Description

Technical Field

[0001] The present application relates to the technical field of anti-seepage walls, and in particular to a steel guide trough used for the construction of anti-seepage walls. Background Art

[0002] An anti-seepage wall is an underground continuous wall constructed within a loose aquifer or earth-rock dam (weir) foundation to prevent seepage. It is widely used in water conservancy projects both domestically and internationally. In my country, anti-seepage walls are generally the preferred choice for projects such as dam foundations and cofferdams that place high demands on the cover layer's anti-seepage. Guide trough construction is a construction procedure for anti-seepage walls. It involves constructing two vertical concrete walls parallel and symmetrically to the axis of the wall, within a certain depth beyond the designed wall width. These walls serve as retaining, load-bearing, and guiding elements, and form a ground trough, also known as a guide wall or guide trough. Existing guide troughs are mostly reinforced concrete or concrete guide troughs, and are typically constructed using on-site excavation and pouring.

[0003] Regarding the relevant technologies mentioned above, it is found that the construction of anti-seepage walls is mostly carried out during the dry season, generally between December of each year and May of the following year. Since the construction period of anti-seepage walls in water conservancy and hydropower projects is relatively short, the guide wall must play its role as soon as possible. However, the existing concrete guide trough has a slow construction speed, many processes, difficult verticality control, and high construction cost, which will affect the construction progress of the anti-seepage wall.

The connecting frame 3 includes a middle frame 31 and a clamping frame 32. The clamping frame 32 is installed at both ends of the middle frame 31, and the clamping frame 32 is fixedly connected to the middle frame 31. By designing the steel guide trough into a structure in which a middle trough shell 1 and a side trough shell 2 cooperate, the middle trough shell 1 and the two side trough shells 2 can form a corresponding trough shell structure when it is easy to use. At the same time, the side trough shell 2 and the middle trough shell 1 can be connected to each other through the connecting frame 3 during installation to ensure that the two are fixed to each other. The middle trough shell 1 is spliced with a plurality of extension shells 4. In this way, the number of extension shells 4 can be selected according to the actual width of the anti-seepage wall during use, thereby adjusting the use length of the middle trough shell 1 to meet different usage requirements. By installing a reinforcement frame 5 at the outer end of the side trough shell 2, the use strength of the side trough shell 2 can be guaranteed, and the overall use stability of the steel guide trough can be increased. By designing the connecting frame 3 into a structure in which a middle frame 31 and a clamping frame 32 cooperate, the equipment at both ends can be connected together through the clamping frame 32 when it is convenient to use, and then the clamping frames 32 at both ends are fixed to each other through the middle frame 31.

By designing the clamping frame 32 into a structure in which the inner clamping plate 321, the connecting plate 322 and the outer clamping plate 323 are matched, the inner clamping plate 321 and the outer clamping plate 323 can be matched to clamp and connect when it is easy to use, and the parts on both sides can be quickly positioned and installed by the clamping frame 32, and finally locked by bolts. The head of the inner clamping plate 321 is equipped with a flip cover 324, which is rotatably connected to the inner clamping plate 321, and the two ends of the head of the outer clamping plate 323 are fixedly installed with a connecting screw sleeve 325. By installing the flip cover 324 on the head of the inner clamping plate 321, the flip cover 324 can be flipped up for easy installation. After the components on both sides are installed on the clamping frame 32, the flip cover 324 can be flipped down and fixed to each other by passing bolts through the flip cover 324 and the components and the connecting screw sleeve 325 at the lower end.
