Construction method for repairing cracks

Abstract

The present invention discloses a construction method for repairing cracks ( 1 ), comprising the following steps: i) coating a solvent ( 2 ) capable of interfusing with asphalt and dust to improve the caking property between the seal repairing material and cracks ( 1 ); ii) scattering high-intensity fibers ( 3 ) with suitable length and size in diameter, usually less than 1 mm on the cracks ( 1 ), wherein longitudinal directions of most fibers ( 3 ) are crossed with the trends of the cracks ( 1 ), and lapped with each other or form a reticular structure; iii) pouring asphalt or macromolecule glue into the cracks ( 1 ), or adhering a strip repairing material ( 4 ) onto the cracks ( 1 ), whereby the fibers ( 3 ) are bonded to the seal repairing material automatically. The construction method enables the repairing material to be bonded to and interfused with the fibers ( 3 ), achieving a repairing effect with excellent expansibility and low-temperature resistance.

         5 . The construction method according to  claim 1 , wherein the seal repairing material is automatically bonded to and interfused with the fibers. 
     
     
         6 . The construction method according to  claim 1 , wherein the seal repairing material forms a flexible seal repairing layer having good expansibility and low-temperature cracking resistance, and crack prevention capabilities. 
     
     
         7 . The construction method according to  claim 1 , wherein the seal repairing material is asphalt, modified asphalt, silica-gel, synthetic glue, asphalt strip, water stop strip, and water-proof roll. 
     
     
         8 . The construction method according to  claim 1 , the solvent is a mixture of oil and water such as the mixture of diesel oil, water and emulsified bitumen. 
     
     
         9 . The construction method according to  claim 1 , the high-intensity fibers are small pieces of tires which are made of robbers and fibers, prefer used tires which are able to generate high strength of fiber materials. 
     
     
         10 . The construction method according to  claim 1 , said asphalt or macromolecule glue is bitumen 70/100 or SBS modified asphalt. 
     
     
         11 . A construction kit for repairing cracks of buildings, said kit comprises a solvent capable of interfusing with asphalt and dust on cracks, high-intensity fibers with various length and size, and seal repairing material. 
     
     
         12 . The construction kit according  claim 11 , wherein the solvent is capable of interfusing with loose dust and asphalt on crack surfaces. 
     
     
         13 . The construction kit according  claim 11 , the solvent is a mixture of oil and water such as the mixture of diesel oil, water and emulsified bitumen.
