Nrog rau kev loj hlob sai ntawm kev thauj mus los infrastructure,txoj kev grouting thiab pavement stabilizationtau dhau los ua qhov tseem ceeb rau kev ncua txoj kev pabcuam lub neej.Polyurethane rigid foam raw khoom rau txoj kev groutingyog tam sim no dav lees paub tias yog ib qho ntawm cov kev daws teeb meem zoo tshaj plaws thiab ruaj khov rau qhov tsis muaj qhov txhaws, tawg sealing, thiab subgrade reinforcement.
Piv nrog cov tsoos cement-raws li cov ntaub ntawv grouting,PU tawv ua npuas ncauj grouting tshuabmuabceev cov tshuaj tiv thaiv ceev, siab expansion piv, tsawg viscosity, thiab zoo heev bonding zog. Tom qab txhaj tshuaj, cov npuas dej nthuav dav sai, sau cov voids zais hauv qab pob zeb lossis asphalt pavement, thiab tsim cov ntaub ntawv.siab -lub zog kaw- cell qauvuas tiv taus dej nkag thiab ntev - lub sij hawm deformation.
Pebpolyurethane rigid ua npuas ncauj raw cov ntaub ntawv rau txoj kev grouting daim ntaub ntawvyog tsim tshwj xeeb rau kev xa:
Tswj expansion siab, zam kev puas tsuaj pavement theem
Siab compressive zoghaum rau cov tsheb thauj khoom hnyav
Zoo dej tsis kam, zoo tagnrho rau cov av ntub thiab underground ib puag ncig
Fast curing lub sij hawm, ua kom txoj kev rov qhib sai sai
Cov khoom siv raw no tau siv dav hauvKev kho kev loj tawg, choj lawj grouting, tshav dav hlau khiav stabilization, lub nroog txoj kev tu, thiab qhov av void filling. Lawv qhov kev ua tau zoo tshaj plaws txo qis kev txij nkawm thiab ntev - cov nqi kho lub sijhawm.
Raws li cov tswv infrastructure nce tsom mus rautxhim kho txoj kev ua tau zoo, cov khoom siv ruaj khov, thiab txo qis qis, polyurethane txhav ua npuas ncauj grouting tau dhau los ua kev xaiv thoob ntiaj teb.
