Deep foundation pit earthwork vertical soil sampling equipment

Abstract

The invention discloses deep foundation pit earthwork vertical soil sampling equipment. The equipment comprises attached pieces fixed to a foundation pit supporting structure or a retaining structure,a framework vertically stretching into a foundation pit and mounted on the attached pieces, a lower roller arranged at the bottom of the framework, two upper rollers arranged at an outlet of the foundation pit, a driving mechanism driving the upper rollers to rotate, and a traction chain wound on the lower roller and two upper rollers in a closed mode, hoppers uniformly distributed on the traction chain, a chute located between the two upper rollers, and a soil connecting tank connected with the tail end of the chute. The upper rollers can drive the traction chain to move while rotating, theedges of openings of the hoppers are hinged to the traction chain, the openings of the hoppers on the rising side of the traction chain face upwards, the openings of the hopers on the falling side face downwards, the hoppers can sample soil when winding across the lower roller and can pour the sampled soil into the chute when winding across the first upper roller, efficient vertical transporting of deep foundation pit earthwork is achieved through the equipment, a required operating surface is small, the transporting efficiency is high, the structure is simple, and mounting is convenient.

Description

technical field [0001] The invention belongs to the field of deep foundation pit construction, and in particular relates to a vertical earth-taking equipment for deep foundation pit earthwork. Background technique [0002] With the continuous development of building foundation pits to super large areas and super deep depths, soil extraction after excavation of deep foundation pits is very important, which directly affects the progress and economic cost of deep foundation pit projects. The current equipment for earthwork excavation of deep foundation pits includes Long-arm excavators, shell-bucket telescopic-arm excavators, grab excavators, etc., all of these equipment have the problems of large operating surface and low construction efficiency. Contents of the invention [0003] The object of the present invention is to provide a vertical excavation equipment for deep foundation pit earthwork, which realizes efficient vertical transportation of deep foundation pit earthwor...
