Problems solved by technology
[0004] In view of this, the present invention provides a foundation pit protective device for road and bridge construction, which has a top cover, and when the two top covers are flipped and closed, they can form a common fence with the four side rails and the thin aluminum plates on the two side rails. It is located in a relatively closed space to solve the problem that the protective device cannot block the rainwater, which causes water to enter the foundation pit in rainy days

Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0024] see Figure 1 to Figure 8 ;
[0025] The present invention proposes a foundation pit protective device for road and bridge construction, comprising: a side guardrail 1; the side guardrail 1 includes a vertical support pipe 101, and the side guardrail 1 is composed of two left and right vertical support pipes 101 welded to two vertical supports The two horizontal support square tubes at the upper and lower ends of the branch pipe 101 and the thin aluminum plate welded between the two vertical support pipes 101 are composed together; the side guardrail 1 is symmetrically arranged at two places, and four vertical support pipes 101 are rotated and installed at fou...

The invention discloses a foundation pit protection device for road and bridge construction, and relates to the technical field of construction protection devices. The whole side guardrail is jointly composed of a left vertical supporting branch pipe, a right vertical supporting branch pipe, two transverse supporting square pipes welded to the upper ends and the lower ends of the two vertical supporting branch pipes, and a thin aluminum plate welded between the two vertical supporting branch pipes in a blocking mode. The two side guardrails are symmetrically arranged, and four side breast boards are rotationally mounted on four vertical supporting pipes; and two top covers are oppositely and rotationally installed on two transverse supporting square pipes at the top ends of the two side guardrails, four sets of transverse supporting positioning shafts are symmetrically welded to the top end sections of four vertical supporting branch pipes, and the four sets of transverse supporting positioning shafts are each slidably sleeved with a sliding part. When the two top covers are turned over and closed, the two top covers, the four side breast boards and the thin aluminum plates on the two side guardrails form a relatively closed space which can be used as a rain shelter for operation in rainy days, the function of the protection device is expanded, and the problem that the function of the protection device is single is solved.
Description
technical field [0001] The invention relates to the technical field of construction protection devices, in particular to a foundation pit protection device for road and bridge construction. Background technique [0002] The implementation of road and bridge projects requires digging foundation pits. Foundation pits are excavated at the foundation design position according to the base elevation and foundation plane size. In order to prevent pedestrians from entering the foundation pit by mistake and causing safety accidents, foundation pit protection is required. Device prevents and reminds pedestrians, and this just needs to use a kind of excavation protection device that road and bridge construction is used. [0003] Most of the existing foundation pit protection devices lack auxiliary rain-shielding panels, and the rain-shielding effect is not good, resulting in serious water ingress in the foundation pit in rainy days, resulting in troublesome subsequent cleaning of accum...
