Description
Technical field
The utility model belongs to manhole construction field, and relating to a kind of is in particular that the one that circular manhole uses carries the building block of assembling chain-type manhole for masonry shaft, well room.
Background technology
Manhole be for the power supply, feedwater, draining, blowdown, communication, cable television, gas pipe, public lighting circuit etc. of Urban Underground infrastructure keep in repair, easy for installation and arrange.Generally being located on pipeline intersection, turning, caliber or gradient change place and straight line pipeline section and locating at a certain distance, is be convenient to make regular check on ancillary structure, usually needs unwrapping wire and the inspection of it being carried out to pipeline or circuit inside manhole.In prior art, the inner metope of manhole mostly is full closeding state, there is no connection jaws or pipe joint, operation inconvenience, do not arrange of manhole building block of the prior art simultaneously coordinates mounting limit block more, assemble in process at manhole metope and there will be deviation, cause manhole phenomenon off quality, even life can be caused to injure to operating personnel.In prior art, also the limited block and stopper slot that the manhole building block of a small amount of model are provided with and are convenient to connect is had, such as: the patent manhole building block (patent No.: 201120131766.5), disclose the building block that a kind of two ends are provided with dovetail groove, and utilize the clamping corresponding to swallow-tail form tongue-and-groove of independent swallow-tail form tenon, the spacing connected mode of this mode, complex operation, increase operating personnel and build the workload of building manhole, simultaneously single swallow-tail form tenon very easily in transport or use procedure by along bad, cause the waste of material or cause the avalanche of manhole.
Utility model content
The purpose of this utility model is that providing a kind of is provided with pipeline interface and carries the trivial manhole building block of assembling chain.
The building block of technical solutions of the utility model one assembling chain trivial formula manhole, comprise the block body of arc, described block body one end is provided with the connection projection stretching out block body, described connection projection is dove-tail form, the described block body other end is provided with the connecting groove of recessed block body, described connecting groove is dovetail groove, block body upper surface is provided with stopper slot near arc outer side edges edge, block body soffit is provided with the spacing card article adapted with stopper slot, described block body upper surface is provided through the longitudinal hole of upper surface and soffit, block body medial surface is provided with the cross through hole be communicated with longitudinal hole.
Preferably, in described block body, longitudinal hole has been arranged side by side two, and described cross through hole has been arranged side by side two.
Preferably, connection projection and connecting groove shape adapt, and described connection size of lug is less than connecting groove size.
The one assembling chain trivial formula manhole building block of technical solutions of the utility model, this building block is the concrete block with certain radian that applicable manhole uses, dove-tail form is set respectively at building block two ends and connects projection and connecting groove, assemble in process at manhole, connect before and after two pieces of building blocks, connection projection by adjacent two pieces of building blocks is connected with connecting groove, reaches and connects and fixing effect, avoids the phenomenon occurring in the process assembled at manhole metope that metope projection or metope cave in.
The one assembling chain trivial formula manhole building block of technical solutions of the utility model, building block upper and lower surface is respectively arranged with stopper slot and spacing card article, two neighbouring building blocks are located in the process assembled convenient, in the process that manhole assembles, can not ensure to assemble the building block that a circle uses is just in time integer, often need to carry out length cut to the building block of a piece or two pieces, so in some cases, the connection projection being arranged on building block both ends just can not play the spacing effect with being connected with connecting groove, and be arranged on the stopper slot of building block upper and lower side and spacing card article can realize building block location from vertical direction, building block is avoided to occur the phenomenon of skew.
The one assembling chain trivial formula manhole building block of technical solutions of the utility model, building block arranges the longitudinal hole through upper and lower surface, and the cross through hole being communicated with longitudinal hole is set on the medial surface of building block, make pipeline can be undertaken connecting up and unwrapping wire by longitudinal hole and cross through hole, avoid punch operation, save time, avoid the destruction to manhole metope, extend the application life of manhole, improve the safety factor of manhole.
The one assembling chain trivial formula manhole building block of technical solutions of the utility model, connection projection and connecting groove shape adapt, described connection size of lug is less than connecting groove size, the operator being is when assembling manhole, appropriate bonded adhesives can be added in connecting groove, when being placed in connecting groove by connection projection, under the effect of bonded adhesives, the building block adjacent being between two connects more firm.
The utility model technology beneficial effect:
The one assembling chain trivial formula manhole building block of technical solutions of the utility model, structure is simple, location is installed convenient, pipeline routes unwrapping wire is convenient, block body is lighter, reduce the pressure of manhole top building block to lower blocks, improve quality and the safety factor of manhole, extend the application life of manhole; The block body that this practicality is emerging is provided with and connects projection and connecting groove by the dove-tail form of auto-lock function, after dove-tail form in adjacent two building blocks connection projection is connected with connecting groove, just there is an auto-lock function, building block there will not be cheaply in a lateral direction, improves the fastness of the metope of manhole.
