Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a large-diameter ultra-long pile foundation construction platform in water of a gravel layer with little filling. Background Art

[0002] Bailizhou Yangtze River Bridge is located in Zhijiang City, Hubei Province, in the northwest of Jianghan Plain. The bridge site belongs to the river alluvial plain landform. It adopts a main span 890m double-tower single-sided UHPC composite hybrid beam cable-stayed bridge. Due to the water level and geological conditions, the piling ship cannot enter the site to complete the platform erection or steel casing installation. The floating crane construction is also greatly restricted. In addition, the steel casing under the super-thick pebble stratum of the project needs to be further lowered after the hole is drawn. The construction platform is a prerequisite for the construction of the pile foundation steel casing. The main pier platform of the project must be designed as a steel pipe pile platform.

[0003] The main pier is located in the water. First, a construction platform is built, and steel casing is installed. Then, a drilling rig is used for drilling construction. After the steel cage is processed into shape in the steel bar yard, it is transported to the site by a flatbed truck and hoisted by a crawler crane. The concrete is transported to the site by a tank truck for pouring. Considering the irregular arrangement of the circular pedestal pile foundation of the project, the pile foundation construction area generally adopts traditional load-bearing beams, Bailey beams and distribution beam structures. During the pile foundation construction, the main load-bearing beams and Bailey beams need to be continuously dismantled. In order to ensure the stability of the platform, the traditional Bailey beams and load-bearing beam structures are tightly matched and not easy to disassemble. Even if they are disassembled, the local stability of the platform will deteriorate, which will bring great inconvenience to the construction. Moreover, if the platform structure becomes unstable, there will be particularly serious safety hazards.

[0004] Therefore, the present invention provides a large-diameter and ultra-long pile foundation construction platform in water of a pebble layer with little filler to meet the demand. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a large-diameter ultra-long pile foundation construction platform in water with a small amount of filling gravel layer by setting a connection component, a Bailey beam component and a splicing component. The setting of the connection component allows the block-section steel and the Bailey beam to be quickly spliced ​​together, and the stability at the connection position is good. The block-section steel structure can be disassembled separately, and the stability of the overall structure of the platform will not be affected during the local disassembly process. The advantage of such a design is that during construction, when it is necessary to use a drilling rig to drill holes on the platform, the local platform can be disassembled in the block-section steel area of ​​the platform. The block-section steel combined with the splicing component can not only greatly improve the efficiency of platform disassembly and assembly, but also will not affect the stability of other areas of the platform during the disassembly and assembly process, thereby improving the safety of the entire construction process. The above setting can solve the problem of poor stability of a certain area after the construction platform is disassembled during use.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] Optionally, the connecting assembly includes a connecting frame fixedly connected to one end of the Bailey beam, a connecting column is inserted into the connecting frame, and a plurality of groups of linearly arranged connecting seats are arranged outside the connecting column. A first connecting piece is installed on the side of the connecting seat away from the Bailey beam, and a second patterned steel plate is installed on the top of the first connecting piece and the block section steel.

[0010] Optionally, a first top groove is formed at the top of the first connecting member, first side grooves are formed at both sides of the first connecting member, a first bottom groove is formed at the bottom of the first connecting member, and a first triangular reinforcement rib is fixedly connected to the middle position of the first connecting member.

[0011] Optionally, a connection clamping block adapted to the shape of the first side groove is fixedly connected to one side of the connection seat, and the connection seat and the first connecting member are clamped and fixed by the connection clamping block.

[0012] Optionally, a first stabilizing frame is fixedly connected inside the first connecting member, a first stabilizing frame clamping block adapted to the shape of the first bottom groove is fixedly connected to the top of the first stabilizing frame, a second stabilizing frame clamping block adapted to the shape of the first top groove is fixedly connected to the bottom of the first stabilizing frame, and the first connecting member and the first stabilizing frame are screwed and fixed by bolts.

[0013] Optionally, the top of the main beam column is fixedly connected with a main beam clamping block adapted to the shape of the first bottom groove, and the bottom of the second patterned steel plate is fixedly connected with a patterned steel second clamping block adapted to the shape of the first top groove.

[0014] Optionally, the splicing assembly includes a second connecting member fixedly connected to the top of one side of the segmented steel, a third connecting member fixedly connected to the bottom of the segmented steel on the same side as the second connecting member, and the same second stabilizing frame is inserted into one side of the second connecting member and the third connecting member.

[0015] Optionally, a second top groove is formed on the top of the second connecting member, a second side groove is formed on one side of the second connecting member, a second triangular reinforcement rib is fixedly connected to the middle position of the second connecting member, a third side groove consistent with the shape of the second side groove is formed on one side of the third connecting member, a third bottom groove is formed on the bottom of the third connecting member, a third triangular reinforcement rib is fixedly connected to the middle position of the third connecting member, the upper and lower ends of the block section steel away from the side of the second connecting member are fixedly connected with steel clamping blocks matched with the shape of the second side groove, and the bottom of the second patterned steel plate is fixedly connected with a patterned steel first clamping block matched with the shape of the second top groove.

[0016] Optionally, a first adapter block matching the shape of the second side groove and the second top groove is fixedly connected to the top of the second stabilizing frame, and a second adapter block matching the shape of the third side groove is fixedly connected to the bottom of the second stabilizing frame.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up Bailey beam components and splicing components, the construction platform provided by this application is mainly composed of Bailey beams, main beams and block-section steel. The Bailey beams are mainly distributed on both sides of the platform, and the block-section steel is mainly distributed in the middle of the platform. The setting of the connection components allows the block-section steel and the Bailey beams to be quickly spliced ​​together, and the stability at the connection position is good. Furthermore, the block-section steel structures can be disassembled separately, and the stability of the overall structure of the platform will not be affected during the partial disassembly process. The advantage of such a design is that during construction, when it is necessary to use a drilling rig to drill holes on the platform, the partial platform can be disassembled in the block-section steel area of ​​the platform. The block-section steel combined with the splicing component can not only greatly improve the efficiency of platform disassembly and assembly, but also will not affect the stability of other areas of the platform during the disassembly and assembly process, thereby improving the safety of the entire construction process.

[0019] By setting the first bow frame and the second bow frame in the Bailey beam assembly, the second bow frame that matches the shape of the first bow frame is installed at the bottom of the first patterned steel plate, and the two can be snapped together by the shape adaptation effect, thereby achieving a fixing effect. Such a setting uses the structure of the Bailey beam itself to install and fix the first patterned steel plate, saving installation costs and improving the installation efficiency between the first patterned steel plate and the Bailey beam. Furthermore, multiple groups of first patterned steel plates are spliced ​​together through splicing parts, and the splicing parts are distributed on both sides of the first patterned steel plate, presenting a stepped plate structure. Such a setting allows the first patterned steel plates to fit more firmly, and the connection position is flatter and more beautiful.

[0020] By setting the first connecting member in the connecting assembly, the overall structure of the first connecting member can be coordinated with multiple components, and the locking structure for different components is also different. The first connecting member is formed in one piece, which is more efficient and convenient in both processing and production as well as transportation. Multiple notches are set in the first connecting member, and these notches can achieve the effect of "one slot for multiple uses", thereby improving the practicality of the first connecting member.

[0021] In the splicing assembly, the shapes and sizes of the first side groove, the second side groove and the third side groove are exactly the same, the shapes and sizes of the first bottom groove and the third bottom groove are also exactly the same, and the shapes and sizes of the connecting clip blocks and the steel clip blocks are also exactly the same. The reason for this arrangement is to make the construction structure inside the entire construction platform as consistent as possible in outline and size. This not only improves the versatility between structures, but also makes it easier to grasp the size during the production process, requires fewer molds during the processing process, reduces costs, makes the process simpler, and increases production efficiency.

[0022] By setting up a second stabilizing frame in the splicing assembly, during the construction process, after the block-section steel in a certain area is disassembled, the second stabilizing frame can be installed in the area. The second stabilizing frame will support and fix the disassembled block-section steels to improve the firmness of the block-section steels in the area. The first adapter and the second adapter on the second stabilizing frame can both adapt to the structure on the block-section steel, and use the adaptation effect to complete the clip-on fixation. This fixing method once again follows the concept of "one slot for multiple uses".

[0023] In the present application, the setting of each group of connecting structures is simple and reasonable, and the multiple connecting structures are consistent in both structural outline and size. Such a setting not only makes the entire platform simpler and more efficient during the construction process, but also makes the construction materials more efficient during the production and manufacturing process. During the use of the platform, even if a certain area is dismantled, it will not affect the stability of the overall structure of the platform, making it suitable for drilling rig drilling construction.

[0056] like Figures 1 to 23 As shown, an embodiment of the present invention provides a large-diameter ultra-long pile foundation construction platform in a gravel layer with little filling, including a Bailey beam 1, a main beam mounting seat 101 is fixedly connected to the bottom of the Bailey beam 1, a main beam column 2 is fixedly connected to the main beam mounting seat 101, a first patterned steel plate 4 is fixedly connected to the top of the Bailey beam 1, and a block-section steel 3 is installed at one end of the Bailey beam 1; a Bailey beam assembly, the Bailey beam assembly is used to form two side parts of the construction platform, and the Bailey beam assembly is respectively connected to the Bailey beam 1 and the first patterned steel plate 4; a connecting assembly, the connecting assembly is used to fix the relative position between the Bailey beam 1 and the block-section steel 3, and the connecting assembly is They are respectively connected with the block-section steel 3 and the Bailey beam 1; the splicing assembly is used to form the middle part of the construction platform, and the splicing assembly is connected with the block-section steel 3. Compared with the traditional platform construction method, the construction platform provided by the present application is mainly composed of Bailey beam 1, main beam column 2 and block-section steel 3, wherein the Bailey beam 1 is mainly distributed on both sides of the platform, and the block-section steel 3 is mainly distributed in the middle position of the platform. The Bailey beam 1 and the block-section steel 3 are connected and fixed by a connecting assembly. The setting of the connecting assembly enables the block-section steel 3 and the Bailey beam 1 to be quickly spliced ​​together, and the stability at the connection position is good. Furthermore, the block-section steel 3 structures can be disassembled separately, and the stability of the overall structure of the platform will not be affected during the partial disassembly process. The advantage of this design is that during construction, when it is necessary to use a drilling rig to drill holes on the platform, the partial platform can be disassembled in the block-section steel 3 area of ​​the platform. The block-section steel 3 combined with the setting of the splicing components can not only greatly improve the efficiency of platform disassembly and assembly, but also will not affect the stability of other areas of the platform during the disassembly and assembly process, thereby improving the safety of the entire construction process.

[0057] As an implementation method in this embodiment, Figures 1 to 8As shown, the Bailey beam assembly includes a second bow frame 402 fixedly connected to the bottom of the first patterned steel plate 4, a first bow frame 103 that matches the contour of the second bow frame 402 is fixedly connected to the top of the Bailey beam 1, both sides of the first patterned steel plate 4 are fixedly connected with a splicing portion 401, and the connection position between the two groups of first patterned steel plates 4 is spliced ​​together by the splicing portion 401. The Bailey beam assembly is distributed on both sides of the entire construction platform. The Bailey beam assembly is mainly composed of two parts, the Bailey beam 1 and the first patterned steel plate 4. The first patterned steel plate 4 is installed on the top of the Bailey beam 1, and the two are fixed by inserting and splicing. After the Bailey beam 1 is manufactured, it itself has a C-shaped structural contour. The two groups of C-shaped structures on the Bailey beam 1 cooperate to form the first bow frame 103 (as shown in FIG. Figure 8 The structure shown in the figure is shown in the figure. The bottom of the first patterned steel plate 4 is installed with a second bow frame 402 that matches the shape of the first bow frame 103. The two can be snapped together by the shape matching effect to achieve a fixing effect. Such a setting uses the structure of the Bailey beam 1 itself to install and fix the first patterned steel plate 4, which saves the installation cost and improves the installation efficiency between the first patterned steel plate 4 and the Bailey beam 1. Furthermore, multiple groups of first patterned steel plates 4 are spliced ​​together by splicing parts 401. The splicing parts 401 are distributed on both sides of the first patterned steel plate 4 and present a stepped plate structure. Such a setting allows the first patterned steel plates 4 to fit more firmly, and the connection position is flatter and more beautiful.

[0058] As an implementation method in this embodiment, Figures 9 to 13 and Fig.17 As shown, the connection assembly includes a connection frame 102 fixedly connected to one end of the Bailey beam 1, a connection column 106 is inserted in the connection frame 102, and a plurality of groups of connection seats 104 arranged linearly are arranged outside the connection column 106. A first connection member 6 is installed on the side of the connection seat 104 away from the Bailey beam 1. The main function of the connection assembly is to connect the Bailey beam 1 and the block-section steel 3 together. The structure that acts as an intermediate connecting bridge is the first connection member 6. One side of the first connection member 6 cooperates with the connection seat 104, and the other side cooperates with the block-section steel 3. In the Bailey beam assembly, multiple groups of Bailey beams 1 are arranged linearly, and connection frames 102 are installed at the upper and lower ends of one side of each Bailey beam 1. The same connection column 106 is inserted between the multiple groups of connection frames 102. Multiple groups of connection seats 104 arranged linearly are also sleeved outside the connection column 106. The connection seats 104 are staggered between the gaps of the connection frames 102 (such as Fig.12 The above positional relationship is set so that the connecting frame 102, the connecting seat 104 and the connecting column 106 cooperate with each other, and multiple groups of connecting frames 102 and connecting seats 104 are limited to each other, thereby making the Bailey beam 1 more integrated.

[0059] In this embodiment, if Figures 9 to 13 , Fig.17 and Fig.21 As shown, a first top groove 601 is provided on the top of the first connecting member 6, first side grooves 602 are provided on both sides of the first connecting member 6, a first bottom groove 603 is provided on the bottom of the first connecting member 6, a first triangular reinforcement rib 604 is fixedly connected to the middle position of the first connecting member 6, a connecting clamping block 105 which is adapted to the shape of the first side groove 602 is fixedly connected to one side of the connecting seat 104, the connecting seat 104 and the first connecting member 6 are clamped and fixed by the connecting clamping block 105, a main beam clamping block 201 which is adapted to the shape of the first bottom groove 603 is fixedly connected to the top of the main beam column 2, and there are two groups of first connecting members 6, which are respectively located at the upper and lower ends of one side of the Bailey beam 1. In the above structure, the two groups of first side grooves 602 are symmetrically distributed and consist of two groove bodies from outside to inside. The size of the groove body located on the outside is smaller than that of the inner groove body. The connecting clamping block 105 installed on one side of the connecting seat 104 matches the shape of the first side groove 602. The length of the first connecting member 6 runs through the length of the entire Bailey beam assembly. When installing the first connecting member 6, it is only necessary to align the first side groove 602 with the position of the connecting clamping block 105 and then directly push the first connecting member 6, so that the first side groove 602 is sleeved on the connecting clamping block 105 to form a locked fixation. The setting of the double-notch structure of the first side groove 602 can greatly improve the firmness of the cooperation between the first connecting member 6 and the connecting seat 104. Further, when the first connecting member 6 is fully pushed in, under the action of the first connecting member 6, the connecting seats 104 on one side of all Bailey beams 1 are clamped into the same first side groove 602, so that the Bailey beam assembly and the first connecting member 6 form a whole structure.

[0060] Specifically, the main beam clamping block 201 at the top of the main beam column 2 matches the shape of the first bottom groove 603 at the bottom of the first connecting member 6. When installing the main beam column 2, first insert the main beam clamping block 201 into the first bottom groove 603, and use the adaptation effect of the shapes of the two to form a pre-fixation, and then screw the bolts onto the two, and use the bolts to lock and fix the two. The first bottom groove 603 and the first top groove 601 are consistent in contour, but the size of the first bottom groove 603 is larger than the size of the first top groove 601. This setting is to make the contact area of ​​the structural cooperation between the main beam clamping block 201 and the first connecting member 6 larger, thereby improving the stability of the main beam column 2 supporting the first connecting member 6.

[0061] Furthermore, the first triangular reinforcement rib 604 is provided in the middle position of the first connecting member 6. The first triangular reinforcement rib 604 is a triangular structure. Such a provision is to improve the strength of the overall structure of the first connecting member 6. Through the provision of the above structure, we can clearly recognize that the overall structure of the first connecting member 6 can be coordinated with a plurality of components, and the locking structure for different components is also different. The first connecting member 6 is integrally formed, which will be more efficient and convenient in both processing and production as well as transportation.

[0062] In this embodiment, if Fig.10 , Fig.19 and Fig.21 As shown, the first connecting member 6 is fixedly connected with the first stabilizing frame 9, the top of the first stabilizing frame 9 is fixedly connected with the first stabilizing frame first clamping block 901 which is adapted to the shape of the first bottom groove 603, the bottom of the first stabilizing frame 9 is fixedly connected with the second stabilizing frame clamping block 902 which is adapted to the shape of the first top groove 601, the first connecting member 6 and the first stabilizing frame 9 are fixedly connected by bolts, and the overall structure of the first stabilizing frame 9 is composed of multiple groups of triangular brackets (such as Fig.19 As shown in the figure, such a structural setting makes it have sufficiently high stability and supporting capacity. The first stabilizing frame 9 is linearly arranged and distributed between the first connecting members 6, so it can support and fix the first connecting members 6 with the help of its tripod structure, thereby improving the stability and rigidity between the two groups of first connecting members 6. Furthermore, the two ends of the first stabilizing frame 9 are inserted and clamped into the two groups of first connecting members 6 through the first clamping block 901 of the stabilizing frame and the second clamping block 902 of the stabilizing frame, and then locked and fixed with bolts. This fixing method once again utilizes the unique structural setting of the first connecting member 6, so that the slot body on the first connecting member 6 can be "one slot for multiple uses", which improves the practicality of the first connecting member 6.

[0063] As an implementation method in this embodiment, Figures 14 to 17 and Figure 20 to Figure 23As shown, the splicing assembly includes a second connecting member 7 fixedly connected to the top of one side of the block section steel 3, a second top groove 701 is opened on the top of the second connecting member 7, a second side groove 702 is opened on one side of the second connecting member 7, a second triangular reinforcing rib 703 is fixedly connected to the middle position of the second connecting member 7, a third connecting member 8 is fixedly connected to the bottom of the block section steel 3 on the same side as the second connecting member 7, a third side groove 801 with the same shape as the second side groove 702 is opened on one side of the third connecting member 8, and a third bottom groove 803 is opened at the bottom of the third connecting member 8. 2. A third triangular reinforcement rib 803 is fixedly connected to the middle position of the third connecting member 8. As described above, the segmented steels 3 are spliced ​​together to form the middle part of the construction platform. The second connecting member 7 and the third connecting member 8 are fixed to the upper and lower ends of one side of the segmented steel 3 in sequence. Among these two groups of connecting members, the second connecting member 7 is mainly used to install and fix the second patterned steel plate 5, and the third connecting member 8 is mainly used to install and fix the main beam 2. However, the first connecting member 6 and the second connecting member 7 both play a connecting role between the segmented steels 3.

[0064] Specifically, the upper and lower ends of the block section steel 3 away from the second connecting member 7 are fixedly connected with a steel clamping block 301 that matches the shape of the second side groove 702, the first connecting member 6 and the top of the block section steel 3 are both installed with a second patterned steel plate 5, the bottom of the second patterned steel plate 5 is fixedly connected with a patterned steel second clamping block 502 that matches the shape of the first top groove 601, and the bottom of the second patterned steel plate 5 is fixedly connected with a patterned steel first clamping block 501 that matches the shape of the second top groove 701. It should be noted that the first side groove 602 and the second side groove The shapes and sizes of 702 and the third side groove 801 are exactly the same, the shapes and sizes of the first bottom groove 603 and the third bottom groove 802 are also exactly the same, and the shapes and sizes of the connecting clamp block 105 and the steel clamp block 301 are also exactly the same. The reason for this arrangement is to make the construction structure inside the entire construction platform as consistent as possible in outline and size. This not only improves the versatility between structures, but also makes it easier to grasp the size during the production process, requires fewer molds during the processing process, reduces costs, makes the process simpler, and increases production efficiency.

[0065] Specifically, when splicing the segmented steel 3, first align the steel clamping block 301 with the second side groove 702 and the third side groove 801, then push the segmented steel 3 directly, so that the steel clamping block 301 is clamped together with the two sets of side grooves to form a pre-fixation, and finally the two are locked and fixed with bolts. On the one hand, this fixing method improves the efficiency of the fixing process, and on the other hand, this segmented splicing method is more efficient and convenient in the later disassembly process.

[0066] Specifically, the second patterned steel plate 5 is mainly divided into two types, one is located at the top of the Bailey beam 1 and the first connecting member 6, and the other is located at the top of the block section steel 3. The two second patterned steel plates 5 are fixed in different ways. First, the second patterned steel plate 5 is located at the top of the Bailey beam 1 and the first connecting member 6, and the bottom of the second patterned steel plate 5 is fixedly installed with a patterned steel second clamping block 502 that matches the shape of the first top groove 601. When installing this type of second patterned steel plate 5, it is necessary to first align the patterned steel second clamping block 502 with the first top groove 601, and then push it straight to complete the pre-fixation, and finally screw in the bolts to complete the locking fixation; Another type of second patterned steel plate 5 has a patterned steel first clamping block 501 that matches the shape of the second top groove 701 fixedly installed at the bottom. The middle position of the second top groove 701 has an inwardly concave structural shape. When installing, the second patterned steel plate 5 only needs to be directly pressed down. During the pressing process, the patterned steel first clamping block 501 at the bottom will not only be adapted to be clamped into the second top groove 701, but also an outwardly protruding structure is set in the middle position of the first clamping block. This structure, combined with the concave structure in the middle position of the second top groove 701, makes the second patterned steel clamped on the top of the block section steel 3 more firmly and stably. Furthermore, a second patterned steel plate 5 only occupies half of the structure on the second top groove 701, and the other half is spliced ​​and fixed by another second patterned steel plate 5 (such as Fig.14 Such a splicing method enables two groups of second patterned steel plates 5 to be simultaneously clamped into the same second top groove 701, and to limit and squeeze each other by virtue of the structural characteristics, thereby improving the compactness and stability of the second patterned steel plates 5.

[0067] In this embodiment, if Figures 14 to 18 As shown, one side of the second connecting member 7 and the third connecting member 8 are both plugged with the same second stabilizing frame 10, the top of the second stabilizing frame 10 is fixedly connected with a first adapter block 11 that is adapted to the shape of the second side groove 702 and the second top groove 701, and the bottom of the second stabilizing frame 10 is fixedly connected with a second adapter block 12 that is adapted to the shape of the third side groove 801. During the construction process, after the disassembly of the block-section steel 3 in a certain area, the second stabilizing frame 10 can be installed in the area, and the second stabilizing frame 10 will support and fix the disassembled block-section steel 3 to improve the firmness of the block-section steel 3 in the area. The first adapter fastener and the second adapter fastener on the second stabilizing frame 10 can both adapt to the structure on the block-section steel 3, and complete the clamping and fixing with the help of the adaptation effect. This fixing method once again follows the concept of "one slot for multiple uses".

[0068] According to the working principle of the present invention, when building a construction platform, the main beam column 2 at the bottom of the Bailey beam 1 on one side of the platform is first installed and fixed. After the main beam column 2 is installed, the Bailey beam 1 is fixed to the main beam in sequence (the construction of the structure up to this point belongs to the existing technology, so it will not be described in detail). After the Bailey beam 1 is fixed, the first patterned steel plate 4 is fixed to the top of the Bailey beam 1. The first patterned steel plate 4 and the Bailey beam 1 are locked and fixed by the first bow frame 103 and the second bow frame 402. After all the first patterned steel plates 4 are fixed, the connecting seat 104 is staggered and fixed to the connecting frames 102 on the Bailey beam 1 by using the connecting column 106. After the connecting seat 104 is fixed, the main beam column 2 at the bottom of the first connecting member 6 is installed first, and then the first connecting member 6 is simultaneously plugged and fixed to the connecting seat 104 and the main beam column 2. Finally, bolts are used to fix the first patterned steel plates 4. The first connecting member 6 is installed and fixed. After the first connecting member 6 is fixed, the first stabilizing frame 9 is fixed inside it. The first stabilizing frame 9 and the first connecting member 6 are pre-fixed by the first stabilizing frame clamping block 901 and the second stabilizing frame clamping block 902, and are locked and fixed with bolts. After the first stabilizing frame 9 is fixed, the block-section steel 3 is fixed on one side of the first connecting member 6. After the first group of block-section steels 3 are fixed, the remaining block-section steels 3 are pre-fixed by the second connecting member 7, the third connecting member 8 and the steel clamping block 301, and are locked and fixed with bolts. After all the block-section steels 3 are spliced ​​and fixed, the second patterned steel plate 5 is inserted and fixed on the top of the block-section steel 3. After all the second patterned steel plates 5 are fixed, the Bailey beam 1 and the main beam column 2 on the other side of the platform are installed and fixed in the same way as above.

[0069] When it is necessary to dismantle the block-section steel 3 in a local area, first dismantle the second patterned steel plate 5 in the area by pulling up the second patterned steel plate 5. After the second patterned steel plate 5 in the area is dismantled, first unscrew the bolts on the block-section steel 3 in the area, and then pull out the block-section steel 3 from the outside to the inside in sequence. After the block-section steel 3 is removed, insert the second stabilizing frame 10 in the area, and finally fix and lock the second stabilizing frame 10 with bolts.
