Embodiment 1

[0043] Such as figure 1As shown, a vertical water-stop structure of a water conservancy project includes a dam body 1. The top wall of the dam body 1 is provided with installation grooves 11 along the vertical direction. At least two groups of installation grooves 11 are provided. . Each group includes a plurality of installation grooves 11 distributed at intervals along the length direction of the dam body 1 , and the installation grooves 11 of two adjacent groups are staggered. Each group of installation grooves 11 is collinear along the length direction of the dam body 1, and the distance between each group of adjacent two installation grooves 11 is less than the length of the installation grooves 11, and a waterproof compact layer 7 is arranged between two groups of adjacent installation grooves 11 , the waterproof dense layer 7 is connected with the end of the installation groove 11 to prevent water from leaking from the interval between the two installation grooves 11; ...

Embodiment 2

[0057] A vertical water stop construction method for water conservancy projects, comprising the following steps:

[0058] S1. Excavate the foundation pit, excavate the foundation pit on both sides of the roadbed facing the river according to the designed width, and lay waterproof piles around the foundation pit;

[0059] S2. Formwork production. According to the design, the dam body formwork and the installation groove formwork are produced;

[0060] S3. Formwork installation, install and fix the dam body formwork in the foundation pit, and then fix the installation groove formwork between the dam body formwork, set up two groups of installation groove formwork, each group is arranged at intervals along the length direction of the dam body 1, and the two The dislocation setting of the installation groove template of the group;

[0061] S4, pouring the dam body 1, pouring concrete in the formwork of the dam body 1;

[0062] S5, formwork removal, after the concrete is solidifi...

Abstract

The invention relates to a vertical water-stop structure of a water conservancy project and a construction method thereof, belonging to the technical field of water conservancy engineering, comprising a dam body, the top wall of the dam body is provided with installation grooves along the vertical direction, at least two groups of installation grooves are arranged, and each group is It includes a plurality of installation grooves distributed at intervals along the length direction of the dam body. The installation grooves of two adjacent groups are misplaced, and waterproof components are detachably installed in the installation grooves; A drainage pipe communicating with the installation groove is pierced inside the cover plate, and an end of the drainage pipe protruding out of the installation groove is connected with a visible pipe. If the waterproof component is damaged, the water in the river will seep into the installation groove. Because the installation groove is in a closed state, under the water pressure, the water in the installation groove will enter the visible pipe through the drain pipe; Replacement and maintenance of the waterproof components corresponding to the visible pipes; no need to repair the waterproof components of the entire dam body; simple maintenance and reduced maintenance costs.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a vertical water stop structure of a water conservancy project and a construction method thereof. Background technique [0002] At present, some vertical concrete structures are used on both sides of the river in some parks and scenic spots to retain water; at the same time, it can also reduce soil loss. [0003] The Chinese patent with the authorized notification number CN204385682U discloses a water conservancy project dam anti-seepage and water-stop structure, which includes a dam body, the dam body is provided with an anti-seepage slope, the surface of the anti-seepage slope is provided with an anti-corrosion layer, and the lower part of the anti-corrosion layer is provided with a concrete fixing The lower part of the concrete fixed layer is provided with a waterproof membrane layer, the lower end of the dam body is provided with a first anti-seepage bod...
