The　chemical　grouting　technique　has　become　one　of　effective　approaches　to　soil　reinforcement　and　maintenance　in　the　field　of　geotechnical　and　hydraulic　engineering.　According　to　the　high　pressure　and　large　flow　rated　conditions,　in　which　the　pressure　is　10　MPa　and　the　flow　rate　is　120　L/min,　the　structure　form　of　valve　plate　of　axial　piston　pump　is　determined.　Furthermore,　the　essential　parts　of　pump　including　piston,　valve　plate,　slipper　and　bearing　are　designed.　Finally,　the　structure　of　valve　plate　axial　piston　pump　for　chemical　grouting　is　integrated,　which　provides　the　basis　for　subsequent　processing　and　performance　test　of　prototype.
