Sales hotline: (Mr. Li) Bearing mortar is a high-performance modified cement-based grouting material that uses a variety of organic and inorganic additives. It has the characteristics of high strength, no shrinkage, and good durability. It can self-flow and level, and has a long operating time. Long, and the surface is smooth and flat after completion, which overcomes the shortcomings of traditional mortar such as unevenness, easy cracking, peeling off and powdering. It is specially developed for gravity grouting of simply supported box beam basin rubber bearings for railway passenger lines. 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"
1. This product has the following characteristics:
. Bearing mortar - has expansion that meets technical requirements Function: Ensure the strong bond between the slurry and the grouting part, so that the load function can be effectively transferred to the foundation
. Bearing mortar - high flow performance: It has great fluidity and can flow to the direction without adding external force. Various parts that require grouting
.Bearing mortar - good workability: not only flows well but also lasts for a long time, has good cohesion, does not separate, and does not bleed
.Bearing Mortar - high strength: high compressive strength, high strength in the later stage and no shrinkage
Bearing mortar - low negative temperature construction: the strength still increases significantly at low and negative temperatures, effectively solving the problem of winter construction and other issues
.Bearing mortar - good durability: 10,000 times fatigue test, 10,000 freeze-thaw cycle tests, no significant change in strength, anti-permeability, anti-freeze, and anti-corrosion properties all have good performance
.Support Seat mortar - does not contain chloride and has no corrosive effect on equipment and steel bars
. Support mortar - easy to use: the finished product is dry mixed mortar, which can be used after adding water according to the construction site regulations
. This product is suitable for Grouting used in various prefabricated beam erection, used for grouting between the support bottom plate and the pier support pad.
2. Instructions for use
Base surface treatment: Chisel the surface of the supporting pad for the installation part of the bearing, remove debris from the reserved holes, and install the template for grouting. The template and the top surface of the pad should be Take 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.
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, support it on the bottom plate of the support and the pier. A gap of 3 cm should be reserved between the padding stones to allow gravity grouting to be used to fill the bridge bearing mortar. Use gravity grouting to fill 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, and the actual grout quantity should not have too large an error with the calculated value to prevent lack of grout in the middle.
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. Until all the powder is 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 replenish the leakage grout
Tighten the lower branch The seat plate anchor bolts, remove the angle steel connecting the upper and lower supports, remove the temporary jack, and install the support steel hoarding
