Abstract

The invention relates to the field of constructional engineering, in particular to an environment-friendly cast-in-place pile construction device for constructional engineering. The technical problems that the construction steps of a cast-in-place pile divided into an inner layer and an outer layer are tedious, and the bearing capacity and the service life of the cast-in-place pile are affected if gravel materials forming an outer column layer of the cast-in-place pile are not evenly dispersed are solved. The environment-friendly cast-in-place pile construction device for constructional engineering comprises a filling unit, a vibration distribution unit and the like. And the upper side of the filling unit is connected with a vibration distribution unit for uniformly distributing crushed stone materials. The isolation type pouring component is arranged, the inner column layer is poured out in a layer-by-layer pouring mode, the outer layer is obtained through overflowing, meanwhile, gravel materials are evenly scattered in slurry of the outer layer through the gravel material dispersing component to form the outer column layer, then the heights of the inner column layer and the outer column layer are sequentially increased, and the inner column layer and the outer column layer are evenly poured out. And rising power is converted into rotating force for uniformly scattering materials, so that the gravel materials are dispersed in slurry of an outer column layer in time.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an environmental protection cast-in-place pile construction device for construction engineering. Background technology [0002] In the foundation construction site of construction engineering, cast-in-place piles need to be driven several meters to tens of meters below the bottom layer. The cast-in-place pile construction technology is a concrete technology with low construction cost and simple operation, that is, the concrete slurry penetrates into the depth of the stratum, which can closely combine the stratum with the cast-in-place pile, play a good role in infiltration, compaction and splitting of the stratum, and the interaction between the three can make the stratum more stable. [0003] The existing cast-in-place pile has an internal and external structure. The inner column layer on the inner side is poured by mud alone, while the outer column layer on the outer side is ...
