Description

Technical Field

[0001] The invention belongs to the technical field of road engineering, and in particular relates to a breathing intelligent water reduction system suitable for roadbed engineering structures. Background Art

[0002] During the roadbed construction process, soil moisture is an important factor affecting the stability and bearing capacity of the roadbed. Heavy rains and rainstorms are frequent in the summer along the project line in the temperate monsoon climate, causing the water content of the roadbed filler to be far higher than the optimal water content and in an over-wet state. The quality of roadbed compaction is difficult to control, and the construction is forced to stop for paving and drying, which prolongs the project cycle. The application of traditional water-reducing materials in roadbeds is limited, and it is impossible to actively adjust the soil moisture according to the temperature in different seasons, resulting in a series of problems such as the roadbed filler being too wet and difficult to compact during the rainy season, frost heave problems in winter, or deformation and damage under dry conditions.

[0003] Existing technologies aim to solve the problem of excessive moisture content in roadbed fillers during rainy season construction. Current commercial applications usually include using air pumps to apply subatmospheric pressure in the gravel layer, removing excess free water through vacuum or adding quicklime to mix and manually turning the gravel. However, this method is time-consuming and labor-intensive, not only occupying site space, but also prolonging the construction period. Summary of the invention

[0004] In order to solve the problems existing in the background technology, the present invention provides a breathing intelligent water reduction system suitable for roadbed engineering structures. A system is made of existing water-reducing materials. The system is suitable for roadbed projects with heavy rainfall and prone to frost heave in winter. By reasonably regulating the storage and drainage facilities in different areas, the water reduction effects of high-temperature water absorption, low-temperature drainage, and directional water conduction are achieved. The system includes a water storage and drainage blanket with water storage columns. The fine-grained filler in the gaps can meet the compaction performance during use; a drainage device connected to a power source is also provided under the water storage and drainage blanket to achieve directional drainage. The system can more efficiently remove excess free water in the roadbed and reduce labor consumption or mechanical intervention. As long as there is excess free water in the filler profile, the system will continue to function.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0027] Furthermore, the water storage column fixing frame 2 is provided with a plurality of slots 22 arranged in an array, and the plurality of water storage columns 3 are correspondingly arranged in the slots 22. The plurality of slots 22 arranged in an array do not interfere with each other, and can be arranged symmetrically or staggered.

[0028] Preferably, the water storage column fixing frame 2 is located in the middle layer of the water storage and drainage blanket, and the coil or sheet made of water-reducing material is located above and below the water storage column fixing frame 2.

[0029] Furthermore, the water-reducing material includes a combination of one or more of non-woven fabrics, industrial waste blankets, rock wool, waste cloth, cotton thread, straw, plastic net, sponge, glass wool, polyester fiber, glass fiber, organic fiber and other soft porous materials. Preferably, the non-woven fabric is made of a combination of one or more of polypropylene, acrylic and polyester.

[0030] Furthermore, a plurality of protruding structures 21 are arranged around the water storage column fixing frame 2 , and a limiting slot 11 is arranged around the inner periphery of the outer frame 1 , and the plurality of protruding structures 21 are arranged inside the corresponding limiting slot 11 .

[0031] Furthermore, the peripheral frame 1 is provided with a plurality of penetration holes 12 , and the penetration holes 12 are communicated with the limiting slots 11 .

[0032] Furthermore, a plurality of water-permeable holes 13 are evenly distributed on the side wall of the outer frame 1 , and the water in the water-reducing material can flow out through the water-permeable holes 13 .

[0033] Furthermore, the drainage blanket has a thickness of 30-90 mm, a width of 5-1000 cm, and a length that can be customized or cut as needed.

[0034] Further, the drainage device comprises a water pump and a conduit, the conduit is mounted on the water pump, and each of the drainage pipes 5 is connected to the conduit. The water flow inside the water storage column 3 is discharged into the water tank through the water pump.

[0035] Furthermore, the barrier layer 4 is a sheet or coil with a thickness of 3-5 mm made by calendering or extruding a water-reducing material. The barrier layer 4 is loose and porous, and rainwater can pass through the barrier layer 4 into the water storage column 3, while foreign matter mixed in the rainwater will be intercepted by the barrier layer 4 to prevent it from entering the water storage column 3 under the action of gravity and causing blockage.

[0036] The drainage blanket of the present invention can meet the construction compaction characteristics, avoid collapse, and can carry out normal drainage.

[0037] Refer to the instruction manual Figure 1-5 When the present invention is actually used, firstly, several water storage columns 3 are fixedly connected in the card slots 22 of the water storage column fixing frame 2, and then the barrier layer 4 is covered on the top of several water storage columns 3, and the raised structures 21 around the water storage column fixing frame 2 are connected with the limit card slots 11 around the outer frame 1 to achieve fixation. When the water storage and drainage blanket contacts the roadbed filler with high water content, the barrier layer 4 processed by spraying is loose and porous, and the excess free water can pass through the barrier layer 4 and be absorbed by the water-reducing material therein, while the fine aggregate components in the roadbed filler will be intercepted by the barrier layer 4. When it rains, the free water flows into the water storage column 3 by the action of gravity for storage, and finally the stored water can be guided to be discharged in a directional manner by connecting the drainage device of the power device. During the roadbed construction, the strength of the configured material can meet the construction compaction requirements and play a good supporting role, which can avoid the collapse of the water storage and drainage blanket and is conducive to the normal water storage and drainage of the water storage and drainage blanket.

The cylinder is 3-5mm thick and can pass fluids. The material has the functions of moisture-proof and root-proof.

[0039] The actual method of use on site is: after removing sharp objects from the roadbed filler, lay a drainage blanket on the base layer to compact the roadbed filler. The drainage blanket can be fixed to the base layer by empty laying, weighting, gluing, or nailing; around the periphery of the drainage blanket and at the nodes therein, use water-permeable, moisture-proof, and root-proof homogeneous rolls to glue, hot-melt, or hot-air seamlessly overlap the rolls; then connect the drainage device to the power device to achieve a directional water guide and drainage effect.
