Design the leader
The sluice is irriated and arranged one of the main buildings among the project,it is a kind of low flood peak water conservancy project builing utilizing the gate to block water or sluice, can control the adjustable water level of the flow. While closing the gate, it can block the big conservation storage, the tide of the shelf or improving the water level in front of the floodgate, can release floodwater, drain flooded fields or supple water of the downstream river or the channel while opening the gate. We design the check gate built on plain and river mainly this time.
The check gate generally crosses over the river to build, used in dry season conservation storage, redound water level for sluice fetch water, turn on floodgate release floodwater flood period. In canal is it prop up to lie in generally among the department, lateral canal divide into water mouth low reaches slightly, use for redounding the water level of branch canal, for propping up, the lateral canal fetch water
This design is divided into six following parts mainly:
1.It is analysed that the materials and sluice pivot are fixed up. The materials that have already been offered are basic bases designed, in order to edable designing the achievement safe, suitable, economy, should be familiar with and analyse various kinds of materials at first, for instance topographical, geological situation, each about high Cheng, characteristic water level and corresponding flow, ect, then according to floodgate location, topography, geology, rivers, etc, terms and every building of function, characteristic, use demanding to confirm the pivot is decorateds of the pivot this, accomplish the structure compactness, rational, coordinates, beautiful.
2.Water conservancy is calculated:
Including floodgate hole design, is it can is it wash the design, prevention of seepage drain off water and design to defend to disappear mainly.
⑴The hole is designed in the floodgate give design flow definitely confirm according to sluice form and materials that draft above floodgate

毕业（论文）
hole clear width and suitable floodgate hole count at first, then checking computations plan floodgate hole size pass flow satisfied with the requirement of releasing floodwater for the first time.
⑵Disappear and can defend and print designing for dispel water flow through energy of floodgate,is it disappear strength pool, sea overflow and defend and wash the trough to design.
①Disappear in the strength pool calculate in design water storage level under the terms, gate turn on in various kinds of form, operating mode of operation and hole of floodgate, one pair of holes is turned on symmetrically, three holes open and different flow of letting out while opening the height at the same time,confirm whether to need to set up and subdueing the strength pool or not. If is it design to need, want according to condition of can disappearing,is it disappear depth, strength of pool to calculate, thickness of the length baseplate and construction material used.
②The sea overflowing disappear strength pool can dispel rivers 50% energy,other energy all over the place to dispel from sea,according to different letting out amount of the sluice,confirm long degree and construction material of sea.
③ Defend and wash the trough calculate sea overflow end wash hole depth, is it wash trough section form and size to defend to design.
⑶The prevention of seepage drains off water and designs: Draft the underground outline line at first, confirm the length tentatively, then confirm the floodgate room baseplate, length of the bedding and material sequentially, design and strain layer and drain off water in the hole position instead, calculate the base osmotic pressure of the floodgate finally, draw the distribution map of the osmotic pressure.
3.The floodgate room is decorated and floodgate room stability is calculated:
⑴Confirm the size of the outline line of floodgate room confirmed the floodgate room is always wide by the water conservancy condition, floodgate high Cheng, floodgate mound, gate, pattern, size and floodgate room top structure job bridge, traffic bridge, open and close pattern and

size of the equipment of baseplate very.
⑵The floodgate room is calculated steadily choosing the unit of calculating, build one according to finishing, normal conservation storage one, normal conservation storage issue add special to is it make up three opeerating mode checking computations floodgate room resist slippery stability and ground bear the weight of strength checking computations to load, distribute state and subside to ground stress difference carry on computational analysis, judge sluice ground meet strength of bearing the weight of, is it slip steady and out of shape requirement to resist.
⑶The deep layer of floodgate room is slipped and the subsiding amount of ground is calculated according to design soil physics characteristic index that materials provide, checking computations foundation is it drive some ground soil slip to the low reaches to happen under loading function, confirm whether to carry on the subsiding amount of the ground to calculate or not.
4.Tow sides join building-bank,structure pattern, wing of wall, assign and the stability is calculated:
⑴By physical dimension and ground terms, floodgate of room, confirm bank, level, wing of wall assign the pattern and size of section.
⑵Building an two kinks of operating modes of one and normal conservation storage according to finishing, the ground on other bank, wing wall bears the weight of strength, basis heavy minimum stress ratio count bottom surface of the base is it calculate to go on steadily to slip to resist most.
⑶Facilities of prevention of seepage in the wing wall of the upper reaches and pumping equipment on the downstream wing wall are designed.
5.The structure of floodgate room is calculated: ⑴Mound stress analysis of the floodgate:
Regard as floodgate firm to connect cantilever beam at baseplate by mound, regard the combination surfaces of the mound of the floodgate and baseplate as and calculate the chain of command, separately according to use issue (gate is it block water to shut off ) and overhaul issue two kinds of operating modes , mound vertical direct stress of horizontal
