded parts damage, which lead to the failure of reliable and effective connection of pile head anchoring reinforcement. In this regard, the traditional method is to use the on-site pier of prestressed tendons. On the one hand, the entry and operation of the pier machine has high requirements on the on-site construction work surface, and it is not suitable for soft soil foundations, and even cannot be operated; on the other hand, the traditional This method will increase the workload of on-site op...

[0002] In the construction process of prefabricated piles in construction projects, there are common quality defects such as pile head damage, deformation, and embedded parts damage, which lead to the failure of reliable and effective connection of pile head anchoring reinforcement

In this regard, the traditional method is to use the on-site pier of prestressed tendons. On the one hand, the entry and operation of the pier machine has high requirements on the on-site construction work surface, and it is not suitable for soft soil foundations, and even cannot be operated; on the other hand, the traditional This method will increase the workload of on-site operators, increase construction costs, consume a lot of manpower and material resources, and eventually lead to a decline in construction quality and delays in the construction period.
