Description

Lattice column positioner for bored pile Technical Field The utility model relates to the technical field of cast-in-situ pile construction, in particular to a lattice column positioner for a cast-in-situ bored pile. Background The construction of the inner support filling pile and lattice column combined structure is an energy-saving and environment-friendly construction process which is gradually popularized in the national construction industry at present, namely, according to the requirements of foundation pit supporting drawings and upper structure design drawings, the lower part of a foundation slab adopts a filling pile mode, the upper part of the foundation slab adopts a steel structure lattice column as an inner support beam column, the lattice column bears the load of an upper inner support beam, the independent height can reach 13-20 m, and the foundation slab can be recycled. In the conventional construction process, the lower part of the lattice column is required to be inserted into the cast-in-place pile reinforcement cage for 3 meters, and a conduit is arranged in the lattice column during casting, so that the casting flow is consistent with that of underwater concrete. Corresponding positioning devices are not arranged in the current construction process, after the lattice column bored pile adopts mechanical pore forming, a reinforcement cage is arranged under the lattice column bored pile, concrete of the lower portion bored pile is poured to the elevation, and a crane is used for hoisting the lattice column to the position of about 3m in the bored pile. In the conventional process flow, the lifting and positioning of the lattice column is controlled only by the operator on the upper part of the orifice, the deviation and the angle deviation of the lattice column of the cast-in-place pile are difficult to control, and the construction quality cannot be effectively ensured only by the experience of the operator on the spot and the cooperation mercy degree of a crane driver. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a lattice column positioner for a bored pile. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a drilling bored concrete pile lattice post locator, includes lattice post and locating platform, the locating platform side is equipped with adjusts the stabilizer blade, be equipped with strip formula spirit level and lug on the locating platform, the locating platform upside rotates and is equipped with the revolving stage, locating platform and revolving stage middle part are equipped with the round hole that holds the lattice post, the revolving stage round hole inboard is equipped with the hydro-cylinder, the hydro-cylinder is equipped with the multiunit, and corresponds the setting with the lattice post, hydro-cylinder one end is equipped with the slipmat, slipmat offsets with the lattice post lateral wall, the locating platform upside is equipped with the stopper, the stopper includes guide bar and magnetic sheet. Preferably, the adjusting support leg comprises a telescopic rod and a base plate, the upper end of the telescopic rod is connected with the rotary table, and the lower end of the telescopic rod is connected with the base plate. Preferably, the strip type level gauge is provided with a plurality of groups which are uniformly arranged on the upper side of the positioning table, and the plurality of groups of strip type level gauge are longitudinally and transversely arranged.
