Description

SMW construction method pile shaped steel positioning fixture Technical Field The utility model relates to the technical field of pile section steel positioning by an SMW construction method, in particular to a pile section steel positioning fixture by the SMW construction method. Background The SMW construction method is to drill to a certain depth on site by a multi-shaft type drilling mixer, and to spray out cement-based reinforcing agent at the drill bit to repeatedly mix and mix with foundation soil, and to adopt overlapping construction between the construction units, then to insert H-shaped steel or steel plate as stress reinforcing material before the cement-soil mixture is hardened, to harden the cement, thus forming a continuous and complete seamless underground wall with certain strength and rigidity. In the prior art, when the section steel is inserted into the cement mixing pile, the construction precision and the reliability cannot be guaranteed by means of adjustment of constructors, the distance between the section steel is uneven, the section steel is easy to deflect, the overall quality and the reliability are affected, and the section steel is not attractive. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a pile profile steel positioning fixture for an SMW construction method. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The SMW construction method pile profile steel positioning fixture comprises a foundation and profile steel, wherein a cement soil stirring pile is arranged on the foundation, the profile steel is embedded into the upper part of the cement soil stirring pile, a positioning device is arranged on the upper side of the profile steel, the positioning device comprises a steel bar and a positioning steel plate, and a laser positioner is arranged on the foundation; The laser locator includes casing, slide rail and laser shot-light, the casing bottom is equipped with the inserted bar, be equipped with the lamp stand on the slide rail, the laser shot-light is connected with the lamp stand, lamp stand one side is equipped with the locker. Preferably, the cement mixing piles are provided with a plurality of groups, the arrays are arranged on the foundation, and the section steel is correspondingly arranged with the cement mixing piles. Preferably, the upper side of the positioning steel plate is fixedly connected with the steel bar, and the positioning steel plate is provided with a plurality of groups and respectively props against two side walls at the top of the section steel. Preferably, the steel bar is provided with a connecting sleeve, and the steel bar is connected with the connecting sleeve through threads.
