Hoisting device and hoisting process for cast-in-place pile construction in narrow space

Abstract

The invention provides a hoisting device and a hoisting process for cast-in-place pile construction in a narrow space, and belongs to the technical field of cast-in-place pile construction.The hoisting device comprises a moving trolley, a hoisting machine, a hoisting frame and a controller, and the hoisting machine is connected to the moving trolley and provided with a hoisting rope suitable for connecting and hoisting multiple sets of reinforcement cage sections; the hoisting machine is suitable for sequentially hoisting multiple sets of reinforcement cage sections and moving the reinforcement cage sections into a pile hole, the upper end of the hoisting frame is used for being detachably connected with a hoisting rope of the hoisting machine, the lower end of the hoisting frame is used for being detachably connected with multiple vertically-arranged reinforcing steel bars on the reinforcement cage sections, and the controller controls the moving trolley and the hoisting machine to operate. The hoisting device and the hoisting process for construction of the cast-in-place pile in the narrow and small space have the technical effects that multiple groups of reinforcement cage sections can be sequentially hoisted into a pile hole in the narrow and small space, large hoisting equipment does not need to be used, operation is convenient in the construction process, the hoisting frame and the reinforcement cage sections are stably connected, and the hoisting speed, the hoisting progress and the hoisting efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of cast-in-place pile construction, and in particular relates to a hoisting device and a hoisting technique for cast-in-place pile construction in a narrow space. Background technique [0002] The cast-in-place pile is a common pile structure, which needs to be drilled, hoisted, and poured concrete in sequence. Its cross-section is generally circular. With the rapid development of urban underground transportation, for cast-in-place piles constructed in a small underground space, the steel cage needs to be hoisted into the pile hole during construction. For the overall reinforcement cage formed by the combination of cage segments, during hoisting, multiple groups of reinforcement cage segments need to be hoisted into the pile holes in turn and connected in sequence, and finally the overall reinforcement cage is formed. Due to the construction work in a narrow space, it is inconvenient to use the existing lar...

AI Technical Summary

Problems solved by technology

Due to the construction work in a narrow space, it is inconvenient to use the existing large hoisting equipment to hoist the steel cage section, and the operating height of the hoisting equipment is high, and the hoisting height of the steel cage section will be limited by the narrow space. It is also inconvenient, which will affect the overall construction progress and efficiency of cast-in-place piles
