Description

A kind of broken pile treatment device of cast-in-situ bored pile
Technical field
This utility model belongs to bored concrete pile technology field, is specifically related to the broken pile treatment device of a kind of cast-in-situ bored pile.
Background technology
Along with the high speed development of engineering construction, bored pile foundation is widely used, due to cast-in-situ bored pile Basis belongs to underground concealed engineering, and working procedure is more, in order to ensure that quality it requires construction process linking closely, but is subject to The impact of the factors such as geological conditions, construction management, the situation having broken pile in work progress unavoidably occurs, broken pile treatment ratio More difficult, have a strong impact on the duration, the device of broken pile treatment disclosed in existing two kinds, open (bulletin) number CN203200752U public affairs The broken pile treatment device of the cast-in-situ bored pile opened, and the disconnected of cast-in-situ bored pile disclosed in (bulletin) number CN203213105U is disclosed Stake processor, both processing meanss be all utilize openable by four pieces of hinged taper tetrahedrons constituted of side plate, wherein One is to utilize rubber band to fix four blocks of side plates, and another is that four blocks of side plates fixed by the reinforcing bar utilizing simple welding, again waters During concrete, washing side plate open by the deadweight of concrete and make taper tetrahedron open, all there is taper tetrahedron and opens in two kinds of devices After still concrete can be formed the problem of resistance, affect concrete flow velocity, the speed of reduction placing concrete, and rubber band Elastic force and the simple welding pouring degree of depth being required for according to concrete of reinforcing bar carry out accurate calculation, welding operation difficulty is very big.
Summary of the invention
The purpose of this utility model is to solve the problem that above-mentioned existing broken pile treatment device exists, it is provided that a kind of The broken pile treatment device of cast-in-situ bored pile, its technical scheme is as follows:
The broken pile treatment device of a kind of cast-in-situ bored pile, it comprises a center steel reinforcement cage, and the external diameter of center steel reinforcement cage is wanted The internal diameter of original steel reinforcement cage less than in stake holes, center steel reinforcement cage carries out reinforcement in broken pile position in inserting original steel reinforcement cage;Enclose Be provided with the strut of one group of arc around center steel reinforcement cage, one group of strut is including at least three struts, and strut is also adopted by reinforcement fabrication, One group of strut is arranged on the position of more than the center of gravity of steel reinforcement cage, and the lower end of every strut is welded with center steel reinforcement cage, every strut Upper end expand laterally, the maximum outside diameter that one group of strut surrounds should be greater than the internal diameter of original steel reinforcement cage, and center steel reinforcement cage inserts During original steel reinforcement cage, owing to reinforcing bar has elasticity, strut interior can be received and be supported on original steel reinforcement cage, and to have downwards Pressure just can move down, move down and eliminate downward Center of Pressure steel reinforcement cage when putting in place and protect under the supporting role of strut Hold stop;The axial line of a dish-shaped iron block, the axial line of iron block and center steel reinforcement cage it is internally provided with at center steel reinforcement cage Overlapping, the center of gravity position below of the centrally disposed steel reinforcement cage of iron block, iron block connects reinforcing bar Lai Yu center steel reinforcement cage by many Welding, the diameter of iron block should be greater than the external diameter of tremie, and when tremie inserts stake holes, its lower end withstands on the upper of iron block Surface, while center steel reinforcement cage is applied downward pressure, iron block forms closure to tremie, prevents mud etc. from entering Entering, in order to prevent from occurring between tremie and iron block displacement of breakking away, the upper surface at iron block welds a sleeve pipe, to coagulation Soil conduit positions, tremie be inserted to irrigate but in the concrete layer of ot-yet-hardened after, then be lifted up suitably Distance, center steel reinforcement cage can't be lifted up with tremie, just can start concrete perfusion again.
The beneficial effects of the utility model are: use this device to process disconnected post, the most there is not existing broken pile treatment dress The problem putting existence, and reinforcement can also be carried out in broken pile position, it is ensured that construction quality, and construction technology is simple, it is easy to behaviour Make.
