And the cable working well facilitates the first-acid repair of cable faults, reduces costs of the first-acid repair, and has the practicality for the laying of cables.
Description
Technical field
The utility model relates to a kind of active well of underground construction technical field, specifically is a kind of tee joint type cable working well.
Background technology
Existing underground utilities active well has several like this forms: active well and splicing prefabricated components formula active well that active well, cast-in-situ concrete active well, concrete block formula active well, splicing prefabricated components and the reinforced concrete cast-in-situ mode that adopts loam brick to be built into combines.Wherein, the active well of preceding four kinds of forms or have that intensity is low, easy to leak, non-resistant defective, or the deficiency of long, workmanship poor reliability of construction period is arranged.
Find by prior art documents, publication number is that (open day: Chinese utility model patent " precast splice type cable active well and job practices thereof " on December 20th, 2006) is disclosed to be a kind of straight cable work well to CN1880591A, only comprises two ports.Because of structure is too simple, the layout of underground utilities is restricted, can not satisfy the needs of various construction occasions.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of tee joint type cable working well is provided, and the utlity model has three ports and has enlarged working space, again can the different arrangement modes of appropriate cable.Be convenient to the cable fault repairing, reduce emergency repair cost, meet the practicality of cable laying.
The utility model is achieved through the following technical solutions, the utility model tee joint type cable working well comprises: prefabricated component blocks, seal and connector, described prefabricated component blocks comprises termination upper member piece, termination lower member piece, changeover portion upper member piece, changeover portion lower member piece, uphole end upper member piece, uphole end lower member piece, ponding well building block, and each upper and lower building block stack back of matching mutually highly is a well height degree; Be assembled into straight-through well body by prefabricated component blocks, respectively there is port at its two ends, also are provided with third connectivity mouth at the either side of well body; The seam crossing that all prefabricated component blocks are spliced mutually all is lined with seal, is connected by connector between the prefabricated component blocks.
Described third connectivity mouth is to be formed by stacking by third connectivity mouth upper member piece and the assembly unit of third connectivity mouth lower member piece; Third connectivity mouth upper member piece outstanding bucking ladder is arranged by the well side, with three changeover portion upper member pieces that third connectivity mouth splices mutually bucking ladder is arranged respectively also, the bucking ladder by complementation between third connectivity mouth upper member piece and the three changeover portion upper member pieces matches.
The corner that forms between third connectivity mouth and the well body, preferred arc.
The vertical height of the prefabricated component blocks that well body horizontal direction is adjacent is different, and the horizontal direction seam of promptly adjacent upper and lower building block is not in same horizon.
Compared with prior art, the utlity model has three ports and enlarged working space, again can the different arrangement modes of appropriate cable.Third connectivity mouth matches with three changeover portion upper member pieces of well dignity by being provided with the bucking ladder structure, can remove on the well body upper surface adding crossbeam from.Corner between third connectivity mouth and the well body is curved, on the corner weares and teares to prevent cable.The vertical height of the prefabricated component blocks that well body horizontal direction is adjacent is different, and the horizontal direction seam of promptly adjacent upper and lower building block is not in same horizon, to strengthen the assembly unit intensity of well body.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the structural representation of third connectivity mouth upper member piece;
Fig. 3 is the structural representation of three changeover portion upper member pieces;
The cross section structure schematic diagram of Fig. 4 for matching between third connectivity mouth upper member piece and the changeover portion upper member piece.
Mark is as follows:
