Description

A vibrating collar pile pulling device and its application method

technical field

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

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. to clear.

At present, there are generally two kinds of common pile extraction techniques: one is the occlusal full-sleeve pile extraction, which uses a machine to insert a steel casing around the pile to be extracted and slowly bury it into the bottom of the pile. After the bottom of the pile is pulled out, the steel plate at the bottom of the steel casing will be automatically closed, and then the pile will be pulled out as a whole by the machinery on the ground. The other is to use a full-rotary drilling rig to extract piles. This equipment can drive the steel casing to make a circle rotation to press the casing into the construction area to be pulled out, and then use the high-strength cutter head of the nozzle to remove obstacles such as soil, rock formations, and reinforced concrete. After the casing reaches the bottom of the pile, use hydraulic lifting equipment to pull out the pile. But there are following shortcoming in these two kinds of pile extraction methods: 1, in the overall pulling out process of full sleeve pipe, the frictional force between surrounding soil and sleeve pipe is too large, causes the pile extraction speed to be slow. 2. In the project where the site is small or the piles need to be pulled out indoors, the full-rotary drilling rig cannot be used to pull the piles because there is not enough space. 3. The cost of these two pile pulling construction methods is high, and it takes a long time, which has a great impact on the construction period.

Contents of the invention

The purpose of the present invention is to provide a vibrating collar pile pulling device and its use method to solve the problems of slow pile pulling speed in existing pile pulling methods, insufficient space to use full-rotary drilling rigs for pile pulling, high construction cost, and long time consumption. .

In order to achieve the above object, the technical scheme that the present invention takes is:

A vibrating ring pile pulling device, including a wooden pile buried in the ground to be pulled out, wherein a steel plate column is arranged on both sides of the wooden pile, and a steel plate column for pulling out is sleeved around the top of the wooden pile. The collar of the stake is provided, and the collar also has a connecting part.

In the above-mentioned vibrating collar pile pulling device, a vertical bending part is formed on the left and right sides of each steel plate column, and the two bending parts face the direction of the wooden pile.

In the aforementioned vibrating collar pile pulling device, the distance between the two bent parts of each steel plate column is greater than the distance between the left and right sides of the wooden pile.

In the aforementioned vibrating collar pile pulling device, the length of the steel plate column is 9 meters.

In the aforementioned vibrating collar pile pulling device, the connecting component is a chain, and the chain is fixedly connected to the collar.

A method for using a vibrating collar pile pulling device, which includes the vibrating collar pile pulling device described in any one of the above; step 1: drive the two steel plate columns into the wooden pile with an external pile pulling machine In the ground; step 2: set the collar on the top of the stake; step 3: pull out the stake with an external pile extractor through the collar.

The method for using the above-mentioned vibrating collar pile pulling device, wherein yellow sand is filled into the hole from which the wooden pile is pulled out.

The present invention has adopted above-mentioned technology, makes it have positive effect compared with prior art and is:

(1) Through the use of driving steel plate columns and pulling out wooden piles with collars, the entire pile pulling process is fast and convenient, and the pile pulling efficiency is high.

(2) Small requirements for the area of the site.

(3) The cost of pulling out piles is cheap.
