Supporting device for installing cast-in-situ bored pile concrete pouring guide pipe and using method of supporting device

Abstract

The invention provides a supporting device for installing a cast-in-situ bored pile pouring guide pipe and a using method of the supporting device. The supporting device comprises a fixing cover, a circular supporting plate, a guiding mechanism and a guide pipe positioning mechanism, at least two sets of telescopic supporting plates and a plurality of positioning inserting rods are arranged at a cover opening of the fixing cover, a guide pipe inlet is formed in the upper surface of the fixing cover, and the circular supporting plate is rotationally installed at the guide pipe inlet in the top face of the fixing cover through a positioning bearing. A guide pipe positioning hole is formed in the circular supporting plate, the positioning mechanism is installed in the guide pipe positioning hole, and the guide pipe guiding mechanism comprises a first guide wheel assembly and a second guide wheel assembly which are symmetrically arranged on the two sides of the guide pipe positioning hole. The guide pipe can be conveniently limited while moving up and down in the fixing cover, it is guaranteed that the concrete pouring process of the guide pipe is smoothly and stably carried out, the positioning process of the concrete guide pipe is convenient and fast, and meanwhile the device is stably placed to support and limit the guide pipe.

Description

technical field [0001] The present invention relates to the field of construction of bored piles, and more particularly, to a support device used for the installation of concrete pouring pipes of bored piles and a method of using the same. Background technique [0002] A cast-in-place pile is a pile structure formed by in-place holes and pouring concrete or reinforced concrete. Existing cast-in-place piles mainly include bored cast-in-place piles, immersed cast-in-place piles, or blast-expanded cast-in-place piles that use explosives to form an enlarged head at the bottom of the pile hole to increase the bearing capacity; It is formed by pouring concrete into holes in situ. There is no vibration and soil squeeze during construction, but the settlement of the pile is slightly larger. Immersed pipe cast-in-place piles are made by hammering or vibrating a steel pipe with a reinforced concrete pile shoe (pile tip) or a valve type pile shoe into the soil, and then pouring concre...

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a support device for the installation of bored cast-in-situ pile pouring conduits and its use method. The tools or sundries that appear when the cable is pulled and positioned or the workers are used to support the operation are easy to enter the steel cage, which leads to the problem that the overall operation is not stable and safe.
