DETAILED DESCRIPTION
[0025] The present invention is further described in detail below in conjunction with specific embodiments. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.
[0026] Example 1
[0027] like Figure 1 and Figure 2As shown, this embodiment provides a flood control system structure, which is based on an existing platform 1. A temporary flood control device 3 is arranged on one side of the existing platform 1, and an additional platform 2 is arranged outside the temporary flood control device 3. The existing platform 1 and the additional platform 2 clamp and fix the temporary flood control device 3. The water side (the side close to the river) of the additional platform 2 has a slope 36, and the top of the temporary flood control device 3 extends upward from the existing platform 1. The additional platform 2 includes a first stacking structure 32, and the upper part of the first stacking structure 32 is filled with a soil structure 34. A second stacking structure 35 is arranged outside the soil structure 34. The outer side surface of the second stacking structure 35 and the outer side surface of the first stacking structure 32 form a continuous slope 36, and no cliff-like changes are formed between them. The first stacking structure 32 and the second stacking structure 35 are both made of sandbags.
[0028] The utility model provides a flood control system structure, wherein a temporary flood control device 3 is arranged between the existing platform 1 and the additional platform 2 for temporary flood control needs, and the first stacking structure 32 and the second stacking structure 35 are both made of sandbags, which can prevent scouring and avoid the soil structure 34 being washed away, and are also convenient for subsequent excavation, thereby reducing construction difficulty and construction cost.
[0029] Furthermore, the upper part of the first stacking structure 32 is filled with a soil structure 34, so that the additional platform 2 includes the soil structure 34, which is not entirely made of sandbags, further reducing the construction cost. Since the cost of sandbag stacking is higher than that of soil dumping construction, this can also reduce the construction difficulty of the additional platform 2. On this basis, a second stacking structure 35 is arranged on the outside of the soil structure 34, and the outer side surface of the second stacking structure 35 and the outer side surface of the first stacking structure 32 form a continuous slope 36 to prevent the soil structure 34 from being washed away by river water, so that the soil structure 34 meets the use requirements.
[0030] like Figure 4 As shown, in some preferred cases, the upper part of the second stacking structure 35 completely covers the top of the soil structure 34 to prevent the top of the soil structure 34 from being exposed and causing dust to fly, so as to reduce environmental pollution at the construction site.
[0031] In a preferred manner, the temporary flood prevention device 3 includes a steel sheet pile assembly, the top of the steel sheet pile assembly extends out of the existing platform 1, and the steel sheet pile assembly includes a plurality of steel sheet piles that are sealed and matched in sequence.

[0033] To further reduce costs, an empty groove 33 is formed between the first stacking structure 32 and the temporary flood prevention device 3, and a part of the soil structure 34 is filled in the empty groove 33, which can prevent at least part of the soil structure 34 from being washed away by river water.

[0039] like Figure 3 As shown, in a preferred manner, the top of the reinforcement pile 31 against the temporary flood prevention device 3 extends upwardly from the existing platform 1 .
[0040] In a preferred embodiment, a bank protection ground connecting wall 4 is provided on a side of the existing platform 1 away from the temporary flood protection device 3 .
[0041] In a preferred embodiment, a vertical concrete wall 5 is provided on the top of the revetment ground connecting wall 4 protruding upward.
[0042] In a preferred embodiment, the revetment ground-connecting wall 4 includes vertical walls 41 arranged at intervals, the tops of adjacent vertical walls 41 are supported and connected with top plates 42, some of the reinforcement piles 31 support the top plates 42, and the reinforcement piles 31 are arranged on both sides of the vertical walls 41. When the revetment ground-connecting wall 4 is constructed, a trench is first excavated using a construction machine, and then cast in the trench to form the revetment ground-connecting wall 4, and the reinforcement piles 31 are arranged on both sides of the vertical walls 41 to prevent the hole collapse problem when the trench is excavated for the ground-connecting wall.
[0043] A specific preferred solution: A flood control system structure described in this embodiment includes an existing platform 1 and an additional platform 2, a steel sheet pile assembly is arranged between the existing platform 1 and the additional platform 2, the top of the steel sheet pile assembly extends out of the existing platform 1, and the additional platform 2 includes a first stacking structure 32, the upper part of the first stacking structure 32 is filled with a soil structure 34, and a second stacking structure 35 is arranged on the side of the soil structure 34 away from the steel sheet pile assembly, and the outer side surface of the second stacking structure 35 forms a continuous slope 36 with the outer side surface of the first stacking structure 32, and the first stacking structure 32 and the second stacking structure 35 are both made of sandbags. The steel sheet pile assembly is formed by stacking; the top of the steel sheet pile assembly extends out of the existing platform 1, and the steel sheet pile assembly includes a plurality of steel sheet piles that are sealed and matched in sequence; the distance from the top of the first stacking structure 32 to the steel sheet pile assembly is greater than the distance from the bottom of the first stacking structure 32 to the steel sheet pile assembly, so that an empty groove 33 is formed between the first stacking structure 32 and the steel sheet pile assembly, and a part of the soil structure 34 is filled in the empty groove 33; a support reinforcement structure 7 is provided on the existing platform 1, and the support reinforcement structure 7 abuts against the part of the steel sheet pile assembly extending out of the existing platform 1, and the support reinforcement structure 7 is preferably formed by stacking sandbags. The existing platform 1 is provided with reinforcement piles 31, at least one of mixing piles and rotary jet piles. A revetment ground connection wall 4 is provided on the side of the existing platform 1 away from the steel sheet pile assembly. A vertical concrete wall 5 is provided on the top of the revetment ground connection wall 4 protruding upward.
[0044] There are several characteristics of the above flood control system architecture:
[0045] The first stacking structure 32 and the second stacking structure 35 are both made of sandbags, which can prevent scouring and prevent the soil structure 34 from being washed away, and are also convenient for later excavation. If stones are filled, scouring can also be prevented, but excavation is difficult. If they are not excavated cleanly, hard obstacles will be formed, which is not conducive to the safety of navigation.
[0046] The temporary flood prevention device 3 includes steel sheet piles. The steel sheet piles serve as flood prevention structures, which are convenient for later dismantling and recycling, thus saving construction costs.
[0047] The support reinforcement structure 7 is used for temporary support reinforcement to prevent the temporary flood prevention device 3 from tipping over to the existing platform 1 due to excessively high water levels in extreme cases.
[0048] The supporting reinforcement structure 7 is made of piled sandbags, which is convenient for later excavation.
[0049] Because part of the soil of the existing platform 1 is filled during construction, and the ground-connected wall construction equipment is heavy, the equipment will be unstable if it goes directly on it, so the existing platform 1 is reinforced with reinforcement piles 31, and the reinforcement piles 31 are preferably at least one of mixing piles and rotary jet piles. If the existing platform 1 is filled with stones, it will cause stones to be encountered when the bank protection ground-connected wall 4 is constructed into a groove, which greatly increases the difficulty of construction. The reinforcement measures of the reinforcement piles 31 can further enhance the resistance of the temporary flood control device 3 and prevent the temporary flood control device 3 from tipping over.
[0050] The part of the existing flood embankment located on the existing platform 1 will be demolished, and the additional platform 2 will be built on the water side of the existing platform 1, and a temporary flood prevention device 3 will be constructed. Both ends of the temporary flood prevention device 3 are sealed and connected to the remaining part of the existing flood embankment to form a temporary flood prevention system;
[0051] Use construction machinery to remove part of the existing flood embankment and construct at least part of the revetment ground-connected wall 4, because the additional platform 2 is set up to prevent the existing platform 1 from shifting and collapsing due to the deadweight of the construction machinery during construction;
[0052] Along the length direction of the existing flood embankment, the additional platform 2, the temporary flood protection device 3 and the revetment ground connection wall 4 all pass through the immersed tube installation path.
[0053] In a preferred embodiment, the top height of the additional platform 2 is lower than the top height of the existing flood embankment; the existing flood embankment can then be excavated to be flush with the top of the additional platform 2, and the soil excavated from the existing flood embankment can be used as a component of the additional platform 2.
[0054] The top height of the additional platform 2 is lower than the top height of the existing flood embankment. Compared with the case where the top height of the additional platform 2 is equal to or higher than the top height of the existing flood embankment, the water area occupied by the additional platform 2 is reduced, and the construction cost of dismantling the additional platform 2 at a later stage is also effectively reduced.
[0055] In a preferred embodiment, the top height of the temporary flood protection device 3 is equal to or higher than the top height of the existing flood protection embankment.
[0056] When the top height of the additional platform 2 is lower than the top height of the existing flood levee, in order to ensure the flood control effect in the area of the existing flood levee to be destroyed, the top height of the temporary flood control device 3 is constructed to be equal to or higher than the top height of the existing flood levee.
[0057] In a preferred manner, the bank protection ground-connected wall 4 includes a ground-connected wall structure and a vertical concrete wall 5 sealed to the upper part of the ground-connected wall structure, so that the two ends of the bank protection ground-connected wall 4 and the vertical concrete wall 5 are sealed to the existing flood embankment, the top height of the ground-connected wall structure is lower than the top height of the existing flood embankment, and the top height of the vertical concrete wall 5 is equal to or greater than the top height of the existing flood embankment.
[0058] In a preferred manner, the top of the ground-connected wall structure is integrally constructed with the upright concrete wall 5 .
[0059] In the above scheme, the area of the existing flood control embankment to be destroyed must first be reinforced. The reinforced boundary line is preferably the same as the river bank. Direct reinforcement poses the risk of construction machinery falling into the river channel 6, so an additional platform 2 is filled in the river channel 6 as an additional platform 2 for construction machinery. The higher the height of the additional platform 2 is filled, the greater the slope of the additional platform 2 facing the water, and the more the filled soil will occupy the river channel, which will affect the width of the river channel and further affect the navigation of ships.
[0060] If the top of the additional platform 2 is made the same height as the top of the existing flood embankment, the water area occupied will increase under the same slope conditions. Therefore, the top of the additional platform 2 to be built will be lower than the top of the existing flood embankment, and the existing flood embankment will be dug lower so that the top of the area to be destroyed in the existing flood embankment is flush with the top of the additional platform 2 to facilitate construction machinery construction. However, this will affect flood control.
[0061] Filling the lowered additional platform 2 can reduce the water area occupied by the additional platform 2, and the amount of filled soil will also be less, because the filled additional platform 2 is only a temporary measure and will be demolished later, so less filled soil is also conducive to the later demolition work. Specifically, a low additional platform 2 is constructed and filled, and the original existing flood embankment area to be destroyed is flattened, so that the top of the existing flood embankment area to be destroyed is flush with the top of the additional platform 2.
[0062] Steel sheet piles are driven on one side of the additional platform 2, and the top of the steel sheet piles is at least 6m above the ground to ensure flood control. In this way, the area of the existing flood embankment to be destroyed can be dug down to the same height as the additional platform 2, which is convenient for construction machinery to construct on the existing platform 1, and the same is true for the other side of the river.
[0063] When constructing an immersed tube tunnel in an inland river, both sides of the river are embankments. The embankments have flood control functions, but when constructing an immersed tube, the embankments at both ends will be temporarily demolished, which will affect flood control. This application mainly provides a flood control system structure and makes full use of existing structures to reduce the cost as much as possible and simplify the construction on the basis of ensuring effective flood control. Combining the prefabricated construction of immersed tubes can achieve flood control and facilitate construction.
[0064] The temporary flood control device 3 uses steel sheet piles, which can be recycled after construction, reduce costs, and achieve short-term use. The vertical concrete wall 5 can achieve long-term flood control, and the demolition stage is relatively easy, so it can be used in the medium term.
[0065] In this embodiment, the construction machinery is preferably a slotting machine or a double-wheel milling machine.
[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
