Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to an anti-overflow base inside an assembled enclosure and a construction method thereof. Background Art

[0002] It is particularly important to fence the construction area as early as possible during the construction of municipal projects. The construction of overflow-proof bases is an important part of the construction fencing operation. Overflow-proof bases can effectively prevent water, sand, slag and other easily lost construction materials in the construction project from spilling into the municipal public areas. The application of overflow-proof bases not only improves the safety of the construction site, but also reduces environmental pollution and resource waste caused by the loss of materials, which has important environmental and economic benefits.

[0003] Existing anti-overflow bases mostly adopt a block structure, that is, multiple masonry blocks are arranged in a certain order and stacked into a water retaining structure. This method requires manual stacking of blocks one by one during the construction process, which is relatively complicated, takes a long time to construct on site, and the construction quality is greatly affected by the technical level of the workers. In addition, since the connection between blocks depends on mortar or cement, the stability and durability of the overall structure are poor, and cracks or falling off are prone to occur, affecting the anti-overflow effect. Therefore, there is an urgent need for an anti-overflow base solution that can be quickly installed and has good stability. Summary of the invention

[0004] In order to shorten the construction period of the anti-overflow base, the present application provides an anti-overflow base inside an assembled enclosure and a construction method thereof.

[0005] In the first aspect, the present application provides an assembled enclosure inner side anti-overflow base, which adopts the following technical solution: A prefabricated anti-overflow base inside a barrier comprises a blocking block, the bottom end of the blocking block is used to be buried in a concrete pavement, a plurality of the blocking blocks are provided and abut against each other, a positioning block is fixedly connected to one side of the blocking block, a positioning groove is provided on the other side of the blocking block, the positioning groove is used to accommodate the positioning block on the adjacent blocking block, a chiseling-free grout-stopping strip is provided at the bottom end of the blocking block, and the chiseling-free grout-stopping strip is used to be buried in the concrete pavement.

[0006] By adopting the above technical scheme, the blocking block provided with the non-roughening grouting strip is fixed by cast-in-place method. The non-roughening grouting strip can increase the contact area between the blocking block and the concrete pavement layer, thereby enhancing the bonding effect and improving the stability of the blocking block; since the two adjacent blocking blocks are matched with each other through the clamping connection of the positioning block and the positioning groove, the positioning effect between the positioning block and the positioning groove helps to simplify the construction process, and can shorten the construction period while ensuring the construction quality; the setting of the positioning block also extends the penetration path of the water flow, thereby helping to enhance the water retaining effect.

[0007] Optionally, the blocking block includes an embedded block and a water retaining block, the embedded block is used to be buried in the concrete pavement, the water retaining block is arranged at the top of the embedded block, and a fixing component for fixing the water retaining block and the embedded block is arranged between the water retaining block and the embedded block.

[0008] By adopting the above technical solution, the blocking block is a separate structure. When the anti-overflow base needs to be removed after the construction is completed, the embedded block buried in the concrete pavement layer can be retained, and then the water retaining block above it can be removed. The removal process will not damage the original pavement layer structure, and there is no need to cut the blocking block above the pavement layer, so the removal process is simpler; the removed water retaining blocks can also be recycled and reused, which helps to improve material utilization and reduce costs.

[0009] Optionally, the fixing assembly includes a screw barrel, a screw rod and a block, the screw barrel is embedded in the embedded block, the screw rod is passed through the water retaining block, one end of the screw rod passing through the water retaining block is threadedly connected to the screw barrel, the block is fixedly connected to the end of the screw rod, and the block is used to abut against the side of the water retaining block away from the embedded block.

[0010] By adopting the above technical solution, the screw rod is tightened so that the block is pressed against the water retaining block, so that the water retaining block can be fixedly connected to the embedded block. When it needs to be disassembled, only the screw rod needs to be unscrewed, so the fixing and removal process is simple.

[0011] Optionally, the water retaining block is a trapezoidal block, and the inclined side walls on two adjacent water retaining blocks abut against each other.

[0012] By adopting the above technical solution, after tightening the screw, on the one hand, the water retaining block can be pressed against the embedded block, and on the other hand, the inclined side walls on two adjacent water retaining blocks can be pressed against each other. Therefore, tightening the screw can simultaneously enhance the sealing of the transverse gap and the longitudinal gap, thereby enhancing the water retaining property.

[0013] Optionally, a flexible pad is provided on the inclined side wall of the water retaining block.

[0014] The adoption of the above technical solution helps to enhance the water retaining effect at the gap between two adjacent water retaining blocks.

[0015] Optionally, a supporting mechanism is provided on one side of the embedded block, and the supporting mechanism includes a mounting plate, a fixing rod and a connecting assembly. The mounting plate is arranged on a side of the embedded block close to the water retaining block, the fixing rod is fixedly connected to the mounting plate, and one end of the fixing rod away from the mounting plate passes through the embedded block and is inserted into the ground. The connecting assembly is arranged between the mounting plate and the embedded block, and the connecting assembly is used to temporarily fix the embedded block to the mounting plate.

[0016] By adopting the above technical solution, the connecting component fixes the embedded block on the mounting plate, and then the bottom end of the fixing rod is inserted into the compacted soil layer to fix the mounting plate. The same operation is then performed to fix each mounting plate. It is only necessary to make each mounting plate flush with the previous mounting plate to make the embedded blocks under each mounting plate flush, thereby reducing the impact of the uneven soil layer on the installation effect of the anti-overflow base, which helps to improve the applicability of the anti-overflow base. In addition, the supporting mechanism can also support and fix the embedded block, thereby improving the stability of the embedded block during the subsequent pouring of the concrete pavement layer, and avoiding the pouring of the concrete pavement layer causing the position of the embedded block to shift, thereby affecting the water retaining effect.

[0017] Optionally, the connecting assembly includes a rotating rod, a blocking rod, a torsion spring and an embedded part, the rotating rod is rotatably connected to the mounting plate, the blocking rod is fixedly connected to the end of the rotating rod, the torsion spring is fixedly connected between the rotating rod and the mounting plate, the embedded part is embedded in the embedded block, and the embedded part is provided with a guide groove and an anti-slip groove for the blocking rod to slide into, one end of the guide groove is connected to the anti-slip groove, after the blocking rod slides into the anti-slip groove along the guide groove, the torsion spring causes the rotating rod and the blocking rod to rotate and reset, and makes the length direction of the blocking rod and the width direction of the guide groove staggered.

[0018] By adopting the above technical solution, the rotating rod is rotated, and the rotating rod can drive the blocking rod to rotate, and the blocking rod is rotated to a state flush with the guide groove, and then the mounting plate is slid to make the blocking rod slide into the anti-slip groove along the guide groove, and then the rotating rod is released, and the torsion spring can make the rotating rod and the blocking rod rotate and reset, so that the blocking rod is rotated to a state staggered with the guide groove, thereby preventing the blocking rod from sliding out of the guide groove, and completing the temporary connection between the mounting plate and the embedded block; the process of connecting and canceling the connection only requires rotating the rotating rod, so the operation is simple.

[0019] Optionally, the mounting plate and the embedded block abut against each other on their respective sides that are close to each other.

[0020] By adopting the above technical solution, after the embedded block and the mounting plate are temporarily fixed and connected, the mounting plate covers the top surface of the embedded block, and the mounting plate and the embedded block are in contact with each other, so that the mounting plate can shield and protect the top surface of the embedded block, avoiding concrete splashing onto the top wall of the embedded block when pouring the concrete pavement layer, helping to ensure the cleanliness of the top wall of the embedded block, and allowing the subsequent embedded block and the water retaining block to fit tightly, thereby ensuring the water retaining effect at the gap between the embedded block and the water retaining block.

[0021] Optionally, a flexible strip is fixedly provided on one side of the water retaining block close to the embedded block, and a receiving groove for receiving the flexible strip is provided on the embedded block.

[0022] By adopting the above technical solution, the water retaining effect at the gap between the embedded block and the water retaining block can be enhanced.

[0023] In a second aspect, the present application provides a construction method, which adopts the following technical solution: A construction method, using any of the above-mentioned assembled enclosure inner anti-overflow bases, comprises the following steps: a. Paste the anti-slip tape on the inside of the wooden formwork, pour concrete into the wooden formwork, and remove the wooden formwork after the concrete solidifies to form a blocking block; b. Place the blocking blocks on the compacted soil layer inside the enclosure, with the non-chisel-free grouting tape on the blocking blocks located at the bottom, and multiple blocking blocks spliced ​​together; c. Pour concrete with steel fiber added on the outside of the roughening-free stop strip to form a pavement layer. After the concrete solidifies, the blocking block can be fixed in the pavement layer.

[0024] By adopting the above technical solution, the blocking block and the concrete pavement layer are cast at one time, and the blocking block can be fixed after the concrete pavement layer solidifies, eliminating the tedious process of subsequent masonry, helping to simplify operations and shorten construction period.

[0025] In summary, this application includes the following beneficial technical effects: 1. The blocking blocks and concrete pavement are poured at one time, eliminating the tedious process of subsequent masonry, making the construction process simpler and helping to shorten the construction period.

[0026] 2. The two adjacent blocking blocks are matched with the positioning blocks and the positioning grooves, so they can play a positioning role during the installation of the blocking blocks and simplify the construction process; after the installation is completed, the water flow penetration path can be extended, thereby improving the water retaining effect.

[0027] 3. The separate setting of the blocking block makes it easier to remove the anti-overflow base later. The removed water retaining block can also be recycled, which helps to improve the utilization rate of materials.

[0028] 4. The supporting mechanism can support the embedded blocks so that the embedded blocks can be arranged neatly, and can maintain a good water-retaining effect after installation on uneven soil layers, and has stronger applicability; the supporting mechanism can fix the embedded blocks, thereby improving the stability of the embedded blocks during the pouring of the concrete pavement layer, which helps to ensure the water-retaining effect; in addition, the mounting plate in the supporting mechanism can also shield and protect the top surface of the embedded blocks to prevent concrete from splashing onto the top surface of the embedded blocks during the pouring of the concrete pavement layer, so that the subsequent embedded blocks and water-retaining blocks can fit tightly together, thereby ensuring the water-retaining effect.

DETAILED DESCRIPTION

[0031] The following combination Figure 1-Figure 9 This application is described in further detail.

[0032] Example 1 The present application embodiment discloses an assembled enclosure inner side anti-overflow base. Figure 1 , Figure 2 and Figure 3The anti-overflow base inside the assembled enclosure includes a plurality of blocking blocks 1 arranged side by side, and two adjacent blocking blocks 1 are in contact with each other. A positioning block 11 is fixedly connected to one side of the blocking block 1, and a positioning groove 12 adapted to the positioning block 11 is provided on the other side of the blocking block 1. The positioning block 11 on one blocking block 1 is snapped into the positioning groove 12 on the adjacent blocking block 1, thereby realizing the splicing between two adjacent blocking blocks 1, and improving the stability and waterproofness of the blocking blocks 1 after splicing. The blocking blocks 1 are prefabricated parts in the factory, so they are transported to the construction site after prefabrication. It is only necessary to arrange and fix the blocking blocks 1 on site, which is more time-saving and labor-saving than the masonry structure.

[0033] Reference Figure 1 and Figure 3 The bottom end of the blocking block 1 is fixedly provided with a non-burring grouting tape 2, which can create a rough surface effect at the bottom end of the blocking block 1, thereby increasing the contact area between the blocking block 1 and the concrete of the pavement layer 13, enhancing the bonding effect, and improving stability. When prefabricating the blocking block 1, the non-burring grouting tape 2 can be first bonded to the inner side of the wooden formwork, and then concrete is poured into the inner side of the wooden formwork. After the concrete solidifies, the formwork is removed, and the non-burring grouting tape 2 can be fixed to the bottom end of the blocking block 1, which is more convenient.

[0034] The implementation principle of Example 1 is as follows: first, the blocking blocks 1 are prefabricated in the factory, and then the blocking blocks 1 are transported to the construction site; the blocking blocks 1 are neatly arranged on the compacted soil layer 10 inside the enclosure 9, and the two adjacent blocking blocks 1 are matched through the positioning blocks 11 and the positioning grooves 12, so as to improve the stability and waterproofness of the blocking blocks 1 after they are placed. Then, concrete containing an appropriate amount of steel fibers is poured on the outside of the non-roughening grouting strip 2 to form a concrete pavement layer 13; after the concrete solidifies, the blocking blocks 1 can be fixed in the pavement layer 13.

[0035] Since the two adjacent blocking blocks 1 cooperate with each other through the positioning block 11 and the positioning groove 12, the water seepage path can be extended, so that the water inside the blocking block 1 is not easy to seep out through the gap between the two adjacent blocking blocks 1. The concrete covering the outside of the non-roughening grouting tape 2 contains a proper amount of steel fiber, which can enhance the tensile strength of the concrete and prevent the cracking of the joint caused by the vibration generated by the heavy vehicle running, thereby ensuring the water retaining effect.

[0036] This embodiment also discloses a construction method, comprising the following steps: Step a. Paste the anti-burring tape 2 on the inner side of the wooden formwork, then pour concrete into the wooden formwork, and after the concrete solidifies, a blocking block 1 provided with the anti-burring tape 2 is formed.

[0037] Step b. transport the blocking blocks 1 to the construction site, and then place the blocking blocks 1 on the compacted soil layer 10 inside the enclosure 9 , and multiple blocking blocks 1 are spliced ​​with each other through the cooperation of the positioning blocks 11 and the positioning grooves 12 .

[0038] Step c. pour concrete containing an appropriate amount of steel fiber on the outside of the roughening-free grouting strip 2, and after the concrete solidifies, a concrete pavement layer 13 can be formed on the compacted soil layer 10; the bottom end of the blocking block 1 is buried in the pavement layer 13, and water can be intercepted by the tightly spliced ​​blocking blocks 1.

[0039] Example 2 Reference Figure 4 The difference between this embodiment and embodiment 1 is that the blocking block 1 in this embodiment is a separate structure, and the blocking block 1 includes an embedded block 3 and a water retaining block 4. The roughening-free grout-stopping strip 2 is fixedly arranged on the outside of the embedded block 3, the water retaining block 4 is arranged on the top of the embedded block 3, and a fixing component 5 is arranged between the water retaining block 4 and the embedded block 3. Since the blocking block 1 is a separate structure, when the anti-overflow base needs to be removed later, the embedded block 3 can be left in the pavement layer 13, and only the water retaining block 4 needs to be removed. The removal process is simple, and the removed water retaining block 4 can be recycled, thereby improving the utilization rate of materials.

[0040] Reference Figure 5 The fixing assembly 5 includes a screw barrel 51, a screw rod 52 and a stopper 53. The screw barrel 51 is embedded in the embedded block 3; a through hole 43 coaxially arranged with the screw barrel 51 is provided in the water retaining block 4, and the screw rod 52 is slidably penetrated in the through hole 43; one end of the screw rod 52 passing through the through hole 43 is threadedly connected to the screw barrel 51. The stopper 53 is fixedly connected to the end of the screw rod 52, and the stopper 53 is pressed against the side of the water retaining block 4 away from the embedded block 3, so that the embedded block 3 and the water retaining block 4 can be fixedly connected.

[0041] The water retaining block 4 is a trapezoidal block, and the inclined side walls of two adjacent water retaining blocks 4 abut against each other. Under the cooperation between the inclined side walls of the trapezoidal blocks, the tightened screw 52 can make the inclined side walls between the two adjacent water retaining blocks 4 abut against each other, thereby enhancing the tightness of the cooperation between the two adjacent water retaining blocks 4, which helps to ensure the water retaining effect. Furthermore, a flexible pad 41 is bonded to the inclined side wall of the water retaining block 4, and the flexible pad 41 is a rubber pad, so that the water retaining effect can be further enhanced.

[0042] In addition, refer to Figure 6 A flexible strip 42 is bonded to one side of the water retaining block 4 close to the embedded block 3, and the flexible strip 42 is a rubber strip; correspondingly, a receiving groove 31 is opened on the top wall of the embedded block 3, and the flexible strip 42 is pressed tightly in the receiving groove 31, thereby helping to enhance the water retaining effect at the joint between the water retaining block 4 and the embedded block 3.

[0043] Reference Figure 7 and Figure 8 In order to further improve the applicability of the anti-overflow base and make the above-mentioned separated anti-overflow base structure applicable to uneven roads, a support mechanism 6 is provided on one side of the embedded block 3. The support mechanism 6 includes a mounting plate 61, a fixing rod 62 and a connecting assembly 63. The mounting plate 61 is arranged on the top side of the embedded block 3, and the bottom wall of the mounting plate 61 can abut against the top wall of the embedded block 3. The fixing rod 62 is vertically fixedly connected to the bottom wall of the mounting plate 61, and two fixing rods 62 are provided, and are respectively located at both ends of the mounting plate 61. The end of the fixing rod 62 away from the mounting plate 61 is sharp, so it is convenient to insert the end of the fixing rod 62 into the compacted soil layer 10, thereby supporting the mounting plate 61. The embedded block 3 is provided with an avoidance hole 32 for the fixing rod 62 to pass through. The connecting assembly 63 is arranged between the mounting plate 61 and the embedded block 3, and is used to temporarily fix the embedded block 3 to the bottom wall of the mounting plate 61.

[0044] Reference Figure 8 and Fig. 9 , two groups of connection components 63 are provided, and are respectively located at the two ends of the mounting plate 61. The connection component 63 includes a rotating rod 631, a stopper rod 632, a torsion spring 633 and an embedded part 634. The rotating rod 631 penetrates the mounting plate 61, and the rotating rod 631 rotates around its own axis and is connected to the mounting plate 61; one end of the rotating rod 631 is fixedly connected to a rotating block 6311, and the other end of the rotating rod 631 is vertically fixedly connected to the stopper rod 632. The torsion spring 633 is connected between the rotating rod 631 and the mounting plate 61, and under normal conditions, the torsion spring 633 is in a non-twisted state. The embedded part 634 includes an embedded plate 6341 and an embedded disk 6342, and the embedded plate 6341 is fixedly connected to the embedded disk 6342; a guide groove 7 is provided on the embedded plate 6341, and the cross-section of the guide groove 7 is rectangular, and the guide groove 7 can allow the blocking rod 632 to slide into; an anti-slip groove 8 is provided in the embedded disk 6342, and the anti-slip groove 8 is a circular groove, and one side of the anti-slip groove 8 is connected to the guide groove 7.

[0045] When connecting, the mounting plate 61 is placed above the embedded block 3, and the length direction of the blocking rod 632 is perpendicular to the width direction of the guide groove 7. Then, the rotating block 6311 is held and the rotating rod 631 is rotated to rotate the blocking rod 632 to a state aligned with the guide groove 7; then, the mounting plate 61 is slid downward to slide the blocking rod 632 into the anti-slip groove 8 along the guide groove 7; then, the rotating block 6311 is released, and under the action of the torsion spring 633, the rotating rod 631 and the blocking rod 632 are reversely rotated and reset, so that the blocking rod 632 is restored to a state staggered with the guide groove 7. Therefore, the blocking rod 632 is restricted in the anti-slip groove 8 at this time, and the blocking rod 632 cannot slide out of the anti-slip groove 8, thereby realizing the temporary connection between the mounting plate 61 and the embedded block 3.

[0046] After the temporary connection between the mounting plate 61 and the embedded block 3 is completed, the fixing rod 62 on the mounting plate 61 passes through the avoidance hole 32 on the embedded block 3, and then one end of the fixing rod 62 passing through the avoidance hole 32 is inserted into the compacted soil layer 10, so that the mounting plate 61 and the embedded block 3 can be fixed in the compacted soil layer 10. Then, the mounting plate 61 and the embedded block 3 are fixed in the compacted soil layer 10 through the fixing rod 62 by the same operation. During the process, it is only necessary to keep each mounting plate 61 flush with the previous mounting plate 61, so that each embedded block 3 can be in a flush state, thereby reducing the impact of uneven road surface on the installation effect, helping to ensure the neat arrangement of the embedded blocks 3, thereby improving the tightness of the subsequent water retaining blocks 4 and ensuring the water retaining effect.

[0047] The implementation principle of Example 2 is as follows: when the compacted soil layer 10 is relatively uneven, each embedded block 3 can be temporarily fixed on a mounting plate 61. Then, the fixing rod 62 on a mounting plate 61 is inserted into the compacted soil layer 10 to complete the fixing of this mounting plate 61; then, the fixing rod 62 on the next mounting plate 61 is inserted into the compacted soil layer 10, and at the same time, this mounting plate 61 is flush with the previous mounting plate 61; then, the above operation is repeated, so that each mounting plate 61 is arranged neatly, so that the embedded blocks 3 under all mounting plates 61 can be arranged neatly. After all mounting plates 61 are fixed, concrete containing an appropriate amount of steel fiber can be poured on the outside of the embedded block 3, and the top of the concrete can be flush with the top of the embedded block 3 to form a concrete pavement layer 13; after the concrete pavement layer 13 solidifies, the embedded block 3 can be fixed in the concrete pavement layer 13.

[0048] At this time, the rotating block 6311 at the top of the rotating rod 631 on each mounting plate 61 is rotated again, so that the blocking rod 632 is rotated to a state aligned with the guide groove 7, and then the mounting plate 61 and the embedded block 3 are separated. After all the mounting plates 61 and the corresponding embedded blocks 3 are separated, the water retaining block 4 is placed on the top surface of the embedded block 3, and then the screw rod 52 is inserted and tightened, so that the water retaining block 4 can be fixedly connected to the top of the embedded block 3. The tightened screw rod 52 can not only fix the water retaining block 4 to the embedded block 3, but also make the inclined side walls on the two adjacent water retaining blocks 4 press against each other, thereby helping to enhance the water retaining property.

[0049] After the construction in the construction area is completed, when the overflow prevention base needs to be removed, the screw 52 can be unscrewed, and then the water retaining block 4 can be removed from the embedded block 3. The removed water retaining block 4 can be recycled and reused, thereby improving the utilization rate of materials.

[0050] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
