[0066] Step 14: Watering and curing: The concrete cast crash barrier is subjected to one-week watering and curing to complete the construction.

[0067] It should be noted that, in this embodiment,

[0068] During construction preparation: Develop a construction plan, including detailed engineering processes, construction steps, equipment and materials to be used. Ensure that the plan complies with building regulations and standards and has been approved. All personnel involved in the construction should receive relevant training, including construction safety, equipment operation and emergency response. Ensure that they have the necessary skills and knowledge. Provide and ensure that construction personnel wear appropriate personal protective equipment, such as hard hats, gloves, etc. Equipped with first aid and safety equipment such as on-site first aid kits and fire extinguishers. Set up fences or signs around the construction site to ensure that only authorized personnel can enter the construction area. Develop and implement a construction site traffic management plan to ensure smooth and safe traffic around. Prepare and check the required construction materials according to the design plan to ensure that their quality and quantity meet the requirements. Conduct a comprehensive inspection of the mechanical equipment required for construction to ensure that they are working properly. Obtain bridge design drawings, including relevant plans, elevations, sections and details. Understand the design requirements, size specifications and the geometry of the crash barrier.

[0069] When measuring and setting out: Site survey: Conduct a detailed survey at the construction site, including the bridge deck, the edge of the bridge deck, etc., mark the installation location of the crash wall, and determine the starting and ending points of the wall. Set the benchmark: Select appropriate benchmarks in the construction area for subsequent measurement and setting out. The selection of benchmarks should take into account easy identification, stability and relationship with the design coordinates. Establish a coordinate system: Establish a coordinate system for the construction site to ensure consistency with the coordinate system on the design drawings. Use a measuring instrument such as a total station to measure coordinates and associate the benchmark points with the points on the design drawings. Set out markings: According to the size and location requirements on the design drawings, set out markings in the construction area. You can use marking spray paint or other marking tools to mark the key control points at the starting and ending points of the wall and at the corners. Measure the elevation of the control point: Use an instrument such as a level or total station to measure the elevation of the benchmark point and other control points. Make sure that all measurements refer to the same elevation benchmark to ensure the verticality of the wall. Adjustment and correction: Make multiple measurements of the key control points to verify their stability and consistency. If errors are found in the layout during inspection, adjustments and corrections should be made to ensure that the adjusted layout meets the design requirements.

[0070] When preparing the ground and making elevation tape: Clean up the floating dust and garbage in the pouring area to ensure that the construction area is clean and tidy. Level the ground in the construction area, fill or polish the potholes, grooves and protrusions on the bridge deck to ensure that the bridge deck is flat. Use a level, total station or other precise measuring equipment to measure the elevation of the benchmark point and use it as the benchmark for the elevation. Mark the elevation tape along the pouring contour of the crash barrier to determine the height of the concrete pouring. Markings can be made using markers or other markers. Adjust the position and height of the elevation tape according to design requirements to ensure that it accurately reflects the design elevation of the crash barrier.

[0071] When grinding and trial assembling the formwork: Before pouring the bridge crash wall, grinding and trial assembling the crash wall formwork is an important step to ensure that the final concrete wall surface is smooth and consistent, and to prevent deformation or defects in the formwork. Before starting to grind, check the flatness of the formwork to ensure that there are no obvious bumps, cracks or damage. Repair or replace any damaged formwork. Use sandpaper, grinding wheel or other suitable grinding tools to grind the surface of the formwork to ensure that the surface is smooth and uniform. The purpose of grinding is to eliminate concrete residues, flaws and unevenness on the surface of the formwork. Pay special attention to the corners of the formwork to ensure that the corners are smooth and meet the design requirements. Test assemble the formwork according to the design drawings to ensure that the size and shape of the formwork are consistent with the design. According to the results of the trial assembly, make adjustments as needed to ensure the size of the formwork is accurate.

[0072] When tying the guardrail steel bars: clean the rust, oil and other debris on the surface of the steel bars to ensure that the surface of the steel bars is clean, which is conducive to the bonding of concrete and steel bars. Prepare the required length and diameter of steel bars according to the design requirements. Ensure that the steel bars meet the relevant standards and specifications. Set up appropriate brackets in the construction area of ​​the crash barrier to ensure the correct positioning and support of the steel bars to prevent displacement during concrete pouring. Use tying tools (such as tying machines or tying pliers) to tie according to the layout requirements on the drawings. Generally, tying should ensure that there are enough intersections and connections between the steel bars to improve the overall strength. Where connections are required, use appropriate joints for connection. The design of the joints must comply with relevant building standards and specifications. Ensure that the transverse steel bars are tied to increase the overall stability of the crash barrier. Control the density of the tying to ensure that each section of steel bars is properly tied to prevent displacement during concrete pouring. After the tying is completed, conduct acceptance to ensure that the tying meets the design and specification requirements.

[0073] When installing and fixing the inner and outer formworks of the crash barrier: first, lift the processed inner formwork to the layout position by crane, and adjust the formwork to meet the design requirements. Fix one end of the diagonal brace to the bridge deck through angle iron to achieve a preliminary fixation effect, and use tension bolts to tighten the crash wall steel formwork at the lower end of the formwork. Next, start installing and fixing the outer formwork, and lift the processed outer formwork to the specified position by crane. The processing process is similar to the installation of the inner formwork. In order to increase the integrity and reliability of the formwork, the inner and outer side formworks are combined by tie rods passing through the upper and lower positions of the crash barrier. In addition, a connecting plate is used on the top of the crash barrier to connect the two side formworks with high-strength bolts;

[0074] When installing and fixing the steel plate at the true seam; the first upper plate component 11 on the frame 10 feeds the adjusting steel plate to the suspension end of the rotating suspension device 20, and the second upper plate component 12 feeds the end template to the execution end of the hinge bonding device 30, and the hinge bonding device 30 starts the bonding work, and moves the end template into the spraying device 40, and the spraying device 40 sprays the surface of the end template with a demoulding agent and lubricating oil. After completion, the hinge bonding device 30 bonds the end template to the adjusting steel plate to complete the bonding work, and the execution end of the rotating suspension device 20 rotates 180 degrees, and the hinge bonding device 30 can bond another end template to the side wall of the adjusting steel plate again to complete the assembly of the steel plate at the true seam. At this time, the rotating suspension device 20 moves the steel plate at the true seam to the specified position and connects it with the inner and outer template bolts of the anti-collision wall. Use a measuring instrument to measure whether the verticality of the template meets the installation requirements. If not, make adjustments in time to ensure that the verticality of the concrete at the true seam meets the specification requirements;

[0075] When installing and fixing the template at the end: hoist the end template to the designed position, connect the end template with the inner and outer templates with high-strength bolts, and use the support rod to apply a thrust to the end template to prevent the template from exploding during concrete pouring;

[0076] When checking and plugging leaks: First, carefully check the appearance of the crash wall template to see if there are cracks, deformations, defects or other abnormalities caused by the installation process. Pay special attention to the joints, corners and intersections. Check whether the template is perfectly fitted to the bridge deck without gaps. If it is found that the template is not completely fitted to the bridge deck, recheck the installation position of the template to ensure that the template fits the bridge deck correctly. It may be necessary to adjust the supporting structure or reinstall the template to ensure that it fits the bridge deck. If this does not work, take certain plugging measures, such as using a special caulking agent to fill the gap where the template and the bridge deck are not fitted. The caulking agent should be water-resistant, weather-resistant and durable to ensure that it is not easy to crack or fall off after caulking.

[0077] When reviewing the template installation position: Use the detailed design drawings of the crash barrier for review. The drawings include the exact position, inclination and other design requirements of the template. Use measuring tools to check whether the position of the template is consistent with the position marked on the design drawings. Pay special attention to the starting and ending points of the template. Use measuring tools such as levels and plumb meters to check the horizontality and verticality of the template. Use an inclinometer or other related tools to check whether the inclination of the crash barrier is accurate. Check the connection parts of the template to ensure that the connectors or bolts are firmly fixed and not easy to loosen. Check the supporting structure of the template to ensure that the supporting structure is firm and stable. If any problems that do not meet the design requirements are found during the review, take corrective measures in a timely manner to ensure that the structure and shape of the crash barrier meet the design standards;

[0078] When pouring concrete in layers: The pouring of crash barrier formwork concrete is a very important part of high-speed rail project construction, and the material used is C30 ready-mixed concrete. According to the shape of the crash barrier and construction requirements, the crash barrier is poured in layers, generally in layers on the shady slope or chamfered position, and the pouring thickness of each layer does not exceed 30cm. In order to ensure the uniformity and fluidity of the concrete and prevent the generation of bubbles, the pouring is generally started from one end to the other end in an inclined state with the entire section. After pouring each layer of concrete, use a vibrator to vibrate the concrete to ensure the density and quality of the concrete, and close the surface in time after the vibration is completed;

[0079] When removing the adjustment steel plate: After all the concrete is built, according to the temperature, humidity and other conditions, after the concrete is initially set, the adjustment steel plate at the true seam is removed. First, remove the fixing bolts at the middle true seam, install the cable to the upper grip of the steel plate, and use the crane to slowly pull out the middle adjustment steel plate. The pulling process can only be carried out in a vertical position, and cannot be pulled out at an angle, otherwise the steel plate will be damaged;

[0080] When removing the formwork: Prepare the concrete samples collected from the on-site pouring into cubes of standard size, and carry out strength tests after a certain number of days of curing under standard conditions. Remove the formwork after reaching 70% of the design strength. Before removing the formwork, ensure that the construction site is clean and tidy, and there is no debris to hinder the demolding work. Clean the construction area and remove unnecessary tools and materials. Carefully check the status of the anti-collision wall formwork. Make sure that the formwork is not damaged or deformed and can be removed safely. Unfasten the formwork connectors, such as bolts, nuts, etc. Make sure that all connection parts are loose. Use appropriate demolding tools, such as formwork demolding hammers, demolding hammers, etc., to gently tap or pry the formwork so that it gradually separates from the concrete. Remove the formwork in sections according to the design and installation method of the formwork. First remove the steel plate at the true joint and then remove the inner and outer formwork. Handle the removed formwork carefully to avoid collision, falling and scratching to maintain the integrity of the formwork. After completing the formwork removal, clean up the construction site, including cleaning up concrete debris and other debris, to ensure the cleanliness of the construction site. Move the formwork to the next construction site and secure it appropriately to ensure it is not damaged during transportation.

[0081] When sprinkling water for curing: In the early stage of curing, use a breathable protective material (such as wet geotextile) to cover the concrete surface to slow down the evaporation of water and help the concrete solidify better. At the same time, it can also protect the concrete surface from drastic temperature changes, such as avoiding direct sunlight and preventing a sharp drop in temperature at night, which helps prevent cracking on the concrete surface. Make sure the surface is always moist. Spray water regularly to prevent water loss. The specific wet curing time depends on the concrete mix ratio and environmental conditions.
