Abstract
The invention provides a combined inspection shaft, characterized in that, block sheets with flanges at perimeter are combined to a hollow cylinder, through holes perpendicular to axial lines of the hollow cylinder are provided on the block sheets. So series of block sheets with flanges at perimeter of different arc lengths and different lengths can be produced according to the requirement, the inspection shaft with required diameter and length can be assembled conveniently according to the requirement, thereby sufficiently satisfying the requirements of different products for the user. Because the block sheets can be stacked, so the production and inventory spaces and the transportation space can not be occupied, the workshop and the store house investment and the transportation costs can be reduced, the sealing performance of the inspection shaft can be improved effectively, thereby ensuring the enough strength of the inspection shaft, the inspection shaft can be made of corrosion resistant waste plastics, the resource can be saved, the costs are low, and the invention is used for popularizing and applying widely.
Description
Technical field
The present invention relates to a kind of manhole, the combined inspection shaft that network of underground is imported and exported is manually overhauled, safeguards in especially a kind of conduct, belongs to network of underground ancillary facility technical field.
Background technology
In the urban construction process,, be the important component part of urban construction as the various network of underground of communal facility such as sewer, gas flue, cable communication pipeline etc.When laying various network of underground, except that the pipeline that uses big caliber, also need on pipeline, to be provided with at interval for manually overhauling, safeguard the import and export that various facilities are used in the pipe network---manhole.Existing manhole is used stone, brick one-tenth mostly, not only time-consuming, effort, and poor sealing performance, and infiltration causes to phreatic pollution with to environment damage easily.For this reason, people have released the monolithic manhole that glass fiber reinforced plastic or plastics are made, though solved problem such as leak, and installation is comparatively convenient, but bring difficulty for production, stock and transportation, not only take bigger production space and stock space, increase the investment of factory building and construction of warehouse, and take transport space, cost of transportation is increased, and transport capacity reduces, and the volume of this in addition monolithic manhole is comparatively single, can't adjust its volume size according to on-the-spot needs, be difficult to satisfy on-the-spot installation requirements.Therefore, be necessary fully prior art is improved.
Summary of the invention
The object of the present invention is to provide a kind of combined inspection shaft, fundamentally to solve production, stock and the transportation occupation of land that existing monolithic manhole brings, investment is big, the cost of transportation height, transport capacity is little, and volume is single, can't change problems such as volume size according to field requirement.
The present invention finishes by following technical proposal: a kind of combined inspection shaft is characterized in that it is combined into hollow cylinder by flanged (FLGD) sheet of periphery, and is provided with and the perpendicular through hole of hollow cylinder axis on the piece sheet therein.
Described sheet is made as cambered surface piece sheet, and perhaps flat blocks sheet is to constitute the hollow cylinder of circular cross-section or elliptic cross-section or square-section or triangular-section or polygonal cross-section or odd-shaped cross section.
Through hole on described sheet is established one at least, establishes conduit on the through hole, so that link to each other with network of underground, makes things convenient for the maintainer to enter work in the pipe network.
The flange face inboard of described sheet periphery is provided with groove, is provided with seal in the groove, so that when the piece sheet connects in twos, and the reinforcement sealing performance.
At interval connecting hole is set on the described periphery flange, connecting bolt is set in the hole, with convenient in twos between the piece sheet, combination between the hollow cylinder and dismounting in twos.
The external surface of described sheet is provided with crisscross reinforcing rib, with the intensity of reinforcing block sheet and hollow cylinder.
Described sheet is made as same radius or same widths or identical arc length respectively, the polylith of different length is so that be combined into same diameter according to actual needs earlier when installing, behind the multistage hollow cylinder of different length, be combined into the whole hollow cylinder of Len req, satisfy installation, instructions for use.
Described sheet is made as different arc or different radii or different in width respectively, the polylith of identical or different length, so that be combined into same diameter when installing according to actual needs earlier, behind the multistage hollow cylinder of identical or different length, be combined into the whole hollow cylinder of Len req, satisfy installation, instructions for use.
The present invention has following advantage and effect: adopt such scheme, can produce the flanged (FLGD) serial piece sheet of its periphery of different arc, radius, width and different length on request, after being transported to the use place, be assembled into hollow cylinder---the manhole of required diameter, length more on request easily.Because the piece sheet all can stack, neither take production, stock space after producing, do not take transport space yet, factory building, warehouse investment and cost of transportation have greatly been reduced, simultaneously during assembled on site, can be by actual needs, select the piece sheet of different length to be assembled into the manhole of required diameter and length, also can be assembled into the manhole of different cross section shape simultaneously as required, fully satisfy the demand of user different product.Flange connections of the present invention all is provided with highly reliable sealed groove in addition, seal is set in the groove, effectively improved the sealing performance of manhole, the reinforcing rib of piece sheet external surface ensures that effectively manhole has enough intensity in addition, and this manhole all can adopt corrosion resistant waste plastics to make in addition, therefore, economize on resources, and with low cost, application should be widely promoted.

The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described further the present invention, is not limited thereto but hold within the present invention.
Combined inspection shaft provided by the invention comprises the vertical hollow circular cylinder that the cambered surface piece sheet by band periphery flange 1,11 on its of six different lengths connects into, and all connections all connecting hole 14 on the flange 1,11 and the bolts in the hole 14 finish by being disposed on.Wherein, hollow circular cylinder is formed by connecting by three vertical hollow circuit cylinder sections, first section two isometric sheet 2 being grown by length combines, second section is also combined by two long isometric sheets 21 of length, be arranged with horizontal through hole on each piece sheet 21---inspection hole 4, so that be communicated with network of underground, the 3rd section two isometric sheets 22 of being lacked by length combine, as Fig. 1.
The external surface of each cambered surface piece sheet is equipped with crisscross reinforcing rib 3, as Fig. 1, wherein, the flange face of each cambered surface piece sheet periphery is that the inboard of 11 of the straight flanges of piece sheet both sides is provided with groove 12, establish weather strip 16 in the groove 12, the inboard that the circular arc flange at piece sheet two ends is 1 is provided with groove 13, establishes joint ring in the groove 13, as Fig. 3, Fig. 2.
