[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] like Figs. 1 to 4 As shown, a preferred embodiment of this utility model provides a deep foundation pit rainproof device, which has a first direction and a second direction that intersect perpendicularly, including a first column 1, a second column 2 and a drainage component 3. The first column 1 and the second column 2 are symmetrically arranged on both sides of the deep foundation pit along the first direction.

[0025] The drainage component 3 includes a motor 31, a traction rope 32, and a folded tarpaulin 33; the motor 31 is mounted on the first column 1 or the second column 2, and the output end of the motor 31 is connected to the folded tarpaulin 33 through the traction rope 32. The end of the folded tarpaulin 33 away from the motor 31 is fixed to the second column 2 or the first column 1.

[0026] A counterweight 34 is provided in the middle of the end of the folded tarpaulin 33 away from the motor 31.

[0027] Specifically, in the past, when encountering heavy rain, there was often no effective way to deal with the continuous accumulation of rainwater in the deep foundation pit. The only option was to use pumps to continuously remove the water from the deep foundation pit, which was not only time-consuming and labor-intensive, but the accumulated water would also damage the soil structure of the deep foundation pit, creating safety hazards. After the weather cleared up, it was necessary to wait for the soil in the deep foundation pit to dry before subsequent construction could proceed, which seriously slowed down the construction efficiency of the project. In this application, a drainage component 3 is installed above the deep foundation pit. In sunny weather, the folded tarpaulin 33 is retracted, not affecting subsequent construction of the deep foundation pit. During heavy rain, a motor 31 is activated, driving a traction rope 32 to unfold the folded tarpaulin 33, covering the deep foundation pit and preventing rainwater from dripping and accumulating inside. Furthermore, a counterweight 34 at the center of one end of the folded tarpaulin 33 forms a guide channel and opening on the unfolded tarpaulin. Rainwater falling on the tarpaulin 33 moves along the guide channel and is discharged through the opening to the outside of the deep foundation pit, preventing rainwater from flowing back into the pit from around the tarpaulin 33, further preventing rainwater accumulation within the pit. In fact, a pumping pipe can be installed at the opening of the folded tarpaulin 33 to fill all the rainwater on the tarpaulin 33 into a dug well, preventing rainwater from dripping around the deep foundation pit.

[0028] In some embodiments, the drainage assembly 3 is provided with two in the first direction symmetrically on both sides of the deep foundation pit. Specifically, when facing a deep foundation pit with a relatively long length, the area of the single folding rain cloth 33 is too large to be unfolded, and too much rainwater can be accumulated in the guide channel. The folding rain cloth 33 is difficult to withstand the pressure of too much rainwater, and the rainwater in the guide channel is prone to flow into the deep foundation pit, causing water accumulation in the deep foundation pit. In addition, the folding rain cloth 33 is difficult to use and transfer due to its large size, and the entire unfolding process is more complex and difficult. Therefore, two folding rain cloths 33 are provided in the utility model to cooperate with each other, so as to form a conical structure similar to a roof, thereby sharing the pressure of the rainwater and realizing the diversion of the rainwater above the deep foundation pit, reducing the guide pressure of the folding rain cloth 33, and the rainwater can be drained away more quickly and smoothly.

[0029] In some embodiments, the first column 1 and the second column 2 are each provided with two in the second direction, the two motors 31 are arranged in the second direction, and the two traction ropes 32 are each arranged in the first direction. The staggered arrangement of the two motors 31 and the two traction ropes 32 can avoid structural interference, and the two folding rain cloths 33 can be unfolded and connected synchronously, thereby avoiding rainwater from falling into the deep foundation pit. Of course, in another embodiment, the two ends of the two single folding rain cloths 33 can be provided with traction ropes 32 and clicks, so that the folding rain cloth 33 can be unfolded more quickly and smoothly.

[0030] In some embodiments, the folding rain cloth 33 comprises a cloth body 331 and an extension arm 332, the extension arm 332 is arranged at the side of the cloth body 331, and the end thereof is fixedly connected with the traction rope 32. The extension arm 332 comprises a plurality of extension rods 3321 connected movably. The extension rods 3321 in the extension arm 332 can be provided in multiple numbers according to the size of the actual cloth body 331. In the folded state of the folding rain cloth 33, the adjacent extension rods 3321 are also in the folded state. When the folding rain cloth 33 needs to be unfolded, the adjacent extension rods 3321 are unfolded, so that the cloth body 331 is opened to cover the deep foundation pit. In a specific embodiment, the adjacent extension rods 3321 are rotatably connected.

[0031] In some embodiments, the extension arm 332 further comprises a water delivery pipe 35, the water delivery pipe 35 is fixedly connected with the extension rod 3321, and the water delivery pipe 35 is connected with a spray head 36. Further, the middle part of the extension rod 3321 is provided with a through hole 37, the water delivery pipe 35 is sleeved in the through hole 37, and the extension rod 3321 is arranged at the spray opening corresponding to the spray head 36. The water delivery pipe 35 and the spray head 36 are arranged to spray mist into the deep foundation pit in dry weather in summer, thereby cooling the construction environment in the deep foundation pit. At the same time, the folding rain cloth 33 can avoid direct sunlight into the deep foundation pit, and the spray head 36 is combined, thereby improving the construction environment in the deep foundation pit.

[0032] In some embodiments, both ends of the stretching rod 3321 are provided with an inlet and an outlet, the inlet is used to introduce the water pipe 35, and the outlet is used to lead out the water pipe 35. The arrangement of the inlet and the outlet facilitates the installation and transfer of the water pipe 35 in the stretching rod, and also facilitates the installation and disassembly of the water pipe 35.

[0033] In some embodiments, a reset spring 38 is arranged between adjacent stretching rods 3321, both ends of the reset spring 38 are fixedly connected with the adjacent two stretching rods 3321, and the reset spring 38 is used to reset the adjacent two stretching rods 3321. In a specific embodiment, the reset spring 38 can adopt a torsion spring, so that the adjacent stretching rods 3321 can be automatically reset and folded under the action of no other external force. In particular, when the motor 31 no longer applies a traction force to the traction rope 32, the reset spring 38 can push the stretching rod 3321 to reset and fold, and complete the automatic storage of the folding rain cloth 33. In another embodiment, the reset spring 38 can also adopt a tension spring, when the stretching rod 3321 is unfolded, the reset spring 38 is compressed or pulled open, when the motor 31 no longer applies a traction force, the reset spring 38 drives the stretching rod 3321 to reset and fold. In fact, when the reset spring 38 uses a tension spring structure, it can also be directly arranged on the outside of the stretching rod 3321, and does not necessarily be arranged in the through hole 37.

[0034] In some embodiments, the first column 1 and the second column 2 are both provided with a recovery rope 39, and the recovery rope 39 is used to bind and fix the stretching arm 332. The recovery rope 39 can limit the position structure of the stretching arm 332, avoid the influence of the swinging of the stretching arm 332 when not in use, and avoid safety hazards.

[0035] In summary, the deep foundation pit rainproof device provided by the embodiment of the utility model can guide and discharge rainwater outside the deep foundation pit through the folding rain cloth 33 in rainy weather, avoid the accumulation of rainwater in the deep foundation pit, and affect the construction progress and safety. In sunny weather, the environment in the deep foundation pit can be improved and cooled through the water pipe 35 and the spray head 36, and the construction environment can be avoided from being too harsh.

[0036] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary technical personnel in the technical field, without departing from the technical principle of the utility model, a number of improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection range of the utility model.
