Abstract

The utility model discloses a kind of drainage inspection well backfill structure, including inspection shaft inner core, protection well cap unit, inner cap, supercrust, native soil backfill layer, aggregate chips backfill layer, weak soil basal layer and concrete layer;Described protection well cap unit includes protection well cage and the protection well lid being positioned on described protection well cage;Described inner cap covers on described inspection shaft inner core;Described aggregate chips backfill layer is positioned on described weak soil basal layer;Described native soil backfill layer is positioned on described aggregate chips backfill layer;Described supercrust is positioned on described native soil backfill layer;Described concrete layer is wrapped in below described inspection shaft inner core.Beneficial effect: the earthwork around inspection shaft is almost without sinking, and structural strength is big, is repeatedly not easy after stress to destroy;Stablize the place of poor (i.e. WATER LEVEL CHANGES is bigger) at some water, inspection shaft inner core is not easy ponding.

Description

A kind of drainage inspection well backfill structure
Technical field
The utility model relates to construction engineering technical field, particularly relates to a kind of drainage inspection well backfill structure.
Background technology
Inspection shaft is used in the range of one residential (residential area, public building district, plant area etc.) that buried plastics pipe road external diameter is not more than 800mm, the depth of burying is not more than 6m, be generally located at drainage pipeline intersection, turning, caliber or gradient change, at drop etc., for the ease of make regular check on, clean and dredge or the plastics integrated injection molding of down-hole operation inspection form or brick become well shape structures.In prior art, inspection shaft is required for backfilling surrounding after construction.Existing backfill structure frequently can lead to the earthwork around inspection shaft and sinks more, and structural strength is little;Stablize the place of poor (i.e. WATER LEVEL CHANGES is bigger), the easy ponding of inspection shaft inner core at some water.
Utility model content
In view of the foregoing, the utility model provides that a kind of structural strength is big and inspection shaft inner core is not easy the drainage inspection well backfill structure of ponding.
For reaching above-mentioned purpose, the utility model solves its technical problem and be the technical scheme is that
A kind of drainage inspection well backfill structure, it is characterised in that: include inspection shaft inner core, protection well cap unit, inner cap, supercrust, native soil backfill layer, aggregate chips backfill layer, weak soil basal layer and concrete layer;Described protection well cap unit includes protection well cage and the protection well lid being positioned on described protection well cage;Described inner cap covers on described inspection shaft inner core;Described aggregate chips backfill layer is positioned on described weak soil basal layer;Described native soil backfill layer is positioned on described aggregate chips backfill layer;Described supercrust is positioned on described native soil backfill layer;Described concrete layer is wrapped in below described inspection shaft inner core.
Its further feature is as follows:
Described inspection shaft inner core is planomural inner core.
The concrete grade of described concrete layer is C30.
Due to the utilization of technique scheme, the utility model compared with prior art has a following beneficial effect:
The earthwork around inspection shaft is almost without sinking, and structural strength is big, is repeatedly not easy after stress to destroy;Stablize the place of poor (i.e. WATER LEVEL CHANGES is bigger) at some water, inspection shaft inner core is not easy ponding.
Brief description
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, the accompanying drawing of required use in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, content of the present utility model is described in further detail:
Refering to Fig. 1, a kind of drainage inspection well backfill structure, it is characterised in that: include inspection shaft inner core, protection well cap unit, inner cap the 3rd, supercrust the 4th, native soil backfill layer the 5th, aggregate chips backfill layer the 6th, weak soil basal layer 8 and concrete layer 9;Described protection well cap unit includes protection well cage 2 and the protection well lid 1 being positioned on described protection well cage;Described inner cap covers on described inspection shaft inner core;Described aggregate chips backfill layer is positioned on described weak soil basal layer;Described native soil backfill layer is positioned on described aggregate chips backfill layer;Described supercrust is positioned on described native soil backfill layer;Described concrete layer is wrapped in below described inspection shaft inner core.Described inspection shaft inner core is planomural inner core.The concrete grade of described concrete layer is C30.
Beneficial effect: the earthwork around inspection shaft is almost without sinking, and structural strength is big, is repeatedly not easy after stress to destroy;Stablize the place of poor (i.e. WATER LEVEL CHANGES is bigger) at some water, inspection shaft inner core is not easy ponding.
Above-described embodiment is only for illustrating that technology of the present utility model is conceived and feature; its object is to allow person skilled in the art will appreciate that content of the present utility model and to be carried out; protection domain of the present utility model can not be limited with this; all equivalences made according to the utility model Spirit Essence change or modify, and all should cover in protection domain of the present utility model.
