Abstract

The invention discloses a connecting device of a hanging board in a deep foundation pit supporting structure, and belongs to the field of deep foundation pit supporting structures. The connecting device of the hanging board in the deep foundation pit supporting structure is compact in overall structure, the hanging board can be fixed effectively through a supporting mechanism in the using process,a lateral moving mechanism is driven by a transmission mechanism to move, therefore a lateral fitting mechanism is driven to fit the external left and right environments mutually, and the connectingdevice can be fixed well; in the using process, the transmission mechanism can drive a locating mechanism to move, therefore the connecting device is fixed in a pit better and can be effectively fixedwell, the connecting device is firm in connection, and circulation of freezing and thawing of pile spacing in the process of spraying concrete, large-area layering agglomeration and shedding, devastating damage and the problems that vertical surfaces forming pile spacing are quite irregular, and space and positions of expanded grooves are not occupied can be avoided; the cost is low, constructionand installing are convenient, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of deep foundation pit support structure, in particular to a connection device for hanging plates in the deep foundation pit support structure. Background technique [0002] The wall surface formed by the side facade of the pit wall between two adjacent reinforced concrete support piles of the deep foundation pit support structure sprayed with shotcrete is called inter-pile protection. The existing technology of pile inter-protection: all adopt advanced The steel mesh is hung outside, and the method of spraying concrete is completed. When the soil between the support piles in the deep foundation pit support structure is in a wet state, that is, the soil between two adjacent support piles that is below the groundwater level and affected by groundwater, the piles formed by shotcrete are used. During the freezing and thawing season of the inter-wall, large areas of layered agglomeration, falling off and hollowing will a...
