Description

Technical Field

[0001] The invention relates to setting a sheet pile protection structure in saline-alkali land, and in particular to a saline-alkali land ecological sheet pile construction system and method. Background Art

[0002] In some lake and sea coasts and plateau saline-alkali areas, protection projects need to be set up to prevent flood disasters caused by flood season. Generally, dams are built as flood control projects. However, the construction of dams covers a large area, has a large construction impact, and requires environmental preparation in advance during construction. The overall procedure is relatively complicated. Setting up sheet piles to form protection during the construction of large-scale flood control projects such as dams can not only promote flood control work, but also form the overall engineering structure more quickly to achieve the purpose of preliminary flood control. Especially in salty water environments and highly corrosive environments, ecological sheet piles can better meet environmental requirements.

[0003] At present, in order to achieve better stability and meet the structural reliability during the flood season in combination with the actual geological environment, the sheet piles need to be driven into the ground to a deeper depth, generally up to about 10m, and a 3-5m above-ground section is reserved to form a flood control enclosure structure. Currently, there are no relatively standardized and automated construction measures. Generally, it is necessary to install the sheet piles one by one after the personnel assist in fixing the sheet piles, which is inefficient. In addition, the sheet piles are forced into the ground by hammering during installation, which can easily cause damage and deformation of the sheet piles, reducing the reliability of the protective structure formed by the sheet piles.

[0004] It can be seen that there are still areas that need to be improved in the current sheet pile construction. It should be optimized to improve the efficiency of the construction and ensure that the maintenance structure formed by the sheet pile after construction is more stable and reliable to meet the purpose of flood control. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Summary of the invention

[0005] In order to overcome at least one of the defects mentioned above, the present invention proposes a saline-alkali land ecological sheet pile construction system and method, which achieves efficiency and convenience in sheet pile installation by uniformly setting installation grooves for the sheet piles and assisting installation with clamps, thereby improving the water protection effect of the protective structure after construction and reducing the construction cost of the entire protective structure.

[0006] In order to achieve the above purpose, the construction system disclosed in the present invention can adopt the following technical solutions:

[0007] A saline-alkali land ecological sheet pile construction system, comprising:

[0008] A slotting mechanism is used to open a foundation slot on the ground for installing ecological sheet piles;

[0009] The fixture assembly is used to clamp and fix the ecological sheet pile, bring the ecological sheet pile into the foundation trench during the construction process and install it to the set depth; the fixture assembly includes a fixture body that fits the ecological sheet pile, a guiding structure for guiding the positioning of the ecological sheet pile is arranged at the upper end of the fixture body, and several locking structures for connecting and fixing the ecological sheet pile are also arranged at intervals on the fixture body.

[0010] The lifting and driving / pulling assembly is used to hoist and move the fixture assembly, and align and join adjacent ecological sheet piles during the construction process, and press the ecological sheet pile into the set depth by applying force.

[0011] The operating platform mechanism is used to restrict the fixture assembly from driving the ecological sheet pile to descend, restrict the position of the ecological sheet pile and assist in aligning and joining adjacent ecological sheet piles; the operating platform mechanism includes a main body, and a positioning groove is opened on the main body along the extension direction of the foundation trench, and the positioning groove is used to constrain the descending direction of the fixture assembly and the ecological sheet pile and vertically enter the foundation trench.

[0012] The driving assembly is used to drive the operating platform mechanism to move forward along the foundation trench.

[0013] The above-disclosed ecological sheet pile construction system effectively guarantees the construction position and construction structure of the ecological sheet pile through the pre-construction grooving and subsequent hoisting of each mechanism, can carry out rapid construction in the area to be constructed, improves the construction convenience and automation degree of the protection project, and the formed flood control structure is also stable and reliable, which can meet the flood control requirements.

[0014] Furthermore, the fixture adopted in the present invention can be constructed in various forms, and its structure is not uniquely limited. Here, an optimization is carried out and a feasible option is proposed: the fixture body includes a groove part that fits the ecological sheet pile and wing parts located on both sides of the groove part. When the ecological sheet pile fits to the fixture body, the width on both sides of the ecological sheet pile is greater than the width of the fixture body. When such a scheme is adopted, the fixture body is integrally formed, which can meet the fitting requirements when connecting the ecological sheet pile and avoid the deformation of the ecological sheet pile; and the length of the fixture body is greater than the length of the ecological sheet pile, which can avoid the bottom of the ecological sheet pile touching the groove structure and deforming when driving the ecological sheet pile to descend into the foundation trench.

[0015] Further, when installing the ecological sheet pile onto the fixture body, one end of the ecological sheet pile needs to be abutted against the fixture body for cooperation. To improve the accuracy of the abutment and avoid deformation and damage of the ecological sheet pile when it is tightened and stressed, the structure of the fixture body is optimized to guide the placement of the ecological sheet pile. Here, one feasible option is proposed: the guiding structure includes a plurality of guiding pieces arranged on the fixture body. A guiding gap for accommodating and clamping the ecological sheet pile is formed between the guiding pieces and the fixture body, and a fastening member is further arranged on the guiding piece. The fastening member is movably matched with the guiding piece and is used to press the ecological sheet pile and the fixture body tightly together. When adopting such a scheme, the width of the guiding gap gradually decreases from the free end of the guiding piece to the end connected to the fixture body, so as to form a clamping force on the ecological sheet pile.

[0016] Further, the locking structure is used to fix the ecological sheet pile and maintain the integrity of the ecological sheet pile and the fixture during the hoisting process. The locking structure can adopt various forms of structures, and it is not uniquely limited. Here, one feasible option is optimized and proposed: the locking structure includes a clamping jaw for clamping the ecological package and the fixture body. When adopting such a scheme, the clamping jaw can adopt an elastic structure, and it is clamped under the action of elastic force and is controlled by a traction rope. When the traction rope is tightened to apply a pulling force, the clamping jaw is loosened, so as to realize the separation of the ecological sheet pile and the fixture body.

[0017] Further, when lifting, the fixture assembly is lifted and adjusted by the lifting and driving component. Specifically, when connecting, the structure of the groove part is optimized and one feasible option is proposed: the groove part is provided with a connecting structure for cooperating with the lifting and driving component. When adopting such a scheme, the connecting structure includes a connecting cross plate fixedly connected to the groove part, and a plurality of connecting longitudinal plates arranged on the connecting cross plate. A plurality of connecting holes are arranged on the connecting longitudinal plates, and the lifting and driving component lifts and displaces the fixture main body through the connecting holes.

[0018] Further, in the present invention, the structure adopted by the operation platform mechanism is not uniquely limited. Here, one feasible option is optimized and proposed: the main body includes a frame body. The top of the frame body includes an auxiliary platform, and the positioning groove extends downward from the top of the frame body and penetrates the frame body. When adopting such a scheme, the frame body is composed of a plurality of columns, cross beams and diagonal braces in cooperation, a platform plate is arranged at the top, and a ladder is arranged for climbing to the platform plate from the lower part.

[0019] Further, in the present invention, in order to better perform positioning and assist the ecological sheet piles in assembly, the structure at the positioning groove is optimized here, and one feasible option is proposed: positioning rods extending upward are provided on both sides of the positioning groove, the positioning rods are arranged in pairs, and the distance between a pair of positioning rods is equal to the width of the positioning groove. When adopting such a scheme, the width between the positioning rods is equal to the width of the positioning groove.

[0020] The above content discloses the composition of the construction system. The present invention also provides a corresponding construction process, which will be described below.

[0021] A construction method for ecological sheet piles in saline-alkali land includes:

[0022] Excavate a foundation trench along the designed path so that the width of the foundation trench is greater than the thickness of the ecological sheet pile;

[0023] Clamp and fix the ecological sheet pile and then lift it longitudinally, and perform assembly construction one by one along the extension direction of the foundation trench, so that the ecological sheet pile is pre-installed to a set height and adjacent ecological sheet piles are joined into a whole;

[0024] After assembling several ecological sheet piles, perform lagging backfilling at the assembly location of the foremost ecological sheet pile. While performing the lagging backfilling, adjust the installation depth of the ecological sheet pile and form a final fixed structure.

[0025] The above disclosed construction method improves the construction efficiency by excavating the foundation trench and installing the ecological sheet pile by hoisting, and also ensures the reliability and stability during the construction and installation of the ecological sheet pile. The protective engineering structure formed by the assembly of the ecological sheet pile is stable and reliable, and can also meet the flood control requirements.

[0026] Further, in the present invention, the ecological sheet pile is fixedly connected and lifted for assembly by a fixture assembly. After the ecological sheet pile is pre-installed to a set height, the fixture assembly is removed and the installation construction of the next ecological sheet pile is carried out.

[0027] Furthermore, when limiting the installation direction of the ecological sheet pile, various methods can be adopted to achieve it. Here, it is optimized and one feasible option is proposed: the installation direction of the ecological sheet pile during installation is limited by an operating platform mechanism, and the operating platform mechanism moves forward step by step along the extension direction of the foundation trench to meet continuous construction. When adopting such a scheme, the operating platform mechanism moves forward once every time a set number of ecological sheet piles are installed, and the installation and forward movement are carried out in turn in a cycle.

[0028] Compared with the prior art, some beneficial effects of the disclosed technical solution of the present invention include:

[0029] The present invention improves the installation efficiency and automation level of ecological sheet piles by combining grooving, lifting and hoisting, and positioning and installation, effectively improves the construction convenience of the protection project, and meets the flood control effect of the completed protection project.

[0039] In view of the problems of low construction efficiency, inconvenient operation and low automation level of ecological sheet piles in the prior art, the following embodiments are optimized to overcome the defects in the prior art.

[0040] Embodiment 1

[0041] As Figure 1 shown, this embodiment provides a construction system for ecological sheet piles 5 in saline-alkali land, including:

[0042] The grooving mechanism 1 is used to open a foundation trench 6 for installing the ecological sheet pile 5 on the ground;

[0043] The fixture assembly 4 is used to clamp and fix the ecological sheet pile 5, and during the construction process, the ecological sheet pile 5 is brought into the foundation trench 6 and installed to a set depth; the fixture assembly 4 includes a fixture body that fits the ecological sheet pile 5. At the upper end of the fixture body, a guiding structure is provided for guiding the positioning of the ecological sheet pile 5, and several locking structures 406 for connecting and fixing the ecological sheet pile 5 are also spaced apart on the fixture body.

[0044] The lifting and driving / pulling assembly 3 is used to hoist and move the fixture assembly 4, and during the construction process, align and join adjacent ecological sheet piles 5, and press the ecological sheet pile 5 into the set depth by applying force;

[0045] The operating platform mechanism 2 is used to restrict the fixture assembly 4 from driving the ecological sheet pile 5 to descend, restrict the position of the ecological sheet pile 5, and assist adjacent ecological sheet piles 5 in aligning and joining; the operating platform mechanism 2 includes a main body. Along the extension direction of the foundation trench 6 on the main body, a positioning groove 203 is opened, and the positioning groove 203 is used to constrain the descending direction of the fixture assembly 4 and the ecological sheet pile 5 and vertically enter the foundation trench 6.

[0046] The driving assembly is used to drive the operating platform mechanism 2 to move forward along the foundation trench 6.

[0047] Preferably, in this embodiment, the grooving mechanism 1 can be used as the driving assembly to provide driving force for the operating platform mechanism 2, or a separate driving assembly can be provided on the grooving mechanism 1 to provide driving force for the operating platform mechanism 2. In addition, a driving wheel, a traction rope, etc. can also be separately provided as the driving assembly.

[0048] The ecological sheet pile 5 construction system disclosed in this embodiment effectively guarantees the construction position and construction structure of the ecological sheet pile 5 through the grooving in the early stage of construction and the subsequent hoisting of each mechanism, can perform rapid construction in the area to be constructed, improves the construction convenience and automation degree of the protection project, and the formed flood control structure is also stable and reliable, and can meet the flood control requirements.

[0049] The fixture adopted in this embodiment can be constructed in various forms, and its structure is not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: such as Figure 2 、 Figure 3As shown in the figure, the fixture body includes a groove portion 401 that fits the ecological sheet pile 5 and wing portions 402 located on both sides of the groove portion 401. When the ecological sheet pile 5 is attached to the fixture body, the width on both sides of the ecological sheet pile 5 is greater than the width of the fixture body. When adopting such a solution, the fixture body is integrally formed, which can meet the fitting requirements when connecting the ecological sheet pile 5 and avoid deformation of the ecological sheet pile 5. Moreover, the length of the fixture body is greater than the length of the ecological sheet pile 5. When driving the ecological sheet pile 5 to descend into the foundation trench 6, it can prevent the bottom of the ecological sheet pile 5 from touching the groove structure and deforming.

[0050] Preferably, in this embodiment, the length of the fixture body is greater than the length of the ecological sheet pile 5, and a number of weight reduction structures 407 are provided on the fixture body. The weight reduction structures 407 can be configured as weight reduction holes or weight reduction grooves.

[0051] When installing the ecological sheet pile 5 onto the fixture body, one end of the ecological sheet pile 5 needs to be abutted against the fixture body and cooperate. In order to improve the abutting accuracy and avoid deformation and damage of the ecological sheet pile 5 when it is tightly pressed and stressed, the structure of the fixture body is optimized to guide the placement of the ecological sheet pile 5. One feasible option is adopted in this embodiment: the guiding structure includes a number of guiding pieces 403 provided on the fixture body. A guiding gap for accommodating and clamping the ecological sheet pile 5 is formed between the guiding pieces 403 and the fixture body, and a fastening member 404 is also provided on the guiding pieces 403. The fastening member 404 is movably matched with the guiding pieces 403 and is used to press the ecological sheet pile 5 and the fixture body tightly together. When adopting such a solution, the width of the guiding gap gradually decreases from the free end of the guiding piece 403 to the end connected to the fixture body, thereby forming a clamping force on the ecological sheet pile 5.

[0052] Preferably, the fastening member 404 is a bolt, and the ecological sheet pile 5 is pressed tightly on the fixture body by screwing the bolt.

[0053] The locking structure 406 is used to fix the ecological sheet pile 5 and maintain the integrity of the ecological sheet pile 5 and the fixture during the hoisting process. The locking structure 406 can adopt various forms of structures and is not uniquely limited. One feasible option is optimized and adopted in this embodiment: the locking structure 406 includes a claw for clamping the ecological package and the fixture body. When adopting such a solution, the claw can adopt an elastic structure, and it is clamped under the action of elastic force and is controlled by a traction rope. When the traction rope is tightened to apply a pulling force, the claw is loosened, thereby realizing the separation of the ecological sheet pile 5 and the fixture body.

[0054] Preferably, the claw adopted in this embodiment includes at least two clamping arms. One clamping arm clamps on the back of the fixture body, and the other clamping arm clamps on the surface of the ecological sheet pile 5, thereby clamping the ecological sheet pile 5 and the fixture body tightly.

[0055] When lifting, the fixture assembly 4 is lifted and adjusted by the lifting and extraction assembly 3. Specifically, when connecting, the structure of the groove portion 401 is optimized and one of the feasible options is adopted: the groove portion 401 is provided with a connecting structure 405, and the connecting structure 405 is used to cooperate with the lifting and extraction assembly 3. When adopting such a scheme, the connecting structure 405 includes a connecting cross plate fixedly connected to the groove portion 401, and a plurality of connecting longitudinal plates arranged on the connecting cross plate. A plurality of connecting holes are arranged on the connecting longitudinal plates, and the lifting and extraction assembly 3 lifts and displaces the fixture body through the connecting holes.

[0056] Preferably, the fixture body is lifted by the lifting and extraction assembly 3, lifted to a vertical state, and then translated to the installation position and lowered for installation. At the same time, during the installation process, the lifting and extraction assembly 3 applies a vibration force to the fixture body through the vibration head to help the fixture body stably descend to the set depth.

[0057] In this embodiment, the structure adopted by the operation platform mechanism 2 is not uniquely limited. Here, it is optimized and one of the feasible options is proposed: as Figure 4 、 Figure 5 shown, the main body includes a frame body. The top of the frame body includes an auxiliary platform 201, and the positioning groove 203 extends downward from the top of the frame body and penetrates the frame body. When adopting such a scheme, the frame body is composed of a plurality of columns, cross beams and diagonal braces, a platform plate is arranged at the top, and a ladder is arranged for climbing from the lower part to the platform plate.

[0058] In this embodiment, in order to better position and assist the ecological sheet pile 5 for assembly, the structure at the positioning groove 203 is optimized in this embodiment, and one of the feasible options is adopted: positioning rods 202 extending upward are arranged on both sides of the positioning groove 203. The positioning rods 202 are arranged in pairs, and the distance between a pair of positioning rods 202 is equal to the width of the positioning groove 203. When adopting such a scheme, the width between the positioning rods 202 is equal to the width of the positioning groove 203.

[0059] Embodiment 2

[0060] The content of the above Embodiment 1 discloses the composition of the construction system. This embodiment also provides a corresponding construction process, which will be described below.

[0061] A construction method for saline-alkali land ecological sheet piles 5 includes:

[0062] S01: Excavate a foundation trench 6 along the designed path so that the width of the foundation trench 6 is greater than the thickness of the ecological sheet pile 5;

[0063] S02: Clamp and fix the ecological sheet pile 5 and lift it longitudinally. Assemble and construct one by one along the extension direction of the foundation trench 6, so that the ecological sheet pile 5 is pre-installed to the set height, and adjacent ecological sheet piles 5 are connected into a whole;

[0064] S03: After assembling several ecological sheet piles 5, carry out lagging backfill at the assembly position of the frontmost ecological sheet pile 5. While carrying out the lagging backfill, adjust the installation depth of the ecological sheet pile 5 and form the final fixed structure.

[0065] The above disclosed construction method improves the construction efficiency by excavating the foundation trench 6 and installing the ecological sheet pile 5 by hoisting, and also ensures the reliability and stability during the construction and installation of the ecological sheet pile 5. The protective engineering structure formed by the assembly of the ecological sheet pile 5 is stable and reliable, and can also meet the flood control requirements.

[0066] In this embodiment, the ecological sheet pile 5 is fixedly connected and lifted and assembled by the fixture assembly 4. After the ecological sheet pile 5 is pre-installed to the set height, the fixture assembly 4 is removed and the installation construction of the next ecological sheet pile 5 is carried out.

[0067] When limiting the installation direction of the ecological sheet pile 5, various methods can be used to achieve it. This embodiment is optimized and one feasible option is adopted: the installation direction of the ecological sheet pile 5 during installation is limited by the operation platform mechanism 2, and the operation platform mechanism 2 moves forward step by step along the extension direction of the foundation trench 6 to meet continuous construction. When adopting such a scheme, the operation platform mechanism 2 moves forward once every time a set number of ecological sheet piles 5 are installed, and the installation and forward movement are carried out in turn in a cycle.

[0068] The above discloses the construction method, and here an example is listed for illustration:

[0069] The ecological sheet pile 5 structure body is 18 mm thick. After being connected by buckles, it forms a sheet pile body with a thickness of 18 cm and a width of 0.718 m. The length of the sheet pile can be freely determined according to the anti-seepage depth requirements. The ecological sheet piles 5 are interlocked through the grooves and joints at both ends to form an integral continuous revetment wall.

[0070] The implementation steps of this method include:

[0071] 1: Construction of the dam body grooving working surface. The working surface width of the grooving machine is 6 meters. It is necessary to excavate the original dam along the grooving center line, and then fill it together with the dam after the ecological plate is installed.

[0072] Specifically, the grooving machine is composed of a grooving tooth chain, a support rod and a pulley block, and a power system (which can be formed by removing the front bucket of an excavator).

[0073] The lengths of the grooving tooth chain and the support rod are calculated according to the grooving depth.

[0074] The travel route of the grooving machine is carried out according to the grooving center line given in the design. Grooving work is carried out at a certain angle, not vertically. The groove width is 200 mm to 300 mm. (Some salt lumps are soluble in groundwater. Grooving can be carried out in the way of forward grooving and reverse sand cleaning to clean the solids insoluble in water out of the ground.)

[0075] 2: Use a special grooving machine to mechanically groove the existing dam body. The groove width is 200 mm to 300 mm, and the groove depth is determined by subtracting the height exposed on the grooving surface from the total depth of the ecological sheet pile 5 (4 m to 12.5 m in this project).

[0076] 3: Hoisting construction: Through the auxiliary hoisting construction operation platform and the ecological sheet pile 5 hoisting construction device, the construction of the ecological sheet pile 5 is carried out.

[0077] Use the hoisting construction device to lift the ecological sheet pile 5 to a fixed position. Two people stand on the operation platform to manually align the U-shaped card slot. After fixing, slowly lower the ecological board and adopt high-frequency downward vibration to ensure that the bottom of the sheet pile enters the design depth.

[0078] The operation platform consists of a main structure and the hoisting construction operation area of the ecological sheet pile 5. The main structure includes the top operation surface, the personnel climbing stairs, the bottom sliding module, the structure reinforcement module, etc.

[0079] Use a self-made hoisting device to carry out the construction of the ecological sheet pile 5; the hoisting device includes a steel sheath with fastening bolts and a clamp. The clamp fixes the steel sheath with the fastened bolts and the ecological sheet pile 5, and is connected to the pile driver by a steel wire rope for secondary protection to prevent the sheet pile from slipping due to vibration.

[0080] When lifted to the fixed position, two people stand on the operation platform to manually align the U-shaped card slot. After fixing, slowly lower the ecological board and adopt high-frequency downward vibration to ensure that the bottom of the sheet pile enters the design depth.

[0081] The above are the implementation manners listed in this embodiment, but this embodiment is not limited to the above optional implementation manners. Those skilled in the art can obtain many other implementation manners by arbitrarily combining the above manners. Anyone can obtain various other forms of implementation manners under the inspiration of this embodiment. The above specific implementation manners should not be understood as limiting the protection scope of this embodiment. The protection scope of this embodiment should be defined by the claims.
