Abstract
The invention relates to a reverse-inclined double-layer water inlet structure. The invention is designed to provide a reverse-inclined double-layer water inlet structure in order to solve design difficulties in selection of water inlets in a high-head lock filling-emptying system, simplification of the structure arrangement and satisfaction of hydraulic conditions etc. The technical scheme in the invention comprises the arrangement as follows: a reverse-inclined double-layer water inlet structure has concrete sluice piers on both left and right sides and a concrete water-stop plate between the concrete sluice piers on both left and right sides. The reverse-inclined double-layer water inlet structure is characterized in that upper-layer and lower-layer water inlets are set on an upstream face of the concrete water-stop plate. The water inlets are communicated to water delivery galleries on the bottoms of the sluice piers via inflowing galleries and vertical S-type turning sections buried in the concrete sluice piers; the upstream face of the inflowing section of the concrete water-stop plate is reverse-inclined with a reverse angle alpha of not more than 45 DEG. The structure is applicable to water conservancy and hydropower projects and waterway transportation projects.
Description
Technical field
The present invention relates to a kind of bilayer of falling inclined water inlet structure.Be applicable to Hydraulic and Hydro-Power Engineering, water transport traffic engineering.
Background technology
The development in navigation structure has the history of 2000, nearly 4000 of the built ship lock in the current whole world.The history that China's ship lock is built is very long, and built nearly 800 of ship lock, accounts for 20% of whole world ship lock sum so far.Filling-emptying system of lock water inlet position and moulder moisture whether reasonable, be one of key factor ensureing ship lock water-delivery effect.According to China's transportation industry current specifications, water-carriage system water inlet is arranged in reservoir needs certain underwater penetration and water surface area, avoid the string-like air-breathing whirlpool producing harmfulness, enter the HYDRODYNAMIC CONDITION RELATING TO of ship lock mouth door and structural configuration for principle to meet boats and ships.Therefore, moulder moisture has diversity.
In recent years, along with the enforcement of strategy to develop western regions, China's inland water transport cause obtains fast development, and a collection of large-scale ship lock puts into operation in succession.As: Changzhou, the Xijiang River three, the four line ship lock that inland water transport hinge is largest in the world, Guiping Second Line Shiplock, Changsha double lock, Jia Lingjiang River Cao Jie ship lock, draws Jiang Jihan navigation lock, Yang Jia gulf, canal, overgrown with weeds Shen ship lock.Large-scale ship lock construction, because river is different, head is different, applying mechanically type selecting according to specification can not adapt to ship lock construction requirements merely, the power station narrow for riverbed, mountain area, peak flood flow is huge, project playout is narrow, navigation structure water-carriage system water inlet is arranged, is necessary to break through routine, research and innovation achievement, arranges and service requirement to meet high-lift lock water inlet.
Summary of the invention
The technical problem to be solved in the present invention is: for above-mentioned Problems existing, provides a kind of bilayer of falling inclined water inlet structure, to solve high-lift lock water-carriage system water inlet type selecting, simplify structural configuration, to meet the design challenges such as HYDRODYNAMIC CONDITION RELATING TO.
The technical solution adopted in the present invention is: a kind of bilayer of falling inclined water inlet structure, there is left and right sides concrete pier, and the concrete water-stop sheet between the concrete pier of both sides, it is characterized in that: the upstream face of described concrete water-stop sheet is provided with upper and lower two-layer water inlet, water inlet is through being embedded in the culvert bottom the inlet passage in concrete pier, three-dimensional S turn section connection gate pier; The upstream face of described concrete water-stop sheet water inlet section is in falling inclined, chamfering α≤45 °.
Be provided with perpendicular to water inlet and block dirty coral groove, this blocks in dirty coral groove and lays trashrack.
Described water inlet base plate is that circular arc β=90 ° are arranged in import department.
Described S turn section is formed by connecting by two facade γ=60 ° turnings.
The invention has the beneficial effects as follows: the present invention is by water inlet centralized arrangement in limited structural sections, and letter has been lacked lock head structure hole, simplified gate pier layout, optimizes lock head stress, reduces difficulty of construction, accelerate construction speed, save construction investment; Through hydraulic model test checking, the water inlet depth of water meets the demands, in storehouse without harmfulness rotary roll, bubble generation, flow-shape well, smooth and easy, uniform fluid flow of intaking.

Detailed description of the invention
As shown in Fig. 1 ~ Fig. 3, the present embodiment is a kind of bilayer of falling inclined water inlet structure, utilizes the concrete water-stop sheet 2 of ship lock water inlet structure section and concrete pier 1 space of water-stop sheet both sides to arrange the levels of falling inclined water inlet 6, inlet passage 3, S turn section 4, culvert 5 and trashrack groove 7.In this example, upper and lower two-layer water inlet 6 is set at concrete water-stop sheet 2 upstream face, its at the middle and upper levels water inlet by being embedded in inlet passage 3 in the concrete pier 1 on right side, composition S shape passage is turned in S turn section 4(two facade γ=60 °) be connected culvert 5 bottom the concrete pier 1 of right side; Lower floor's water inlet by being embedded in inlet passage 3 in the concrete pier 1 in left side, composition S shape passage is turned in S turn section 4(two facade γ=60 °) be connected culvert 5 bottom the concrete pier 1 of left side, water body enters the S turn section 4 of water-carriage system by water inlet 6, inlet passage 3, then enters in culvert 5.
The upstream face in the present embodiment, concrete water-stop sheet 2 being arranged water inlet section, in falling inclined, ° to be arranged in chamfering α=45, enters hydrospace, reduce import flow rate of water flow with what increase import water body.Water inlet 6 base plate is that circular arc β=90 ° are arranged in import department, enters and smooth water flow's fluidised form to accelerate current.
In concrete water-stop sheet 2, water inlet position arranges the trashrack groove 7 of vertical inlet mouth 6 and lays trashrack, enters in culvert with dirt in storehouse, upstream of blocking.
The concrete construction method of the present embodiment is as follows:
Carry out water inlet gate pier architecture basics and excavate → build a left side, right concrete pier 1 → formwork erection builds a left side, culvert 5 in right gate pier, S turn section 4 periphery concrete → formwork erection is constructed left gate pier inlet passage 3, build the periphery concrete → formwork erection construction lower floor of falling inclined water inlet 6 → reserved trashrack groove 7 bottom notch → formwork erection concreting water-stop sheet 2 bottom concrete → formwork erection to construct right gate pier inlet passage 3 → formwork erection construction upper strata of falling inclined water inlet 6 → reserve in the middle part of trashrack groove 7, in the middle part of upper notch → formwork erection concreting water-stop sheet 2, top concrete → build a left side, right concrete pier 1 top concrete, until gate pier top.
