Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a slope surface construction method. Background Art

[0002] Slope generally refers to the landform area where the ground line and the horizontal plane form a certain angle in the original landform. Slope surface usually exists in facilities such as winding mountain roads, bridge decks, swimming pool walls, dams, etc. The side wall of the swimming pool is usually set as a slope structure. However, when the slope surface is constructed, due to the large slope, the concrete will slide down the slope surface, resulting in the slope not meeting the preset requirements, and the pouring quality is difficult to control. Therefore, low slump concrete is required; and it is difficult for workers to vibrate the concrete, resulting in quality defects such as honeycombs, rough surfaces, and voids on the slope surface, and even unqualified structural strength, which can easily cause structural surface leakage or safety hazards. Summary of the invention

[0003] In order to prevent and improve the strength of the slope and reduce cavities, the present application provides a slope construction method.

[0004] This application provides a slope surface construction method, which adopts the following technical solution:

[0005] The slope surface construction method comprises the following steps:

[0006] S1, leveling the base layer, making the base layer into a flat slope;

[0007] S2, set up mesh steel structure: arrange the steel bars in the horizontal and vertical directions and set them on the base;

[0008] S3, laying the template: the template includes two side plates, a panel and a number of supporting nails. The panel is arranged parallel to the base layer, the side plates are arranged at the left and right ends of the panel, the tips of the supporting nails are pushed into the base layer, and the panel is provided with nail holes for accommodating the supporting nails; at least one vibration motor is arranged on the panel and the two side plates; the template is located at the bottom end of the slope of the base layer, and the bottom of the casting cavity between the template and the base layer is closed by the ground;

[0009] S4, pouring: pour concrete from the slope into the pouring cavity of the panel and the base, using concrete with a slump of 120-200mm;

[0010] S5, vibration compaction: after the pouring cavity is filled, all vibration motors are turned on to compact the concrete in the pouring cavity, and after the cavity at the top of the pouring cavity is formed, concrete is poured in to fill it, and then the vibration motors are turned off;

[0011] S6, demoulding: After standing for 3-5 days, turn on all vibration motors to vibrate the solidified concrete slope and formwork, and remove the panel, side panels, and support nails;

[0012] S7, continue pouring: continue to lay the removed formwork on the top of the base layer, at this time, the top of the solidified concrete slope is located at the bottom of the pouring cavity formed by the new round of formwork and the base layer, and repeat steps S4-S6 until the entire base layer is poured;

[0013] S8, maintenance: water the concrete slope after demoulding to prevent cracking of the concrete slope;

[0014] S9, brick paving: including precast concrete brick body, the precast concrete brick body includes a brick plate and connecting nails integrally formed at the bottom of the brick plate; nail pits are formed after the supporting nails are separated from the base layer and the precast parts. When the precast concrete brick body is laid, cement slurry is poured into the nail pits, and then the cement slurry is coated on the concrete slope. The brick plate is laid on the concrete slope, and the connecting nails are inserted into the nail pits.

[0015] By adopting the above technical solution, the mesh steel structure improves the overall relevance of the concrete slope. The template is used to enclose the casting cavity between the base and the panel, and then the concrete is poured in. There is no need to use concrete with low slump. Concrete with a slump of 120-200mm can be used to reduce the effect of adding water-reducing agents such as admixtures that increase slump on the strength of concrete, thereby reducing the concrete solidification voids and maintaining a high strength. In addition, a vibration motor is set on the side panel to vibrate the concrete poured into the cylinder during pouring, reduce bubbles and gaps, and make the concrete high in strength after curing; at the same time, it vibrates during demoulding to facilitate demoulding of the template.

[0016] The supporting nails prevent the panel from being scratched during vibration. After the precast concrete bricks are laid, the connecting nails are driven into the nail holes left by the support nails. This allows the connecting nails to connect the brick layer, concrete layer and base layer. This improves the correlation between the slope and makes it less likely for stratified landslides to occur.

[0017] In the slope surface construction method of the present application, the construction method is simple, there is no need to use low-slump concrete, and the concrete can be compacted, the density of the concrete is improved, the slope surface is strong and not easy to leak.

[0018] Optionally, the support nails are driven into the base layer by 10-30 cm.

[0019] By adopting the above technical solution, at this depth, the depth of the nail pit is appropriate, and the connecting nails can be conveniently and stably connected to the base layer.

[0020] Optionally, the driving angle of the support nails is perpendicular to the base layer.

[0021] By adopting the above technical solution, the production of precast concrete bricks is facilitated, and the fixing depth of the connecting nails can be deeper, so that the connection between the connecting nails and the base layer, the concrete layer and the brick layer is more stable.

[0022] Optionally, the supporting nails are nailed into the front surface coating.

[0023] By adopting the above technical solution, after lamination, the support nails and concrete are separated by the membrane layer, and the support nails can be demoulded without large vibration.

[0024] Optionally, a vibration damping ring is provided in the nail hole.

[0025] By adopting the above technical solution, in order to prevent concrete from leaking out of the nail hole, the inner wall of the nail hole and the outer wall of the supporting nail are more closely fitted. When the vibration damping ring vibrates the panel, it generates flexible vibration on the supporting nail, making the supporting nail less likely to be damaged. In addition, there is a certain vibration sense, which helps to demold the supporting nail.

[0026] Optionally, a positioning piece is provided at one end of the supporting nail away from the tip, and the outer diameter of the positioning piece is larger than the inner diameter of the nail hole.

[0027] By adopting the above technical solution, the positioning piece is used to determine the length of the support nail nailed into the panel, and then the depth of the nail nailed into the base layer is determined according to the height of the casting cavity, which plays the role of positioning the height. When the bottom of the positioning piece is close to the panel, the support nail insertion height meets the requirements.

[0028] Optionally, the supporting nail includes an integrally formed threaded section and a rod section, the tip is arranged at an end of the rod section away from the threaded section, and the positioning member is provided with a threaded hole for threaded connection of the threaded section.

[0029] By adopting the above technical solution, the positioning piece is rotated to facilitate the adjustment of the height of the positioning piece on the threaded section, thereby facilitating the adjustment of the depth of the nail into the base layer.

[0030] Optionally, in S4, before pouring, a supporting device is used to abut the outer side surface of the panel to keep the panel flat.

[0031] By adopting the above technical solution, the panels are abutted, so that the stress of the concrete on the panels is not likely to lift up the panels.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] In the slope surface construction method of the present application, the construction method is simple, there is no need to use low-slump concrete, and the concrete can be vibrated to improve the density of the concrete, so that the slope surface has high strength and is not easy to leak;

[0034] The nailing angle of the support nail is perpendicular to the base layer, which is convenient for the production of precast concrete bricks and can make the depth of the connection nail deeper, making the connection between the base layer, concrete layer and brick layer more stable;

[0035] When the vibration-damping ring makes the panel vibrate, it generates flexible vibration on the supporting nails, making the supporting nails less likely to be damaged. In addition, there is a certain vibration feeling, which helps the supporting nails to be demoulded. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-4 This application is described in further detail.

[0042] The present application embodiment discloses a slope surface construction method. Figure 1 and Figure 2 , the slope surface construction method includes the following steps:

[0043] S1, level the base 1, remove stones, fill in pits, use a compactor to compact the base 1, and level the base 1 into a slope of 10-40 degrees. The swimming pool usually uses a slope of 20-30 degrees.

[0044] S2, set up a mesh steel structure (not shown in the figure): arrange the steel bars in the horizontal and vertical directions on the base layer 1, and partially bury the steel bars in the base layer 1 to improve the connection strength between the mesh steel structure and the base layer 1, so as to improve the overall relevance of the concrete after pouring.

[0045] S3, laying the formwork 2: the formwork 2 includes two side panels 21, a panel 22 and a plurality of support nails 23. The panel 22 is arranged parallel to the base 1, the side panels 21 are fixed to the left and right ends of the panel 22, and the side panels 21 support the two ends of the panel 22 suspended in the base 1, so that a casting cavity is formed between the base 1 and the panel 22. The ends where the panel 22 and the side panels 21 are connected are arranged with splicing blocks 24 at intervals, and the ends of the side panels 21 and the panel 22 are meshed and connected through the splicing blocks 24.

[0046] The panel 22 is provided with nail holes 3 in a matrix to accommodate the support nails 23. A vibration damping ring 4 is fixed in the nail hole 3. The vibration damping ring 4 is a plastic ring, and the inner wall of the vibration damping ring 4 fits the outer wall of the support nail 23. The tip of the support nail 23 is pushed into the base layer 1, and the support nail is nailed into the base layer 10-30cm, and the nailing angle of the support nail 23 is perpendicular to the base layer 1, and the position of the support nail 23 avoids the mesh steel structure.

[0047] The support nail 23 includes an integrally formed threaded section 231 and a rod section 232, the tip of which is disposed at the end of the rod section 232 away from the threaded section 231. The positioning member 5 is provided with a threaded hole for the threaded section 231 to be threadedly connected, and the depth of the nailing is changed by rotating the positioning member 5. The outer diameter of the positioning member 5 is larger than the inner diameter of the nail hole 3, so that the positioning member 5 will not enter the nail hole 3. When the panel 22 is demoulded, the support nail 23 can be demoulded together due to the limitation of the positioning member 5.

[0048] At least one vibration motor 6 is provided on the panel 22 and the two side panels 21, wherein one vibration motor 6 is provided on each of the two side panels 21, and a plurality of vibration motors 6 are evenly distributed and installed on the panel 22. The pouring starts from the bottom end of the slope, the template 2 is located at the bottom end of the slope of the base 1, and the bottom of the pouring cavity between the template 2 and the base 1 is closed by the ground.

[0049] S4, pouring: Before pouring, use a supporting device to abut the outer side of the panel 22 to keep the panel 22 flat. In the embodiment, an excavator is used as the supporting device, and the bucket of the excavator abuts the center of the panel 22 to keep the panel 22 flat. Then pour concrete from the slope into the pouring cavity of the panel 22 and the base layer 1, and use concrete with a slump of 120-200mm for pouring. In the embodiment, concrete with a slump of 150-200mm is used, which has good fluidity and is convenient for flowing into the bottom of the panel 22.

[0050] S5, compaction: after the casting cavity is filled, keep the bucket against the panel 22, then turn on all the vibration motors 6 to compact the concrete in the casting cavity. After the first compaction, turn off the vibration motor 6. For the cavity generated at the top of the casting cavity, continue to pour concrete to fill the cavity and turn on the vibration motor 6 to compact it. Then turn off the vibration motor 6. Repeat this step until no obvious cavity appears and complete the concrete compaction step.

[0051] S6, demoulding: after standing for 3-5 days, turn on all vibration motors 6, vibrate for 30-60 seconds, then turn off the vibration motors 6, and vibrate to separate the solidified concrete slope 9 and the formwork 2, first remove the support nails 23, and then remove the panel 22 and the side panel 21.

[0052] S7, continue pouring: continue to lay the removed formwork 2 on top of the base layer 1. At this time, the top of the solidified concrete slope 9 is located at the bottom of the pouring cavity formed by the new round of formwork 2 and the base layer 1, so that the bottom of the pouring cavity is closed, and then repeat steps S4-S6 until the entire base layer 1 is poured.

[0053] S8, curing: watering and curing the concrete slope 9 after demoulding to prevent the concrete slope 9 from cracking.

[0054] S9, brick laying: refer to Figure 2 , Figure 3 and Figure 4 , including a precast concrete brick body 7, the precast concrete brick body 7 includes a brick plate 71 and a connecting nail 72 integrally formed at the bottom of the brick plate 71; the supporting nail 23 is separated from the base 1 and the precast part to form a nail pit 8. When the precast concrete brick body 7 is laid, cement slurry is poured into the nail pit 8, and then the cement slurry is coated on the concrete slope 9. The brick plate 71 is laid on the concrete slope 9, and the connecting nail 72 is inserted into the nail pit 8. After drying for 7-10 days, the slope surface construction is completed.

[0055] The implementation principle of a slope surface construction method of the present application embodiment is as follows: the setting of the mesh steel structure makes the cast concrete slope 9 integral. A concrete cavity is formed between the template 2, the panel 22 and the base 1. Due to the setting of the slope, after vibration, the concrete will first fill the bottom of the slope by gravity, and the concrete after vibration is more compact and has high strength. Since the concrete needs to flow from the top of the casting cavity to the bottom, concrete with a higher slump is selected. The concrete with a high slump has higher strength, thereby improving the strength of the slope. When demolding, the vibration motor 6 vibrates to separate the concrete slope 9 from the template 2, making demolding convenient. In addition, a support nail 23 is set, and the support nail 23 makes it difficult for the template 2 to slide down the slope, and a nail pit 8 is formed at the same time. After the concrete brick body 7 is installed later, the connecting nail 72 is inserted into the nail pit 8, so that the brick body 7, the concrete slope 9 and the base 1 are strongly associated, so that the overall strength of the slope surface is good, the density is good, and the anti-slip performance is good.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
