Abstract
The utility model discloses a ground water-filtering ditch used in a building project. The ground water-filtering ditch comprises a drainage ditch (1) arranged around a drying bed, wherein a filtering device is arranged in the drainage ditch (1); the lowest layer of the filtering device is a reinforced concrete drain board (2); and a coke slag layer (3), a big pebble layer (4), a small pebble layer (5) and a polyester needle punched geotextile (6) are sequentially arranged on the reinforced concrete drain board (2) from bottom to top. After being filtering through the polyester needle punched geotextile (6), the small pebble layer (5), the big pebble layer (4) and the coke slag layer (3), water flows to the bottom of the drainage ditch (1) through holes on the reinforced concrete drain board (2) and is drained from the drainage ditch (1). The ground water-filtering ditch has the advantages that: the filtration effect is good; and the ground water-filtering ditch is not easy to block, reliably drains and can be used for a long time.
Description
Technical field
The utility model relates to a kind of drainage ditch, particularly relates to the ground drainage ditch of using in a kind of construction work, belongs to the water discharge technology field of construction work.
Background technology
Often there is water-containing materials (as moisture flyash, mud) to need to handle after the nature mummification in the industrial construction, constantly has liquid water to secrete in the natural drying process, simultaneously with fine granular materials.Usually establishing the open drain on the drying bed next door collects moisture and enters pipeline.But because the gutter does not have effective filtration system, the blocked situation of gutter or pipeline often takes place, influence is produced normally.
The utility model content
The purpose of this utility model is, the ground of using in a kind of construction work drainage ditch is provided.Good filtration effect is not easy blockedly, and draining is reliable, can use for a long time.
The technical solution of the utility model: the ground drainage ditch of using in a kind of construction work, comprise and be located at drying bed gutter on every side, be provided with filter in the gutter, the lowermost layer of filter is the steel bar concrete band drain, top cinder layer, rubble layer, thin boulder bed and the polyester acupuncture geotextiles of being provided with successively from the bottom to top of steel bar concrete band drain.
In the ground drainage ditch of using in the aforementioned construction work, described steel bar concrete band drain is provided with the hole.
In the ground drainage ditch of using in the aforementioned construction work, described cinder layer thickness is 100～140mm.
In the ground drainage ditch of using in the aforementioned construction work, described cinder layer thickness is 120mm.
In the ground drainage ditch of using in the aforementioned construction work, described rubble layer thickness is 40～60mm.
In the ground drainage ditch of using in the aforementioned construction work, described rubble layer thickness is 50mm.
In the ground drainage ditch of using in the aforementioned construction work, the cobble particle diameter of described rubble layer is 12～20mm.
In the ground drainage ditch of using in the aforementioned construction work, described thin boulder bed thickness is 20～40mm.
In the ground drainage ditch of using in the aforementioned construction work, described thin boulder bed thickness is 30mm.
In the ground drainage ditch of using in the aforementioned construction work, the cobble particle diameter of described thin boulder bed is 5～10mm.
Compared with prior art, the utility model is gone into 1 bottom, gutter by the orifice flow on the steel bar concrete band drain 2 after polyester acupuncture geotextiles 6, thin boulder bed 5, rubble layer 4 and cinder layer 3 filter, discharge from gutter 1.Good filtration effect is not easy blockedly, and draining is reliable, can use for a long time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-gutter, 2-steel bar concrete band drain, 3-cinder layer, 4-rubble layer, the thin boulder bed of 5-, 6-polyester acupuncture geotextiles.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.
The utility model as shown in Figure 1.The ground drainage ditch of using in a kind of construction work, comprise and be located at drying bed gutter 1 on every side, be provided with filter in the gutter 1, the lowermost layer of filter is a steel bar concrete band drain 2, top cinder layer 3, rubble layer 4, thin boulder bed 5 and the polyester acupuncture geotextiles 6 of being provided with successively from the bottom to top of steel bar concrete band drain 2.Described steel bar concrete band drain 2 is provided with the hole.Described cinder layer 3 thickness are 100～140mm, and optimum thickness is 120mm.Described rubble layer 4 thickness are 40～60mm, and optimum thickness is 50mm.The cobble particle diameter of described rubble layer 4 is 12～20mm.Described thin boulder bed 5 thickness are 20～40mm, and optimum thickness is 30mm.The cobble particle diameter of described thin boulder bed 5 is 5～10mm.
During concrete enforcement, can be in the gutter 1 bottom construct some supports, then steel bar concrete band drain 2 is supported on, make between the bottom of trench in steel bar concrete band drain 2 and gutter 1 and formed the hydrospace.Steel bar concrete band drain 2 is provided with the hole, makes water can flow into the hydrospace from the hole.It is thick earlier to lay 120mm with cinder on steel bar concrete band drain 2, forms cinder layer 3, is that the cobble shop 50mm of 12～20mm is thick with particle diameter on cinder layer 3, formation rubble layer 4.On rubble layer 4, be that the cobble shop 30mm of 5～10mm is thick, form thin boulder bed 5 with particle diameter.Lay one deck polyester acupuncture geotextiles 6 from the bottom to top successively at thin boulder bed 5 upper berth one decks at last.Have fine grain water after polyester acupuncture geotextiles 6, thin boulder bed 5, rubble layer 4 and cinder layer 3 filter from what natural drying bed was discharged, go into 1 bottom, gutter, from gutter 1, discharge by the orifice flow on the steel bar concrete band drain 2.
