Description

Technical Field

[0001] This utility model relates to the field of three-dimensional composite drainage network technology, specifically to an anti-clogging three-dimensional composite drainage network. Background Technology

[0002] In civil engineering fields such as highway subgrades, railway subgrades, tunnel engineering, slope protection, and landfills, an effective drainage system is crucial to ensuring the long-term stability and safety of engineering structures. Traditionally, sand and gravel are used as drainage materials, but this approach suffers from problems such as heavy weight, low construction efficiency, high cost, and susceptibility to siltation and failure.

[0003] Therefore, three-dimensional composite drainage nets have emerged and are gradually becoming the mainstream drainage material. They provide drainage channels through a three-dimensional polymer mesh core and are combined with a geotextile filter layer to prevent soil particle intrusion, thus combining drainage and filtration functions. However, after long-term engineering practice, existing conventional three-dimensional drainage nets still have significant shortcomings:

[0004] 1. The core structure is mostly a simple mesh or rib structure, which has insufficient vertical compressive strength and overall rigidity. Under long-term overburden pressure or construction machinery load, it is prone to compression deformation or even crushing, resulting in a reduction or loss of valuable drainage space and a sharp drop in drainage efficiency.

[0005] 2. The installation and connection methods of existing products are usually relatively simple, such as relying on overlapping or special fasteners. However, these methods have problems such as weak connection strength, poor overall integrity, and complicated construction, making it difficult to quickly form a uniform and stable drainage layer, which affects construction efficiency and quality.

[0006] 3. Although it is composite with geotextile, the traditional planar bonding method may peel off under complex stress, and the core itself lacks effective support for the filter layer and secondary filtration structure, so there is still room for improvement in anti-clogging ability.

[0007] Therefore, in view of this, we studied and improved the existing structure and proposed a three-dimensional composite drainage network with anti-clogging properties. Utility Model Content

[0008] The technical problems to be solved by this utility model are: insufficient drainage and anti-clogging performance, inadequate structural stability and pressure bearing capacity, and weak installation connection strength between the three-dimensional composite drainage net body and the mounting frame.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a three-dimensional composite drainage net for preventing clogging, comprising a three-dimensional composite drainage net body and an installation frame, wherein the three-dimensional composite drainage net body comprises a three-dimensional mesh core, a support mesh is provided on the top of the three-dimensional mesh core, and a filter layer is provided on the top of the support mesh and the bottom of the three-dimensional mesh core; the three-dimensional mesh core consists of a mesh core plate, a reinforcing frame, a first support boss, and a second support boss.

[0010] The mounting frame holds the three-dimensional mesh core, the support mesh, and the two filter layers. The mounting frame includes two frame slots and two frame slots. Two C-shaped inserts are fixedly installed on one side of the frame slots. The two C-shaped inserts are respectively inserted into one end of the two frame slots. The connection between the frame slots is fixed by two bolts.

[0011] As a further embodiment of this utility model: the mesh core plate is provided with a plurality of filter holes, and the plurality of filter holes are distributed in a matrix on the mesh core plate; the reinforcing frame is provided with a plurality of frames, and each frame is fixedly installed in the corresponding filter hole.

[0012] As a further embodiment of this utility model: a plurality of support bosses are provided, and the plurality of support bosses are distributed in an array on the top of the core plate; a plurality of support bosses are provided, and the support bosses are fixedly installed on the top of the corresponding reinforcing frame.

[0013] As a further embodiment of this utility model: the support mesh is disposed on top of several support bosses one and several support bosses two.

[0014] As a further embodiment of this utility model: two bracket slots are arranged opposite to each other, two bracket slots are arranged opposite to each other, a bolt is movably inserted through the bracket slot, and one end of the bolt is threadedly connected to the corresponding C-shaped insert.

[0015] As a further embodiment of this utility model: the filter layer is a non-woven geotextile layer, and is fixedly composited on the top of the support net and the bottom of the three-dimensional mesh core by hot pressing.

[0016] Compared with the prior art, the advantages of this utility model are as follows:

[0017] 1. This utility model forms a stable three-dimensional drainage channel through a three-dimensional mesh core structure, multi-layer filter layers (support mesh and cloth filter layer) and matrix-distributed filter holes. It can effectively and quickly remove water while preventing soil particles from intruding and causing siltation, thus maintaining efficient drainage function for a long time.

[0018] 2. This utility model has internal reinforcement structures such as a reinforcing frame, a first support boss, and a second support boss, which enhance the overall rigidity and compressive strength of the mesh core, enabling it to withstand large external loads (such as soil pressure and engineering machinery pressure) and avoid structural deformation or collapse.

[0019] 3. The mounting bracket of this utility model adopts a plug-in and bolt fastening design, which realizes the rapid assembly and fixing of the three-dimensional drainage net body, improves construction efficiency, and facilitates transportation and on-site adjustment, adapting to the needs of different engineering scenarios.

[0027] 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.

[0028] As attached Figure 1-4 As shown, this utility model provides an anti-clogging three-dimensional composite drainage net, which is mainly composed of two parts: the three-dimensional composite drainage net body 1 and the mounting frame 2.

[0029] I. Structure and fabrication of the three-dimensional composite drainage net body 1:

[0030] The three-dimensional composite drainage net body 1 adopts a multi-layer composite structure. Its core is a three-dimensional mesh core, which is manufactured in one piece from polymer materials (such as HDPE and PP) through processes such as extrusion molding.

[0031] The mesh core plate 103 is the base of the entire structure and is flat. Several filter holes are evenly distributed on it in a matrix, which provide the main vertical channels for water flow.

[0032] The reinforcing frame 104 is a cross-shaped reinforcing rib structure installed in each filter hole (see appendix). Figure 4 Its edges are fused to or integrally formed with the inner wall of the filter holes, which greatly enhances the overall rigidity and compressive strength of the core plate 103 after the filter holes are opened, and prevents it from twisting and deforming under high pressure.

[0033] The support boss 105 is a frustum-shaped protrusion distributed in a matrix on the top surface of the mesh core plate 103, and is integrally formed with the mesh core plate 103.

[0034] Support boss 2 106 is a frustum-shaped protrusion fixedly installed on the top of each reinforcing frame 104, and its height is consistent with that of support boss 1 105.

[0035] A support net 101 is laid on top of the three-dimensional mesh core. The support net 101 is placed on top of all the support bosses 105 and 106. The support net 101 can be made of plastic flat mesh or metal mesh. Its main function is to provide uniform support for the upper filter layer 102 and prevent it from being locally pressed into the pores of the three-dimensional mesh core, thereby maintaining a drainage cavity at the top.

[0036] Finally, through a hot-pressing composite process, two layers of filter fabric 102 (preferably non-woven geotextile in this embodiment) are firmly bonded to the top surface of the support net 101 and the bottom surface of the three-dimensional mesh core, respectively. The top layer of filter fabric 102 is used to prevent upper fill soil particles from intruding and clogging the drainage cavities; the bottom layer of filter fabric 102 is used to prevent lower soil particles from intruding upwards into the mesh core. The hot-pressing method ensures the strong bond between the filter layers and the core structure, making them difficult to peel off.

[0037] II. Assembly and use of mounting bracket 2:

[0038] The mounting frame 2 is composed of two frame slots 1 201 and two frame slots 202. Its cross-section is usually "[" shaped, used to clamp and fix the four edges of the three-dimensional composite drainage net body 1.

[0039] Two rack slots 1 (201) are arranged opposite each other, and two rack slots 2 (202) are arranged opposite each other.

[0040] Two C-shaped inserts 203 are fixedly installed on one side of the second bracket slot 202 (they can be integrally injection molded with the second bracket slot 202 or fixed by welding). During installation, these two C-shaped inserts 203 are respectively inserted into the end slots of the two oppositely arranged first bracket slots 201 to achieve initial positioning and connection.

[0041] After initial insertion, bolt 204 is used for final tightening. Bolt 204 moves through the pre-set through hole on the second bracket 202, and its screw end is screwed into the pre-embedded threaded hole or nut on the corresponding C-shaped insert 203. Tightening bolt 204 will firmly lock the first bracket 201 and the second bracket 202 together, thereby firmly fixing the internal three-dimensional drainage net body to form a complete drainage net unit that is easy to transport and install.

[0042] After multiple drainage net units are transported to the construction site, they can be laid side by side and connected by connectors or overlapping methods to form a large-area, continuous, and highly integrated drainage layer.

[0043] The working principle of this utility model:

[0044] When water flows from top to bottom or bottom to top into the drainage net, it is first effectively filtered by the filter layer 102, blocking soil particles while allowing clean water to pass through. Water then enters the top drainage cavity formed by the support net 101, support protrusions 105 / 106, and the top filter layer 102, or enters the three-dimensional pores of the three-dimensional mesh core itself, where it can be quickly discharged horizontally. The internal reinforcement structure ensures that the drainage channels remain unobstructed even under high pressure.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
