Deep foundation pit bottom plate concrete pouring system with multiple supporting beams and construction method thereof

Abstract

The invention relates to a deep foundation pit bottom plate concrete pouring system with multiple supporting beams and a construction method thereof. The concrete pouring system comprises a first cantilever bracket, at least one second cantilever bracket, a third cantilever bracket, an unloading hopper, a vertical concrete conveying pipe, a discharge hopper and a horizontal concrete conveying pipe, wherein the first cantilever bracket is fixed to an inner side of the upper supporting beam in an overhanging mode, the second cantilever brackets are fixed on the inner side of at least one supporting beam in the middle in a one-to-one overhanging mode, the third cantilever bracket is fixed on the inner side of the lower supporting beam in an overhanging manner, the unloading hopper is arranged at the overhanging end of the first cantilever bracket, the vertical concrete conveying pipe is fixed to overhanging ends of all the second cantilever brackets, an inlet of the vertical concrete conveying pipe communicates with an unloading opening of the unloading hopper, the discharge hopper is arranged at the overhanging end of the third cantilever bracket, a feeding port of the discharge hopper communicates with an outlet of the vertical concrete conveying pipe, and the horizontal concrete conveying pipe is supported at the bottom of a foundation pit through a plurality of adjusting supports with different heights, an inlet of the horizontal concrete conveying pipe communicates with a discharge port of the discharge hopper, and an outlet of the horizontal concrete conveying pipe points to a to-be-poured point. According to the concrete pouring system, the occupation of a construction site is reduced, and the problems caused by a small construction site are solved.

Description

technical field [0001] The invention relates to the field of construction engineering foundation pit construction, in particular to a multi-support beam deep foundation pit floor concrete pouring system and a construction method thereof. Background technique [0002] With the continuous development of the construction engineering industry, the depth of the foundation pit is getting deeper and deeper, and the geological conditions are more complex, which puts forward higher requirements for the support structure and internal support system. At present, ultra-deep foundation pits in riprap landfill areas generally adopt the support form of "ground connection wall + steel column + concrete support", and the number of support layers is usually more, and most of them are "ring support + straight support + diagonal support + Plane layout form of plank support. The complex support system brings great difficulties to the use of the sky pump for pouring. The arm of the sky pump is d...
