Hydraulic engineering detachable U-shaped crawling ladder and manufacture method thereof
The invention discloses a hydraulic engineering detachable U-shaped crawling ladder and a manufacture method thereof. The hydraulic engineering detachable U-shaped 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; the other end of the first contention piece is provided with an opening the nick of which is upward, one end of the pedal is overlapped in the nick; the second contention piece being parallel to the wall vertically penetrates through the first contention piece and the pedal and the pedal can surround the second contention piece to turn over upwards. The hydraulic engineering detachable U-shaped crawling ladder is simple in design, practical in use and easy to realize. The first contention piece is connected with the pedal through the second contention piece bolt, the crawling ladder is convenient to dismount and maintain.
