Middle arrangement facilitates pipeline performance management and plant maintenance, can avoid causing road surface to repeat to excavate due to embedded or repair pipeline
Caused trouble, and can also be extended to the service life of pipeline to avoid soil to the corrosion failure of pipeline.
Between the piping lane segmentation of traditional cast-in-place making, using rubber water-proof band connection, the anti-ground of interface of the form is not
Uniform settlement energy force difference, waterstop is yielding, or even by drawing crack.The prefabricated city piping lane technology occurred in recent years is quickly grown,
But also there is similar sealing problem between tube coupling, just at present, the common rubber fastening band interface of piping lane is extremely difficult to use one
Century-old index；All it is that rubber fastening band is directly enclosed in joint simultaneously as when pouring, when damage, can not carries out
It replaces.
Invention content
It is to be solved by this invention to be exactly between the segmentation of existing piping lane, using rubber water-proof band connection, waterstop is fragile,
Difficult problem is replaced, a kind of replacement convenience, pipe gallery boss sealing structure with long service life are provided.
The pipe gallery boss sealing structure of the present invention, is arranged in the junction of two sections of adjacent piping lanes, it is characterised in that
The structure includes notch, sealing element and seal groove, and notch is arranged on the end face at piping lane both ends, seal groove setting piping lane its
Middle one end, and positioned at the bottom of the gap of the end face；After adjacent two sections of piping lanes connection, opposite two notches synthesize a groove,
Sealing element is placed in groove；The sealing element includes shrinking rubber and hydro-expansive rubber, and contraction rubber is rectangular, inside setting
Hole, hydro-expansive rubber are arranged on four, the upper and lower, left and right face for shrinking rubber；Fill concrete in seal groove.
It is provided with embedded board, other end built-in metal in the piping lane wherein vertical inner wall of the seal groove of one end setting
Sealing rod, the metallic water stop section are in wavy, and half is embedded in piping lane, another semi-convex piping lane end face, two sections of piping lanes
When connection, one end that first segment piping lane is provided with metallic water stop item is provided with one end of seal groove with second segment piping lane and connect, gold
Belong to sealing rod and protrudes from being partly embedded in the seal groove of second segment piping lane of first segment piping lane end face.
It is additionally provided with backfill layer inside the seal groove, backfills and is provided with grout pipe on layer, grouting tube opening setting exists
It, can the backfill such as perfusion epoxy resin mortar into backfill layer by grout pipe when sealing element sealing effect is bad outside seal groove
Object enhances sealing effect.
Boss is additionally provided on the hydro-expansive rubber, boss groove contacts to form sealing line, linear using sealing
At sealing.
It is welded with embedded board the end of the metallic water stop item protrusion.
Sealing element, metallic water stop item and embedded board carry out prefabricated, such as round, rectangular or arch door shape all in accordance with piping lane form
Deng, sealing element is placed in the groove formed after adjacent two sections of piping lanes connection, it is annular to sealing using the inner space of groove
At certain protection, its service life is improved, while sealing effect is improved by corrugated metallic water stop item, and utilize coagulation
Groove where native close encapsulation groove and sealing element, and setting can fill the backfill of backfill object sealing at any time in seal groove
Layer, effectively increases the sealing effect between piping lane.
The pipe gallery boss sealing structure of the present invention, simple in structure, design science is easy to use, and sealing element is placed
In groove, the service life of sealing element is effectively increased, and sealing effect is provided by sealing element and seal groove, and sealing
Setting backfill layer, provides sealing compensation measure, ensure that sealing effect in slot.
