Technical Field
The utility model relates to the technical field of road construction, in particular to a highway bridge construction foundation pit protection device.
Background
Along with the development of the times, the living standard of people is continuously improved, and in order to improve the economic development condition of cities, more and more highway bridges are built, and excavation of foundation pits is often needed when the highway bridges are built. The foundation pit is a soil pit excavated at the design position of the foundation according to the elevation of the foundation and the plane size of the foundation. In the excavation construction of the foundation pit, the danger that the outer side soil layer collapses and the foundation pit collapses due to precipitation and underground water is prevented, so certain protective measures need to be taken.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a highway bridge construction foundation pit protection device to solve the problems in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme: a highway bridge construction foundation pit protection device comprises a drainage ditch arranged on the bottom surface of a foundation pit, wherein a slope protection hanging net is arranged on the surface of a foundation pit side slope, an anchor rod which obliquely and downwards extends into the interior of earthwork is drilled on the foundation pit side slope, a plurality of groups of steel pipe supports are horizontally arranged in the foundation pit, and two ends of each steel pipe support are supported on the surface of the foundation pit side slope;
a guardrail is arranged around the upper opening of the foundation pit, and a water intercepting ditch is formed in the outer side of the guardrail.
Preferably, the two ends of the steel pipe support are fixedly connected with wood wedges, and the inclined surfaces of the wood wedges are in abutting fit with the surface of the foundation pit side slope.
Preferably, the distance between the guardrail and the side opening of the foundation pit is not less than 50 cm.
Preferably, the anchor rod is a full-adhesion type anchor rod and has an included angle of 15 degrees with the horizontal line.
Preferably, the slope protection hanging net is sprayed with a concrete slope protection as a framework.
Has the advantages that: compared with the prior art, the utility model has the beneficial effects that: through the arrangement of the drainage ditch and the intercepting ditch, precipitation and underground water are effectively prevented from being gathered in the foundation pit, and the foundation pit is prevented from collapsing due to water erosion; through the arrangement of the slope protection hanging net, the anchor rod and the steel pipe support, the stability of the foundation pit side slope is effectively guaranteed, and the outer side soil layer is prevented from collapsing into the foundation pit due to large soil pressure.
