Description

TECHNICAL FIELD

[0001] The utility model relates to the water gate engineering technical field, concretely relates to a soft base high and big water gate chamber and the separated type connecting structure of empty box bank wall. BACKGROUND

[0002] The water gate is a kind of hydraulic structure commonly seen in plain and hilly areas, and has the dual functions of water retaining and water releasing. In the water gate engineering, the bank wall is often used to connect the two banks with the gate chamber. The type of the bank wall is influenced by the height of the retaining soil, the span and the foundation of the gate chamber. When the gate chamber is high and the span is large, the reinforced concrete empty box bank wall structure is preferably used. The empty box bank wall is composed of a bottom plate, a top plate, side walls and partition walls. A bridge head protection is arranged on one side of the upper part, and traffic is arranged on the other side. The stability of the empty box bank wall is maintained by self-weight and the soil filled in the empty box or water filled in the empty box. The empty box bank wall can maintain the stability of the bank slope, reduce the adverse effect of the earth load on the gate chamber, improve the stress state of the gate chamber, increase the lateral seepage length and ensure the safety of the water gate against seepage.

[0003] The connection arrangement of the gate chamber and the empty box bank wall is mainly related to the gate foundation and the bottom plate structure of the gate chamber. There are two common types. The first type is the joint type in which the front wall of the empty box bank wall is used as the side pier of the gate chamber, and the gate chamber has a large bottom plate and a small bottom plate. The second type is the separated type in which the side pier of the gate chamber and the front wall of the empty box bank wall are separated by a deformation joint. In the joint type, the bank wall is used as the side pier, and the large bottom plate and the small bottom plate of the gate chamber are separated by a joint to reduce the adverse effect of the retaining soil on the other gate span. Although the engineering quantity is saved, the structure of the gate chamber has poor integrity, is sensitive to the deformation of the foundation, and may have uneven settlement, deformation of the gate hole, difficulty in opening and closing of the gate and other conditions. The connection form is suitable for solid foundation. In the separated type, the side pier of the gate chamber and the front wall of the empty box bank wall are separated by a deformation joint. The separated type is influenced by the large difference between the bank wall and the foundation pressure of the gate chamber, the earth load behind the bank wall and the earth pressure of the two banks. The stress state of the empty box bank wall is different at different stages. In the early stage, the empty box bank wall inclines to the river due to the earth pressure of the two banks. In the later stage, the empty box bank wall may be tilted backward due to the settlement of the foundation and the earth load. The inclination and the backward tilting of the bank wall will increase the uneven settlement of the gate chamber. Especially in the soft foundation, the settlement amount is large, and the backward tilting of the bank wall will cause the opening of the top of the deformation joint between the bank wall and the side pier of the gate chamber. The deformation joint between the bank wall and the side pier of the gate chamber is used for water stop, and the vertical water stop is prone to shear failure, and the backward tilting is prone to crack, which is dangerous to the safety of the water gate against flood.

[0053] like Figure 1 , Figure 2 As shown, the clear width B of the gate opening of the reinforced concrete grid is 2m, and the length L is 19m, which is consistent with the length of the gate chamber in the direction of water flow. This control gate is a Class I structure, and the concrete strength grade of the grid structure is C30.

[0054] like Figure 1 , Figure 2As shown, the thickness of the front wall 10, the abutment wall 11, and the side abutment wall 21 of the lock chamber is 1m. The width B1 of the abutment wall 11, the front toe wall 12, and the top cantilever slab 13 of the abutment wall is 0.99m.

[0059] Thus, in this embodiment, the 2m-wide gap between the gate chamber 02 and the empty box wall 01 is addressed by a closed reinforced concrete grid box structure for separate connection. This arrangement accommodates the differences in settlement and deformation between the gate chamber 02 and the empty box wall 01, ensuring the effectiveness of the seepage prevention arrangement between the structures and facilitating the seepage prevention safety of the sluice gate. The reinforced concrete grid bottom plate (front toe 12 of the wall) is used to adjust the stress at the base of the wall, reducing the uneven settlement between the wall and the gate chamber. The water filling in the reinforced concrete grid and the empty box offsets part of the horizontal force behind the wall, weakens the adverse effects of the side load on the wall, enhances the anti-sliding stability of the wall, and effectively controls the risk of large forward or backward tilting displacement of the wall on soft foundations.

[0060] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0061] 1. In this embodiment of the utility model, the gate chamber 02 and the empty box wall 01 are separated to form a closed box-shaped reinforced concrete grid with a permanent joint in the middle. The net width of the grid is 1.5m to 2.0m, with half of the width divided by a joint. The reinforced concrete grid bottom plate (front toe 12 of the wall) is used to adjust the stress of the wall base, reduce the uneven settlement between the wall and the gate chamber, effectively control the risk of excessive forward or backward tilting of the wall when the gate chamber 02 and the empty box wall 01 are connected separately on a soft foundation, with high retaining walls and large spans, and adapt to the differences in settlement and deformation between the gate 02 and the empty box wall 01. This solves the problem of the potential for shearing or cracking of the water stop that endangers the seepage prevention safety of the sluice gate.

[0062] 2. In this embodiment of the utility model, by using reinforced concrete grid cells and filling the empty boxes with water, the horizontal force behind the empty box abutment wall 01 can be balanced, the adverse effects of the load behind the wall on the abutment wall can be improved, the uneven settlement of the gate chamber 02 and the empty box abutment wall 01 can be reduced, and the safety and stability of the abutment wall can be increased.
