Description

Drilling machine for anti-floating anchor rod construction and use method thereof Technical Field The invention relates to the technical field of drilling machines for anti-floating anchor rod construction, in particular to a drilling machine for anti-floating anchor rod construction and a use method thereof. Background As urban population increases, urban land becomes more and more intense, so a large number of underground shops, underground parking garages, subways and multi-layer basements emerge, and with this, groundwater buoyancy problems, particularly in coastal areas, have not been neglected. The prior anti-floating measures mainly comprise a drainage-lowering water-intercepting method, a weight-pressing method, a pile-pulling-resistant method and an anti-floating anchor rod method. Anti-floating anchors have been widely used in many areas as a new anti-floating technique. In recent years, with the increasing growth of high-rise buildings, more and more groundwater anti-floating problems are put in front of us, so that the research and application of the anti-floating anchor technology have very important significance (the research and engineering application of the anti-floating anchor mechanical property, jiang Jibao, guizhou university, 2015). The anti-floating anchor rod refers to a structural member which is arranged against the upward displacement of a building on the anti-floating anchor rod, and is related to the height and the change condition of the underground water level and is opposite to the stress direction of the anti-floating pile. The anti-floating anchor rod is different from a common foundation pile, has own unique performance, and is the biggest difference from the common foundation pile in that the foundation pile is a compression-resistant pile, the pile body bears building load pressure, the stress is transferred from the pile top to the pile bottom, the pile body stress changes along with the change of building load, the anti-floating pile is a pulling force born by the anti-pulling pile body, the stress of the common anti-floating pile also is transferred from the pile top to the pile bottom, the pile body stress changes along with the change of the groundwater level, but the stress mechanisms of the pile body and the pile body are just opposite. In short, the anti-floating anchor rod utilizes the tensile force generated by the tensile strength of the anchor rod and the pulling resistance generated by the friction force between the anchor rod and the soil layer to restrain the floating trend of the foundation, thereby playing the role of resisting the floating of the foundation. In the prior art, some schemes are proposed about the construction process of an anti-floating anchor rod, such as the construction method of the anti-floating anchor rod disclosed in the invention patent with the publication number of CN105350584A, the scheme is that after the cushion layer is constructed, cushion layer concrete at the pile position of the anti-floating anchor rod is cut by a water drill, the cushion layer upper anchor rod Kong Sizhou is used for piling a cofferdam by using red sandstone, then a channel is paved by the red sandstone for connecting the cofferdam to the nearest column cap pit, an anchor rod hole is drilled on the red sandstone natural basis by using an anchor rod rotary spraying drilling machine, prestressed concrete is used as an anti-floating anchor rod body, two ends of the anchor rod body are connected with prestressed nuts by using square steel backing plates, grouting pipes are placed into the anchor rod hole together with the pre-floating anchor rod body, grouting is performed by adopting a secondary grouting method, the opening of the anchor rod hole is plugged by adopting modified asphalt, the construction of a waterproof layer is performed above the anchor rod hole, and the upper end of the anti-floating anchor rod body is anchored in a foundation auxiliary assembly. The scheme solves the problem of anti-floating construction of the structure in the red sandstone geology with rich groundwater level. In addition, the tobacco station engineering investigation limited company provides a construction method of an anti-floating anchor rod and a special long spiral drilling machine (with the publication number of CN 101914915A), the long spiral drilling machine is used for replacing a traditional hydraulic anchor rod drilling machine or a rotary drilling machine to carry out anti-floating anchor rod construction, the long spiral drilling machine is transformed to enable the long spiral drilling machine to carry out small-aperture drilling construction and high-pressure grouting, the characteristics of high construction speed of the long spiral drilling machine, dry pore-forming, self hoisting of the anchor rod and the like are fully utilized, the construction efficiency of the anti-floating anchor rod is improved by more than ten times, no mud pore-forming is car
