Description

Technical Field

[0001] The utility model relates to the technical field of plain sluice shaft, in particular to a plain sluice shaft device. Background Technique

[0002] A sluice is a low-head hydraulic structure with the dual functions of water retaining and water discharging, and is widely used in water conservancy projects. Its main functions include not only controlling the flow rate and regulating the water level by opening and closing the gate, but also preventing the backflow of tides and discharging floodwaters during the flood season. In the overall structural design of the sluice, the elevation of the sluice top needs to be designed first. This sluice elevation usually refers to the elevation of the upstream pier and the top of the bank wall at the breast wall of the sluice chamber or the water retaining line of the gate. Since the sluice is a hydraulic structure with both water retaining and water discharging functions, the elevation of the sluice top should be determined according to the water retaining and water discharging operation conditions. When retaining water, the elevation of the sluice top should not be lower than the sum of the normal storage water level or the highest water retaining level of the sluice plus the calculated wave height and the corresponding safety heightening value; when discharging water, the elevation of the sluice top should not be lower than the sum of the design flood level or the checking flood level and the corresponding safety heightening. For sluices located on flood control and tide embankments, the elevation of the sluice top should not be lower than the elevation of the top of the flood control and tide embankments. In addition, when determining the elevation of the sluice top, the influence of the settlement of the sluice foundation on soft ground, the possible rise of the water level after sediment deposition in front of the sluice on sediment-laden rivers, and the possible heightening of the top of the embankments on both sides of the sluice on flood control and tide embankments should also be considered respectively.

[0003] Currently, in the plain area, for the through-dike sluices such as the intake sluice and drainage sluice that cross the flood control dike, in the conventional design, for the convenience of operation, maintenance and overhaul, the newly built (or rebuilt) sluice positions are usually arranged on the half-slope between the top and the bottom of the dike. The dike body often adopts the culvert sluice type, and a straight retaining wall or a flared retaining wall is set at the inlet / outlet of the through-dike culvert sluice to connect with the upstream and downstream dike slopes and the river respectively. The foundation treatment often adopts cast-in-place piles and other methods. See the appendix Figures 1 to 3 As shown, it is integrally composed of a sluice chamber section and an inlet retaining wall section connected. The sluice chamber section has an open sluice chamber 110, including a gate panel 111. The downstream of the sluice chamber section ( Figure 1The culvert passing through the dike (on the left side in the middle) is a culvert passing through the dike. The gate chamber section is supported by multiple reinforced concrete cast-in-place piles 113 at the bottom. The inlet retaining wall section includes a counterfort retaining wall 112. The problems of this design are as follows: ① When a trash rack needs to be set at the inlet of the culvert and sluice and the conditions for closing the sluice for maintenance at different water levels need to be met simultaneously, the layout of the gate chamber is complex and the size is large, resulting in a large investment in the civil engineering of the culvert and sluice. ② The stability calculation results of the culvert passing through the dike determined according to the above design principles, such as the anti-sliding safety factor, the base stress and the non-uniformity coefficient, the foundation settlement, etc., do not meet the requirements of the specifications, and the foundation of the culvert passing through the dike needs to be treated. ③ Since the sluice position is located within the dike slope, the backfill height of the soil behind the inlet / outlet retaining walls of the culvert passing through the dike is generally large, resulting in large structural sizes of the inlet / outlet retaining walls and the stability calculation results of the high retaining walls generally not meeting the requirements of the specifications. The foundation of the high retaining walls needs to be treated with pile foundations, which causes a large increase in project investment. Utility Model Content

[0022] The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The plain sluice well device of the embodiment of the present application is mainly used to solve the problems in the conventional layout and structural design of the culvert sluice through the dike in the prior art. In the conventional layout and structural design, the determined sluice chamber layout is complex and has a large size, and the height and size of the inlet / outlet retaining wall are relatively high, resulting in that the structural stability calculation results of the culvert sluice chamber, retaining wall, etc. do not meet the specification requirements and pile foundation treatment is required, causing a large amount of civil engineering work and a large increase in project investment.

[0024] Please refer to Figures 4 to 5 As shown in the figure, in the embodiment of the present application, the plain sluice well device includes a sluice well and a multi-hole inlet / outlet box culvert 13 connected to the sluice well. The inlet / outlet box culvert is connected to the culvert box through the flood control dike 26. The sluice well includes multiple gates 10 and high water level maintenance gate slots 11. Each gate 10 corresponds to one hole of the inlet / outlet box culvert 13. A low water level maintenance gate slot and trash rack slot 16 is arranged on the water inlet side of the inlet / outlet box culvert, and a high water level maintenance gate slot 11 is arranged in the sluice well.

[0025] Among them, retaining walls are arranged on both sides of the inlet / outlet box culvert, and the retaining walls are located on the water inlet side or the water outlet side of the inlet / outlet box culvert. Specifically, the retaining wall includes a first retaining wall 21 and a second retaining wall 22. The second retaining wall 22 is outside the first retaining wall 21, and the first retaining wall is connected to the inlet / outlet box culvert.

[0026] In some embodiments, a mortar rubble slope protection 23 of the sluice well is arranged between the retaining wall and the flood control dike. The mortar rubble slope protection 23 of the sluice well is arranged on both sides of the inlet / outlet box culvert. The mortar rubble slope protection 23 of the sluice well is an inclined slope, which is an inclined slope with a higher left side and a lower right side in the figure. The lower end is connected to the retaining wall, and the upper end is connected to the flood control dike 26.

[0027] In the preferred embodiment, the retaining wall and the rubble slope protection are symmetrically arranged with the center line of the sluice well as the axis.

[0028] In some embodiments, the mortar rubble slope protection of the sluice well has a base slope formed by backfill soil. The surface of the base slope is sequentially provided with a geotextile, a gravel cushion layer, and an outer layer structure 19 formed by a mortar rubble layer from bottom to top, so as to form the mortar rubble slope protection 23.

[0029] In some embodiments, the two sides of the water inlet side of the inlet / outlet box culvert are symmetric mortar rubble slope protection structures 25. A mortar rubble bottom protection 24 is formed between the symmetric mortar rubble slope protections. The symmetric mortar rubble slope protections and the mortar rubble bottom protection form a water inlet structure.

[0030] In some embodiments, the bottom plate of the inlet / outlet box culvert adopts a reinforced concrete bottom plate 17, and its bottom is supported by a plain concrete cushion layer 18.

[0031] Among them, the top of the sluice well is a platform structure. There is a guardrail 14 on the outside of the platform structure, and a top cover plate 15 of the platform structure covers the upper opening of the sluice well.

[0032] In some embodiments, a ladder 12 is arranged on one side of the sluice well for maintenance personnel to go from the top of the sluice well to the bottom of the sluice well for maintenance during maintenance.

[0033] As can be seen from the description of the background technology of this application, in the conventional design of the culvert sluice crossing the flood control dike, the sluice chamber structure is usually arranged in an open style, and a straight retaining wall or a flared retaining wall is respectively set at the inlet (or outlet) of the culvert sluice to connect with the upstream and downstream channels. The sluice chamber structure and the inlet / outlet retaining wall sizes determined in this way are relatively large, and the height of the inlet / outlet retaining wall body is relatively high, resulting in that the structure often needs to adopt pile foundations for foundation treatment, and the civil engineering quantity and investment increase relatively much.

[0034] In the embodiment of this application, the specific implementation steps of the plain sluice well device are as follows:

[0035] (1) According to the number of sluice holes and the sluice hole sizes determined by hydraulic calculation, initially estimate the basic size of the sluice well, and in combination with the design conditions of the culvert sluice crossing the flood control dike (including upstream and downstream inlet / outlet elevations, slope ratios, operating water levels, dike top elevation, etc.), determine the preliminary layout scheme of the culvert sluice well device.

[0036] (2) According to the obtained geological exploration results and specification requirements, adjust the position and size of the sluice well and the inlet (or outlet) retaining wall, as well as the length and joint position of the upstream / downstream culvert box culvert passing through the dike and other condition factors, and perform stability calculation, structural calculation, settlement calculation, pile foundation calculation, etc. on the proposed sluice well device. In combination with technical and economic comparison and selection, determine the optimal layout scheme of the sluice well device.

[0037] (3) Respectively set high-water-level and low-water-level maintenance gate slots (which can also be used as trash rack slots) in the sluice well C and at the inlet (or outlet) of the culvert box culvert passing through the dike to meet the maintenance requirements under different water level conditions.

[0038] In contrast, the plain sluice well device of the embodiment of this application has the following advantages:

[0039] (1) By improving the layout method of the culvert sluice crossing the dike, under the functional conditions of meeting the operation and maintenance of the culvert sluice crossing the dike and the maintenance requirements under different water level conditions, the structural stress conditions of the conventional culvert sluice crossing the dike can be effectively improved, the height of the inlet / outlet retaining wall body can be reduced, the pile foundation treatment measures for the culvert sluice crossing the dike and the retaining wall can be optimized, and the civil engineering quantity and project investment can be reduced.

[0040] (2) By adjusting the number of sluice well holes and the orifice sizes (the width and height of the sluice holes), the flow-through requirements of the culvert sluice crossing the dike with different flows can be met.

[0041] (3) Adjust the original open caisson structure to a cylindrical gate well structure, and adjust the cantilever bending structure of the pier to a two-way slab stress structure of the cylinder, effectively improving the stress condition of the culvert gate structure and reducing the thickness of the pier.

[0042] (4) Determine the optimal layout plan by adjusting the length of the gate well and the joint position of the upstream / downstream culvert box passing through the dike, meet the requirements of the safety and stability of the gate well under different operating conditions, and at the same time optimize the structural dimensions of the gate well and the foundation treatment measures.

[0043] (5) By adjusting the position of the gate well on the dike slope and the lengths of the upstream / downstream culvert boxes passing through the dike, the height of the inlet / outlet retaining wall, the length of the bottom slab, and the earth pressure behind the wall can be effectively reduced, and the foundation treatment measures of the retaining wall can be optimized.
