Beschreibung
Zusammenfassung:	The invention discloses a tunnel lining small cavity reinforcing high polymer material and an injection device, the high polymer material comprises the following raw materials in parts by mass: 100-150 parts of isocyanate, 100-150 parts of polyether polyol, 0.4-3.6 parts of an A33 catalyst, 4-12 parts of a chain extender, the cyanate is polymethylene polyphenyl polyisocyanate PAPI, and the injection device is an injection device. And the content of isocyanato in the polymethylene polyphenyl polyisocyanate (PAPI) is 31.26%. By adjusting the ratio of the two-component polyurethane, the compression strength of the two-component polyurethane can reach 80 MPa or above, the tensile strength of the two-component polyurethane can reach 50 MPa or above, the bonding strength of the two-component polyurethane can reach 1.1 MPa or above, and the two-component polyurethane has the advantages of being high in compression strength, tensile strength and bonding strength and meanwhile meets the requirement for tunnel cavity r
