Description
Technical Field
The utility model relates to the technical field of soft soil and sandy soil roadbed reinforcing parts rich in surface water in civil engineering, in particular to a one-way water permeable hexagonal filling frame.
Background
In civil engineering construction, poor soil quality conditions are often encountered, particularly soft fine sandy soil, fine silt and the like in the north and the northwest of China. The soil is hard when dry, and once rainwater comes or winter snow melts every year, the soil becomes soft when meeting water and runs off quickly, so that common reinforcement is difficult to perform, and the embankment is extremely easy to collapse. The common means is to adopt the method of changing soil and filling, but the cost of changing soil and filling is very high, and the transportation workload is very large. The new method is to adopt the geocell for reinforcement, the geocell is used as a reinforced reinforcement material with a certain height, so that the platform effect of the deep foundation is formed, the bearing capacity of the soil can be greatly improved, the local soil is directly used as a filler, the replacement and filling are not needed, and the method is used for reinforcing the soft foundation, the roadbed, the side slope protection, the reinforced retaining wall, the dam and the like, and achieves better effect.
Prior art geocells are diamond-shaped honeycomb structures of polyethylene or polypropylene plastic sheet material arranged and joined together at nodes. The geocell adopting the polyethylene extruded sheet is characterized in that two adjacent sheets are welded at a certain distance by an ultrasonic welding technology, and a plurality of welded and connected whole sheets are stretched and unfolded to form a rhombic honeycomb shape. The tensile strength of the geocell adopting the polyethylene extruded sheet is not high, the tearing strength of the ultrasonic welding node is low, the sheet is impermeable, the opening rate of the drilled drain hole on the sheet cannot be too high, and the possibility of water accumulation exists.
The geocell adopting the polypropylene extruded sheet is formed into a sheet by reheating and stretching, and a honeycomb structure is formed by inserting, riveting, heat sealing and other modes for longitudinal joint cutting by U-shaped steel nails. The geocell adopting the polypropylene extruded sheet has poor tensile strength and tear resistance of nodes of the sheet, and has the defect of complete water impermeability which cannot be overcome. Because the polypropylene sheet material is easy to tear along the stretching direction and cannot be perforated, the drainage cannot be realized, the defect that a plurality of projects need to strictly control the filling materials, only expensive filling materials such as granular cobblestones and the like can be filled, and the use of the filling materials is not practical at all in many places.
The geocell in the prior art has obvious defects, the quality and the service life of roadbed engineering can be seriously influenced, the tear resistance of nodes is not high, the nodes are frequently torn and damaged during mechanical filling and mechanical rolling construction, particularly, the water permeability is poor, the sheets also form a 'dense and waterproof' wall surface in a soil body, water cannot be drained transversely at all, rainwater or accumulated snow on the surface enters the soil body, micro runoff can be formed on the wall surfaces, and the micro runoff can flush away fine particles in the soil body, so that the compactness of the soil body is greatly reduced, the engineering collapses, sinks and the like to a certain degree, and even the whole engineering fails.
Therefore, a technique capable of overcoming the above-mentioned drawbacks has yet to be proposed.
