Abstract
The utility model relates to a slightly arched reinforced concrete inspection well cover which is a stepped inspection well cover with a slightly arched surface and four flat and straight edges that are retracted inwards, wherein the inspection well cover is formed by cladding a slightly arched reinforcement cage taking the shape of a Chinese character 'mian' (which means 'surface' in English). The structure can greatly improve the rolling compaction resistance of the slightly arched reinforced concrete inspection well cover, and when the reinforced concrete inspection well cover is used for replacing a cast steel inspection well cover on the traditional inspection shaft, and the traditional inspection shaft curb does not need to be replaced.
Description
Technical field:
The present invention relates to a kind of inspection shaft lid, especially a kind of little arch formula steel concrete inspection shaft lid.
Background technology:
The inspection shaft continued to use at present lid owing to receive the step moulding restriction of inspection shaft mouth circle, can't make thicklyer thereby not withstand voltage, thereby can only adopt the bigger cast steel of tension force to make, but cast steel inspection shaft lid is prone to stolen.
Summary of the invention:
In order to guarantee the application safety of inspection shaft lid, the present invention provides a kind of little arch formula steel concrete inspection shaft lid, it is characterized in that four of inspection shaft lid is received steps in become and capping slightly upwards arches upward.The present invention implements with the following method: 1, with reinforcing bar weldering system inspection shaft lid skeleton; Skeleton is " face " font; " one " font on its top amplitude in length and breadth is slightly less than the last inboard breadth of inspection shaft mouth circle step; " returning " font of its underpart amplitude in length and breadth is slightly less than inspection shaft mouth circle step lower body inboard wide cut in length and breadth, and both are welded into " face " font and make " face " font from the central part 2cm that upwards arches upward; 2, coat skeleton with concrete and make little slightly arching upward but four inspection shaft lids on the face along receipts step in straight and the one-tenth.Benefit of the present invention is; The inspection shaft lid of having been thickeied has increased the anti-ability that rolls already; And its four edge has been become the immixture power that has the arch formula concurrently with the active force between inspection shaft mouth circle by the single formula of undertaking; Then further promote its anti-ability that rolls, and when existing inspection shaft being used instead inspection shaft lid of the present invention, must not replace existing inspection shaft mouth circle.
Description of drawings:
Fig. 1 is the specific reinforcing bar configuration diagram of the present invention; Fig. 2 is inspection shaft lid schematic appearance of the present invention; Fig. 3 is an application state deep cutting sketch map of the present invention.Among the figure, the 1st, inspection shaft mouth circle, the 2nd, inspection shaft lid of the present invention, the 3rd, the inspection shaft wall, the 4th, the outer ground of inspection shaft, the 5th, the inspection shaft lid is hung arm.
The specific embodiment:
Elder generation is as shown in Figure 2, reinforcing bar framework shown in Figure 1 is overmolding on the face with concrete arches upward slightly, but four edges is straight and become the interior step inspection shaft of receiving to cover.During application, inspection shaft lid (2) is fastened on the inspection shaft mouth circle (1) through hanging arm (5).
