Problems solved by technology

This method can provide a short-term anti-rust protection function, but due to the long time interval from the completion of the iron tower foundation to the installation of the iron tower, there is a hidden danger of external force damaging the anchor bolts
After the anchor bolts are damaged, it will cause inconvenience to the subsequent installation of the iron tower, and sometimes even the pile foundation has to be refilled. In this case, it will not only affect the progress of the electric power construction, but also cause unnecessary economic losses

Embodiment Construction

[0034] like Figure 1 to Figure 15 As shown, the present invention mainly includes cylinder body 1, mounting ring 2, end cap 3, first drying assembly, second drying assembly, spraying assembly and final protection assembly. The present invention will be described in detail below with reference to the accompanying drawings.

[0035] like figure 1 As shown, the cylinder body 1 is the main body of the present invention, and the cylinder body is a circular hollow plastic part, which can be made of PVC material. The lower end of the cylinder is open and the upper end of the cylinder is sealed. A mounting ring 2 is threaded on the inner wall of the lower end of the cylinder. The mounting ring is a circular plastic part. Threads are provided on the outer wall and the inner wall of the mounting ring. The threads on the outer wall of the mounting ring are used to cooperate with the inner wall of the cylinder. The threads on the inside wall of the mounting ring are used for mounting o...

Abstract

The invention provides a protecting device for an extra-high pressure engineering foundation bolt and relates to the technical field of foundation bolt protection. The protecting device is used for realizing the rustproof protection and external force damage protection for the foundation bolt and preventing the influence on the schedule of power construction caused by the damage to the foundation bolt. The protecting device can realize the dehumidification in a barrel through first and second drying assemblies, so as to prevent the rusting of the foundation bolt caused by the higher humidity in the barrel. A spraying assembly is used for spraying anti-rust oil on the foundation bolt, so as to further prevent the foundation bolt from being rusted. Lastly, a protecting assembly is arranged, the blasting of a balloon is performed when the barrel is damaged by an external force, so that the anti-rust oil is sprayed on the foundation bolt. When the foundation bolt is exposed, the rusting speed of the foundation bolt is reduced. The barrel has a certain protecting function to the foundation bolt and can prevent the foundation bolt from being damaged by the external force. The device can prevent the foundation bolt from being rusted, can prevent the damage caused by the external force to a certain degree, can ensure the schedule of power construction and can avoid unnecessary economic loss.

Description

technical field [0001] The invention relates to the technical field of protection of anchor bolts, in particular to a protection device for antirust protection and external force damage applied to anchor bolts in the field. Background technique [0002] In the existing electric power UHV construction process, when the cast-in-situ pile foundation is constructed, the anchor bolts are directly exposed to the air. Anchor bolts will rust when exposed to the air for a long time. At present, butter is applied and a plastic film is wrapped around them for anti-rust protection. This method can provide short-term anti-rust protection, but due to the long time interval from the completion of the tower foundation to the installation of the tower, there is a hidden danger of damage to the anchor bolts by external force. When the ground anchor bolts are damaged, it will cause inconvenience to the subsequent installation of the iron tower, and sometimes even the pile foundation has to be...
