In view of the recent consultation and sharing of dry goods by netizens: what are the more installation methods of high-speed rail bridge deck railings, the following is a summary of the content related to this, and you can pay attention to it if you want to know more about it.
High-speed rail bridge deck railings are an important facility installed on high-speed rail bridges to protect the safety of travel lanes and sidewalks. The following is a brief introduction to several common installation methods of high-speed rail bridge deck railings, and introduces their installation, construction, and precautions.
1. Bolt-on installation
Bolt-on type is a common way to install railings on high-speed rail bridge decks. It is characterized by the use of bolts to fasten the railings to the bridge deck. When installing, it is first necessary to punch holes in the bridge deck according to the design requirements and fix them with suitable bolts. The railing parts are then mounted on bolts, reinforced by fastening nuts. During construction, it is necessary to pay attention to the material selection and fastening strength of the bolts to ensure the stability and safety of the railing.
2.Assembled installation:
Assembled type is a convenient and fast way to install railings on high-speed rail bridge decks. It is characterized by the fact that the railing is made into prefabricated components and assembled and installed on site. During installation, it is necessary to reserve the installation position on the bridge deck, and then the prefabricated railing components are spliced and assembled according to the design requirements, and connected and fixed through the connectors. Assembled installation requires attention to the accuracy of the components and the reliability of the connectors.
3.Welded mounting:
Welded type is a commonly used high-speed rail bridge deck railing installation method, which is characterized by fixing the railing on the bridge deck by welding. During installation, it is necessary to carry out pre-welding preparations on the bridge deck, such as cleaning the dirt and rust of the welded parts. The railing is then positioned and welded to the bridge deck. During construction, it is necessary to pay attention to ensure the quality of welding and avoid cracks or unfirm welding.
When installing the railings of the high-speed rail bridge deck, the following points need to be noted:
1. Safety protection: The construction personnel should carry out the necessary safety protection during the construction process and wear the necessary safety equipment, such as safety helmets, protective glasses, gloves, etc., to ensure the safety of the construction personnel.
2.Construction quality: During the installation process, it is necessary to ensure that the installation quality of the railing meets the design requirements, and there can be no loosening, tilting, cracking and other problems to ensure the safety of the railing.
3.Relevant standards: During the construction process, the relevant construction specifications and standards should be strictly adhered to to ensure the compliance and safety of the construction.
The installation method of high-speed rail bridge deck railing has bolt-fixed type, assembled type and welded type, etc., each installation method has its characteristics and applicable scenarios, and the construction process should pay attention to safety protection, ensure the quality of construction, and strictly abide by the relevant standards. In this way, the stability and safety of the railing of the high-speed rail bridge deck can be ensured.
