Description

Technical Field

[0001] The present invention relates to the field of building construction, and specifically to a river channel separation and water blocking structure and construction method. Background Art

[0002] With the increasing emphasis on ecological environment protection in urban construction, the requirements for green construction are also getting higher and higher. The key difficulties in river channel construction are that it is difficult to drain the accumulated water and silt in the construction pit, and construction waste is likely to flow into the river, causing water quality damage, which seriously affects the ecological environment construction. Traditional Larssen steel sheet piles are difficult to drive into the ground when encountering complex geological conditions such as hard soil layers or soil layers with large frictional resistance. When pulling them out, it will also cause great disturbance to the surrounding soil mass and affect the surrounding existing structures. In severe cases, it will lead to foundation settlement and damage to the existing structures. Therefore, the present invention proposes a river channel construction plan to solve the above problems. The separation construction method proposed by the present invention not only facilitates the layout work at the river channel construction site, but also facilitates the control of the surrounding water quality, protects the ecological environment, and efficiently and economically solves the problems and improves the project quality. Summary of the Invention

[0003] To solve the above technical problems, the present invention proposes a river channel separation and water blocking structure and construction method. By adopting a separation construction method, the whole construction area is divided into several parts for synchronous construction, which improves the construction efficiency and can timely check the water leakage points and make preventive measures as early as possible.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A river channel separation and water blocking structure, characterized in that: it includes a water blocking plate, and a connecting structure one and a connecting structure two are respectively arranged on the water blocking plate. The connecting structure one and the connecting structure two are detachably connected. When adjacent two water blocking plates are installed, the connecting structure one on the latter water blocking plate is installed in the connecting structure two on the former water blocking plate to achieve fixation. It also includes a soil breaking structure for breaking the soil mass, and the soil breaking structure is installed below the water blocking plate.

[0006] As a preferred technical solution of the present invention: the cross-section of the water blocking plate is wavy. The connecting structure one and the connecting structure two are respectively installed on the end faces on opposite sides of the water blocking plate. The soil breaking structure is installed on the end face below the water blocking plate and between the connecting structure one and the connecting structure two.

[0007] As a preferred technical solution of the present invention: the connecting structure one is a hollow ring, and the connecting structure two is a hollow sleeve. When adjacent two water blocking plates are installed, the hollow ring is inserted into the hollow sleeve.

[0008] As a preferred technical solution of the present invention: the soil-breaking structure is an axe body, and the axe body is provided with a connecting part for connecting with the lower end surface of the water-blocking plate and an axe blade part for breaking the soil body. The connecting part and the axe blade part are arranged opposite to each other, and the axe body is fixedly connected to the lower end surface of the water-blocking plate through the connecting part.

[0009] In the above structure: A river channel separation water-blocking structure proposed by the present invention includes a water-blocking plate, on which a connecting structure one, a connecting structure two and a soil-breaking structure are respectively arranged. When it is necessary to place the water-blocking plate at a specified position, the water-blocking plate is vertically inserted into the soil layer through the soil-breaking structure, and then the connecting structure one on the latter water-blocking plate is installed in the connecting structure two on the former water-blocking plate until the two water-blocking plates reach the same level and are fixed. The water-blocking plates are connected and fixed in sequence through the connecting structure one and the connecting structure two at the head and tail to form a fence. Since the material of the water-blocking plate has certain elastoplasticity, the water-blocking plate can be arranged in an arc or arch shape when needed. After forming a sealed area, subsequent operations such as pumping water can be carried out. The river channel separation water-blocking structure is suitable for the installation and fixation of the fence in the construction area of the river channel, and its unique design is also better suitable for the construction of silty soil. However, if there are other situations where this structure can be used, it can also be constructed independently.

[0010] A row of pointed soil-breaking structures are installed on the lower end surface of the water-blocking plate, which can better insert the fence into the soil. When the lower end surface of the fence enters a deep soil layer, there can still be a good entry effect. In addition, through the arranged soil-breaking structure, when installing the river channel separation water-blocking structure, the impact force on the surrounding soil body is small, reducing the damage to the surrounding soil and the influence on the surrounding structures.

[0011] The connecting structure between the water-blocking plates adopts the design of a hollow ring and a hollow sleeve, which makes the connection between the single water-blocking plates more compact and the water-blocking effect better. When the water-blocking plates are inserted into soil such as silty soil, saturated soil, and silty clay, a vacuum negative pressure state will be generated at the connecting structure. The design of the hollow ring and the hollow sleeve will destroy the negative pressure state on its surface when inserting the water-blocking plates, making the installation easier and more compact. The same is true when disassembling.

[0012] A river channel separation construction method is characterized by including the following steps:

[0013] S1: First, determine the construction area, and then install a fence on the periphery of the construction area. The riverside adjacent to the construction area is in a non-blocking form, and then the area within the fence is divided into blocks according to the section division of different construction sites, so that each separate block bears the same water flow pressure;

[0014] S2: Conduct zoning coding for each sub-block within the enclosure area. The size of each sub-block is averaged. After the coding is completed, pump water outwards in sequence from the middle point sub-block to the outside in a manner from the inside to the outside.

[0015] S3: First, pump out the accumulated water in the central point sub-block, and evenly pump the accumulated water in the middle point sub-block into the adjacent outer sub-blocks. After the accumulated water in the central point sub-block is pumped out, construction can be carried out.

[0016] S4: During the construction process, observe whether there is any water leakage between adjacent sub-blocks. If there is, repair it in a timely manner. After the construction of the central point sub-block is completed, pump water for the outer sub-block adjacent to the central point sub-block, and evenly pump the accumulated water in the outer sub-block adjacent to the central point sub-block into the adjacent outer sub-blocks. After the accumulated water is pumped out, carry out construction on it. Repeat the above operations until the water in the outermost sub-block within the construction area is pumped into the river outside the construction area, and carry out construction on the outermost sub-block. After the construction is completed, the construction of each sub-block within the construction area is completed.

[0017] S5: After the construction of all sub-blocks is completed, remove the enclosures within the construction area in sequence, then clean the construction waste within the construction area, and transport the construction waste out of the construction area.

[0018] As a preferred technical solution of the present invention: In step S1, the outermost enclosure of the construction area is arranged in a straight line, arc, and arch shape. When the flow rate of the construction river is small and the flow velocity is slow, the outermost enclosure is arranged in a straight line shape. When the flow rate of the construction river is large and the flow velocity is fast, the outermost enclosure is arranged in an arc or arch shape.

[0019] As a preferred technical solution of the present invention: In steps S2 and S3, conduct A-J coding for the sub-blocks within the construction area. The coding of the central point sub-blocks is the C sub-block and the H sub-block. Coding outwards from the central point sub-block are the B sub-block and the G sub-block, the D sub-block and the I sub-block, the A sub-block and the F sub-block, and the E sub-block and the J sub-block. First, pump out the accumulated water in the C and H sub-blocks, and evenly pump the accumulated water in the C sub-block into the B and D sub-blocks; pump the accumulated water in the H sub-block into the G and I sub-blocks. After the accumulated water in the C and H sub-blocks is pumped out, construction can be carried out.

[0020] As a preferred technical solution of the present invention: After the construction of the C sub-block and the H sub-block is completed, synchronously carry out construction on the B sub-block, D sub-block, G sub-block, and I sub-block, and respectively pump the accumulated water in the four sub-blocks into the adjacent outer sub-blocks. Finally, pump the accumulated water in the outermost A sub-block, E sub-block, F sub-block, and J sub-block into the river.

[0021] As a preferred technical solution of the present invention: in step S5, when removing the outermost enclosure in the demolition construction area, it needs to be slowly pulled out. When using a work vehicle to remove the enclosure, the enclosures are removed sequentially from the inside out. When using a work boat to remove the enclosure, the enclosures are removed sequentially from the outside in.

[0022] In the above structure: A river separation construction method proposed by the present invention, compared with the traditional construction method, the present invention conducts layered treatment on the fast-flowing river water, gradually reducing the impact of the river on the enclosure, forming multiple buffer areas, and increasing the safety factor of construction. Pumping water region by region can relieve the stress on the enclosure, pump the accumulated water in the construction area to the adjacent area, improve the construction efficiency, and also facilitate the layout of construction site personnel, equipment layout, and the arrangement of construction plans, saving the construction period and reducing the construction cost.

[0023] The water-facing surface of the enclosure formed by fixing the water-blocking plates end to end can adopt a straight-line, arc-shaped, or arched enclosure layout form, which can provide greater anti-overturning force, ensure the safety of the construction environment in the pit, and also ensure that water will not easily flow into the pit. When the flow rate is too large and the flow velocity is too fast, a double-layer structure can be used for the enclosure.

[0024] By field investigation of the flow situation of the river, if the river has a small flow rate and slow velocity, the enclosure can adopt a straight-line shape. If it encounters the river conditions of large flow rate and fast velocity, the outermost enclosure is arranged in an arc shape or an arched shape to obtain greater anti-overturning force. The outermost enclosure can also be arranged in a double-interception form according to the actual situation to achieve a better water-blocking effect.

[0025] For the riverside adjacent to the bank, a non-intercepting form can be adopted, using the reduced pressure of the river flow velocity to resist the action of part of the river on the side enclosure, improving the safety factor of the side enclosure.

[0026] The enclosures on both sides of the bank can have a certain distance from the bank, and the river does not stop flowing throughout the construction process. For rivers with large fluidity, this arrangement greatly increases the safety factor and does not affect the normal use of the river water quality. Using the pressure reduction area of the river flow velocity to resist part of the pressure generated by the river itself relieves the stress on the enclosure and improves the reliability of the enclosure. [[ID=,17]]

[0027] Arrangement of equipment on the river: First, a small lifting equipment can be directly set up on the bank to lay the river separation water-blocking structure, and the construction of the internal construction area of the river can be completed in combination with construction machinery;

[0028] Second, if the river width is large and it is impossible to arrange working machines on both sides of the bank, a work boat can be used and the equipment can be placed on the work boat for construction;

[0029] Third, an operation platform can also be set up in the river under environmental permission for subsequent construction.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] By adopting the river channel separation construction method in the present invention, the turbulent river water can be stratified, gradually reducing the impact of the river on the enclosure, forming multiple buffer areas, increasing the safety factor of construction, and pumping water area by area, which can relieve the stress on the enclosure, pump the accumulated water in the construction block to the adjacent block, and effectively improve the construction efficiency.

[0032] The river channel separation water-blocking structure in the present invention has a simple structure, is easy to use, facilitates the layout of personnel, equipment and the compilation of construction plans at the construction site, saves the construction period and reduces the construction cost;

[0033] The lower section of the water-blocking plate in the river channel separation water-blocking structure adopts a row of pointed soil-breaking structures, which can better insert the enclosure into the soil. When the lower end of the enclosure enters a deep soil layer, there can still be a good entry effect. In addition, adding the soil-breaking structure makes the impact on the surrounding soil mass smaller when installing this water-blocking structure, reducing the damage to the surrounding soil mass and the impact on the surrounding structures;

[0034] The connection structure 1 and connection structure 2 between the water-blocking plates in the river channel separation water-blocking structure respectively adopt the designs of hollow rings and hollow sleeves, which makes the connection between the single water-blocking plates closer and the water-blocking effect better. When the water-blocking plates are inserted into soil such as silty soil, saturated soil, and silty clay, a vacuum negative pressure state will be generated at the connection structure, and the designs of the hollow rings and hollow sleeves will destroy the negative pressure state on their surfaces when inserting the water-blocking plates, making the installation easier and tighter. The same is true when disassembling. Brief Description of the Drawings

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0047] The present invention is designed in view of the phenomena such as a large amount of water accumulation and great difficulty during construction in the river channel, and it is difficult to control the water-free construction environment in the pit, aiming to solve the problem of difficult control of accumulated water and silt in the construction pit. The specific solution is as follows:

[0048] As Figure 1-9 shown, the present invention proposes a river channel separation water-blocking structure, including a water-blocking plate 2. The first connection structure 1 and the second connection structure 4 are respectively arranged on the water-blocking plate 2. The first connection structure 1 and the second connection structure 4 are detachably connected. When adjacent water-blocking plates 2 are installed, the first connection structure 1 on the latter water-blocking plate 2 is installed in the second connection structure 4 on the former water-blocking plate 2 to achieve fixation. It further includes a soil-breaking structure 3 for breaking the soil body, and the soil-breaking structure 3 is installed below the water-blocking plate 2.

[0049] The cross-section of the water-blocking plate 2 is wavy. The first connection structure 1 and the second connection structure 4 are respectively installed on the end faces on opposite sides of the water-blocking plate 2. The soil-breaking structure 3 is installed on the end face below the water-blocking plate 2 and is located between the first connection structure 1 and the second connection structure 4.

[0050] The first connection structure 1 is a hollow ring, and the second connection structure 4 is a hollow sleeve. When adjacent water-blocking plates 2 are installed, the hollow ring is inserted into the hollow sleeve.

[0051] The soil-breaking structure 3 is an axe body. The axe body is provided with a connecting portion for connecting with the lower end face of the water-blocking plate 2 and an axe blade portion for breaking the soil body. The connecting portion and the axe blade portion are arranged opposite to each other, and the axe body is fixedly connected to the lower end face of the water-blocking plate 2 through the connecting portion.

[0052] A river channel separation water-blocking structure proposed by the present invention includes a water-blocking plate 2, on which a connecting structure one 1, a connecting structure two 4 and a soil-breaking structure 3 are respectively arranged. When the water-blocking plate 2 needs to be installed at a specified position, the water-blocking plate 2 is vertically inserted into the soil layer through the soil-breaking structure 3, and the connecting structure one 1 on the latter water-blocking plate 2 is installed in the connecting structure two 4 on the former water-blocking plate 2 until the two water-blocking plates 2 reach the same level to achieve fixation. The water-blocking plates 2 are connected and fixed in sequence through the connecting structure one 1 and the connecting structure two 4 at the head and tail to form a fence. Since the material of the water-blocking plate 2 has certain elastoplasticity, the water-blocking plate 2 can be arranged in an arc or arch shape when needed. After a sealed area is formed, subsequent operations such as pumping water can be carried out. The river channel separation water-blocking structure is suitable for the installation and fixation of fences in the construction area within the river channel, and its unique design is also better suitable for the construction of silt soil. However, if there are other situations where this structure can be used, individual construction can also be carried out.

[0053] A row of pointed soil-breaking structures 3 are installed on the lower end surface of the water-blocking plate 2, which can better insert the fence into the soil. When the lower end surface of the fence enters a deep soil layer, there can still be a good entry effect. In addition, through the arranged soil-breaking structure 3, when installing the river channel separation water-blocking structure, the impact force on the surrounding soil body is small, reducing the damage to the surrounding soil and the influence on the surrounding structures.

[0054] The connection structure between the water-blocking plates 2 adopts the design of a hollow ring and a hollow sleeve, which makes the connection between the single water-blocking plates 2 more compact and the water-blocking effect better. When the water-blocking plates 2 are inserted into soil such as silt soil, saturated soil, and silty clay, a vacuum negative pressure state will be generated at the connection structure. The design of the hollow ring and the hollow sleeve will destroy the negative pressure state on its surface when inserting the water-blocking plates 2, making the installation easier and more compact. The same is true when disassembling.

[0055] A river channel separation construction method includes the following steps:

[0056] S1: First, determine the construction area, and then install a fence on the periphery of the construction area. The riverside adjacent to the construction area is in a non-blocking form, and then the area within the fence is divided into blocks according to the section division of different construction sites, so that each individual block bears the same water flow pressure;

[0057] S2: Each block within the fence area is coded for separation. The size of each block is average. After the coding is completed, the water is pumped out from the middle point of the block to the outside in sequence from the inside out;

[0058] S3: First, drain the accumulated water in the central point block, evenly pump the accumulated water in the central point block into the adjacent block outside it. After the accumulated water in the central point block is drained, construction can be carried out;

[0059] S4: During the construction process, observe whether there is any water leakage between adjacent blocks. If there is, repair it in a timely manner. After the construction of the central block is completed, pump out the water from the outer blocks adjacent to the central block, and evenly pump the accumulated water in the outer blocks adjacent to the central block into the adjacent outer blocks. After pumping out the accumulated water, carry out construction on them. Repeat the above operations until the water in the outermost block within the construction area is pumped into the river outside the construction area, and then carry out construction on the outermost block. After the construction is completed, the construction of each block within the construction area is completed;

[0060] S5: After the construction of all blocks is completed, remove the fences within the construction area in sequence, then clean the construction waste within the construction area, and transport the construction waste out of the construction area.

[0061] In step S1, the outermost fence of the construction area is arranged in a straight line, arc, and arch shape. When the flow rate of the construction river is small and the flow velocity is slow, the outermost fence is arranged in a straight line shape. When the flow rate of the construction river is large and the flow velocity is fast, the outermost fence is arranged in an arc or arch shape.

[0062] In steps S2 and S3, the blocks within the construction area are coded from A to J. The codes of the central blocks are block C and block H. Starting from the central blocks and going outwards, they are coded as block B and block G, block D and block I, block A and block F, and block E and block J. First, pump out the accumulated water in blocks C and H, and evenly pump the accumulated water in block C into blocks B and D; pump the accumulated water in block H into blocks G and I. After the accumulated water in blocks C and H is pumped out, construction can be carried out.

[0063] After the construction of block C and block H is completed, synchronously carry out construction on blocks B, D, G, and I, and respectively pump the accumulated water in the four blocks into the adjacent outer blocks. Finally, pump the accumulated water in the outermost blocks A, E, F, and J into the river.

[0064] In step S5, when removing the outermost fence within the construction area, it needs to be slowly pulled out. When using a work vehicle to remove the fence, the fence is removed in sequence from the inside out. When using a workboat to remove the fence, the fence is removed in sequence from the outside in.

[0065] A river separation construction method proposed by the present invention, compared with the traditional construction method, the present invention conducts layered treatment on the turbulent river water, gradually reduces the impact of the river on the fence, forms multiple buffer areas, and increases the safety factor of construction. Pumping water in each area can relieve the stress pressure on the fence, pump the accumulated water in the construction area into the adjacent area, improve the construction efficiency, and is also convenient for the layout of construction site personnel, equipment layout, and the compilation of construction plans, saving the construction period and reducing the construction cost.

[0066] The water-facing side of the enclosure formed by fixing the water-blocking plate 2 at both ends can adopt linear, arc-shaped, or arched enclosure layout forms, which can provide greater anti-overturning force, ensure the safety of the construction environment inside the pit, and also ensure that water does not easily flow into the pit. When the flow rate is too large and the flow velocity is too fast, a double-layer structure can be used for the enclosure.

[0067] By conducting on-site inspections of the river flow conditions, if the river has a small flow rate and slow velocity, a linear enclosure can be adopted. If the river conditions are characterized by a large flow rate and fast velocity, the outermost enclosure can be arranged in an arc shape or an arch shape to obtain greater anti-overturning force. The outermost enclosure can also be arranged in a double-intercept layout according to the actual situation to achieve a better water-blocking effect.

[0068] For the riverside along the bank, a non-intercept form can be adopted, and the pressure reduced by the river flow velocity is used to resist the action of the river on the side enclosure, thereby increasing the safety factor of the side enclosure.

[0069] The enclosures on both sides along the bank can be at a certain distance from the bank, and the river does not stop flowing throughout the construction process. For rivers with large fluidity, this arrangement greatly increases the safety factor and does not affect the normal use of the river water quality. The pressure reduction area of the river flow velocity is used to resist part of the pressure generated by the river itself, alleviating the stress on the enclosure and improving the reliability of the enclosure.

[0070] Arrangement of equipment on the river: First, small lifting equipment can be directly erected on the bank to lay the river-separating water-blocking structure, and with the cooperation of construction machinery, the construction of the internal construction area of the river can be completed.

[0071] Second, if the river width is large and it is impossible to arrange operating machines on both sides along the bank, an operating boat can be used, and the equipment can be placed on the operating boat for construction.

[0072] Third, an operating platform can also be erected in the river when the environment permits for subsequent construction.

[0073] By adopting the river-separating construction method in the present invention, the turbulent river water can be stratified, gradually reducing the impact of the river on the enclosure, forming multiple buffer areas, increasing the safety factor of the construction, and pumping water area by area can alleviate the stress on the enclosure, pumping the accumulated water in the construction block to the adjacent block, effectively improving the construction efficiency.

[0074] The structure of the river-separating water-blocking structure in the present invention is simple, easy to use, convenient for the layout of construction site personnel, equipment, and the arrangement of construction plans, saving the construction period and reducing the construction cost.

[0075] In the water-blocking structure for river channel separation, the lower part of the water-blocking board 2 adopts a row of pointed soil-breaking structures 3, which can better insert the enclosure into the soil. When the lower end of the enclosure enters a deep soil layer, it can still have a good insertion effect. In addition, the addition of the soil-breaking structure 3 reduces the impact force on the surrounding soil during the installation of this water-blocking structure, reducing the damage to the surrounding soil and the impact on the surrounding structures;

[0076] In the water-blocking structure for river channel separation, the connecting structure 1 and the connecting structure 4 between the water-blocking boards 2 respectively adopt the designs of hollow rings and hollow sleeves, which makes the connection between the individual water-blocking boards 2 tighter and the water-blocking effect better. When the water-blocking boards 2 are inserted into soil such as silty soil, saturated soil, and silty clay, a vacuum negative pressure state will be generated at the connection structure. The designs of the hollow rings and hollow sleeves will break the negative pressure state on their surfaces when inserting the water-blocking boards 2, making the installation easier and tighter. The same applies when disassembling.

[0077] The present invention can well solve the problem of water accumulation during construction in the construction pit, especially during construction in turbulent river water. It not only saves the construction period and reduces the construction cost, but also protects the water quality and does not damage the ecological environment. Fundamentally, it solves the difficulties of cumbersome river channel construction and difficult arrangement of construction plans, reducing unnecessary resource waste. When used in combination with the enclosure assembled by the water-blocking board 2, it can effectively resist the impact of water flow, ensure that the dry environment in the construction pit will not be damaged by the water flow, and prevent the waste generated during construction from flowing into the river and causing pollution.

[0078] The present invention has a very high practicality level. It can be reasonably adjusted in different construction environments. The construction plan is very simple, and there are no special requirements for the on-site construction personnel, which is convenient for technical disclosure to the construction personnel. It can be applied to most river channel construction projects.

[0079] This invention patent has great transformation value and practical value, with a wide application range. It can directly create value and can be used as a reference for the same type of river channel construction to reasonably arrange the construction plan to achieve the purpose of cost reduction and efficiency improvement. It meets the relevant requirements of the industry for green construction and protects the environment. In addition, the enclosure designed in combination with this construction plan adopts a special connection structure. When inserted into silty soil, it breaks the negative pressure environment, making it easier to insert and remove for construction.

[0080] The present invention is applicable to most river channel construction projects. Moreover, due to the relatively simple principles of the water-blocking structure and construction method of the present invention, it can be well disclosed to the on-site construction personnel in terms of technology. Among them, the design of the enclosure is ingenious and low-cost, which can well achieve the water-blocking effect, is safe and reliable. Therefore, a small number of such enclosures can be trial-produced first to see if they are practical and promotable, and then mass-produced and widely promoted.

[0081] The above are only the preferred embodiments of the present invention, and are not any other form of limitation to the present invention. Any modification or equivalent change made according to the technical essence of the present invention still belongs to the scope claimed by the present invention.
