Problems solved by technology

The grout stop belt is a flexible and impermeable material with low rigidity. When the concrete is poured, the horizontal grout stop belt is easy to bend and shift under the impact of its own weight, concrete or other external forces, which cannot form a good closed irrigation area and loses the closed grout stop. As a result, the concrete grouting in the later stage will cause leakage between the grouting areas, which will seriously affect the grouting quality of the grouting area, and then affect the quality of the project.

Embodiment Construction

[0022] Such as figure 1 As shown, a method of burying a fixed horizontal grout stop includes the following steps:

[0023] 1) The steps of making the ribs 3 and the Ω-shaped enclosure 7,

[0024] According to the size of the horizontal slurry stop 1, make " ”-shaped clamping bar 3, making Ω-shaped enclosure 7 and welding its two ends with template vertical enclosure 6; ensuring that clamping bar 3 can clamp one end of the horizontal grout stop; In addition to being flat and firmly installed in the groove, it must also have a certain rigidity, which can meet the requirements for fixing the formwork at one place of the horizontal grout stop belt;

[0025] 2) Steps for installing the horizontal grout stop 1, template 4 and Ω-shaped enclosure 7,

[0026] According to the design and construction process requirements, first install the formwork 4 at the bottom of the horizontal grout stop 1 on the side of the post-casting block, and then install the horizontal grout stop 1, whi...

Abstract

The invention discloses a method for embedding and fixing a horizontal grout stop belt, relating to a concrete construction method. The strength of the horizontal grout stop belt is increased by arranging reinforcing ribs and omega-shaped walings on the horizontal grout stop belt at intervals so that the horizontal grout stop belt can not deform, bend and displace in concrete pouring, the embedding quality of the grout stop belt is ensured, the difficulty of later joint grouting construction is reduced, the mutual leakage of grouting areas in later concrete grouting is reduced and the grouting quality of the grouting areas is ensured. The method for embedding and fixing the horizontal grout stop belt has the advantages of easy operation, low cost and high reliability.

Description

Technical field [0001] The invention involves a concrete construction method, especially a method of buried a fixed horizontal slurry zone. Background technique [0002] In the concrete engineering of aquatic structure, it is generally divided into dam and block construction. There are different seam irrigation areas between the dam blocks.The seams of the dam are surrounded into a closed area with closed.The stopplasia belt is a flexible impermented material. Its rigidity is small. When the horizontal stopbus is poured in concrete, it is easy to bend and displays under the impact of self -weight, concrete or other external forces.The effect caused the irrigation area to leak each other during the concrete grouting area in the later period, which seriously affected the grouting quality of the irrigation area and then affected the quality of the project. Invention content [0003] The technical problem to be solved by the present invention is to provide a method of buried a fix...
