Assembly recoverable retaining wall support system

Abstract

The invention discloses an assembly recoverable retaining wall support system. The assembly recoverable retaining wall support system comprises a retaining wall unit. The retaining wall unit is composed of at least two retaining wall assemblies which are fixedly connected. The assembly recoverable retaining wall support system has the technical effects that the device is assembly steel retaining wall support, and in the hole digging construction of a digging pile, the device can play a role in supporting a hole wall and can also serve as a concrete retaining wall formwork. By means of the device, a concrete digging hole and a concrete retaining wall can be continuously constructed, the construction of a next retaining wall can be carried out without waiting that the concrete strength meetsthe design requirement, the digging progress of a concrete pile is accelerated, the pile bottom designed elevation can be continuously constructed, and meanwhile the safety and the stability of the hole wall during pile digging are guaranteed.

Description

technical field [0001] The invention relates to a retaining wall supporting structure of an artificial hole-digging pile, in particular to an assembly recovery type retaining wall supporting system. Background technique [0002] The traditional manual excavation pile construction has the disadvantages of slow construction speed and poor construction safety, which is mainly reflected in the fact that the reinforced concrete retaining wall needs to be constructed in sections, and in order to ensure safety, each section is relatively short, and the next section must be constructed after the previous section reaches the design strength . Steel casings can be used instead of reinforced concrete retaining walls, but for harder soil layers, steel casings are difficult to press down; and when the pile length is too long, steel casings are difficult to take out and cannot be reused, and the construction cost is quite high. high. [0003] The invention mainly solves the problem of l...

[0002] The traditional manual excavation pile construction has the disadvantages of slow construction speed and poor construction safety, which is mainly reflected in the fact that the reinforced concrete retaining wall needs to be constructed in sections, and in order to ensure safety, each section is relatively short, and the next section must be constructed after the previous section reaches the design strength

Steel casings can be used instead of reinforced concrete retaining walls, but for harder soil layers, steel casings are difficult to press down; and when the pile length is too long, steel casings are difficult to take out and cannot be reused, and the construction cost is quite high. high

[0003] The invention mainly solves the problem of long retaining wall construction period in the construction process of manual excavation piles. The use of recyclable steel structure retaining wall support system can shorten the construction period and solve the high cost problem caused by the non-reusable use of traditional steel retaining cylinders.
