Problems solved by technology
[0004] The purpose of this application is to provide a construction method pile center positioning auxiliary device and a construction method pile center positioning method to solve the problem in the prior art that artificially controlling the vertical placement of straight rods to locate the pile center plane position is easy to cause positioning errors. When the accuracy is improved by reducing the distance between the positioning string and the pile center, the spilled slurry of the stirring pile and the stirred soil dropped by the drill pipe may damage the positioning string, and the technical problem of placing and moving the profile steel is more troublesome when using parallel profile steel for positioning

The invention relates to the technical field of building construction, in particular to a soil mixing wall pile core positioning auxiliary device and a soil mixing wall pile core positioning method. The soil mixing wall pile core positioning auxiliary device comprises a positioning rack, a supporting rack and a positioning rope, wherein one end of the positioning rack is used for being connected to a protection barrel of a stirring pile machine inside a guiding groove, the other end of the positioning rack is provided with two hanging points, and the two hanging points are hung with hanging hammers correspondingly; the positioning rope is arranged on the supporting rack and is provided with a length framing mark; and projections of the two hanging hammers in the perpendicular line directions of the hanging hammers fall at two corresponding ends of the framing mark correspondingly. According to the soil mixing wall pile core positioning auxiliary device and the soil mixing wall pile core positioning method, by means of the arrangement of the positioning rack, outside-put lead-out of a pile core is realized, damage of spilled slurry to the positioning rope is avoided, and then the accuracy of positioning the pile core using the positioning rope again is guaranteed; in addition, positioning the pile core adopting a straight rod is avoided, and the soil mixing wall pile core positioning auxiliary device and the soil mixing wall pile core positioning method are less affected by artificial placement and other factors; and in addition, the soil mixing wall pile core positioning auxiliary device is simple to install, repeated movement adjustment is not needed, and operations are simplified.
Description
technical field [0001] The present application relates to the technical field of building construction, in particular to an auxiliary device for locating the center of a construction method pile and a method for locating the center of a construction method pile. Background technique [0002] At present, SMW construction method piles are also called stiff cement-soil mixing pile walls, that is, steel materials such as H-shaped steel are inserted into cement-soil mixing piles to form a continuous, complete, seamless underground wall with certain strength and rigidity. , so that it has two functions of force bearing and impermeability at the same time. When its enclosure function is completed, the section steel can be pulled out and reused. [0003] In the construction of SMW piles, the rapid and precise control of the position of the mixing pile core is a difficult problem for construction companies. Specifically, there are two commonly used methods for pile core positioning...
