Abstract

The invention relates to the technical field of building construction, in particular to a building pile foundation construction method. Comprising the following steps that S1, surveying and setting out are conducted, a foundation is leveled, and the position of a pile foundation is marked; s2, a mud pit is dug between the pile holes, and drainage grooves are dug around the pile holes; s3, lowering and mounting the pile casing; s4, slurry is poured into the pile hole; s5, the positions of coordinate points and the drilling sequence are determined, and a drilling operation rack used for supporting a drilling machine is laid on the construction plane of the building pile foundation; s6, drilling is conducted; s7, hole cleaning; s8, lowering a reinforcement cage; s9, after hoisting of the reinforcement cage is finished, concrete pouring is conducted; and S10, after initial setting of the concrete, the pile casing is pulled out of the pile hole, and a pile foundation is formed. The construction method is convenient to operate, high in construction speed, capable of saving materials and obvious in economic benefit, and construction efficiency is improved while pile foundation construction quality is guaranteed. The method is mainly applied to the aspect of building pile foundation construction.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically, to a construction method for building pile foundations. Background technique [0002] Pile foundation construction is required before building construction begins. However, the construction environment is often complex and diverse, and the construction environment puts forward higher technical requirements for construction technology. The common construction environment conditions are close to residential areas, soft land, poor geological conditions, dense karst caves and other construction problems. The pile foundation construction method in the prior art is relatively complicated, and different equipment needs to be used for different rock formations, the work efficiency is low, and the economic cost is high. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a constru...
