The level of silicon content in the limestone chemical composition on the hammerhead service life has a direct impact, the higher the silicon content, the shorter the hammer the life of the best-case scenario is less than 2% of silicon content in the limestone. The other hand, limestone compressive strength of high and low and hammer is closely related to life. The higher the compressive strength, fragile worse, the hammer will be a short service life.

Xingang Tianjin Binhai New Area on the 4th road tunnel is designed as dual ten lane viaduct piers and foundation due Jinbin Light effects , driveways not normally traverse . It is required to Tianjin - Binhai Viaduct 339 # ( brake pier ) and 340 # ( Shared pier ) pier for underpinning , underpinning φ2000mm using three and six φ1800mm bored bored . Where three φ2000mm bored pile length 90.00m, 6φ1800mm bored pile length 70.00m. Creepage piles located under the viaduct , viaduct bottom elevation of 10.00m ( Taku elevation , the same below ) , ground elevation of 3.00 ~ 3.50m. Just 7.00m clearance from about underpinning and 340 from the original 339 # # pier is only 7.50m ( see Figure 1 ) . After construction of self-balancing method to test pile bearing capacity testing, meet the design requirements .
