Description

Technical Field

[0001] This application relates to the field of building engineering technology, and in particular to a novel concrete drainage structure. Background Technology

[0002] In building construction, drainage systems are important external drainage facilities used to prevent rainwater from seeping into the foundation, thus protecting the building's foundation. Traditional drainage systems are mostly made of poured concrete or brick masonry, which are simple in design but suffer from problems such as low drainage efficiency and susceptibility to cracking.

[0003] Currently, common drainage structure solutions include the following: First, cast-in-place concrete drainage, which has the advantages of high strength and low cost, but has a long construction period and is prone to cracking; second, precast concrete slab drainage, which has a fast construction speed, but is prone to water seepage at the joints; and third, polymer material drainage, which is lightweight and corrosion resistant, but has a high cost and insufficient compressive strength.

[0004] The main drawbacks of existing drainage structures include: low drainage efficiency and easy water accumulation; poor freeze-thaw resistance, which makes them prone to cracking and peeling after long-term use; complex construction, especially for precast and polymer material drainage structures; and high cost, making it difficult to promote on a large scale. Therefore, this application proposes a new type of concrete drainage structure to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a novel concrete drainage structure that overcomes the deficiencies of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: a novel concrete drainage structure, comprising a base layer and a precast slab, wherein a drainage layer is installed on top of the base layer, a surface layer is installed on top of the drainage layer, geotextile is laid on top of the base layer, and a permeable pipe is installed on top of the drainage layer.

[0007] In a preferred embodiment, the base layer can be replaced with a precast panel, which is connected by a rubber sealing strip.

[0008] By adopting the above technical solutions, the construction speed and joint waterproofing performance can be improved, and compatibility can be guaranteed.

[0009] In a preferred embodiment, the top of the surface layer is provided with a slope that slopes outward toward the outside of the building.

[0010] By adopting the above technical solution, water can be quickly discharged to the outside of the building.

[0011] In a preferred embodiment, the geotextile is disposed between the base layer and the drainage layer, and four pins are symmetrically inserted into the inner wall of the geotextile, with the pins extending to the inner wall of the base layer.

[0012] By adopting the above technical solution, geotextiles can be used to prevent soil particles from clogging the drainage layer, and pins can be used to position the geotextiles, ensuring their stability and preventing them from easily detaching from the top of the base layer.

[0013] In a preferred embodiment, there are multiple permeable pipes, which are evenly distributed in the middle of the drainage layer and the surface layer.

[0014] By adopting the above technical solution, the permeable pipe can guide water into the drainage layer, and the use of multiple drainage layers can ensure the thoroughness of water guidance.

[0015] In a preferred embodiment, the permeable pipe is a PVC porous pipe with a diameter of 100mm.

[0016] By adopting the above technical solutions, its durability can be guaranteed, ensuring that it will not be easily damaged after long-term use.

[0017] In a preferred embodiment, the geotextile is made of polypropylene, the drainage layer is graded crushed stone with a particle size of 5-20mm, and the base layer is a compacted soil foundation.

[0018] By adopting the above technical solutions, geotextiles, as impermeable layers, can isolate seepage water from different soil layers, protect the stability of the roadbed structure, and reduce the erosion of materials by water.

[0019] The beneficial effects of this application are:

[0020] This new type of concrete drainage structure achieves high drainage efficiency by setting up a drainage layer, surface layer, slope, geotextile and permeable pipes. It can effectively prevent water accumulation and has good freeze-thaw resistance. It is not easy to crack and peel off after long-term use. At the same time, it is easy to construct, low in cost, easy to promote on a large scale, and has strong structural durability, thus extending the service life of buildings.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Reference Figure 1-3 A novel concrete drainage structure includes a base layer 1 and a precast slab 8. A drainage layer 2 is installed on top of the base layer 1, a surface layer 3 is installed on top of the drainage layer 2, geotextile 5 is laid on top of the base layer 1, and a permeable pipe 7 is installed on top of the drainage layer 2.

[0027] See Figure 1 The base layer 1 can be replaced by a precast slab 8, which is connected by a rubber sealing strip 9, thereby improving the construction speed and joint waterproofing performance and ensuring compatibility.

[0028] See Figure 1 and Figure 2 The top of the surface layer 3 is provided with a ramp 4, which slopes outwards from the building, allowing water to be quickly discharged to the outside of the building.

[0029] See Figure 3 The geotextile 5 is placed between the base layer 1 and the drainage layer 2. Four pins 6 are symmetrically inserted into the inner wall of the geotextile 5, and the pins 6 extend to the inner wall of the base layer 1. This allows the geotextile 5 to prevent soil particles from clogging the drainage layer 2, and the pins 6 can be used to position the geotextile 5, ensuring the stability of the geotextile 5 and preventing it from easily detaching from the top of the base layer 1.

[0030] See Figure 2 There are multiple permeable pipes 7, and the multiple permeable pipes 7 are evenly distributed in the middle of the drainage layer 2 and the surface layer 3, so that the permeable pipes 7 can guide water into the drainage layer 2. The use of multiple drainage layers 2 can ensure the thoroughness of water guidance.

[0031] See Figure 2 The permeable pipe 7 is a 100mm diameter PVC porous pipe, which ensures its durability and prevents it from being easily damaged after long-term use.

[0032] See Figure 1 - Figure 3 Geotextile 5 is made of polypropylene, drainage layer 2 is graded crushed stone with a particle size of 5-20mm, and base layer 1 is a compacted soil base. This allows geotextile 5 to act as an impermeable layer, isolating seepage water from different soil layers, protecting the stability of the roadbed structure, and reducing the erosion of materials by water.

[0033] Working principle: When using this device, rainwater flows through the slope 4 of the concrete surface layer 3 to the permeable pipe 7. The permeable pipe 7 guides the water into the drainage layer 2. The drainage layer 2 quickly drains the water to the outside of the building through graded crushed stone. The geotextile 5 is used to prevent soil particles from clogging the drainage layer 2.
