The utility model provides a deviational survey pipe based on in deep basal pit envelope concrete, includes PVC deviational survey pipe and steel casing pipe, vertical the burying underground in envelope concrete layer of PVC deviational survey pipe, and the steel reinforcement cage bottom among PVC deviational survey pipe lower extreme and the envelope concrete layer flushes, and the upper end extends to the hat roof beam top that is located the envelope concrete layer top, steel casing pipe and the coaxial setting of PVC deviational survey pipe, the steel casing pipe bottom is buried underground in envelope concrete layer, and upper portion exceeds steel reinforcement cage 20cm. The utility model discloses use the PVC deviational survey to manage to the major structure, adopt the coaxial setting of steel casing pipe and PVC deviational survey pipe, prevent that it damages deviational survey pipe major structure to remove the super concrete in -process of irritating at the chisel, avoid because of deviational survey pipe suffers the intraductal disintegrating slag of deviational survey clearance that construction destructions need go on, joins two pipes together and stifled pipe work such as scrap even, also avoided simultaneously influence the later stage and monitoring the work of measurationing and excavate the safe risk of bringing for the deep basal pit because of the deviational survey pipe is destroyed by the construction.
