Description

A modular multi-functional integrated traffic mast and its design method and installation method Technical field

The invention relates to the technical field of traffic gantry, and in particular to a modular multi-functional integrated traffic gantry, a design method, and an installation method.

Background technique

Traffic gantry is a type of gantry installed on traffic roads. It plays a role in limiting the height of the vehicle body, prompting driver information, collecting vehicle-related data, and publicizing traffic information. Its structure must have a certain load resistance capacity. Traffic gantry The installation of the rack must first ensure traffic safety and avoid safety hazards.

The existing technology takes a long time to construct traffic gantry on traffic roads. Taking a 100km highway as an example, if an interchange is set up for 10km, a total of 85 sets of sign traffic gantry and electromechanical traffic gantry need to be arranged. At present, the largest domestic gantry manufacturer can produce 30 sets of gantry in one month, and it takes about 3 months to produce 85 sets of gantry. The above time is only the time required for processing by the manufacturer. During the construction of the traffic gantry, the structure of the traffic gantry can only be made after the foundation pit and foundation are completed. This is due to reasons such as construction personnel and construction accuracy, and the location of the designed foundation pit. There are errors in the actual construction with the actual measured foundation pit positions. It is easy to have a deviation of several centimeters between foundation pits, resulting in the traffic mast not being produced in advance, otherwise the produced traffic mast will not match the on-site conditions. Therefore, before the manufacturer produces, it is necessary to design the span of the assembled traffic mast based on the on-site foundation pit spacing measurement data, and then feedback the design data to the relevant manufacturers for production. The manufacturer can also base on the original design based on the feedback data. After adjustment, production is carried out, and there is a sequence between on-site measurement and processing by the manufacturer before leaving the factory, which leads to a long time lag during construction. The traffic gantry can only be transported to the site for installation after the manufacturer has completed it.

Therefore, the existing traffic mast installation consumes a lot of time, and the installation of the traffic mast requires temporary road closure. If the mast is installed on a road with a large traffic flow, it will cause traffic congestion and seriously affect the traffic of vehicles. The traffic mast is The construction time is particularly important. At the same time, there is no modular traffic mast structure in the existing technology, and unified design cannot be achieved. The design of the traffic mast needs to take into account parameters such as lane span, wind speed, load, etc. These parameters will have an impact on the traffic mast. As a result, the traffic gantry of each section of road needs to be designed separately. Currently, there are no unified standards and specifications. The design and construction of traffic gantry across the country consumes a lot of energy and time for the entire transportation industry personnel.

According to the required installation equipment, select the type of traffic mast to determine the height H. In this embodiment, the number of lanes is Two-way eight lanes, span range l is 38.1m, choose the type of traffic gantry. The type of traffic gantry is determined according to the needs of the road section. Select the sign traffic gantry or the electromechanical integrated traffic gantry according to the needs; the traffic gantry The structure and foundation 1 should be standardized based on the different technical standards (such as the number of lanes, design speed, etc.) and regional characteristics of the main project, and should be combined with changes in bridge guardrails, fills, excavations, central and roadside facilities where the facilities are located, Adjustable; the span of the sign traffic mast includes the distance across half of the two-way four lanes, the distance across half of the two-way six lanes, the distance across half of the two-way eight lanes, the distance across the full width of the two-way four lanes, and the distance across the full width of the two-way six lanes.

S2. Modularize the modular multi-functional integrated traffic gantry. Discrete means dismantling the traffic gantry into multiple independent modules. The discrete modules are foundation 1, column 2, adjustment section 3 and beam 4. Beam 4 includes multiple sections of beams. Standard section 41; the length of the standard section 41 of the beam is 4m; the length range of the adjustment section 3 is 1.050m ~ 3.050m; through the length setting and quantity setting of the standard section of the horizontal bar, and the length range setting of the adjustment section 3, the traffic mast can be adjusted Adjust the span range to facilitate the span of the traffic gantry to match the actual measured foundation pit spacing; by discretizing the traffic gantry into a multi-module structure, construction and installation are facilitated;

S3. Determine the length of the crossbeam 4 through the span range l, and then determine the length of the crossbeam standard section 41 based on the length of the crossbeam standard section 41 being [1, 3] times the height of the crossbeam standard section 41, and then determine the number and adjustment sections of the crossbeam standard section 41 3 length; the length of the beam 4 and the adjustment section 3 can be adjusted according to the site conditions.

The surface category is divided into four categories: A, B, C, and D according to the roughness. The surface category in this embodiment is A. According to the equivalent static gust wind speed range, The wind load is determined based on the gust speed range. Among them, the basic wind speed value is converted into the equivalent static gust wind speed value corresponding to the surface category, and the equivalent static gust wind speed value is converted into the wind load. Both are existing technologies; the three ranges of the design reference wind speed are It is divided into: (0m/s, 35m/s], (35m/s, 45m/s] and (45m/s, 55m/s].

After considering the bridge deck height The design basis wind speed can be controlled at 35m/s. Special areas and large structures such as cross-sea bridges can basically be controlled at 35m/s~45m/s and 45m/s~55m/s. Comprehensive analysis shows that the design basis wind speed is based on three Gear control, respectively (0m/s, 35m/s], (35m/s, 45m/s] and (45m/s, 55m/s], when the design basis wind speed is greater than 55m/s, the mast should be specially designed.
