Abstract
Description
Technical Field
[0001] This utility model relates to the field of groundwater diversion technology, specifically a groundwater diversion structure. Background Technology
[0002] In underground engineering construction, excessive accumulation of groundwater may increase the instability of the geological structure, thereby triggering geological disasters. Therefore, before underground engineering construction, it is necessary to conduct detailed investigation and analysis of groundwater level, water quality, flow direction, etc., and then discharge groundwater in a timely manner through diversion structures to reduce construction risks and ensure the safety and stability of underground engineering.
[0003] Existing groundwater diversion structures typically involve burying perforated drainage pipes beneath the rock layer during construction, allowing groundwater to flow out through the gaps in the rocks. However, considering that most drainage pipes are made of polyethylene and the rock layer is quite hard, if the rock layer is subjected to prolonged vehicle traffic pressure without adequate reinforcement, the buried drainage pipes may break or be damaged due to constant pressure. This can lead to obstructed groundwater flow and hinder the normal groundwater diversion function of the entire structure. Therefore, a new groundwater diversion structure is proposed to address these issues. Utility Model Content
[0004] The purpose of this utility model is to provide a groundwater diversion structure to solve the problem mentioned in the background art that the existing groundwater diversion structure, when in use, is prone to breakage and damage due to long-term pressure from vehicles when the drainage pipe buried under the rock layer is subjected to pressure.

[0006] A groundwater diversion structure includes a foundation soil layer, a stone chip cushion layer on top of the foundation soil layer, a stone block layer on top of the stone chip cushion layer, a metal mesh sleeve between the stone block layer and the stone chip cushion layer, a drainage pipe inside the metal mesh sleeve, an inner insertion pipe inside the drainage pipe, a first drainage hole on the outer surface of the drainage pipe, metal protrusions fixedly connected to the outer top, bottom, left and right sides of the metal mesh sleeve, and connecting short columns fixedly connected to the upper right and lower right sides of the inner insertion pipe, with the connecting short columns fixedly connected to the metal mesh sleeve.
[0007] Preferably, a manifold is provided on the right side of the foundation soil layer, and the outlet ports of the metal mesh sleeve, the diversion pipe, and the inner insertion pipe extend into the manifold.
[0008] Preferably, a road surface is provided above the stone layer, and the thickness of the stone layer is greater than the thickness of the stone chip layer.
[0009] Preferably, the outer surface of the inner tube is provided with a second guide hole, the diameter of the second guide hole is smaller than the diameter of the first guide hole, and the outer surface of the inner tube is provided with a sealing ring that fits together with the inner surface of the drainage tube, the sealing ring being located on the left side of the connecting short column.
[0010] Preferably, the inner diameter of the metal mesh sleeve is equal to the outer diameter of the drainage tube, the metal protrusion is in the shape of a pointed cone, the gap between the metal mesh sleeve and the inner tube matches the thickness of the drainage tube, and the right side of the drainage tube is provided with a slot structure that engages with the connecting short post.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, the metal mesh sleeve, metal protrusions, inner tube, connecting short column, and sealing ring facilitate the use of the groundwater diversion structure between the stone chip layer and the rock layer for diversion. Before use, the inner and outer tube reinforcement structure, consisting of the metal mesh sleeve, metal protrusions, inner tube, connecting short column, and sealing ring, is installed on the diversion pipe in a nested configuration.

[0018] 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.
[0019] Please see Figure 1-4 This utility model provides a technical solution:
[0020] A groundwater diversion structure includes a base soil layer 1, a stone chip cushion layer 3 covering the base soil layer 1, a stone block layer 12 covering the stone chip cushion layer 3, a metal mesh sleeve 4 between the stone block layer 12 and the stone chip cushion layer 3, a drainage pipe 6 inside the metal mesh sleeve 4, an inner insertion pipe 7 inside the drainage pipe 6, a first diversion hole 11 on the outer surface of the drainage pipe 6, metal protrusions 5 fixedly connected to the outer top, bottom, left and right sides of the metal mesh sleeve 4, and connecting short columns 8 fixedly connected to the upper right and lower right sides of the inner insertion pipe 7, respectively, and the connecting short columns 8 are fixedly connected to the metal mesh sleeve 4.
[0021] like Figure 1 As shown, a manhole 2 is provided on the right side of the subgrade layer 1. The outlet ports of the metal mesh sleeve 4, the diversion pipe 6, and the inner pipe 7 extend into the manhole 2. The manhole 2 is mainly used to collect groundwater. A road surface 13 is provided above the stone layer 12. The thickness of the stone layer 12 is greater than the thickness of the stone chip cushion layer 3. When constructing the entire diversion structure, the stone chip cushion layer 3 is mainly used to increase the stability and bearing capacity of the road surface 13.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer surface of the inner tube 7 is provided with a second guide hole 10, the diameter of which is smaller than that of the first guide hole 11. The outer surface of the inner tube 7 is provided with a sealing ring 9 that fits together with the inner surface of the drainage tube 6. The sealing ring 9 is located on the left side of the connecting short column 8. When groundwater is introduced into this drainage structure, the second guide hole 10 and the first guide hole 11 can play a multi-stage filtration role. The inner diameter of the metal mesh sleeve 4 is equal to the outer diameter of the drainage tube 6. The metal protrusion 5 is in the shape of a pointed cone. The gap formed between the metal mesh sleeve 4 and the inner tube 7 matches the thickness of the drainage tube 6. The right side of the drainage tube 6 is provided with a groove structure that engages with the connecting short column 8. When the drainage tube 6 is squeezed by stones, the metal protrusion 5 can enhance the overall strength of the metal mesh sleeve 4.
[0023] Workflow: Before use, the flow guiding structure of this utility model needs to be embedded between the stone chip cushion layer 3 and the stone block layer 12. Then, around the outlet port of the flow guiding structure, a confluence well 2 is pre-cast in the base soil layer 1 using concrete. Specifically, when the flow guiding structure needs to be embedded between the stone chip cushion layer 3 and the stone block layer 12, an appropriate amount of stone chips constituting the stone chip cushion layer 3 are spread evenly on the base soil layer 1, such as... Figure 3 and Figure 4 As shown, before laying the stones, the drainage pipe 6 is inserted into the gap formed between the metal mesh sleeve 4 and the inner tube 7. The metal mesh sleeve 4, the drainage pipe 6, and the inner tube 7 form a triple sleeve structure. This triple sleeve structure is then placed horizontally on the stone chip cushion layer 3, and stones are laid on top, so that the triple sleeve structure is buried between the stone chip cushion layer 3 and the stone layer 12. When the engineering vehicle drives to the vicinity of the groundwater diversion structure and compresses the stone layer 12, the connection of the short column 8 limits the flow. The inner and outer tube reinforcement structure, consisting of a metal mesh sleeve 4, metal protrusions 5, inner tube 7, connecting short column 8, and sealing ring 9, can strengthen the drainage pipe 6 from both the inside and outside, preventing the drainage pipe 6 from being damaged or cracked due to long-term pressure from the rock layer 12. At the same time, when groundwater seeps into the area below the rock layer 12, the groundwater will pass through the interior of the metal mesh sleeve 4, the first guide hole 11, and the second guide hole 10, and be concentrated into the inner tube 7, and finally sent into the interior of the confluence well 2 for collection, so that it can be used in subsequent projects.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
