[0002] The foundation pit is a pit dug at the design location of the foundation according to the base elevation and the plane size of the foundation. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the slope can be used to stabilize the slope, and the slope size is determined according to relevant construction regulations. For deep excavations and nearby buildings, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing; if there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and use slope open excavation; in cold areas, natural cold air freezing method can be used for excavation, etc.

[0003] The foundation pit is a temporary project, and its function is to provide a space so that the foundation masonry work can be carried out according to the position specified by the design. The existing foundation pit needs to be fenced when it is excavated. During the excavation and later processing of the existing foundation pit, it is easy for road water flow and debris to enter the foundation pit, which has a great impact on the working environment of the foundation pit and even causes collapse. Therefore, it is necessary to provide a foundation pit fence device to prevent road water flow. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Example 1

[0026] A foundation pit fence device for preventing water flow on the road surface comprises a plurality of detachably connected fences 2, wherein the fence 2 comprises a pair of columns 21 and a frame 22 arranged in the pair of columns 21, a plurality of railings 23 are arranged in the frame 22, and a protective net 24 is arranged between the plurality of railings 23; a water intercepting groove 3 is arranged in the horizontal direction at the bottom of the frame 22, and the water intercepting groove 3 is connected to a sewer through a pipe; two adjacent frames 22 are detachably connected by a connecting piece.

[0027] Specifically: the utility model fence 2 device uses the bottom of the column 21 to be inserted into the ground for fixing until the bottom of the frame 22 is flush with the ground. At this time, the intercepting groove 3 at the bottom of the frame 22 is located at the ground level. If there is water flowing on the road surface, it can be intercepted by the intercepting groove 3 and directly flow into the intercepting groove 3. Then the water in the intercepting groove 3 can be sent to the sewer pipe through the pipe; in addition, a intercepting groove 3 can also be set on the side of the frame 22 close to the foundation pit 1, so that the road water flow can be double intercepted to prevent water from flowing into the foundation pit 1; at the same time, in order to maintain the overall stability of the fence 2 and the filtering effect of debris to maintain the working environment in the foundation pit 1, the utility model is provided with a protective net 24 between the railings 23 in the frame 22. On the one hand, the protective net 24 can be used to intercept debris, and on the other hand, the overall weight of the fence 2 can be reduced, and the installation is more convenient. At the same time, in order to maintain the connection stability and convenience between the fences 2, especially the connection stability of the fence 2 at the corner of the foundation pit 1, the adjacent two frames 22 of the utility model are detachably connected by a connector.

[0028] Specifically, the connecting member includes a plurality of first connecting plates 25 arranged on one side of the frame 22 and a plurality of second connecting plates 26 arranged on the other side of the frame 22, and the plurality of fences 2 are connected end to end in sequence through the first connecting plates 25 and the second connecting plates 26 between two adjacent frames 22; more specifically, a limiting groove 251 is horizontally provided on the side of the first connecting plate 25 away from the frame 22, and a positioning hole 252 is longitudinally provided, and the positioning hole 252 passes through the limiting groove 251; a limiting hole 261 is provided on the side of the second connecting plate 26 away from the frame 22, and the side of the second connecting plate 26 away from the frame 22 can be extended into the limiting groove 251, and after the second connecting plate 26 is extended into the limiting groove 251, the limiting hole 261 and the positioning hole 252 are coaxially arranged. Insert one end of the second connecting plate 26 into the limiting groove 251. At this time, the limiting hole 261 and the positioning hole 252 are set correspondingly. Then, the positioning shaft pin can be used to penetrate the limiting hole 261 and connect with the positioning hole 252. If encountering the corner of the edge of the foundation pit 1, one end of the second connecting plate 26 can be adaptively rotated in the limiting groove 251 of the first connecting plate 25 to adjust the connection angle between the first connecting plate 25 and the second connecting plate 26, so that the two fences 2 can be adaptively adjusted according to the outer contour of the foundation pit 1 to maintain the protective effect on the foundation pit 1.

[0029] In this embodiment, the side of the second connecting plate 26 away from the frame 22 is arc-shaped, so that the end of the second connecting plate 26 can be more stably rotated in the limiting groove 251, while keeping the limiting hole 261 corresponding to the positioning hole 252, thereby more stably adjusting the connection degree between the first connecting plate 25 and the second connecting plate 26.

[0030] In this embodiment, a support plate 5 is hinged on one side of the frame 22 close to the foundation pit 1. The support plate 5 is inclined relative to the frame 22, and the bottom of the support plate 5 is adjacent to the bottom surface. Preferably, the width of the support plate 5 is the same as that of the frame 22. This not only supports the fence 2 to maintain its stability, but also further blocks the water flow on the road surface.

[0031] In this embodiment, a flange 6 is provided on the bottom surface of the support plate 5 , and the flange 6 is connected to the ground through anchor nails.

[0032] In this embodiment, a filter plate 4 is provided on the top of the intercepting groove 3, so that impurities on the road surface can be filtered to a certain extent, thereby preventing the road water flow from carrying debris into the intercepting groove 3 and causing blockage.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
