The invention discloses an integrated device for the foundation excavation and grouting of strip-shaped deep grooves. The integrated device comprises a strip-shaped platelike cutter, a variable-frequency vibratory pile hammer for driving the cutter movement, a negative pressure residue pumping system communicating with a residue pumping guide hole on the cutter, and a grouting system communicatingwith a grouting guide hole on the cutter, wherein a lengthened rod capable of lengthening is arranged between the cutter and the variable-frequency vibratory pile hammer. By the adoption of the technical scheme, the variable-frequency vibratory pile hammer drives the strip-shaped platelike cutter to sink and open grooves; the waste residue generated by the excavation is cleaned through the negative pressure residue pumping system; the cleaning in the excavation grooves is ensured; and when the excavation is completed, a grouting device grouts the inside of the grooves to construct thin retaining walls. 本发明公开了种条形深槽基础开
