Abstract
The utility model relates to a steel fiber concrete flash edge well base for an inspection well. The steel fiber concrete flash edge well base is characterized in that the lower part of the outer side of a well base [2] is outward provided with at least the structure of a concrete flash edge step [8], and the concrete flash edge step [8] is formally staggered with a contact surface in a circumferential direction at the outer edge of the well base [2]. The principle of the utility model is as follows: the sloping edge or the straight edge of the outer edge of the original well base is improved into a flash edge structure with a concave-convex shape, the contact surface is improved in a staggering contact form, thereby, the combining of the outer edge of the well base and an asphalt road surface is more firm, more reliable, and the outer edge of the well base and the asphalt road surface are not easily separated, and the contact surface between the well base and an upper covering plate is increased. The well base is not easily shifted.
Description
Technical field
Structures such as the steel fibrous concrete manhole of underground pipelines such as the utility model relates to electric power in urban road, highway, biotope, industrial occupancy and the greenbelt, communicates by letter, broadcasting, TV, combustion gas, street lamp, water supply and rainwater, sink hole relate in particular to a kind of ground support structure of this manhole well lid (being commonly called as manhole cover).
Background technology
The underground underground utilities that are equipped with usually such as urban road, highway, biotope.For the ease of the examination and maintenance underground utilities, need on the ground of laying these underground utilities, manhole be set.Manhole is generally built one at a certain distance on the underground utilities position, mainly supply service conduits, and the pipeline of removing mud and being used to connect different directions, differing heights uses.Manhole is a ground vertical shaft, and the well head place is provided with well lid and bearing, and bearing is the supporting construction of well lid, is made up of well seat and last cladding plate two parts, and well seat and last cladding plate are fixed in well head place, ground, and well lid is installed on the well seat, sees shown in the accompanying drawing 1.Well seat outer side edges in above-mentioned original seat structure is a hypotenuse, and have following three shortcomings in actual use: 1, the pitch on road surface and the contact surface between the hypotenuse are little, and pitch is cannot kept under control the well seat; 2, contact surface is less between well seat and the last cladding plate, under external force displacement easily; 3, after road was delivered for use, well seat outside can be because of the long-term extruding of driving vehicle, produce ditch between flexible pavement and the well seat outside and stitch, rainy day ponding, when vehicle was passed by, sewage spattered the pedestrian with water.
Summary of the invention
The utility model purpose provides a kind of steel fibrous concrete manhole overlap well seat, and to be the pitch that makes the road surface improve with the fastness that contacts between the well seat its purpose one; The 2nd, solve the problem that the well seat is shifted under external force easily; The 3rd, further improve the compactedness of well seat.
For achieving the above object, the technical solution adopted in the utility model is: a kind of steel fibrous concrete manhole overlap well seat, its innovation is: well seat outer lower portion outwards is provided with at least one circle concrete overlap ledge structure, this overlap step in well seat outer circumference to the staggered contact surface of form.
Related content and change interpretation in the technique scheme are as follows:
1, in the such scheme, described " at least one circle concrete overlap ledge structure " comprises variations such as a circle, Liang Quan and three circles, wherein one encloses overlap step best results, and structure is the simplest.The overlap step circumferentially can be put in order circle along the well seat and be provided with continuously, also can be provided with at interval, as zigzag etc.
2, in the such scheme, the overlooking profile and can be shapes such as circular, square or rectangle of described well seat.
3, in the such scheme, in order to prevent to gnaw the limit phenomenon, stirrup (band iron outside being commonly called as) outside can being provided with in the well seat outer ring on overlap step top.Be somebody's turn to do the interior best results of concrete overlap step body of embedding bottom, outer stirrup lower end.
4, in the such scheme, can be provided with interior stirrup (being commonly called as interior band iron) in well seat inner circumferential, in this between stirrup and the outer stirrup interval adopt the reinforcing bar electric welding to be connected, and reinforcing bar is embedded in the concrete.Outer stirrup and interior stirrup material therefor can be ferrous metal, also can be non-ferrous metals, as band steel, stainless steel and high-strength aluminum alloy etc.
5, in the such scheme, can in the concrete of well seat bottom, be embedded with the cage of reinforcement structure, the appearance similar of the skeleton of this reinforcing bar and well seat bottom.
The utility model principle is: the hypotenuse or the straight flange of original well seat outside are improved to the overlap structure of being with concave-convex type, improve contact surface with staggered contact form, thereby make well seat outside more solid and reliable with combining of flexible pavement, not easily separated.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model well seat outer side edges bottom increases at least one circle concrete overlap, has so both made outer stirrup be difficult for sinking, and has increased the contact surface between well seat and the last cladding plate again, and the well seat is difficult for displacement; Make pitch be improved to staggered the contact with plane contact between the well seat simultaneously, contact surface is bigger like this, and the contact fastness is better.
2, stirrup structure in the utility model well seat inner side edge is continued to use, outer side edges has been set up outer stirrup structure, and so new well seat just uses on road can not gnawed the limit.
3, the electric welding of employing reinforcing bar is connected between the outer stirrup of the utility model well seat and the interior stirrup, reinforcing bar is circumferentially being arranged at interval, keeping firmly bonding strength between inside and outside like this stirrup and steel fibrous concrete, thereby inside and outside stirrup can to any direction, tiltedly not suppressed simultaneously inside and outside stirrup play in steel fibrous concrete again and sink.
4, the utility model stirrup outside the well seat embeds in the concrete, be provided with cage of reinforcement in the concrete of outer stirrup bottom, increased the concrete compactedness of overlap step part like this, therefore in the road construction process, even road roller is pressed onto well seat outside because of carelessness when the compacting asphalt pavement, can not damage yet.
