SBS modified asphalt waterproofing membrane general agent - discount promotion

Description :

　　 The first main cable strand of the Luding Dadu River Xingkang Grand Bridge on the Yakang Expressway was successfully erected on the afternoon of the 5th, marking the start of the main construction of the upper structure of the bridge. After the completion of the main cable of the bridge, it will enter the steel truss beam hoisting construction.

　　Engineering technicians are currently installing the first main cable strand.

　　It is reported that the Luding Dadu River Xingkang Extra Large Bridge on the Yakang Expressway is a super large cross-border steel truss suspension bridge built in a high-altitude, high seismic intensity zone, and complex wind field environment. The total length of the bridge is 1411 meters, and the main bridge is 1100 meters long. It adopts a steel-concrete composite bridge system and is one of the key control projects of the "one bridge, one tunnel" along the entire Yakang Expressway. It is known as the "Sichuan Tibet Bridge".

　　The main cable of Xingkang Grand Bridge adopts prefabricated parallel steel wire strands (PPWS). There are two main cables in the entire bridge, each with a length of 1754 meters. The self weight of a single main cable is 5234.6 tons, and the designed load-bearing capacity is 15000 tons; A single main cable has 187 strands (a total of 374 strands) with a net weight of 27.9 tons. Each strand is composed of 91 high-strength galvanized steel wires with a diameter of 5.3 millimeters and a nominal tensile strength of 1860 MPa made of SBS modified asphalt waterproofing membrane. The SBS modified asphalt waterproofing membrane has a total of 34034 steel wires for the entire bridge main cable, with a total length of over 60000 kilometers. When connected, they can circle the earth once and a half times.

　　The first main cable strand is crossing the Dadu River. The first main cable strand is crossing the Dadu River.

　　The construction of the lower structure 'two towers and two anchors' of Xingkang Grand Bridge has been completed. After the construction of the traction catwalk pilot cable crossing the Dadu River at the end of 2016, the project construction has fully shifted to the upper structure construction process. The relevant person in charge of the construction of Xingkang Grand Bridge said that the installation of the first main cable strand marks the official start of the main construction of the upper structure of the bridge. The main cable is expected to be completed in August this year, and then enter the steel truss beam hoisting construction. It is expected to be completed and connected by the end of August 2018.

　　It is reported that the Yakang Expressway rapidly climbs from the Sichuan Basin to the Qinghai Tibet Plateau, facing five challenges during the construction process: extremely complex terrain, extremely complex geology, extremely fragile ecological environment, extremely harsh climate conditions, and extremely difficult construction. According to the requirements, the 98 kilometer section from Ya'an to Luding will be completed and opened to traffic ahead of schedule by the end of 2017.

　　1、 Product Introduction

　　SBS elastomer modified asphalt waterproofing membrane is made of SBS (styrene butadiene styrene) thermoplastic elastomer modified asphalt as the dipping material, polyester felt, fiberglass felt, composite tire cloth as the base, and fine sand, mineral particles, PE film, aluminum film and other covering materials.

　　2、 Product Details

　　Product Name: Double Rainbow SBS Modified Asphalt Waterproof Membrane

　　Product Model SH-118

　　Product form: Black roll material

　　Implementing standard GB 18242-2008

　　3、 Product advantages

　　1. Can form a high-strength waterproof layer with strong resistance to pressure water;

　　2. High tensile strength, high elongation, strong adaptability to base shrinkage deformation and cracking;

　　3. Excellent high and low temperature resistance, suitable for both hot and cold regions. SBS is suitable for waterproofing buildings in cold regions with frequent structural deformation, while APP is suitable for waterproofing buildings in high temperature and areas with strong solar radiation;

　　4. Good puncture resistance, abrasion resistance, tear resistance, fatigue resistance, corrosion resistance, mold resistance, and weather resistance;

　　5. Good construction performance, hot melt bonding can be applied all year round, and the hot joints are reliable and durable.

　　4、 Scope of application

　　1. Waterproofing of various industrial and civil building roof projects;

　　2. Waterproofing and moisture-proof of underground engineering in industrial and civil buildings, as well as waterproofing of structures such as indoor swimming pools and fire water pools;

　　3. Waterproofing for municipal engineering projects such as subways, tunnels, concrete paved bridge decks, sewage treatment plants, and landfill sites;

　　4. Waterproof of water conservancy facilities such as canals and pools.

　　5、 Construction technology

　　1. Clean the base surface according to waterproof construction requirements.

　　2. Brushing the bottom layer: Mix the modified asphalt cold base oil evenly and apply it evenly on the base surface, without penetrating the bottom layer

　　Accumulation.

　　3. The sequence of laying rolls is as follows: first high span, then low span, at the same height, from far to near, on the same facade, from high to low

　　Start laying at this location.

　　4. Stretch line and trial laying: The roll material should be trial laid in place first, and then cut correctly according to the required shape before actual bonding can begin.

　　5. Large area laying of roll materials: There are two methods. In actual construction, construction personnel can determine the pasting method based on the site environment, temperature, sunlight and other conditions, but the basic methods are exhaust, compaction

　　The anti wrinkle requirements remain the same.

　　6. After exhausting and compacting the large area of the laid roll material, the roll material is overlapped and sealed, and then the end is fixed and sealed

　　6、 Precautions

　　1. Construction cannot be carried out on contaminated grassroots.

　　2. Roll packaging and isolation film can only be removed before laying and during the next construction process.

　　3. The materials should be stored in a dry and well ventilated warehouse, and should not be exposed to direct sunlight or rain.

　　4. The rolls should be laid flat and stacked at a height not exceeding three layers to avoid contact with benzene and substances that affect the chemical properties of asphalt rolls.

　　7、 Reference dosage

　　 The actual dosage depends on the specific substrate conditions.

　　8、 Shelf life:

　　Under normal storage and transportation conditions, the shelf life is one year.
