[0002] The existing diaphragm wall slot passageway trestle is usually temporarily made of steel bars, or simply combined by steel wire mesh or steel plate. The existing movable trestle for slot detection is usually temporarily placed by two simple channel steels. The main steps of the steel bar simple passageway trestle construction are as follows: the steel bars are arranged in parallel horizontally, and vertical steel bars are arranged and welded at both ends. The simple passageway trestle is usually uneven in height, and the gap size between the steel bars is different, which easily causes personnel to fall down, and the temporary trestle is easily deviated to cause personnel to fall into the slot, and in serious cases, even causes personnel injury.

[0003] The trestle formed by the steel wire mesh or the steel plate can avoid personnel falling, but still causes the trestle to deviate on the diaphragm wall slot with mud water, and also easily causes personnel injury.

[0004] In addition, the channel steel for slot detection is usually placed on the diaphragm wall slot (the slot periphery usually has mud water at this time), and the detection machine is pushed onto the channel steel for detection according to manual adjustment, which easily causes deviation to cause the machine to fall into the slot, and causes economic loss.
