Embodiment 1
[0029] see figure 1 , the present invention provides a technical solution: a method for installing an underground diaphragm wall mixing pile, comprising the following steps:
[0030] S1: Level the site, remove weeds and sundries on the surface, use backfill cohesive soil and compact it in low-lying areas to meet the bearing capacity of the foundation when the pile driver is running, and for paddy fields, clean the surface 0.3-0.5m after draining , Make the original ground into a 4% transverse slope, and excavate side ditches on both sides of the subgrade, and take protective measures such as marking for the pipelines under the construction site;
[0031] S2: Measurement and stakeout, after using the total station to accurately release the control piles according to the drawings, release the specific pile positions according to the pile location layout, set obvious signs for the control piles, and review them regularly;
[0032] S3: Mix cement slurry. The cement slurry is prep...

The invention discloses an installing method of an underground diaphragm wall stirring pile and belongs to the field of mixing pile installing methods. The installing method of the underground diaphragm wall stirring pile comprises the following steps: S1, leveling a field; S2, measuring and lofting: accurately lofting a control pile according to a drawing by using a total station, then lofting aspecific pile position according to the pile position arrangement, setting an obvious mark for the control pile, and periodically rechecking; S3, mixing cement paste; S4, installing a cement stirringmachine in place; S5, stirring and spraying slurry; S6, lifting and stirring: lifting by a stirrer; S7, closing the stirring machine, and shifting; and S8, detection, and conducting pile forming within 7 d. The installing method is more scientific and reasonable, the problem that uneven settlement is likely to be generated on a soft foundation between the cement mixing pile bodies is solved, the foundation pit construction safety is improved, meanwhile, the using amount of the cement mixing piles is reduced, the construction cost is reduced, and the effects of being simple in structure, easy and convenient to construct and high in efficiency are achieved.
Description
technical field [0001] The invention relates to the field of installation methods of stirring piles, in particular to an installation method of stirring piles in underground continuous walls. Background technique [0002] In recent years, with the continuous development of underground space, as well as the limitations of the surrounding environment and construction sites, underground diaphragm walls have gradually become an effective means of deep foundation construction. The existing installation methods for diaphragm wall mixing piles are relatively complicated to construct and waste materials. , will increase the installation cost of the mixing pile, and the sinking of the mixing pile cannot be avoided. Contents of the invention [0003] 1. Technical problems to be solved [0004] Aiming at the problems existing in the prior art, the object of the present invention is to provide an installation method of the underground diaphragm wall mixing pile. The installation meth...
