Abstract
A connection structure of the upper portion and the middle of a glass fiber reinforced plastics inspection well solves the problem that installation of the inspection well is low in speed and efficiency. The technical scheme includes that the connection structure of the upper portion and the middle of the glass fiber reinforced plastics inspection well is used on the bottom end of the upper portion and the top end of the middle of the glass fiber reinforced plastics inspection well, the bottom end of the upper portion of the glass fiber reinforced plastics inspection well is connected with the top end of the middle of the glass fiber reinforced plastics inspection well, and the key is that the connection structure comprises an inserting groove which is of diameter variation structure and formed in the top end of the middle of the glass fiber reinforced plastics inspection well, an adhesive layer is arranged in the inserting groove, and the bottom end of the upper portion of the glass fiber reinforced plastics inspection well, which is of tubular structure, is inserted into the top end of the middle of the glass fiber reinforced plastics inspection well in gluing mode. The connection structure of the upper portion and the middle of the glass fiber reinforced plastics inspection well has the advantages of being convenient to install, and saving installation time and improving installation efficiency due to the fact that the upper portion of the inspection well is directly inserted into the middle of the inspection well in gluing mode.
Description
Technical field
The utility model belongs to municipal engineering field, relates to a kind of syndeton of top and middle part of fiber glass reinforced plastics inspection well, particularly a kind of top of fiber glass reinforced plastics inspection well and syndeton at middle part that improves installation effectiveness.
Background technology
In the draining of municipal engineering, blowdown pipelines, manhole is a kind of important equipment, in checking pipeline, dredging pipeline, there is important effect, but, existing manhole adopts stone or brick one-tenth more, and the manhole speed of application of stone or brick one-tenth is slow, need the time of two weeks to month, difficulty of construction is large.
Summary of the invention
The utility model object is to overcome the deficiencies in the prior art, has designed a kind of easy for installationly, saves the top of fiber glass reinforced plastics inspection well and the syndeton at middle part of set-up time, and the speed of application that has solved manhole is slow, inefficient problem.
The utility model is that the technical scheme that realizes goal of the invention employing is, a kind of top of fiber glass reinforced plastics inspection well and the syndeton at middle part, the bottom that comprises top, the top at middle part, the bottom on top is connected with the top at middle part, key is: described syndeton comprises the slot of top, the middle part setting with variable-diameter structure, the adhesive layer in slot, and the bottom grafting with the top of tubular structure is adhesive in the top at middle part.
Operating principle of the present utility model is that in the middle part of the bottom on the top of manhole is plugged into,, on the slot on top, the adhesive layer of slot is fixed together top and middle part firmly, connects very convenient.
The beneficial effects of the utility model are, quick and easy for installation, have reduced the set-up time, have greatly improved installation effectiveness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1 represents top, and 2 represent middle part, and 3 represent adhesive layer, and 4 represent slot.
The specific embodiment
A kind of top of fiber glass reinforced plastics inspection well and the syndeton at middle part, the bottom that comprises top 1, the top at middle part 2, the bottom on top 1 is connected with the top at middle part 2, key is: described syndeton comprises the slot 4 of the middle part 2 tops settings with variable-diameter structure, at the adhesive layer 3 of 4 li of slots, the bottom grafting with the top 1 of tubular structure is adhesive in the top at middle part 2.
The thickness of described adhesive layer 3 is 0.2-1cm.
Described top 1 is cylindric, and diameter is 700mm.
The variable-diameter structure that described middle part 2 is formed in one, maximum diameter is 1400-1600mm.The utility model is when concrete use, and manhole installation personnel, directly pegs graft the bottom on manhole top to be glued to the top at middle part, installs very convenient.
