Description

For the gutter of deep overburden
Technical field
The utility model is related to a kind of gutter, more particularly, to a kind of gutter for deep overburden, belongs to Hydraulic structure builds affiliated facility design-build technical field.
Background technology
For the building in Hydraulic and Hydro-Power Engineering, such as the alluvial deposit foundation of house, dam, construction time draining is Very important project.If rainwater and construction waste water can not be discharged in time, it will cause foundation soil body to be immersed in water for a long time In, the physico-mechanical properties of the soil body, such as bearing capacity, shearing strength index will be significantly reduced because of softening, and then directly shadow Ring the mechanical characteristic and structure safety of building.
In order to discharge the rainwater in ground and construction waste water in time, conventional measure at present includes that coating excavates draining Ditch, and two kinds of cast-in-place concrete gutter, as shown in Figure 1, Figure 2 and shown in Fig. 3.Gutter is excavated for coating, its knot Structure feature is:Gutter is formed by excavating, trapezoidal section, gutter surface, including side slope and base plate are the exposed soil body, without mixed Solidifying soil mask.The major advantage of the structure is:Excavate and directly form gutter, construction is more facilitated.The main of the structure lacks Put and be:Concrete facing is not made in 1 gutter surface, and rainwater and construction waste water may be still infiltered into foundation soil body down, and then Influence the physico-mechanical properties of foundation soil body;2 when gutter side slope excavation slope is steeper, in the influence of rainwater and construction waste water Under, the side slope soil body may occur slump, and then block gutter, influence the normal operation of foundation drainage ditch.And it is mixed for scene Solidifying soil pours gutter, and its design feature is:By excavating what is formed in advance, trapezoidal or rectangular cross section basis is tied in gutter Structure, is then respectively provided with concrete facing on the gutter surface of the foundation structure, including side slope and base plate again, and concrete facing is Cast in situs is formed.The major advantage of the structure is:There is concrete facing on gutter surface, can effectively prevent rainwater and apply Oozed under work waste water, it is to avoid the physico-mechanical properties of influence foundation soil body, gutter operational effect is preferable.The major defect of the structure It is:1 gutter needs to carry out tunneling boring construction of concrete lining, complex, Site Template large usage quantity of constructing, to construction The requirement in place is also higher;2 for provisional construction time drainage system, after foundation engineering terminates, gutter concrete To go out of use, cause certain waste.
Utility model content
Technical problem to be solved in the utility model is:There is provided a kind of speed of application fast, construction cost is low, can be repeatedly many The gutter of the secondary alluvial deposit foundation for using.
For the technical scheme that solution above-mentioned technical problem is used is:A kind of gutter for deep overburden, bag Permeation-resisting structure layer is included, described gutter also includes backfill body and cast-in-place connector, after described permeation-resisting structure layer is prefabricated Dress antiseepage precast construction layer, between the rear dress antiseepage precast construction layer described in the adjacent two pieces excavated on the ground of gutter It is tightly connected by described cast-in-place connector;Along gutter flow to positioned at filling out for the rear dress antiseepage precast construction layer both sides Space is filled to be backfilled by described backfill body.
It is further that described rear dress antiseepage precast construction layer includes L-type prefabricated component, in the water of the L-type prefabricated component Cast-in-place reserving rib is provided with flat side;On the cross section in the gutter, the two of L-type prefabricated component described in two pieces positioned opposite Bar horizontal sides are tightly connected by described cast-in-place connector, and described cast-in-place reserving rib is located in described cast-in-place connector.
Such scheme it is preferable that, described L-type prefabricated component is plain concrete prefabricated component.
It is further that described rear dress antiseepage precast construction layer includes L-type prefabricated component and plate prefabricated component, described Bottom on the outside of the vertical edges of L-type prefabricated component is provided with cast-in-place reserving rib, is also provided with the side long of the plate prefabricated component There is the cast-in-place reserving rib for extending in the width direction;On the same cross section in the gutter, described plate prefabricated component sets Put between two vertical edges of L-type prefabricated component described in the back-to-back two pieces arranged, each vertical edges of the L-type prefabricated component Adjacent long edges with the plate prefabricated component are tightly connected by described cast-in-place connector, and described cast-in-place reserving rib is located at In described cast-in-place connector.
Such scheme it is preferable that, described L-type prefabricated component and described plate prefabricated component is plain concrete Prefabricated component.
It is further that described backfill body is cubic metre of earth and stone backfill body.
Such scheme it is preferable that, the cross section of excavation gutter ground is inverted ladder type structure.
The beneficial effects of the utility model are:The utility model by by existing permeation-resisting structure layer be improved to it is prefabricated after Dress antiseepage precast construction layer, and increase backfill body and cast-in-place connector, then utilize and excavate formation in advance on alluvial deposit foundation The excavation gutter ground in inverted trapezoidal section based on, rear dress antiseepage precast construction layer is assembled to described excavation draining On ditch ground, then by the cast-in-place connector described in the cast in situs based on the rear dress antiseepage precast construction of assembly layer, support After shield is qualified, then with after the completion of assembled, cast-in-place based on the outside in the gutter of dress antiseepage precast construction layer after described The described backfill body of backfill completes the construction in gutter described herein.Finally, built in hydraulic structure described herein Completion is made when no longer needing draining, removing backfill body that can soon also, antiseepage precast construction layer is filled after dismounting is lower need to next place Set on the alluvial deposit foundation in gutter that fast run-up goes out gutter as stated above again.Because gutter described herein is adopted It is main body that antiseepage precast construction layer is filled after being, in the excavation gutter ground in inverted trapezoidal section that excavation is formed in advance On, with cast-in-place connector as connector, to backfill body as the detachable gutter of reinforcing member, then, described rear dress antiseepage Precast construction layer can first carry out pouring shaping in advance, and only need assembly at the scene, and pour described in cast-in-place connector and backfill Backfill a small amount of work such as body, such that it is able to make speed of application become faster, and the cast-in-place connector of cast in situs and backfill institute During the backfill body stated, it is no longer necessary to template, and the rear dress antiseepage precast construction layer can be with recycling, so that construction Cost becomes lower, realizes once prefabricated nonexpondable purpose.
