Description
Technical field
The utility model relates to a kind of three-dimensional composite plastic water discharging body, belongs to building engineering field, be applicable in the construction work as vertical and level to water discharging body be applied to during drainage blanket and ground process.
Background technology
Water discharging body has than polymorphic type, such as discrete material pile, plastic draining board, 3 D stereo water discharging body, flexible porous tube etc., comparatively be widely used at present construction wall and basement bottom board percolating water compile with the engineerings such as eliminating, drainage blanket, soft basic consolidation in.
Vertical drainage body is for the efflux time that shortens the ground pore water, accelerates the consolidation process of soft base, normal employing vertically arranges the drainages such as sand wick, plastic draining board for Soft Ground, comparatively commonly used is plastic draining board at present, its principle is to utilize to be arranged in the plastic draining board of soft base as drainage channel, the load action that applies when top is when soft base, underground water rises in the bed course along band drain with capillarity owing to being squeezed, discharged to the outside by bed course, thereby the acceleration concretion of soft foundation is to improve bearing capacity of foundation soil and to reduce settlement after construction.Plastic draining board has replaced sand wick more and more owing to have that the cross-section of river is large, draining is unobstructed, quality is light, intensity is high and the characteristics such as easy construction, becomes a kind of comparatively desirable vertical drainage body.
The transverse row water body is the horizontal drainage body, usually uses sand cushion (medium coarse sand) or the plastic draining plate level is layed in the bed course, improves the bedding course drainage effect, and general more application is in the treatments of soft foundation such as highway engineering, building engineering.Comparatively Simple fast and cost are relatively low to lay sand cushion, but the drainability of sand cushion is very limited in actual the use, and easy silting, often are difficult to the drainage effect that reaches desirable.
Have at present the plastic draining plate level is layed in the bed course, accelerate the Engineering Projects of the application of bedding course drainage effect, but common plastics band drain resistance to tension is limited, produce excessive differential deformation on the basis, embankment and the medium easy fracture of dykes and dams roller compaction construction process or breakage, the draining central layer easily produces moderate finite deformation when overlying burden is larger, also be difficult to reach the drainage effect of anticipation, when the plastic draining plate level is layed in the bed course and uses as water discharging body, compare with using as vertical drainage body, it is stressed and be out of shape existence than big difference, in structure, the aspects such as material need to re-start design.
The 3 D stereo water discharging body is comprised of the plastic wire double-sided adhesive infiltration geotextiles of stereochemical structure, and alternative traditional sand grains and layer of gravel can promptly be discharged underground water.It can also play the effect of isolation and ground stabilization simultaneously, also is widely used in the engineering practice.Three general three-dimensional drains are because used material and self structure, in when, differential settlement occuring on the basis or being subject to larger extruding force its distortion larger, drainage performance can be had a strong impact on.
Flexible porous tube is a kind of composite geosynthetics that development in recent years is got up.It is comprised of with the tube wall lapping two large divisions with permeable filtration, protective effect the high strength steel wire ring as supporter, utilizes capillarity and siphon principle, makes gutter have suction and permeable effect, has comprehensive function withstand voltage, acid and alkali-resistance concurrently.But it has the single slope drainage function; And water-permeable pipe is deviate from from sand furrow sometimes in follow-up construction, and powerful negative pressure also can make flexible pipe incline and cause drainage channel blocked; The outer field coating of water-permeable pipe is easily aging under solar radiation in addition, must use as early as possible after devaning, so that the range of application of flexible porous tube has been subject to certain restriction.
In sum, need at present a kind of range of application that can effectively enlarge traditional band drain and flexible porous tube etc. of invention badly, drainage effect is good, have simultaneously good anti-extrusion performance, can be used as the vertical level that reaches and be applied to have the preferably three-dimensional composite plastic water discharging body of technical economic benefit in drainage blanket and the ground processing to water discharging body.
Summary of the invention
