Abstract
The utility model relates to a composite reinforced, drained mattress for reinforcement, drainage of soft clay foundations in highways, municipal, industrial and civil buildings, which is characterized in that plastics are to be hot-melted and extruded into plastic filaments via a die; the plastic filaments are twined and coagulated with each other. Clearances are reserved on the cross section of the mattress so that a well-shaped drainage mattress can be formed before buried into subgrades. By means of the substitution for traditional sand layers and reinforced geogrids, the utility model has an advantage of simple structure to facilitate product industrialization, low cost, low labor intensity and high efficiency, convenience in construction and installation, two functions of drainage andreinforcement of soft clay foundations.
Description
Technical field
The utility model relates to a kind of drainage, the composite reinforced draining mattress of reinforced soft soil grounds such as particularly a kind of highway, civic building, draining.
Background technology
Before the utility model is made, in work progresss such as high-grade highway, municipal engineering, industry and civil building engineering, must carry out consolidation process to soft foundation, strengthen the stability of ground and reduce sedimentation.And discharging consolidation is the most general method of application that soft foundation is reinforced.This method is exactly to set plastic draining board or sand wick earlier in soft foundation, lays the thick sand sarking in 50 centimetres of left and right sides then on the ground as the horizontal drainage passage, toward contact 1-2 layer geo-grid will be set in sand cushion.The defective of this method is to need a large amount of sand material, and one comes the cost of transportation height, and two is coastal, riverine for the protection environment, adopts sand to be strictly controlled; In addition, use fiber reinforced grating for earth engineering that project cost is increased, make project total cost greatly increase.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, designs a kind of composite reinforced draining mattress and replaces sand cushion and fiber reinforced grating for earth engineering.
The technical solution of the utility model: its major technique is characterised in that and forms the well shape with extruding the plastics stick that the mutual winding of solidifying, plastic filament that the space is left in the centre make by mould behind the high temperature thermosol.
Its further technical characterictic is that the draining mattress is provided with link slot.
Advantage of the present utility model and effect are to substitute simultaneously sand sarking and fiber reinforced grating for earth engineering, save a large amount of expenses, and be simple in structure, be beneficial to suitability for industrialized production, cost is low, construction install convenience, the efficient height, labour intensity is low, can either draining can play reinforcement effect to soft foundation again.
Description of drawings
Fig. 1-the utility model structure chart.
I-I sectional drawing among Fig. 2-Fig. 1.
The application example figure of Fig. 3-the utility model in roadbed.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3: with plastics, adopt pp material in this example, at high temperature passing through mould extrusion plastic filament 1 behind the thermosol, is about 1 mm dia in this example, and plastic filament 1 twines mutually, become twisted shape, also resemble the instant noodles shape, belong to random winding, solidify then, some holes 2 are left in the centre, are made into well shape draining mattress 3; On the well shape draining mattress 3 link slot 5 is set, links to each other with band drain or sand wick in the ground 6; Use nonwoven 4 that well shape draining mattress 3 surfaces are all wrapped up.
During use: as shown in Figure 3, well shape draining mattress 3 is placed in the roadbed 6, the cavity of well shape draining mattress 3 is filled out soil, and it is upper and lower all to be soil, plays reinforcing road bed 6; The water of roadbed 6 bottoms is infiltration upwards, and to well shape draining mattress 3 places, water then trickles to its both sides horizontal direction along the hole 2 in the cross section of well shape draining mattress 3, discharges to roadbed 6 both sides; Nonwoven 4 Jiang Shui, soil separately avoid soil to enter the passage that stops up draining in the hole 2 in the well shape draining mattress 3, influence drainage effect; Well shape draining mattress 3 plays restrained deformation simultaneously, increases the reinforced action of stability.
Claims (5)
1. composite reinforced draining mattress is characterized in that forming the well shape with extruding the plastics stick that the mutual winding of solidifying, plastic filament that hole is left in the centre make by mould behind the high temperature thermosol.
