Support mortar is a high quality cement-based composite material for road and railway bridge support installation. Since the support mortar uses a variety of high performance additives, the surface is particularly smooth and smooth after completion. It overcomes the shortcomings of traditional mortar unevenness, cracking and spalling, and has the characteristics of self-leveling, high early strength, high strength, no shrinkage, high wear resistance and convenient construction.
First, the characteristics of the support mortar
1. The supporting mortar has excellent fluidity, self-flow leveling, no need to vibrate, and pressure, and the construction speed is fast and convenient.
2. The support mortar has a very high hour strength, high strength at the end, and does not shrink. According to different construction temperatures, the compressive strength of 20-40Mpa can be obtained in 2 hours, and the flexural strength is high.
3. The support mortar has micro-expansion properties and excellent crack resistance.
4, the support mortar adapts to a wide temperature range, under the conditions of -5 ° C ~ -35 ° C, without any auxiliary insulation or cooling measures can be applied. Under high or low temperature conditions, the need for strength development and construction fluidity can be ensured at the same time.
5. Support mortar is suitable for repair, track filling and support grouting, especially for high-speed railway bridge bearings or track filling. It can also be used for local leveling of concrete beams or repair of concrete piers.
6. The supporting mortar meets the requirements of the Temporary Technical Conditions for Concrete Precast Beams of Passenger Dedicated Lines and the Temporary Technical Conditions for Basin Rubber Bearings for Passenger Dedicated Line Bridges.
Second, the construction method of the support mortar:
1. The surface of the support pad on the support installation site is chiseled to remove the debris left in the anchor bolt hole, and then the surface of the support pad is saturated with water, but there must be no clear water during construction.
2. Install the support in place, wedge the small steel wedge into the support, adjust the support to the design elevation, and leave a gap of 20-30mm between the bottom of the support and the support pad.
3. After carefully checking the center position and elevation of the support, install the grouting template, and the template and the top surface of the cushion should take reliable measures to prevent slurry leakage during gravity grouting. The grout is filled by gravity grouting. Before the grouting, the required volume of the slurry should be initially measured. The actual amount of the infused slurry should not cause excessive error with the calculated value to prevent the lack of slurry in the middle.
4. Water to material ratio = 0.135-0.15 (weight ratio). Water should be added to the mixing tank first, then gradually added to the weighed slurry, and then stirred with an electric mixer while feeding, until the powder is completely added, and stirring is continued for 2-3 minutes to make the slurry uniform. The stirred slurry should be filled in 10 minutes.
5. After the grouting material reaches the specified strength, remove the template and the steel wedge, check whether there is any slurry leakage, replenish the gap between the leakage and the steel wedge, tighten the anchor bolt, and then install the beam support. Base plate.
