Background technology
In the design in navigation structure, reasonably determine the arrangement and the correct guide work thing structural shape of selecting of approach channel, avoiding occurring bad fluidised form in the approach channel, make the steady lockage of fleet's (oceangoing ship) and berth, is an important technology index weighing the ship lock safe operation.
To the approach channel layout requirement, China has accumulated abundant design experiences in the Changjiang river and inland river ship lock engineering construction, ripe operational management experience is also arranged according to " ship lock design specifications ".But for the large-scale ship lock in the mountain stream key water control project, the layout of approach channel and related knowledge question of water conservancy, go back imperfection in theory, need to study the layout of guide wall and the hydraulics in Kou Men district by hydraulic model test, thereby check is under the power station release floodwatering flow influences, the service condition of fleet's (oceangoing ship) in approach channel and the velocity flow pattern in Kou Men district.Also have the excessive problem of channel downstream Kou Men district backflow simultaneously, some guide work thing riverbed of living in covering layer is deep, huge, the constructional difficulties of structure.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of water conservancy diversion navigation pier structure is provided, is intended to solve door district, pilotage road junction, navigation structure and refluxes excessive and technical problem such as the construction period in dry season is too short.
The technical scheme that the utility model adopted is: water conservancy diversion navigation pier, this water conservancy diversion navigation pier has several, the Parallel to the flow direction setting also makes the riverbed be divided into moving aqua region and hydrostatic zone, it is characterized in that: described water conservancy diversion navigation pier is overlooked direction and is trapezoidal, its right-angle side is towards the hydrostatic zone of navigation channel side, and water conservancy diversion navigation pier connects into an overall structure by the ladder type panel wall structure on top, the concrete pipe base wall construction and the middle concrete apron that plays the transition interconnect function of bottom.
Described ladder type panel wall is that cross section is trapezoidal whole reinforced concrete box structure, the inner rock ballast of filling of panel wall, and panel wall top envelope has cover plate, and the panel wall sidewall is provided with gutter.
Described concrete pile foundation wall is that the ascending steel concrete board wall of a group length constitutes, and the lower end of board wall stretches to basement rock and utilizes below the line.
Described concrete apron is a cap-like structure, and upper plane and ladder type panel wall are fixed, and the bottom apron is enclosed within concrete pile foundation wall outside and is connected by reinforcing bar.
To the original place upper thread that end in water conservancy diversion navigation pier cushion cap sideline, the shop cover concrete grid block at all moving aqua region.
Link by shackle between described each concrete grid block.
The beneficial effects of the utility model are: the utility model basis " ship lock standard " is to the velocity flow pattern requirement of door district, pilotage road junction, adopt ladder type panel wall and concrete pipe base wall composite construction, top navigation pier adopts ladder type panel wall type body to play the conductance stream effect of choosing, reduce the transverse flow speed in Kou Men district, improved the navigation condition of approach channel turnover boats and ships; Bottom basis adopts the pile foundation wall construction to carry out subaqueous construction in dry season, need not build the interim cofferdam top sash wall construction of directly constructing, and has shortened the duration, has saved investment, has satisfied instructions for use.Be difficult to satisfy design challenges such as code requirement to solving door district, pilotage road junction, mountain stream navigation structure, the utility model benefit is obvious.

The specific embodiment
As shown in Figure 1, present embodiment water conservancy diversion navigation pier has 3, and the Parallel to the flow direction setting also is divided into moving aqua region I and hydrostatic zone II with the riverbed, and described water conservancy diversion navigation pier is overlooked direction and is trapezoidal, upstream side is little and the downstream is big, the hydrostatic zone II of right-angle side one side towards the navigation channel of water conservancy diversion navigation pier.Water conservancy diversion navigation pier connects into an overall structure by ladder type panel wall 1 structure on top, concrete pile foundation wall 3 structures and the middle concrete apron 2 that plays the transition interconnect function of bottom.The ladder type panel wall body on top has the effect of the conductance of choosing stream, and can alleviate the deadweight of pier body top.
As shown in Figure 4, described ladder type panel wall 1 is trapezoidal whole reinforced concrete box structure for cross section, adopts rock ballast 1b backfill in the middle sash, the panel wall top adopts concrete cover 1c to bind, the panel wall sidewall is provided with gutter 1a, and its diameter D is 6cm, with hydraulic pressure inside and outside the balance.
As Fig. 2, Fig. 3, shown in Figure 5, described concrete pile foundation wall 3 is that the ascending steel concrete board wall of a group length constitutes, and is increased to the D wall as length gradually from the A wall, and the lower end of board wall stretches to basement rock and utilizes line below 6.
As Fig. 2, shown in Figure 3, described concrete apron 2 is a cap-like structure, and upper plane and ladder type panel wall 1 are fixed, and the bottom apron is enclosed within concrete pile foundation wall 3 outsides and is connected by reinforcing bar.Concrete apron 2 can be used as the operation platform of top ladder type panel wall 1 during construction, plays the effect of forming a connecting link.
