Abstract

The invention discloses a construction method for a vertical waterproof construction joint. The construction method comprises the following steps: S1, manufacturing a construction joint template; S2,mounting the construction joint template; S3, carrying out pouring for the first time; S4, preparing pouring for the second time; and S5, carrying out pouring for the first time. A water sealing and seepage resisting effect in a horizontal section and a vertical section is obtained by combining a tooth-shaped joint structural form between new and old concrete and a scabbing process, and a waterproof purpose of a large sized vertical construction joint is guaranteed. A process of combining a conventional aluminum template with construction joint construction is innovated by means of a sustainable utilizing theory of the aluminum template, and the aluminum template is easily processed, formed and manufactured. The template technology is sophisticated in operation and can be utilized sustainably. Use of conventional flexible waterproof and rigid waterproof materials is cancelled, the material cost is saved, and the construction period is shortened. New and old concrete is in contact by using the tooth-shaped joint structure, and the structural contact surface is increased, so that the anti-seizing ability is enhanced.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a construction method for vertical waterproof construction joints. Background technique [0002] In the construction of ultra-thick mass concrete, the "layered and segmented" construction method is often used, which inevitably produces construction joints. For large-area construction joints, it is only possible to adopt high-efficiency, low-cost, and easy-to-operate methods. It is the development trend of mass concrete construction joint treatment. The invention optimizes the construction method of the vertical construction joint of the traditional transfer layer, and adopts a low-cost, recyclable, easy-to-process and easy-to-assemble construction method to solve the problem of super-thick concrete construction joint treatment. [0003] Conventional construction methods for construction joints: [0004] 1. Chiseling method on the surface of the vertical joint: After the co...
