Vibrating auxiliary device for small-diameter root pile and using method of vibrating auxiliary device

Abstract

The invention belongs to the technical field of river regulation, and particularly relates to a vibrating auxiliary device for a small-diameter root pile and a using method of the vibrating auxiliary device. The device comprises a pile casing placed in a preformed hole of the root pile, and the pile casing is in a hollow shape; a cover plate capable of being overturned downwards is arranged at the bottom of the pile casing, and a steel plate clamped by the vibratory pile driver is arranged at the top of the pile casing. The pile casing in the vibration auxiliary device has an extrusion effect on soil on the hole wall, the phenomena of hole collapse, hole shrinkage and the like are avoided, and it is guaranteed that the root pile is smoothly placed into the preformed hole; and the arranged cover plate which moves downwards and unidirectionally is beneficial to preventing soil from entering the vibrating auxiliary device when the vibrating auxiliary device is lowered, meanwhile, sediments at the bottom of a drill hole can be compacted, and hole cleaning measures in the grouting pile forming process are eliminated.

Description

technical field [0001] The invention belongs to the technical field of river course management, and in particular relates to a vibration auxiliary device for small-diameter tree root piles and a use method thereof. Background technique [0002] The tree root pile is a small bored cast-in-place pile. The existing construction method of the tree root pile is generally to use the grouting pile method, as follows: first use the auger drill to form the hole, then clear the hole, use mud to protect the wall, and then put it into the pile. The reinforcement cage is put into the grouting pipe at the same time for grouting, and after the grouting is completed, it is manually vibrated to form a pile. [0003] However, for the small-diameter tree root piles with a diameter of 200-300mm, due to the small diameter of the piles, when using the grouting method to form piles, the grouting process is very difficult and cumbersome to construct, and because the hole diameter of the tree root p...

Problems solved by technology

[0003] However, for small diameter tree root piles with a diameter of 200-300mm, due to the small diameter of the pile, when the pile is formed by the grouting method, the grouting process is very difficult to construct , the construction process is cumbersome, and because the hole diameter of the tree root pile is too small, it is extremely inconvenient to clean the hole, and at the same time, it is easy to have collapsed holes and shrinkage holes after drilling, and it is easy to cause problems such as insufficient vibration when forming piles
