Steel guide wall used for secant pile hole construction

Abstract

The invention relates to the technical field of building construction, in particular to a steel guide wall used for secant pile hole construction. At least four locating hole groups are arranged on two oppositely arranged longitudinal beams in an equally spaced manner; each locating hole group comprises at least three locating holes; at least four limiting cross beams are connected to positions, corresponding to the locating hole groups, between the two longitudinal beams to surround at least three square holes; by using fastening pieces, the limiting cross beams are connected to the longitudinal beams through a locating hole; anchor piles are fixedly arranged on the external sides of the two longitudinal beams; and therefore, during secant pile hole construction, a purpose of enabling secant pile hole to be located and occluded with each other is realized only by using the anchor piles to fix the steel guide wall on the operation ground, and then using the square holes to form first secant pile holes in a spaced manner and adjusting the limiting cross beams to be tightly connected with different locating holes in the locating hole groups to form second secant pile holes between the adjacent first secant pile holes.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel guide wall used for hole-forming construction of occlusal piles. Background technique [0002] At present, in the construction of occlusal piles, in order to ensure accurate positioning of occlusal piles, mutual occlusal, control the occlusal depth between piles, and meet the construction quality requirements, before drilling occlusal piles, construct the guide wall according to the designed pile position and axis. Control the pile position, pile axis, occlusal depth, etc. Generally, the guide wall adopts a 200mm thick, C30 plate-type reinforced concrete structure, which is easily damaged during construction, and the reinforced concrete structure cannot be reused, and the construction cost is high. Unwanted to see. Contents of the invention [0003] Aiming at the above-mentioned problems, the present invention discloses a steel guide wall for occlusal pil...
