Description

Formula lock chamber structure is backfilled to half slope

Technical Field

The utility model relates to a water route shipping technology field, concretely relates to formula lock chamber structure is backfilled to half slope.

Background

Hydropower is a clean energy, along with the continuous development of technology, the demand for electric energy is larger and larger, more and more hydropower stations are built, due to the building of the hydropower stations, rivers are cut off by the hydropower stations to form a larger difference between an upstream water level and a downstream water level, the rivers are important shipping channels, and in order to ensure that a ship can be normally shipped after the hydropower stations are built, a lock chamber needs to be built in the hydropower stations for realizing the normal shipping of the ship between the upstream and the downstream of the hydropower stations.

The ship lock chamber consists of wing walls, a lock chamber bottom plate, a traffic bridge and the like, wherein the wing walls form a main body structure of the ship lock chamber, the shipping of ships between upstream and downstream can be realized only by filling water in the lock chamber, when the lock chamber is filled with water, the wing walls need to bear considerable water pressure, in order to ensure that the wing walls have enough bearing capacity, the wing walls need to have larger dead weight, and the wing walls are generally in a trapezoidal structure (shown in figure 1) which is small in top and large in bottom and is formed by reinforced concrete, so that a large amount of steel bars, cement and the like need to be used when the wing walls are built, and the building cost is higher. In order to effectively reduce the construction cost, a ship lock chamber structure which can meet the pressure bearing capacity and save the investment cost needs to be designed by the technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: to above-mentioned problem, provide a formula lock chamber structure is backfilled to half slope, under the prerequisite of fully guaranteeing structural strength, reduce the quantity of reinforcing bar and cement, reduce its construction investment cost.

In order to achieve the above object, the utility model adopts the following technical scheme:

a semi-slope backfill type ship lock chamber structure comprises a wing wall, a lock chamber bottom plate, a water drainage hole, a valve, a lock chamber revetment and a traffic bridge, wherein the wing wall forms a lock chamber and is used for limiting a ship; the wing wall is provided with a plurality of communicating holes for communicating the lock chamber with the lock chamber protection slope, and the lock chamber protection slope is composed of backfill and a water-resisting layer.

Further, the wing wall is of a steel frame structure or a reinforced concrete structure provided with holes.

Furthermore, the ratio of the top width to the bottom width of the wing wall is 0.9-1.

Preferably, the water barrier is made of concrete.

Preferably, the chamber floor is of a concrete structure.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model discloses an ingenious design, after lock chamber is full of water, because the intercommunicating pore has been seted up on the wing wall, the pressure that its water level caused just bears by the lock chamber bank protection, and the wing wall does not bear hydraulic effect, only play the limiting displacement to the indoor boats and ships of lock, therefore, when the construction of wing wall, can set the wing wall into thinner square wall structure, and be used for bearing hydraulic lock chamber bank protection and constitute by backfill and water barrier, produced earthwork when backfill is for excavating lock chamber groove, do not need extra earthwork cost, and the water barrier only need satisfy the function that the water proof was prevented seepage can, the water barrier also can be designed into thinner structure, required concrete is also less, great reduction materials such as reinforcing bar and cement, the effectual input cost that reduces lock chamber and build.

(2) The utility model discloses the wing wall can be for steel frame construction or set up the reinforced concrete structure in foraminiferous hole, has increased the structural style of wing wall, provides the variety that the wing wall was built, also can reduce its cost of building to a certain extent.

Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

As shown in fig. 2:

the utility model provides a half slope backfill formula lock chamber structure, shifts its original water level pressure-bearing position to other positions by the wing wall, reduces the required building material of wing wall, reduces the input construction cost of lock chamber. The specific structural composition of the lock chamber comprises a wing wall 2 which forms the lock chamber 1 and is used for limiting the ship, a lock chamber bottom plate 3 arranged below the wing wall 2, the wing wall 2 and the lock chamber bottom plate 3 can be arranged into an integrated reinforced concrete structure, the lock chamber bottom plate 3 can also be arranged into a concrete structure in a separated design mode, and the wing wall is arranged into a steel frame structure and fixed on the lock chamber bottom plate 3.

The wing wall 2 is provided with a plurality of communication holes 7, the communication holes 7 can be holes formed in a reinforced concrete structure or communication spaces of a steel frame structure, the outside of the wing wall 2 is provided with a lock chamber protection slope 5, the lock chamber protection slope 5 is composed of backfill 8 and a water-resisting layer 9, the backfill can directly adopt earthwork generated when a lock chamber groove of a ship lock is excavated, extra earthwork cost is not needed, the cost is saved, and meanwhile, a method for treating the excavated earthwork is provided, and the cost generated by earthwork hauling can be reduced; the waterproof layer only needs to meet the waterproof and seepage-proofing functions, the waterproof layer can be designed into a thinner concrete structure, due to the existence of the communication holes 7, when the lock chamber 1 is filled with water, the wing walls 2 do not bear the action of water pressure, and the water pressure is borne by the lock chamber protection slope 5, so that the wing walls can be set into a thinner square structure or a large-slope trapezoidal structure with the ratio of the top width to the bottom width of 0.9-1, the material cost required by the construction of the wing walls is greatly reduced, the investment cost in the construction of the lock chamber of the ship lock can be effectively reduced, and the economic benefit of the construction of a hydropower station is improved.
