Abstract
The invention discloses a structure for improving a water and sand condition of a lock gate recess. The structure comprises a gate recess, a gate chamber and a gate; the tail end of a gate chamber water outlet branch gallery of the gate recess is provided with an auxiliary water outlet gallery which is U-shaped or rectangular; the minimum submergence depth on the top of the gallery is not smaller than the water depth of a lock threshold; and the side wall of the auxiliary water outlet gallery is provided with a plurality of water inlet holes. The adopted auxiliary water outlet gallery has a simple structure, is convenient to construct and maintain, and can greatly reduce the operation and maintenance cost of a lock when the operation safety of the lock is guaranteed.
Description
Technical field
The present invention relates to a kind of engineering structures that can improve rocky navigable river lock gate door storehouse flow condition and sedimentation situation, a kind of specifically structure of improving the husky condition of lock gate door storehouse water.
Background technology
Ship lock is a kind of navigation structure that overcomes the concentrated water-head of building dam (or natural) formation on the river, and it is made up of last tail-bay, gate, lock chamber etc.Gate be in the lock chamber water delivery process in order to the sealing lock chamber, water delivery finish to finish boats and ships turnover lock key equipment, a door storehouse then is the space that is used to hold gate opening/closing.
Because the restriction of lock chamber structure, gate Men Kunei can't arrange the water delivery gallery that contains weep hole, so Men Ku belongs to the non-outlet area in the lock chamber.And fill at lock chamber, in the sluicing process, the current that the outlet area enters in the lock chamber in the lock chamber will flow to Men Kunei, and reflect at gate, thereby produce significantly vertically current and back and forth fluctuation at gate Men Kunei, and can produce bad hydraulic phenomenon such as separated flow, rotary water current in sudden change place of door library partition, cause the flow-shape of gate Men Kunei very complicated, this will directly have influence on the security of operation of gate.
In addition, great majority are heavily silt-carrying river in the navigable river of China, in view of the operating experience of three ship lock in Ge Zhou Ba, influence the lock gate operation except that knowledge question of water conservancy, also have gate door storehouse sedimentation problem.The maximum sedimentation thickness in No. 1 lock gate door storehouse, Ge Zhou Ba reaches about 3m, and sedimentation makes miter gate have to open and close in very thick mud, has enlarged markedly the moment of resistance the when miter gate opens and closes, and has aggravated Bottom Hinge for Miter lock Gate and sealing abrasion degree.
Thereby, how to improve the flow condition and the sedimentation problem in lock gate door storehouse, become the problem that construction, design and scientific research personnel pay special attention to, and rarely had successful case can supply to use for reference both at home and abroad in this regard.
Summary of the invention
Technical problem to be solved by this invention is: have shortcoming at above prior art, propose a kind of husky condition of water that can either improve lock gate Men Kunei, can reduce difficulty of construction again simultaneously, construction investment is saved in convenient maintenance, reduces the structure of running cost.
The technical scheme that the present invention solves above technical problem is: the present invention improves a kind of structure of improving the husky condition of lock gate door storehouse water, comprise gate door storehouse, lock chamber and gate, prop up the gallery end in the lock chamber water outlet in described gate door storehouse and be provided with auxiliary water outlet gallery, described auxiliary water outlet gallery takes the shape of the letter U or rectangle; The minimum depth of the water submerging at described auxiliary water outlet gallery top is not less than the ship lock water depth on sill; Described auxiliary water outlet gallery sidewall is provided with some weep holes; Utilize auxiliary water outlet gallery to reach the purpose of disperseing current and sand surfing.
The technical scheme that the present invention further limits is: the aforesaid structure of improving the husky condition of lock gate door storehouse water, described auxiliary water outlet corridor width should cover the width of assisting the water outlet corridor to whole door base area under the situation that structure allows as much as possible smaller or equal to described gate door storehouse width.
The aforesaid structure of improving the husky condition of lock gate door storehouse water, described weep hole is square, the area of single weep hole be no more than original lock chamber single weep hole area 1/20, the weep hole gross area on the described auxiliary water outlet gallery is 1～1.35 times of original single lock chamber weep hole area, and the terminal level pressure difference of gallery head and the tail satisfies greater than 1mH when branch
2During O; What guaranteed weep hole goes out the initial velocity of flow velocity greater than silt, has reached the purpose that prevents sedimentation.
Further, the aforesaid structure of improving the husky condition of lock gate door storehouse water is provided with the power beam that disappears between the weep hole outside of described auxiliary water outlet gallery and the lock wall.
Advantage of the present invention is: (1) is propped up the gallery end in the lock chamber water outlet in close lock gate door storehouse and is added U-shaped or the auxiliary water outlet gallery of rectangle, has reduced the non-outlet area of gate Men Kunei significantly, has improved the flow condition in the ship lock gate storehouse effectively; (2) at the terminal surplus pressure of branch gallery head and the tail greater than 1mH
2Under the prerequisite of O, and the ostium excurrens of set some, guaranteed that weep hole goes out the initial velocity of flow velocity greater than silt, has reached the purpose that prevents sedimentation; (3) energy-dissipating installation such as the power beam that disappears is set between auxiliary water outlet gallery and lock wall, has reduced the turbulent fluctuation that auxiliary water outlet gallery goes out stream, further improved the flow condition of gate Men Kunei; (4) auxiliary water outlet gallery is simple in structure, and construction when guaranteeing the lock gate security of operation, also can reduce the operation expense of ship lock with easy to maintenance greatly.
Flow condition and the sedimentation problem in the lock chamber of gate Men Kunei are the focuses that scientific research and designer are paid close attention to always in filling-emptying system of lock design, the present invention has improved the flow condition of gate Men Kunei effectively, also can prevent the Men Kunei sedimentation simultaneously, and simple in structure, easy construction, significantly save operation and maintenance cost, had good application prospects.

The specific embodiment
Embodiment 1
Present embodiment is a kind of structure of improving the husky condition of lock gate door storehouse water, structure as depicted in figs. 1 and 2, comprise gate door storehouse 1, lock chamber and gate 2, prop up gallery 3 ends in the lock chamber water outlet in gate door storehouse and be provided with auxiliary water outlet gallery 4 that auxiliary water outlet gallery takes the shape of the letter U or rectangle; The minimum depth of the water submerging at auxiliary water outlet gallery top is not less than the ship lock water depth on sill; Auxiliary water outlet gallery sidewall is provided with some water outlet square holes 5; Utilize auxiliary water outlet gallery to reach the purpose of disperseing current and sand surfing; Auxiliary water outlet corridor width should cover the width of assisting the water outlet corridor to whole door base area under the situation that structure allows as much as possible smaller or equal to gate door storehouse width; The terminal level pressure difference of gallery head and the tail satisfies greater than 1mH when branch
2During O; What guaranteed weep hole goes out the initial velocity of flow velocity greater than silt, has reached the purpose that prevents sedimentation, is being provided with the power beam that disappears between the weep hole outside of auxiliary water outlet gallery and lock wall.
