Embodiment Construction

[0017] The method of the present invention can be implemented as long as there are a small amount of shaped steel molds, and the output is determined according to the size of the site. The first semi-U-shaped component is formed by combining two shaped steel molds and can be connected according to the above procedure. Pouring requires skilled processing skills for workers. It mainly refers to concrete mixing, mold assembly and vibrating. The specific production method can be carried out according to the fragmented chain shown in Figure 2.

[0018] Compared with Figure 1 and Figure 2, the lining height of the U-shaped mold is the depth h of the channel, generally 600-900mm, and its arc radius r is in the range of 400-600mm. The elongated part 1 of the template is set in the straight section, and the arc part To shape the mold section 2, there are mold plugs 3 and 4 at both ends of the template. The two plugs can also be made integrally with the template. When chain production is ca...

Abstract

A process for producing the impervious semi-U shaped concrete member used as the liner of irrigation ditch includes such steps as using a finished semi-U shaped as external mould, using a shaped steel mould as internal mould, fixing, pouring concrete into space between them, and isolating the products one by one.

Description

Technical field [0001] The method of the present invention relates to a civil engineering, and is a production method of an anti-seepage lining concrete member for agricultural irrigation and drainage channels. Background technique [0002] With the continuous deepening of water-saving irrigation technology in the comprehensive development of agriculture, concrete U-shaped channels have been widely used in the irrigation areas of rivers and reservoirs due to their anti-leakage, small land occupation, small engineering volume, convenient and quick construction, and frost heave resistance. However, due to the large damage rate during construction and pulling and the large number of molds required during component production, the cost of the semi-U-shaped components produced is relatively high, which affects the promotion and use, naturally, serious water seepage in drainage and irrigation , The problem is not solved well. Summary of the invention [0003] In view of the above prob...
