Description

Technical Field

[0001] The invention relates to a method for installing a dynamic weighing sensor, and in particular to a method for flattening and integrating a dynamic weighing sensor used for bridges and road surfaces. Background Art

[0002] In recent years, with the development and needs of social economy, transportation has become more and more developed, and heavy vehicle loads have caused tremendous pressure on existing infrastructure structures such as pavements and bridge decks. In order to ensure the safe operation of highways, more attention is paid to the health monitoring and management of infrastructure, and the supervision of overweight vehicles is also increased. Installing dynamic weighing sensors on the road surface can achieve accurate and reliable measurement of vehicle weight under complex traffic flow. Therefore, dynamic weighing sensors play an important role in traffic flow monitoring and vehicle overweight, and can be used for monitoring and detection of vehicle loads. Dynamic weighing systems are widely installed or will be installed on different sections of urban roads and highways in my country.

[0003] In the existing dynamic weighing sensor installation technology, it is necessary to groove the road surface, put the weighing sensor into the groove, and then fill the groove with filler, which is usually done by manually aligning the filler directly with the groove opening for mobile filling and repair. This filling method is difficult to accurately control the filling amount, and it is easy to cause the road surface near the installation location to be uneven, forming a concave and convex surface, which not only affects the appearance of the road, but also affects the driving comfort to a certain extent.

[0004] The main reasons for uneven road surface caused by dynamic weighing sensor installation are: 1) During the filling process of the sealant, there is a lack of limit guide measures. Even if it is a straight regular slot, manual filling will still deviate from the slot and spill onto the road surface on both sides of the slot; 2) The height of the sealant will drop after solidification. If the height of the sealant is not properly controlled during filling, it is easy to cause uneven road surface. Filling too high will easily cause the sealant to overflow to the road surface, causing the road surface and the slot to bulge on both sides. Filling too low will cause the slot to sink and even require secondary filling. Therefore, there is an urgent need for a dynamic weighing sensor installation method that is convenient to construct and can ensure a flat road surface after installation. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a flat integrated installation method for dynamic weighing sensors used for bridges and road pavements, which quickly defines the slotting position through a template and controls the filling height of the sealant with the template scale, thereby improving the smoothness of the road surface and reducing road noise.

[0006] In order to solve the above technical problems, the present invention provides a flat integrated installation method for dynamic weighing sensors for bridges and road pavements, comprising at least two right-angle templates for road surface positioning, each right-angle template comprising a lateral module and a bottom module, the lateral module and the bottom module are fixedly connected to form a right-angle template; the lateral module is fitted with the slotted facade, and reserved holes for segment splicing are reserved at both ends, and scale lines are marked on the lateral module; the bottom module is fitted with the road surface, and reserved holes for consolidation with the road surface are reserved; the right angle line of the right angle template is fitted with the side lines of the road surface slot on both sides, and the spacing between the two right angle templates is the road surface slot width; the flat integrated installation method for the dynamic weighing sensor, the specific steps of which are as follows:

[0007] S1: placing at least two right-angle templates for road surface limitation at the road surface groove positions respectively, and adjusting the distance between the two templates to a predetermined groove width, fixing the bottom surface module to the road surface, and quickly limiting the groove position by the right-angle templates;

[0008] S2: Use the reserved holes of the lateral modules to perform segmental splicing of multiple lateral modules;

[0009] S3: The road surface is grooved to a preset depth of 3-6 cm, and the dynamic weighing sensor is placed flat in the groove along the width of the lane;

[0011] S5: Fill the slot with caulking agent to a certain specified height, wait for the caulking agent to solidify, remove the right-angle template, and fill the opening left by the bottom module.

[0013] S1: Scale the lateral modules;

[0014] S2: Determine the fall back height of the caulking agent by means of a small section test. Take a 3-6 cm long slot for small section test filling. Repeat at least twice to determine the fall back height of the caulking agent.

[0015] S3: Then fill the groove with caulking agent, the filling height = actual caulking height + the fall back height of the caulking agent, so that the filling surface is flush with the road surface.

[0033] S1: Making a right-angle template 3: Welding the lateral module 32 and the bottom module 31 into a right-angle template 3, and dividing the part of the lateral module 32 close to the road surface 1 by scale 5; reserving bolt holes for fixing to the bridge deck at both ends of the bottom module 31, and reserving bolt holes on the lateral module 32 for longitudinal splicing of module segments; the right-angle template is a right-angle steel template;

[0034] S2: Fix the right-angle template 3: Install the right-angle template 3 on both sides of the road surface groove 2, the bottom surface of the bottom module 31 is in contact with the road surface, the side module 32 is tangent to the vertical surface of the groove, the right angle line is in contact with the side lines of the groove, and the spacing between the right-angle templates 3 on both sides is 2-4 cm of the width of the road surface groove;

[0035] S3: Grooving the road surface and placing the dynamic weighing sensor: According to the position of the right-angle template 3, the road surface is limitedly grooved. After the groove is grooved to a suitable depth of 3-6 cm, the dynamic weighing sensor 6 is placed in the groove along the width of the lane;

[0036] S4: Determine the fall-back height of the caulking agent: Since there is a fall-back height difference between the filling height and the solidification height of the caulking agent, it is necessary to determine the fall-back height of the caulking agent through a small section test. Take a 3-6cm length slot for a small section test filling, and repeat 2-3 times to determine the fall-back height of the caulking agent to ensure that the road surface after filling remains flat; when the depth and width of the road surface groove are fixed, the filling height of the caulking agent after the dynamic weighing sensor 6 is placed is mainly related to the type of caulking agent. The special silicone rubber of the weighing sensor is used on site. The actual caulking height is quickly determined through on-site tests. The filling fall-back height of the silicone rubber is generally 2mm, that is, the filling height = the actual caulking height + 2;

[0037] S5: Filling the sealant 7; filling the sealant 7 into the groove along the road width direction to a specified filling height;

[0038] S6: Remove the right-angle template to complete the installation: Wait for the sealant to solidify and fall back, remove the right-angle templates 3 on both sides of the road surface, and fill the road surface openings left by the bottom module 31, thus completing the rapid installation of the dynamic weighing sensor for the road surface or bridge deck, and ensuring the flatness of the road surface after installation.

[0039] The gaps involved in this method are small-sized transverse road surface gaps that have been artificially processed to be relatively regular. The road surface on both sides of the gaps has good flatness and no bumps or depressions.

[0040] The present invention also provides a method for filling a gap filler with a limited height, comprising the following steps:

[0041] S1: Divide the lateral module 32 into 5 scales;

[0042] S2: Determine the fall-back height of the filling sealant by a small section test, take a 3-6 cm length slot for small section test filling, repeat 2-3 times to determine the fall-back height of the filling sealant; this specific embodiment uses a special silicone rubber for the weighing sensor, the actual filling height is the actual on-site filling to the road surface, the filling fall-back height of the silicone rubber is generally 2mm, that is, the filling height = the actual filling height d + 2;

[0043] S3: Then fill the groove with caulking agent to a determined height so that the filling surface is flush with the road surface.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
