In order to solve the technical problems, the invention adopts a technical scheme that: the utility model provides a folding reinforcement formula foundation ditch emergency ladder, includes ladder top, ladder base and a plurality of extension ladder, the ladder base is beaten into fixed reinforcement downwards and is fixed with foundation ditch bottom soil, the ladder base is equipped with two recesses, the recess is leading-in extension ladder, extension ladder both sides are equipped with hollow ladder post, be connected with the rung between the hollow ladder post, hollow ladder post top-down is leading-in anti-folding reinforcement, extension ladder upper end with ladder top fixed connection, ladder top one side penetrates anti-folding reinforcement is fixed, ladder top opposite side and foundation ditch top use fixed component to link to each other, fixed fastener one end with ladder top welding is fixed, the fastener other end is ninety degrees to the right side and buckles and be equipped with the hole, the hole penetrates fixed reinforcement and foundation ditch top is fixed.
In a preferred embodiment of the invention, the rungs are horizontally slidingly connected with the hollow ladder column.
In a preferred embodiment of the invention, telescopic struts are arranged vertically between the rungs.
In a preferred embodiment of the invention, the rungs are provided with foot recesses at both ends.
In a preferred embodiment of the invention, a rotating shaft is connected between the extension ladders, so that the purpose that the extension ladders can be folded is achieved.
The beneficial effects of the invention are as follows: according to the invention, the whole structure is tightly combined with the bottom of the foundation pit and the top of the foundation pit through the fixation of the ladder base and the ladder top, the ladder is safe and reliable, the vertical distance between the ladder steps can be randomly adjusted through the sliding connection of the ladder steps, the telescopic rods and the hollow ladder columns, the use is more convenient, the whole ladder is more stable and difficult to bend in the vertical direction through the action of the anti-bending steel bars, and the whole structure is more easily detached and placed through the rotation connection between the extension ladders. Meanwhile, the whole structure is detachable, so that parts are convenient to replace and clean, and the service life is prolonged.
