Especially with the improvement of project quality requirements, the linear shape and elevation of cast-in-place anti-collision guardrails are becoming more and more stringent. If the anti-collision guardrail is constructed simply by manual labor and cranes, the construction time will be long. If the cast-in-place anti-collision guardrail is to achieve high-quality and high-efficiency construction results, a set of template trolleys that are easy to install and disassemble and quick to construct are required. In view of the existing problems of the above-mentioned cast-in-place anti-collision guardrail construction, a cast-in-place anti-collision guardrail with a multifunctional template operating trolley and a construction method thereof are proposed.

Similarly, another group of upper trusses 1 and lower trusses 2 and support columns 3 form an integral frame, and connect the two groups of frames horizontally with steel sections to form a trolley frame. Subsequently, the support columns 3 are installed on the support bottom beam 7, and the wheels 8 are rotatably installed on both sides of the support bottom beam 7. The front and rear support bottom beams 7 are connected by double-piece steel sections to form a four-wheel drive walking structure. The first sliding device 11 and the second sliding device 12 are respectively installed on both sides of the main truss 4, the hydraulic lifting bracket 5 is installed on the first sliding device 11, and the hanging basket 6 is installed on the second sliding device 12.

[0037] The first sliding device 11 and the second sliding device 12 are both provided with rollers for rotation, and the rotation of the rollers is controlled by motors.

[0038] Step 2: Template Installation

[0039] The template is installed below the hydraulic lifting support 5, and the second suspension rod 16 and the hook 17 are arranged on the crossbeam 14, respectively connected with the template and the square lifting ring 18 to form an adjustable template device 9. Then the first sliding device 11 is started to move the template to the design position of the anti-collision guardrail with the steel bars tied. The template includes an outer template 20 and an inner template 21, and the second suspension rod 16 is started to rotate the outer template 20 and the inner template 21 to a certain angle, and the first suspension rod 13 is started to slowly lower the adjustable template device 9. Then the second suspension rod 16 is started again to rotate the outer template 20 and the inner template 21 back to their original positions, and at the same time, the top support device 10 is installed on the outside of the inner template 21, and the template elevation and line shape are adjusted by the top support device 10 and the hook 17.

[0040] Specifically, the hydraulic lifting support 5 includes a first hanger 13, an inclined rod 15, and a cross beam 14, wherein the cross beam 14 is made of double-piece steel, the inclined rod 15 is used to connect the cross beam 14 and the first hanger 13, and the first hanger 13 is a hydraulic rod. The equipment installed on the cross beam 14 is controlled to move up and down by the lifting and lowering of the first hanger 13 to complete the template installation, spray maintenance and anti-corrosion paint coating.

[0041] Specifically, when the adjustable formwork device 9 is installed, the second suspension rod 16 and the hook 17 are first installed on the crossbeam 14 of the hydraulic lifting bracket 5. The second suspension rod 16 is connected to the first lifting ear 19 installed on the outer formwork 20 and the inner formwork 21 as a hydraulic rod. The inner formwork 21 includes a first inner formwork 29 and a second inner formwork 30. The outer formwork 20 and the first inner formwork 29 are connected to the square lifting ring 18 at the top with a hinge 22. The first inner formwork 29 and the second inner formwork 30 are also rotatably connected by a hinge 22.

[0042] Preferably, the top support device 10 includes a top support rod 23, an adjustable diagonal support 25 and an adjustable cross support 26. A support 24 is installed on the support column 3. One end of the top support rod 23 is rotatably installed on the support 24, and the other end is rotatably connected to one end of the adjustable cross support 26.

One end of the adjustable diagonal support 25 is connected to the ear seat 27 on the first inner template 29, and the other end is connected to the ear seat 27 on the top support rod 23.

[0043] When adjusting the template elevation, the first suspension rod 13 is used to roughly adjust the template elevation, and then the suspension hook 17 is moved up and down for fine adjustment. When adjusting the template line shape, the template line shape is first roughly adjusted by the second suspension rod 16, and then the adjustable cross brace 26 and the adjustable diagonal brace 25 are telescoped to finely adjust the line shape of the inner template 21, and then locked with the expansion lock 28.

[0044] In one embodiment of the present solution, the adjustable horizontal brace 26 and the adjustable diagonal brace 25 are both in the form of threaded telescopic rods, and the overall length is adjusted by rotating the threaded portion, and the expansion lock 28 can be a tightening bolt.

[0045] It is worth noting that the top support device 10 and the hook 17 can not only fine-tune the line shape and elevation of the template, but also play a role in fixing the template.

[0046] Step 3: Template Fixing

[0047] Install the tension screw 31 at the bottom of the outer formwork 20 and the second inner formwork 30, then install the triangular bracket 32 ​​at the top of the outer formwork 20 and the first inner formwork 29, one end of the adjustable tie rod 33 is connected to the triangular bracket 32, and the other end is fixed to the bridge deck. Then remove the top support device 10, and at the same time, separate the second suspension rod 16 and the hook 17 from the first lifting ear 19 and the square lifting ring 18 respectively, move to the next construction section and repeat the above template installation and fixing steps to set up and fix the template at the designed position.

[0048] Step 4: Install the cutting device

[0049] After the formwork is erected, a release agent 37 is applied to one side surface of the steel plates 35 on both sides, and butter 38 is applied to both side surfaces of the sandwich steel plate 36. Then, the steel plates 35 on both sides and the sandwich steel plate 36 are installed in place along the notches 34 on the formwork, and then concrete is poured.

[0050] Step 5: Template removal

[0051] After the concrete reaches the demolding strength, operate the first sliding device 11 to move it to the top of the template, lower the hydraulic lifting bracket 5, and connect the second suspension rod 16 and the hook 17 to the first lifting ear 19 and the square lifting ring 18 respectively. Then remove the triangular bracket 32, the tension screw 31 and the adjustable tie rod 33, and then operate the second suspension rod 16 to open the outer template 20 and the inner template 21 to a certain angle, and at the same time lift the first suspension rod 13 until the bottom of the template is higher than the top of the anti-collision guardrail, and then start the first sliding device 11 to move the template to the inside of the trolley. After lowering the first suspension rod 13, remove the second suspension rod 16, the hook 17 and the template, and repeat this step to complete the template removal.

Then the first sliding device 11 is controlled to move above the anti-collision guardrail and slowly descend until the bottom of the C-shaped water pipe 45 is lower than the bottom of the anti-collision guardrail. Then the water pipe joint 47 is used to connect the C-shaped water pipe 45 and the L-shaped water pipe 46. At the same time, the C-shaped water pipe 45 is installed on the hydraulic lifting bracket 5 by a clamp, and the connecting rod 49 and the pulley 50 are connected to complete the installation and fixation of the water pipe, and the water tank car 40 is connected at the same time.

[0054] Specifically, the automatic sprinkler device 39 includes a C-shaped water pipe 45, an L-shaped water pipe 46, a connecting rod 49, a pulley 50 and a water pipe joint 47.

[0056] Furthermore, a hook 17 is installed at the end of the crossbeam 14 outside the anti-collision guardrail for hanging a C-shaped water pipe 45.

[0057] Step 7: Spray maintenance

[0058] After the automatic spraying device 39 is installed, the water pump is started to spray evenly on the anti-collision guardrail through the spray head 48 on the water pipe. At the same time, the walking system of the multifunctional template operation trolley and the water tank car 40 is started, and the same speed is maintained to move forward to complete the spraying work of the anti-collision guardrail.

[0059] Step 8: Dismantle the automatic sprinkler system

[0060] After the maintenance is completed, the connection between the water pipe and the water tank car 40 is removed, and then the connection between the water pipe joint 47 and the C-type water pipe 45 is removed. At the same time, the third suspension rod 43 above the C-type water pipe 45 is removed, and the hook 17 is installed on the second lifting ear 42. Then, the connecting rod 49 and the pulley 50 at the bottom end 51 of the C-type water pipe 45 are removed. Then, the hydraulic lifting bracket 5 is started to raise the automatic spraying device 39. After the bottom of the water pipe is higher than the anti-collision guardrail, the first sliding device 11 is opened to move the automatic spraying device 39 to the inside of the trolley. After lowering the first suspension rod 13, the third suspension rod 43, the clamp and the water pipe are removed.
