Embodiment approach

[0023] In the first embodiment of the present invention, please continue to refer to figure 1 , figure 2 with image 3 shown. The left and right sides of each steel plate column 2 are bent to form a vertical bent portion 21 , and the two bent portions 21 of each steel plate 2 face the direction of the wooden pile 1 respectively.

[0024] In the second embodiment of the present invention, the distance between the two bent parts 21 on the left and right sides of each steel plate column 2 is greater than the distance between the left and right sides of the wooden pile 1, so that the two steel plate columns 2 can enclose the wooden pile. Pile 1.

[0025] In the third embodiment of the present invention, the length of the steel plate column 2 is more than 9 meters.

[0026] In the fourth embodiment of the present invention, the above-mentioned connecting member 31 is a chain, and the chain is fixedly connected with the collar 3 .

[0027] On the basis of the above, the presen...

Abstract

The invention discloses a pile extractor with a vibrating lantern ring and an application method thereof. The pile extractor with a vibrating lantern ring comprises a wood pile buried in the land to be extracted. Two steel plate columns are respectively arranged on the two sides of the wood pile. A loop used for extracting the wood pile is circuitously sleeved on the top of the wood pile. The loop is also provided with a connecting member. The application method include the steps of: a) piling the two steel plate columns into the land around the wood pile through an external pile extractor; b) sleeving the top of the wood pile with the loop; and c) extracting the wood pile with the external pile extractor through the loop. By pilling of steel plate columns and pulling out the wood pile sleeved with the loop, the whole pile extracting process is rapid and convenient, pile extracting efficiency is high, only small site is required, and pile extracting cost is low.

Description

technical field [0001] The invention relates to a protective device in the field of construction, in particular to a device for quickly extracting piles by using a vibrating collar and an application method thereof. Background technique [0002] In order to ensure the original style of the old buildings and at the same time make the old buildings meet the requirements of use, more and more interior space reconstruction and reinforcement constructions appear in the old buildings. However, during the construction of many old buildings in that period, a large number of wooden piles were driven into the ground, which virtually made it more difficult for the foundation reinforcement of the old buildings in the later period. Therefore, the wooden piles under the old buildings must first be removed before foundation construction to clear. [0003] At present, there are generally two kinds of common pile extraction techniques: one is the occlusal full-sleeve pile extraction, which ...
