Embodiment Construction

[0033] In order to further understand the invention content, characteristics and effects of the present invention, the installation of the side wall formwork at the construction joint of the caisson is taken as an example, and the detailed description is as follows in conjunction with the accompanying drawings:

[0034] (1) The foundation of the caisson is a reinforced concrete structure, the foundation depth is 13.95m, the foundation size is 13.65×12.65m, and the foundation structure adopts C45 grade waterproof and impermeable concrete. According to the design requirements, the caisson shall be constructed in three sections, and construction joints 1 shall be set at the 300~500mm wall part above the bottom plate and the sectioned pouring part of the wall. The construction joint 1 is stepped, and is composed of a "convex"-shaped construction joint 1-1 and a "one"-shaped construction joint 1-2. The "convex"-shaped construction joint 1-1 is set on the water-facing side of the wa...

Abstract

The invention discloses a construction gap of an underground waterproof concrete structure and a wall template installation method thereof. Aiming at the technical problem that a wall template of a ladder-shaped construction gap is difficult to install and easy to deform, on the basis of a novel ladder-shaped construction gap, short wood beams are used for controlling forming of the construction gap, the template is fixed by a split boltwith reserved threads secondarily, numerous specific construction measures of a reinforced steel bar blocking foot fixed on a base plate, a transom arranged on the split bolt and the like reduce wall surface construction gaps, improve impression quality of concrete surface, improve anti-permeability capacity of the waterproof concrete structure, reduce leakage of buildings, guarantee that the structure is more stable, controlsectional dimension of a wall body, prevent the wall body from deforming, guarantee construction quality, is simple and easy inconstruction operation, improve working efficiency, and reduce construction cost.

Description

technical field [0001] The invention relates to a construction method of a waterproof concrete structure, in particular to a construction joint in an underground waterproof concrete structure and a construction method of a structural template at the construction joint. Background technique [0002] In order to ensure the appearance quality of the concrete structure, a new type of construction joint is usually used in the construction of the underground waterproof concrete structure. Set horizontal construction joints within 3 / 4 of the water surface, and 300mm to 500mm higher than the previous construction joints, set vertical construction joints in the middle, and set steel water stop plates in the middle of 3 / 4 horizontal construction joints. [0003] Using the construction method of the above-mentioned concrete structure construction joint, because the construction joint is stepped, the wall is poured in sections, which makes it difficult to support the side wall formwork ...
