Hydraulic engineering detachable crawling ladder and manufacture method thereof
The invention discloses a hydraulic engineering detachable crawling ladder and a manufacture method thereof. The hydraulic engineering detachable crawling ladder comprises a first prefabricated steel plate, a second prefabricated steel plate, a first contention piece, a second contention piece and a pedal, wherein the first prefabricated steel plate and the second prefabricated steel plate are parallel to each other and are embedded in the wall; one end of the first contention piece is respectively fixed on the first prefabricated steel plate and the second prefabricated steel plate; the first contention piece is exposed from the wall; two ends of the second contention piece are respectively provided with the external thread with opposite screwing direction; the other end of the first contention piece is connected with one end of the second contention piece in a detachable mode; the other end of the second contention piece is connected with the pedal in a detachable mode. The first contention piece is respectively fixed on the first prefabricated steel plate and the second prefabricated steel plate, and connected with the second contention piece and the pedal, so that the direct contact between the pedal and the wall is avoided, and the wall falling problem caused by the existing crawling ladder can be avoided.
