Bearing mortar is a high-performance modified cement-based grouting material that uses a variety of organic and inorganic additives and has the characteristics of high strength, no shrinkage, and good durability. , can self-flow leveling, can be operated for a long time, and the surface is smooth and flat after completion, overcoming the shortcomings of traditional mortar such as unevenness, easy cracking, peeling and powdering, etc. It is specially designed for simply supported box beam basin rubber bearings for railway passenger lines It is developed by gravity grouting, and its performance fully meets the requirements of the "Interim Technical Conditions for Prefabricated Simply Supported Box Beam Basin Rubber Bearings for Railways and Passenger Dedicated Lines"
This product has the following characteristics:
.Bearing mortar -Expansion function that meets technical requirements: ensures the firm bonding between the slurry and the grouting part, so that the load function can be effectively transferred to the foundation
. Bearing mortar-high flow performance: has great fluidity and can be used in Flows to various parts that require grouting without adding external force
. Bearing mortar - good workability: not only flows well but also lasts for a long time, has good cohesion, does not separate or bleed.
.Bearing mortar - high strength: high compressive strength, high strength in the later period and no shrinkage
.Bearing mortar - low negative temperature construction: the strength still increases significantly under low and negative temperatures , effectively solving problems such as winter construction
. Bearing mortar - good durability: 10,000 fatigue tests, 10,000 freeze-thaw cycle tests, no significant change in strength, anti-permeability, anti-freeze, and anti-corrosion properties. Performance
.Bearing mortar-does not contain chloride and has no corrosive effect on equipment and steel bars
.Bearing mortar-easy to use: the finished product is dry-mixed mortar, which can be used after adding water according to the construction site regulations
br/> .This product is suitable for grouting in the erection of various prefabricated beams, and is used for grouting between the base plate of the support and the supporting padding stone of the pier.
, How to use
Base surface treatment: Chisel the surface of the supporting pad at the installation part of the bearing, remove debris in the reserved holes, and install the template for grouting. The top surface of the template and pad should be Reliable measures to prevent grout leakage during gravity grouting. The base surface to be grouted should be cleaned of dust, oil, other dirt and other substances that are not conducive to bonding. The base surface should be moistened with clean water until it is saturated, but no open water should be left during construction< br/> Lift the prefabricated box girder (with supports), place the box girder on the temporary support jack, and adjust the fulcrum elevation of the beam body through the jack
After the beam body is in place, install the base plate of the support and the support pad of the pier. A 3-inch gap should be reserved between the stones to allow gravity grouting to be used to fill the bridge bearing mortar
Gravity grouting is used to grout the gaps at the bottom of the bearing and the anchor holes. The grouting process should be from the center of the bearing to the surrounding areas. Until the grouting material is completely filled from the gap between the formwork and the base plate of the support. The required grout volume should be initially measured before grouting. The actual grout quantity should not have too large an error with the calculated value to prevent lack of grout in the middle. br/> The slurry is prepared according to the ratio of powder: water: 3. (weight ratio). Water should be added into the mixing barrel first, then gradually add the weighed grouting material, and stir with an electric mixing gun while adding the material. After all the powder has been added, continue stirring for another minute to make the slurry uniform
After the grouting material reaches the specified strength, remove the formwork, check whether there is grout leakage, and repair the grout leakage
Tighten the lower support Slab anchor bolts, remove the angle steel connecting the upper and lower supports, remove the temporary jacks, and install the support steel hoarding
