Underground engineering reserved deformation joint connecting interface structure and manufacturing method thereof

Abstract

The invention discloses an underground engineering reserved deformation joint connecting interface structure. The underground engineering reserved deformation joint connecting interface structure is characterized in that a groove (3) is formed in a boundary surface of new / old concretes (1 and 2), a left-side steel plate water-stop belt (4) is reserved in the old concrete (2) and positioned at the groove (3), the left-side steel plate water-stop belt (4) is welded with a right-side steel plate water-stop belt (5), the right-side steel plate water-stop belt (5) is positioned in the new concrete (1), a deformation joint (6) is formed in the cross section of the new concrete (1), a detachable water-stop belt (7) which is perpendicular to the deformation joint (6) is arranged in the deformation joint (6), and meanwhile, two ends of the detachable water-stop belt (7) are buried in the new concretes (1) on two sides. The underground engineering reserved deformation joint connecting interface structure has the advantages that adverse problems of a frequently used reserved interface mode are solved, a protection function can be fulfilled well in an early period, construction is facilitated in a later period, construction quality is ensured, and the waterproof performance is good.

Description

technical field

[0001] The invention belongs to the technical field of concrete, and in particular relates to a connection interface structure for reserved deformation joints in underground engineering and a manufacturing method thereof. Background technique

[0002] With the increasing construction of underground projects and the development of urban planning, adjacent underground projects often need to be connected by connecting channels. The construction time of later projects is uncertain. The underground projects constructed in the early stage usually need to reserve connection interfaces to connect with the later underground projects.

[0003] Commonly used reserved interface forms are: 1 reserved deformation joint waterstop + masonry or concrete peripheral protection, this form is easy to damage the waterstop when excavating and removing the peripheral protection in the later stage; 2 reserved deformation joint waterstop + The waterproof concrete of the connecting bod...
