Abstract
Description
Technical Field:
[0001] The utility model relates to a low - head barrage project, specifically a thorn wall combined with a reinforced slope - attached revetment device. Background Art:
[0002] The shore project of a barrage or dam is an important part of the entire irrigation headworks project, which has an important impact on the flow - passing condition and plays an important role in the project safety. Whether it is the project cost or the construction difficulty, it occupies a relatively large proportion in the project construction. The conventional - designed shore project generally consists of the following parts: ① The side piers of the sluice chamber and the head walls of the dam; ② The upstream wing walls (including the inlet end walls); ③ The downstream wing walls (including the outlet end walls); ④ The upstream slope protection; ⑤ The downstream slope protection. The design of the shore project should ensure the stability of the riverbank, meet the water inlet and outlet flow conditions, improve the energy - dissipation and anti - scouring effects, meet the lateral seepage - around conditions, minimize the project cost, and be convenient for construction. Summary of the Invention:
[0003] The purpose of the utility model is to provide a structural layout plan for the shore project that is simple in structure, convenient for construction, saves investment, can prevent lateral seepage around the shore, and is more capable of resisting ice thrust and the frost heaving and thaw settlement of foundation soil, and can ensure the safety of the pivot.
[0004] The purpose of the utility model is realized as follows: It includes a thorn wall (1), a thorn - wall circular arc diversion section (2), a reinforced slope - attached revetment (3), a barrage (4), a water - stop belt (5), a concrete lining (6), a stone masonry with steel reinforcement cage (7), a pebble cushion layer (8), and a non - woven fabric (9). The reinforced slope - attached revetment (3) is connected to both sides of the thorn wall (1), the thorn - wall circular arc diversion section (2) is provided at the end of the thorn wall (1), the thorn - wall circular arc diversion section (2) is connected to the barrage (4), a water - stop belt (5) is provided at the connection of the thorn - wall circular arc diversion section (2) and the barrage (4), the stone masonry with steel reinforcement cage (7) is provided under the concrete lining (6), the pebble cushion layer (8) is provided under the stone masonry with steel reinforcement cage (7), the non - woven fabric (9) is provided under the pebble cushion layer (8). The height of the concrete lining (6) is a, a = 15 cm, the height of the stone masonry with steel reinforcement cage (7) is b, b = 35 cm - 85 cm, and the height of the pebble cushion layer (8) is c, c = 10 cm.
[0005] The advantages of the utility model are: simple in structure, convenient for construction, low in cost, and can prevent lateral seepage around the shore, resist ice thrust and the frost heaving and thaw settlement of foundation soil. Brief Description of the Drawings:
