Description

Technical Field

[0001] This utility model relates to the technical field of diversion devices, specifically a rainwater diversion device for foundation pit support construction. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the foundation elevation and foundation plane dimensions. Excavation pit support is a set of measures to support, reinforce and protect the side walls and surrounding environment of the excavation pit in order to ensure the safety of underground structure construction and the surrounding environment.

[0003] In the prior art, Chinese Patent No. CN220666237U discloses a construction pit support device, which includes "a support plate, the front of which is fixedly connected to the rear end of a support base, the upper end of which is fixedly connected to the lower end of a limiting block, the upper end of which is fixedly connected to the lower end of a connecting base, the upper end of a movable arm slidably connected to the lower end of a docking plate, the lower end of which is fixedly connected to the upper end of a slider, the upper end of which is fixedly connected to the lower end of a support arm, and a threaded connection between the upper end of a connecting plate and the lower end of a fixing bolt." The design features a screw-on connection between the lower end of the connecting plate and the tightening bolt, a screw-on connection between the back of the support plate and the front of the fixed base, a screw-on connection between the upper end of the fixed base and the lower end of the limiting rod, and a screw-on connection between the back of the support plate and the upper end of the support column. Since the back of the support plate also has a fixing mechanism, the stability of the device can be further improved.

[0004] However, the above solution still has some shortcomings. For example, in actual use, during rainy weather, rainwater will flow along the surface of the support plate into the pit, causing the water level in the pit to rise. That is, the technical solution proposed by the above patent technology has the defect of not being able to fully drain rainwater.

[0005] In view of this, the present invention proposes a rainwater diversion device for foundation pit support construction. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] According to the appendix Figure 1-5 As shown in the figure, this utility model embodiment provides a rainwater diversion device for foundation pit support construction, including,

[0035] Support plate 100, which is used to support the inner wall of the foundation pit;

[0036] The flow guiding component 200 is used to guide and collect rainwater. The flow guiding component 200 includes a plurality of flow guiding channels 201 equidistantly opened on the surface of the support plate 100, and a water storage tank 202 disposed at the bottom of the support plate 100. The upper surface of the water storage tank 202 is provided with a rectangular opening, and a first intercepting mesh plate 203 is fixedly provided on the inner wall of the rectangular opening, which can intercept and filter debris in the rainwater.

[0037] The flow guiding assembly 200 also includes a flow guiding plate 204 fixed at the top of the support plate 100 for insertion into the inner wall of the pit, and a limiting plate 205 fixed at the top of the support plate 100 corresponding to the flow guiding plate 204. The upper surface of the support plate 100 is provided with a strip-shaped collection groove 206, and the inner wall of the strip-shaped collection groove 206 is fixed with a second intercepting mesh plate 207, which can intercept and filter sand and gravel.

[0038] The inner top wall of several diversion channels 201 is provided with diversion holes 209 extending into the strip collection channel 206, and the bottom of the diversion channel 201 is a sloping structure to facilitate the diversion of rainwater.

[0039] A limiting frame 208 for limiting rainwater is fixed on the upper surface of the water storage tank 202 and the front of the support plate 100 to prevent rainwater from flowing out of the water storage tank 202 to the bottom of the pit.

[0040] In this embodiment, by setting the flow guiding component 200, during the process of the device supporting the inside of the foundation pit through the support plate 100, rainwater can be guided to the inside of the water storage tank 202 through the flow guiding channel 201 during rainy weather. At the same time, the setting of the flow guiding insert plate 204 on the top of the support plate 100 can prevent rainwater from seeping into the inside of the foundation pit from the top of the foundation pit. The rainwater is collected by the strip collection channel 206, and then enters the flow guiding channel 201 through the flow guiding hole 209, and finally enters the water storage tank 202 for collection. This effectively avoids the situation where rainwater directly enters the inside of the foundation pit through the inside of the foundation pit, causing the water level in the foundation pit to rise. Thus, it effectively solves the defect of the prior art that cannot fully guide rainwater.

[0041] Example 2

[0042] Based on Example 1, and differing from Example 1 in that,

[0043] A rainwater diversion device for foundation pit support construction also includes,

[0044] The discharge component 300 is used to discharge rainwater when it reaches a certain amount inside the water storage tank 202.

[0045] The discharge assembly 300 includes a water pump 301 fixed to the bottom wall of the water storage tank 202, and the water pump 301 is provided with a filter cover 302 at the water inlet end. The water pump 301 extends to the outer surface of the water storage tank 202 and is fixed with a drainage hose 303 extending to the outside of the pit, so as to facilitate the discharge of rainwater in the water storage tank 202.

[0046] The discharge assembly 300 also includes a fixing rod 304 fixed to the top and bottom walls of the water storage tank 202, and a float 305 slidably disposed on the surface of the fixing rod 304.

[0047] The inner wall of the water storage tank 202 is respectively fixed with a high water level contact sensor 306 and a low water level contact sensor 307 corresponding to the float 305.

[0048] A mounting bracket is fixed to the side of the water storage tank 202, and a control cabinet 308 is fixed to the top of the mounting bracket. A PLC controller 309 is installed inside the control cabinet 308, and the water pump 301, the high water level contact sensor 306 and the low water level contact sensor 307 are all electrically connected to the PLC controller 309 through wires.

[0049] In this embodiment, by setting up the discharge component 300, when the amount of rainwater in the water storage tank 202 increases, it can drive the float 305 to move upward. When the float 305 contacts the high water level contact sensor 306, the high water level contact sensor 306 transmits a signal to the PLC controller 309. The PLC controller 309 automatically controls the water pump 301 to start, and discharges the water in the water storage tank 202 to the outside of the pit through the drain hose 303. When the water level drops to the position of the low water level contact sensor 307, the float 305 contacts the low water level contact sensor 307. At this time, the low water level contact sensor 307 transmits a signal to the PLC controller 309. The PLC controller 309 automatically controls the water pump 301 to shut down, thereby achieving the purpose of automatically discharging the rainwater collected in the water storage tank 202, which is highly practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
