Description

Technical Field

[0001] The invention belongs to a soil permeable stratum dewatering device, and in particular relates to a spider web folding vacuum dewatering device for extremely permeable strata. Background Art

[0002] At present, the main methods for dewatering the bottom layer of soil with strong permeability include pipe well dewatering, large-diameter pumping and seepage well dewatering. Since pipe well dewatering will cause the groundwater level outside the pit to drop, it may cause the consolidation and sinking of the soil around the stratum, which will have a certain impact on the surrounding environment, so it is not suitable; and large-diameter pumping may affect the groundwater environment and affect the balance of groundwater resources, and the construction and maintenance costs of large-diameter are high, and the technical requirements are also higher. In addition, it may cause geological disasters such as ground collapse, so it is not suitable for large-scale applications; seepage well dewatering will affect the stability of underground space devices, thereby causing foundation settlement, thereby affecting the construction progress, and it may also damage the soil device, causing soil compaction and affecting crops. Therefore, whether from the perspective of the environment or the construction progress, this method is also inappropriate. Therefore, in order to solve the problems of uneven pumping pressure, easy collapse, and impact on the water environment, this application creatively proposes a spider web vacuum dewatering device for extremely permeable strata of soil.

[0003] Regarding the above-mentioned related technologies, traditional precipitation methods may cause the groundwater level to drop, the formation to settle, and even cause ground collapse when performing stratum precipitation. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art and to be able to effectively pump out water in extremely permeable formations without the above-mentioned shortcomings caused by pumping water, the present invention provides a spider web folding vacuum dewatering device for extremely permeable formations.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A spider web folding vacuum dewatering device for extremely permeable strata comprises a spider web righting tower, a rod, a spider web dewatering mechanism, a high-pressure pipe, a vacuum plunger pump and a water reservoir, wherein the spider web righting tower, the vacuum plunger pump and the water reservoir are located on the surface of the water-rich strata, the rod is liftably mounted on the web righting tower, the lower end of the high-pressure pipe extends into the inner cavity of the rod, the upper end of the high-pressure pipe is connected to the water reservoir via the vacuum plunger pump, and the spider web dewatering mechanism is arranged at the lower end of the rod.

[0007] Furthermore, the spider web water-reducing mechanism includes a telescopic rod, a first water suction pipe, a second water suction pipe and a latch, the upper end of the telescopic rod is hinged to the lower end of the rod, at least three telescopic rods are equally spaced in a circle at the lower end of the rod, at least two sets of first water suction pipes and second water suction pipes are hinged on both sides of the telescopic rod from top to bottom, the first water suction pipe of one telescopic rod is rotatably connected to the second water suction pipe of the adjacent telescopic rod through a latch, the first water suction pipe and the second water suction pipe are both provided with water inlets and are both connected to the middle of the telescopic rod, and the upper end of the telescopic rod is connected to the inner cavity of the rod. In this scheme, the size of each set of first water suction pipes and second water suction pipes gradually increases from top to bottom, forming a spider web structure.

[0008] Preferably, there are eight telescopic rods, and three sets of first water suction pipes and second water suction pipes are hingedly connected to two sides of the telescopic rods from top to bottom.

[0009] More preferably, the first water suction pipe and the second water suction pipe are variable diameter pipes.

[0010] More preferably, the upper end of the telescopic rod is connected to a ball bearing, and the ball bearing is rollably located at the lower end of the rod, that is, the ball bearing is arranged at the lower end of the rod to play a hinge role.

[0011] Furthermore, a cone head is provided at the middle of the lower end of the rod, and a strength sensor is provided at the lower end of the cone head.

[0012] Furthermore, a spider web type water level sensor is disposed on the outer shell of the rod, and a baffle is disposed outside the spider web type water level sensor.

[0013] The beneficial effects of the present invention are mainly manifested in:

[0014] 1. A spider web precipitation mechanism is set up to increase or reduce the precipitation rate of the stratum; each of the spider web precipitation mechanisms is provided with eight connecting parts, and each connecting part is connected by a suction pipe in the middle, and the suction pipe can be appropriately adjusted according to the change of water level.

[0015] 2. Independent spider-web water level sensors are installed in the spider-web pipe network, and the sensors can work independently based on the detected situation. Sensors in different areas can monitor the actual water level and soil permeability to independently adjust the working intensity, ensuring that the pumping force is increased in areas with strong permeability, while the pumping force is reduced in areas with weak permeability. This can avoid energy waste in the entire system and improve precipitation efficiency;

[0016] 3. A strength sensor is also set at the lower end of the rod to monitor the moisture changes and pressure status of the surrounding soil layer; and the rod shell can be embedded with a water level sensor to obtain the groundwater level changes in real time. This double-layer design can not only improve the stability of the pipeline, but also provide real-time environmental data for the precipitation process to help adjust the precipitation strategy;

[0017] 4. The suction pipe is designed as a variable diameter pipe, that is, the pipe diameter can be adjusted automatically or manually according to the groundwater level and soil permeability. In areas with high groundwater levels, the pipe diameter is increased to improve pumping efficiency; in areas with low permeability or less water, the pipe diameter is reduced to avoid energy waste or soil depletion caused by excessive pumping. This design can dynamically adapt to precipitation needs under different geological conditions. BRIEF DESCRIPTION OF THE DRAWINGS
