Field prefabricated channel

Abstract

The invention discloses a field prefabricated channel. The field prefabricated channel comprises C-shaped mound plates, wherein a bottom plate is connected between the C-shaped mound plates, the two ends of the C-shaped mound plates are provided with splicing mechanisms, and each splicing mechanism comprises a first splicing plate, a connecting hole, a second splicing plate, a labyrinth water stopgroove and an n-shaped expansion joint; each first splicing plate and the corresponding second splicing plate are occluded with each other, thereby facilitating the end-to-end connection and fixationof the C-shaped mound plates; a labyrinth type water stop band is formed in the labyrinth water stop groove, thereby being conductive to improving the anti-seepage effect of the splice of the C-shaped mound plates; the n-shaped expansion joints at the joints of the first splicing plates and C-shaped mound plates are used for compensating the temperature deformation to avoid the deformation and damage of the joint of the two C-shaped mound plates; during installation, the backfilling end faces of the bottom ends of the C-shaped mound plates are buried into the ground to form a channel foundation, which does not need assisting of soil bases at the two sides and is not affected by the deformation of the soil bases, the top ends of the C-shaped mound plates are walkable end faces, and a continuous walking channel is formed after the installation is completed.

Description

technical field [0001] The invention belongs to the technical field of water conservancy channels, and in particular relates to a field prefabricated channel. Background technique [0002] Field channels can be divided into prefabricated channels with integral section and detachable prefabricated channels. Both structures are attached to the soil foundation and based on the soil foundation. The prefabricated channels with integral section have various sections of cement products or other material products. , the common feature is that there is no interface on the section. During construction, the soil foundation needs to be shaped and compacted, and then the product is paved. Among them, cement products generally need to be equipped with geomembrane anti-seepage, and the detachable prefabricated channel can be decomposed into the outer channel. Panels, inner panels, bottom panels and top channel panels. During construction, the soil foundation is first shaped, and then all ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a prefabricated canal in the field. By burying part of the slabs underground, the canal foundation is formed to solve the above-mentioned background technology. Soft, high moisture content, difficult to tamp, and the soil foundation of the field channel will be deformed irregularly under the action of freezing and thawing, causing the channel to bend, cross-sectional shape change, skew, and even fracture and subsidence
