Description

Technical Field

[0001] This invention relates to the field of road construction technology, specifically to a construction process for a 35-meter-wide road. Background Technology

[0002] In the current process of concrete road construction, especially the construction of ultra-wide concrete roads, the pouring work cannot be completed in one go. Therefore, the overall stability of the concrete surface layer cannot be guaranteed due to the influence of the physical properties of concrete. So, it is particularly important to design a construction process for 35-meter ultra-wide roads in order to solve the above problems. Summary of the Invention

[0003] To address the aforementioned problems, this invention presents a construction process for an ultra-wide 35-meter road. By rationally dividing the construction into blocks and constructing them sequentially, the problem of being unable to pour the concrete in one go and being affected by the physical properties of the concrete is solved, thus ensuring the overall stability of the concrete surface layer.

[0004] To solve the above-mentioned technical problems, the present invention provides a construction process for a 35-meter ultra-wide road, characterized by the following steps:

[0005] S1: Construction preparation: Divide the 35-meter-wide road into sections, carry out roadbed construction according to sections, and lay out the roadside stakes and centerline according to the construction design drawings;

[0006] S2: Formwork erection: After the roadbed construction of each section is completed, the formwork is placed, and steel reinforcement is set on the outside of the formwork;

[0007] S3: Binding and placement of concrete reinforcing mesh: The HRB400 grade C12 steel bars are processed using an integrated steel bar processing device. The processed steel bars are bound according to size specifications to form a concrete reinforcing mesh, which is then placed in each panel with the formwork installed.

[0008] S4: Concrete pouring: Concrete is poured into the slab containing the concrete reinforcement mesh using a concrete pouring device;

[0009] S5: Curing: Curing can begin within 12 hours of the completion of the concrete slab construction. Use a plastic film watering method, watering the surface 2-3 times a day and night, keeping it moist for no less than 7 days.

[0010] Further: The template in step S2 is a steel template with a height of 0.3m and a length of 6m. A steel bar support is set every 1m on the outside of the template. Adjacent templates are tightly connected by a flat-head locking method. The template is coated with a release agent before each concrete pour.

[0011] Furthermore: In step S3, the concrete steel mesh is arranged in a double layer, and the double-layer mesh is connected by a stirrup support. The steel bars in the stirrup support are 100cm long and are arranged in a 600*600mm staggered pattern. The horizontal steel bar spacing in each mesh is 60cm and the vertical steel bar spacing is 30cm. The vertical steel bars are placed above the horizontal steel bars. The lap length of the vertical steel bars is 15cm, and single-sided lap welding is used. The lap rate is not greater than 50%.

[0012] Furthermore: After all slabs are poured, joint construction is required in the concrete pouring process described in S4. This joint construction is divided into longitudinal joint construction and transverse joint construction. Due to the segmented construction method, longitudinal construction joints exist between adjacent slabs. During the concrete pouring process, partitions need to be installed at the end of each day or during temporary interruptions of 30-45 minutes. These partitions will create transverse construction joints. For multi-lane roads, transverse construction joints should be avoided on the same cross-section. The longitudinal construction joints are flat joints, with the upper groove cut using a joint cutter. The groove is 0.5cm wide and 3cm deep, and should be filled with sealant. Sealing is performed after curing, using 70# petroleum asphalt to prevent water seepage and the accumulation of hard debris. The transverse construction joints are dummy joints, formed when the concrete strength reaches 8MPa. When cutting joints, generally, when the temperature is 25-30 degrees Celsius, cutting joints should be done 8-10 hours after concrete pouring; when the temperature is 20-25 degrees Celsius, cutting joints should be done 10-20 hours after concrete pouring. In any case, the cutting time should not exceed 24 hours. To reduce early cracking, the "skip-section method" can be used for cutting joints, that is, cut a joint every other slab, and then saw each slab one by one. The width of the transverse construction joint is 0.5cm and the depth is 5cm. The groove is filled with joint filler material. The joint filling is carried out after curing, and the material used is 70# petroleum asphalt.

[0013] Furthermore: the concrete pouring in step S4 specifically includes the following steps:

[0014] A1: Concrete placement: First, C25 concrete is placed using a concrete pumping device, and then 10cm of C40 concrete is placed before the initial setting of 20cm of C25 concrete.

[0015] A2: Concrete Vibration and Leveling: (1) After the 20cm C25 concrete mix is ​​laid out, the first vibration operation is started. An immersion vibrator is used for vibration. When the vibrator is inserted intermittently, the distance moved each time should not exceed 1.5 times the effective radius of the vibrator and should not be greater than 50cm. The vibration time should be 15~30s. The compaction is achieved when the coarse aggregate in the mix stops settling, no more air bubbles appear on the surface, and cement slurry rises. Note that over-vibration should be avoided. The immersion vibrator should move slowly and continuously at a uniform speed; (2) After the first 20cm C25 layer is vibrated, a 10cm C40 mix is ​​laid out; (3) After the second mix is ​​laid out, a vibrating beam is used for leveling;

[0016] A3: Fine-level finish: After the vibratory beam has basically leveled the road surface, the thickness and water-cement ratio of the surface mortar along the longitudinal direction have reached uniformity, but it may not be uniform along the transverse direction. A 3-5m scraper should be used for finishing. After the surface water has evaporated, a finishing machine should be used to finish the surface.

[0032] This invention provides a construction process for a 35-meter ultra-wide road, comprising the following steps:

[0033] S1: Construction preparation: Divide the 35-meter-wide road into sections, carry out roadbed construction according to sections, and lay out the roadside stakes and centerline according to the construction design drawings;

[0034] S2: Formwork erection: After the roadbed construction of each section is completed, the formwork is placed, and steel reinforcement is set on the outside of the formwork;

[0035] S3: Binding and placement of concrete reinforcing mesh: The HRB400 grade C12 steel bars are processed using an integrated steel bar processing device. The processed steel bars are bound according to size specifications to form a concrete reinforcing mesh, which is then placed in each panel with the formwork installed.

[0036] S4: Concrete pouring: Concrete is poured into the slab containing the concrete reinforcement mesh using a concrete pouring device;

[0037] S5: Curing: Curing can begin within 12 hours of the completion of the concrete slab construction. Use a plastic film watering method, watering the surface 2-3 times a day and night, keeping it moist for no less than 7 days.

[0038] The above-mentioned step S1 divides the roadbed into eight sections from left to right. The first, second, third, sixth, seventh, and eighth sections on both sides are 4.5m long, while the fourth and fifth sections in the middle are 4m long. The roadbed construction by section in step S1 specifically means that the third section is constructed on the first day, the first section on the second day, the second section on the third day, the sixth section on the fourth day, the eighth section on the fifth day, the seventh section on the sixth day, the fifth section on the seventh day, and the fourth section on the eighth day. The fourth and fifth sections are used as the concrete pump station positions. After the third section reaches a certain strength, the concrete pump station is placed on it.

[0039] The template used in step S2 above is a steel template with a height of 0.3m and a length of 6m. A steel bar support is set every 1m on the outside of the template. Adjacent templates are tightly connected by a flat-head locking method. A release agent is applied to the template before each concrete pour.

[0040] The concrete reinforcement mesh in step S3 above is arranged in a double layer. The double-layer mesh is connected by a stirrup support. The length of the steel bars in the stirrup support is 100cm. They are arranged in a 600*600mm quincunx pattern. The spacing between the transverse steel bars in each mesh is 60cm and the spacing between the longitudinal steel bars is 30cm. The longitudinal steel bars are placed above the transverse steel bars. The lap length of the longitudinal steel bars is 15cm. Single-sided lap welding is used, and the lap rate is not greater than 50%.

[0041] After all slabs are poured, joint construction is required in the concrete pouring process described in S4 above. This joint construction includes longitudinal and transverse joint construction. Because the road surface is constructed in sections, longitudinal construction joints exist between adjacent slabs. During the concrete pouring process, partitions need to be installed at the end of each day or during temporary interruptions of 30-45 minutes. These partitions will create transverse construction joints. For multi-lane roads, transverse construction joints should be avoided on the same cross-section. The longitudinal construction joints are flat joints, with the upper groove cut using a joint cutter. The groove is 0.5cm wide and 3cm deep, and should be filled with sealant. Sealing should be done after curing, using 70# petroleum asphalt to prevent water seepage and the accumulation of hard debris. The transverse construction joints are dummy joints. When the concrete strength reaches 8MPa... When cutting joints, generally, when the temperature is 25-30 degrees Celsius, cutting joints should be done 8-10 hours after concrete pouring; when the temperature is 20-25 degrees Celsius, cutting joints should be done 10-20 hours after concrete pouring. In any case, the cutting time should not exceed 24 hours. To reduce early cracking, the "skip-section method" can be used for cutting joints, that is, cut a joint every other slab, and then saw each slab one by one. The width of the transverse construction joint is 0.5cm and the depth is 5cm. The groove is filled with joint filler material. The joint filling is carried out after curing, and the material used is 70# petroleum asphalt.

[0042] The concrete pouring in step S4 above is specifically divided into the following steps:

[0043] A1: Concrete placement: First, C25 concrete is placed using a concrete pumping device, and then 10cm of C40 concrete is placed before the initial setting of 20cm of C25 concrete.

[0044] A2: Concrete Vibration and Leveling: (1) After the 20cm C25 concrete mix is ​​laid out, the first vibration operation is started. An immersion vibrator is used for vibration. When the vibrator is inserted intermittently, the distance moved each time should not exceed 1.5 times the effective radius of the vibrator and should not be greater than 50cm. The vibration time should be 15~30s. The compaction is achieved when the coarse aggregate in the mix stops settling, no more air bubbles appear on the surface, and cement slurry rises. Note that over-vibration should be avoided. The immersion vibrator should move slowly and continuously at a uniform speed; (2) After the first 20cm C25 layer is vibrated, a 10cm C40 mix is ​​laid out; (3) After the second mix is ​​laid out, a vibrating beam is used for leveling;

[0045] A3: Fine-level finish: After the vibratory beam has basically leveled the road surface, the thickness and water-cement ratio of the surface mortar along the longitudinal direction have reached uniformity, but it may not be uniform along the transverse direction. A 3-5m scraper should be used for finishing. After the surface water has evaporated, a finishing machine should be used to finish the surface.

[0046] During the curing period of the concrete slab, a designated person shall supervise the process and prohibit passage. When the concrete reaches 40% strength (approximately 4-7 days), pedestrian access is permitted. Twelve days after pouring, when the concrete strength reaches 70%, small cars and light vehicles are allowed to pass. Normal use is permitted after 28 days of pouring, when the concrete strength reaches 100%. After the curing period, the covering material shall be removed, leaving no trace on the slab surface. Formwork removal should be carried out by a carpenter, taking care not to damage the edges and corners of the concrete, and maintaining the integrity of the formwork as much as possible, especially at the joints, which should be removed by a designated person.

[0047] The integrated steel bar processing device in step S4 above is as follows: Figure 1 , Figure 2 and Figure 4As shown, it specifically includes a base plate, a worktable 1, a turntable 2, a positioning block 3, a support column 4, an extrusion roller 9, a guide sleeve 13, and a cutting wheel 18. The worktable is fixed above the base plate by the column. The support column and the turntable are concentrically arranged. The support column is fixedly connected to the worktable. The turntable is embedded in the top of the worktable and can rotate around the support column. The upper end of the worktable is flush with the upper end of the turntable. The positioning block and the extrusion roller are located on one side of the support column. The positioning block is connected to the U-shaped guide frame 5 by a guide block 6 integrated with it. The U-shaped guide frame has a threaded through hole, and the threaded through hole connects to... An adjusting bolt 7 extends into the U-shaped guide frame along a threaded through hole and connects to the guide block. One end of the adjusting bolt extending into the U-shaped guide frame is movably connected to the guide block. The extrusion roller is rotatably connected to the mounting frame 8. The extrusion roller extends out of the mounting frame and contacts the reinforcing bar. The mounting frame is fixed on the turntable and connected to the adjustable lever arm 10. A transverse through groove is provided on the worktable plate on the right side of the turntable. A baffle 15 is movably connected in the transverse through groove. The baffle is connected to the first lifting electric cylinder, which is connected to the first translation electric cylinder. The baffle can slide along the transverse through groove under the drive of the first translation electric cylinder. The cutting wheel can extend from the transverse through-slot. A length marker 16 is provided on one side of the transverse through-slot. Two guide sleeves 13 are provided on the worktable plate on the left side of the turntable. The two guide sleeves and the transverse through-slot are arranged in a straight line, with a gap between the two guide sleeves. A longitudinal through-slot is formed on the worktable plate between the two guide sleeves. The cutting wheel is movably connected within the longitudinal through-slot. A downward-pressing electric cylinder 14 is installed on the top of each guide sleeve. The output shaft of the downward-pressing electric cylinder extends into the guide sleeve and connects to the arc-shaped clamping plate. Two drive rollers 11 are arranged opposite each other on the left end of the worktable plate. Each drive roller is connected to the worktable plate via a roller connecting bracket 12. The drive rollers are connected to the rollers mounted on the roller... The rollers on the connecting frame are connected to the drive motor; the adjustable lever arm includes a connecting arm 10-1, an adjusting arm 10-2, a locking pin 10-3, and a spring. One end of the connecting arm is fixedly connected to the mounting frame. One end of the adjusting arm has a guide groove that matches the connecting arm. The other end of the connecting arm extends into the guide groove of the adjusting arm. Connecting holes are provided on the front and rear outer walls of the connecting arm end that extends into the guide groove. A locking pin is connected to the connecting hole by a spring. Several locking holes are provided on the upper and lower side walls of the adjusting arm at positions relative to the connecting holes. Several locking holes on the same side are arranged in a straight line. The locking pin extends out of the adjusting arm along the locking hole under the action of the spring. One end of the locking pin extending out of the adjusting arm is spherical.

[0048] When the reinforcing bar needs processing, it is transported to the right by two drive rollers, passing between the support column and the extrusion roller. The drive rollers stop transporting the reinforcing bar, and the adjustable lever arm is moved to bend it. After bending, the baffle is adjusted and extended, and the drive rollers are restarted to continue transporting the reinforcing bar to the right. The reinforcing bar stops under the obstruction of the baffle. At this point, the drive rollers stop transporting the reinforcing bar, and the downward-pressing electric cylinder is activated to clamp the reinforcing bar using an arc-shaped clamping plate. The cutting wheel then cuts the reinforcing bar. After cutting, the baffle retracts back into the transverse slot, and the cut and bent reinforcing bar is removed. This invention, using the above structure, can not only bend reinforcing bars but also perform precise length cutting, greatly increasing its practicality.

[0049] like Figure 3 The cutting wheel shown is installed in the fixed frame 21 and connected to the cutting wheel drive motor 22. The cutting wheel extends out of the worktable along the longitudinal through groove. The fixed frame is fixed on the support plate 19.

Each support column has a mounting hole at its bottom, and a third lifting cylinder is installed within the mounting hole. The output shaft of the third lifting cylinder extends out of the mounting hole and connects to the support leg.

4. The construction process for a 35-meter ultra-wide road according to claim 1, characterized in that: After all slabs are poured, joint construction is required in the S4 section of the concrete pouring process. This joint construction includes longitudinal and transverse joint construction. Because the road surface is constructed in sections, longitudinal construction joints exist between adjacent slabs. During the concrete pouring process, partitions need to be installed at the end of each day or during temporary interruptions of 30-45 minutes. These partitions will create transverse construction joints. For multi-lane roads, transverse construction joints should be avoided on the same cross-section. The longitudinal construction joints are flat joints, with the upper groove cut using a joint cutter. The groove is 0.5cm wide and 3cm deep, and should be filled with sealant. Sealing is done after curing, using 70# petroleum asphalt to prevent water seepage and the accumulation of hard debris. The transverse construction joints are dummy joints, formed when the concrete strength reaches 8MPa. When cutting joints, generally, when the temperature is 25-30 degrees Celsius, cutting joints should be done 8-10 hours after concrete pouring; when the temperature is 20-25 degrees Celsius, cutting joints should be done 10-20 hours after concrete pouring. In any case, the cutting time should not exceed 24 hours. To reduce early cracking, the "skip-section method" can be used for cutting joints, that is, cut a joint every other slab, and then saw each slab one by one. The width of the transverse construction joint is 0.5cm and the depth is 5cm. The groove is filled with joint filler. The joint filling is carried out after curing, and the material used is 70# petroleum asphalt.

5. The construction process for a 35-meter ultra-wide road according to claim 1, characterized in that: The concrete pouring in step S4 is specifically divided into the following steps: A1: Concrete placement: First, C25 concrete is placed using a concrete pumping device, and then 10cm of C40 concrete is placed before the initial setting of 20cm of C25 concrete. A2: Concrete vibration and leveling: (1) After the 20cm C25 concrete mix is ​​laid out, the first vibration operation is started. An immersion vibrator is used for vibration. When the vibrator is inserted intermittently, the distance moved each time should not exceed 1.5 times the effective radius of the vibrator and should not be greater than 50cm. The vibration time should be 15~30s. The compaction is judged by the coarse aggregate in the mix stopping settling, no more air bubbles appearing on the surface, and cement slurry rising. Note that over-vibration should be avoided. The immersion vibrator should move slowly and continuously at a uniform speed. (2) After the first 20cm C25 is vibrated, a 10cm C40 mix is ​​laid out. (3) After the second mix is ​​laid out, a vibrating beam is used for leveling. A3: Fine-level finish: After the vibratory beam has basically leveled the road surface, the thickness and water-cement ratio of the surface mortar along the longitudinal direction have reached uniformity, but it may not be uniform along the transverse direction. A 3-5m scraper should be used for finishing. After the surface water has evaporated, a finishing machine should be used to finish the surface.
