Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of SMW method pile verticality control, and particularly relates to a SMW method pile profile steel verticality control device. BACKGROUND

[0002] SMW method continuous wall was invented in 1976. The SMW method is that a multi-shaft drilling and mixing machine drills and mixes on site to a certain depth, a cement-based reinforcing agent is sprayed at the drill bit to repeatedly mix with the ground soil, overlapping and lapping construction is adopted between each construction unit, then H-shaped steel or steel plate is inserted as stress reinforcement material before the cement soil mixture is hardened, and a continuous, complete and jointless underground wall body with certain strength and rigidity is formed after the cement is hardened. The most commonly used SMW method is a three-shaft drilling and mixing machine, in which the drill rod is used for cohesive soil and for sandy soil and bedrock, and other machine types are also developed for construction under urban viaducts, space-limited occasions, or for building walls under the sea or reinforcing soft ground.

[0003] The construction sequence generally includes trench excavation (determine whether there are obstacles and make a slurry trench) -> place the guide rail -> set the construction mark -> SMW drilling and mixing (drilling and mixing, repeated mixing, mixing when lifting) -> place the stress reinforcement material (H-shaped steel) -> fix the stress reinforcement material -> complete the SMW construction; although the SMW method has various problems and focuses of attention in application, as a new technology for popularization and application, under the premise of meeting the engineering technical requirements, the SMW method has incomparable advantages as a retaining structure compared with underground continuous walls and bored piles with waterproof curtains as retaining structures.
