Abstract
The utility model relates to an intercepting ditch structure for a steeper terrain, and belongs to the technical field of water conservancy and hydropower engineering application. The intercepting ditch structure comprises an intercepting ditch and falling sills, wherein the falling sills are integrally connected with the inner wall of a sidewall of the intercepting ditch and the top surface of a bottom plate. According to the intercepting ditch structure, the falling sills are arranged in the intercepting ditch, so that the energy of water flow in the intercepting ditch can be effectively dissipated, the flow velocity of the water flow can be reduced, requirements on a material for the intercepting ditch can be lowered, the arrangement of an energy dissipation sour protection facility at an outlet can be avoided, and the investment is reduced; in addition, the length of the intercepting ditch can be reduced from arrangement, so that the investment is also reduced; the intercepting ditch structure is simple in structure, economical and feasible, and has broad application prospect.
Description
Technical field
The utility model relates to a kind of catchwater structure for steeper landform, belongs to Hydraulic and Hydro-Power Engineering applied technical field.
Background technology
In Hydraulic and Hydro-Power Engineering, conventionally need in the steeper side slope of landform, catchwater be set, steeper because of the gradient, while arranging catchwater, general low-angle is crossing with isohypse, makes catchwater longitudinal gradient relatively mild, but catchwater length can increase much like this, increase of investment; Or be arranged vertically with isohypse, in catchwater, flow rate of water flow is larger like this, and catchwater impact-resisting wear-resisting is had relatively high expectations, due to high-velocity flow washing away catchwater inwall, can cause catchwater structural damage, generally adopt high grade impact-resisting wear-resisting concrete, can make like this increase of investment; Catchwater outlet generally need to arrange energy dissipating erosion control facility in addition, has increased again investment.
Utility model content
For above technological deficiency, the purpose of this utility model is to provide a kind of catchwater structure for steeper landform little, simple in structure of investing.
To achieve these goals, the utility model is by the following technical solutions:
For a catchwater structure for steeper landform, comprise catchwater and fall bank, described in fall bank and be connected with catchwater side wall inwall and plate top surface and form overall.
Described catchwater is stone masonry structure with falling bank, and its upstream face is smeared cement mortar as impervious barrier.
Described catchwater is concrete structure with falling bank.
The described catchwater cross-section of river is shaped as trapezoidal or rectangle.
The described bank section configuration of falling is rectangle or trapezoidal.
The described bank that falls is perpendicular to water (flow) direction.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, by the structure of falling bank is set in catchwater, can effectively carry out energy dissipating to the current in catchwater, reduces flow rate of water flow, reduces the requirement of catchwater material, can avoid, in outlet, energy dissipating erosion control facility is set, and has reduced investment; Can be set up and reduce catchwater length from cloth in addition, also reduce investment; It is simple in structure, and economically feasible has and has broad application prospects.
Brief description of the drawings
Fig. 1 is drawing in side sectional elevation of the present utility model;
Fig. 2 is longitudinal plan of the present utility model.
In figure: catchwater 1, fall bank 2.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but claimed scope is not limited to content described in the present embodiment.
As shown in Fig. 1～Fig. 2, the utility model is a kind of catchwater structure for steeper landform, comprise catchwater 1 and fall bank 2, described in fall bank 2 and be connected with catchwater 1 side wall inwall and plate top surface and form overall.
Described catchwater 1 is stone masonry structure with falling bank 2, and its upstream face is smeared cement mortar as impervious barrier.Stone masonry structure can be gathered materials on the spot, and saves investment.
Described catchwater 1 is concrete structure with falling bank 2.Concrete structural strength is high, and erosion resistibility is relatively strong.
Described catchwater 1 cross-section of river is shaped as trapezoidal or rectangle.Trapezoidal cross-section is better to soil property, rock matter basis compliance; Rectangular cross section floor space, invest little; Both sides height of side wall is definite according to both sides landform, and general 20～30cm above ground level is advisable; Trapezoidal cross-section two side slope ratios are generally 1:0.3～1:0.5, and bottom width is generally 0.5～2m; Rectangular cross section bottom width is generally 0.5～2m; Stone masonry structure side wall and base plate thickness are generally 0.3m～0.5m; Concrete structure side wall and base plate thickness are generally 0.1m～0.3m.
The described bank 2 that falls is perpendicular to water (flow) direction, to reach better effect of energy dissipation.
Described bank 2 section configurations of falling are consistent with place catchwater 1 cross-section of river shape, are rectangle or trapezoidal; Highly generally higher than catchwater 1 base plate 0.2～1m, and lower than height of side wall 0.3～1m; When its Transverse to the flow direction is stone masonry structure its thickness be generally 0.3m～0.5m, the general 0.1m～0.3m of its thickness when the concrete structure.
The utility model, in the time of construction, mainly carries out in accordance with the following steps:
The first step, first determines catchwater 1 and the physical dimension of falling bank 2;
Second step, determines the axial location of catchwater 1, carries out unwrapping wire, excavation;
The 3rd step, builds catchwater 1 by laying bricks or stones and falls bank 2, requires catchwater 1 and falls bank 2 and build simultaneously and form entirety by laying bricks or stones.
