The invention discloses a wellhead cutting and forming device and a construction method thereof. The wellhead cutting and forming device comprises a cutting mechanism and a hoisting mechanism, the cutting mechanism comprises a bottom plate provided with a first fastener and a cutting steel ring provided with a second fastener, a cutting edge is arranged at the upper end of the cutting steel ring, and before a pavement structure layer is paved, the bottom plate and the cutting steel ring are fixed above a well mouth, after a pavement structure layer is paved, the pavement structure layer right above the first fastener and the second fastener is removed, the hoisting mechanism is connected with the second fastener to hoist the cutting steel ring, and the cutting edge vertically cuts the pavement structure layer above the well mouth to form the regular well mouth with the same diameter as a walling crib. And the hoisting mechanism is connected with the first fastener to hoist the bottom plate and the pavement structure layer on the bottom plate to be taken out together, so that the well ring is well attached to the well mouth during subsequent well ring installation, secondary mixed material filling is not needed, the integrity of the pavement structure layer on the periphery of the well mouth is guaranteed, and settlement of the pavement on the periphery of the well mouth is avoided.
Description
technical field [0001] The invention relates to the field of road construction. More specifically, the present invention relates to a wellhead cutting and forming device and its construction method. Background technique [0002] At present, in the construction of the pavement structure layer of municipal roads, the wellhead construction within the pavement range basically uses steel plates to cover the wellhead and then paves the structure layer. Install the well ring. The above-mentioned wellhead construction methods manually excavate the pavement structure layer on the wellhead to cause a huge disturbance to the surrounding structure layer of the wellhead, which cannot guarantee the quality of the pavement around the well. Filling the mixture, the post-filling mixture cannot be rolled by a road roller, the integrity of the original pavement structure layer is poor, and the flatness is difficult to control, and the winter in the Northeast is cold, and the change of spring...
