The utility model discloses technical scheme's a hole building block of impervious type concrete inspection shaft multirow, the building block is when building the step inspection shaft, and it is many to connect the location position, convenient operation, reduction of erection time, the utility model discloses the building block of scheme can be followed a plurality of sides and a plurality of angle and prevented the moisture content infiltration, adopts this building block to build the inspection shaft of building, and the wall prevention of seepage is functional, and the whole security performance of inspection shaft is good, long service life.
Description
Technical field
The utility model belongs to manhole building block field, relates to a kind of concrete block of manhole impermeabilisation in particular.
Background technology
Manhole be mostly 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.Manhole is arrange and underground mostly, when raining or sprinkle water in road surface, namely rainwater on bottom surface can enter in manhole, or even the moisture content of manhole metope outside also can penetrate in manhole, moisture content under bottom surface passes through manhole side permeate for a long time in manhole, often cause subsiding of manhole or heaving of manhole sidewall, in the application life of serious curtailment manhole, even after maintainer enters shaft bottom, cause security threat.
Utility model content
The purpose of this utility model is to provide a kind of Anti-permeation concrete manhole many rounds building block with impermeabilisation ability, uniform force.
The building block of a kind of Anti-permeation concrete manhole of technical solutions of the utility model many rounds, comprise arc-shaped building block body, described this outside of arc-shaped building block is provided with vertical guiding gutter, arc-shaped building block body is provided through the through hole of upper surface and lower surface, the left side of arc-shaped building block body with right side be respectively arranged with connecting groove and be connected projection, in described arc-shaped building block body upper surface is close, outer arc side is all set to inclined plane, described arc-shaped building block body upper surface is formed in one, the convex surface that outer edge is downward-sloping, in described arc-shaped building block body lower surface is close, outer arc side is all set to inclined plane, described arc-shaped building block body lower surface is formed in one, the intilted concave surface of outer edge.
Preferably, described connecting groove is arranged at left side midline position, and runs through whole left side.
Preferably, described connection projection is arranged at right side midline position and connecting groove axial symmetry on left side.
Preferably, described guiding gutter is uniform to be arranged on this outside of arc-shaped building block, and described guiding gutter width is 5 ~ 10mm, and the degree of depth is 5 ~ 10mm.
Preferably, the described through hole through upper surface and lower surface is provided with two rows by arc-shaped building block body radial direction, and often arranges and be uniformly provided with 10.
A kind of Anti-permeation concrete manhole many rounds building block of technical solutions of the utility model, to change in prior art outside manhole body of wall moisture content by penetrating in manhole in building block, wash away the cement in manhole building block and building block, glue etc. for a long time, have a strong impact on quality and the life-span of manhole, very easily cause manhole avalanche even to cause casualties; Impervious building block of the present utility model, the lateral surface of the arc-shaped building block body of circular inspection well arranges guiding gutter, when moisture content outside manhole metope enters in building block, moisture content can be pooled in guiding gutter, and flow downward along guiding gutter, moisture content can not ooze inside building block or in manhole along the gap of manhole neighbouring two building block times, avoids moisture content washing away or soaking the cement in building block or building block gap or glue; The upper surface of arc-shaped building block body and lower surface are arranged respectively to convex surface and concave surface, ensure that further a small amount of moisture content entered in manhole building block is flowed out by the inclined plane on convex surface and concave surface, then to flow into bottom manhole in bottom surface along guiding gutter; Impervious building block of the present utility model, ensure that moisture content can not stop in manhole building block, moisture content more can not enter into block interiors, to building block and the cement of building block aperture time and the immersion of glue, can not improve security performance and the application life of manhole.
The utility model technology beneficial effect:
A kind of Anti-permeation concrete manhole many rounds building block of technical solutions of the utility model, building block, when assembling manhole, connects position location many, easy to operate, the reduction of erection time; The building block of the utility model scheme, can prevent moisture content from infiltrating from multiple side and multiple angle, adopt the manhole that this building block assembles, seepage control of wall is functional, and manhole general safety performance is good, long service life.
