Manufacturing and mounting method and auxiliary mounting device for reinforcement cage in pile hole

Abstract

The invention discloses a manufacturing and mounting method and an auxiliary mounting device for a reinforcement cage in a pile hole. The method comprises the steps as follows: a polygonal mounting rack with supporting legs arranged at all tips is placed at the opening of the dug pile hole, main ribs are gradually placed in the pile hole through guide grooves, and then the main ribs, outer hooping ribs and inner reinforcing ribs are fixedly mounted through soft ropes. The method is simple in construction technology and applicable to mounting of reinforcing steel bars in a large-diameter ultra-deep manually-dug pile, particularly to mounting of the reinforcing steel bars with poor pile hole position conditions or various pile hole size type conditions, and has the very good realistic value.

Description

technical field [0001] The invention relates to an installation method for making a reinforcement cage in a pile hole and an installation auxiliary device thereof, belonging to the technical field of civil construction. Background technique [0002] With the development of the national economy, buildings are becoming more and more high-rise. Manual excavated piles are favored by owners, designers, and construction units for their unique large bearing capacity, simple operation, easy quality assurance, and economical and practical advantages. Combined with national green construction Requirements, taking into account the application of green construction technology, should do a good job in "water saving, land saving, material saving, energy saving, and environmental protection". In construction engineering, steel bar engineering occupies a large proportion, so improving the efficiency of steel bar processing and production can save a lot of manpower, material resources and f...

AI Technical Summary

Problems solved by technology

However, it is very difficult for large-diameter ultra-deep artificial excavated piles and enlarged head steel bar binding construction, which increases labor, machinery and construction period; because the weight of steel bars is generally large and the dynamic friction factor is large, it is difficult to lift and install steel cages. Large, time-consuming, labor-intensive, low-efficiency, and a waste of a lot of human resources when workers carry out steel bar lifting and installation, especially in poor position conditions of hole piles in construction (if transporting steel cages requires a large engineering cost), or the There are many sizes and sizes of regional hole piles. If the existing technology is used to make steel cages on the ground, the project cost will be greatly increased.
