Specific embodiment
The feature of the utility model and other correlated characteristics are described in further detail by example below in conjunction with attached drawing,
In order to the understanding of technical staff of the same trade.
The utility model is a kind of precast assembly cable type pipe gallery of rapid construction, is spliced by several segments pre-groove
It forming, it mainly includes U-shaped groove 1, cover board 2, inner sleeve and cuff 4, fixed cuff angle steel 3, fixes tube coupling steel plate 5,
Be characterized in that: U-shaped groove 1 is constructed using precast assembly mode, and inner sleeve is directly laid in trench interiors, and according to shining casing
Diameter, according to certain sequential arrangement.Wherein 150mm casing is arranged in U-shaped trench floor side, 50mm and 100mm casing
It is deposited in the U-shaped trench floor other side.Casing and U-shaped groove 1 are connected by cuff 4 and fixed cuff angle steel 3 every a distance
It connects.
1 wall thickness of U-shaped groove of the Pipe rack of the utility model is 60mm, base plate thickness 100mm, 2 thickness 60mm of cover board.
Recess is set on the inside of the side wall upper part of U-shaped groove 1, and cover board directly rests on U-shaped groove, at the top of the cover board and side of U-shaped groove 1
It is flushed at the top of wall.Every section of pre-groove longitudinal length is 3m, longitudinal to be connected using fixed tube coupling steel plate 5, and fixed tube coupling steel plate 5 divides
It She Zhi not be below U-shaped groove two sidewalls inside upper part, cover board.Bolt connecting hole 6 there are two being set on fixed tube coupling steel plate 5, it is U-shaped
Corresponding bolt connecting hole is reserved on trenched side-wall, is fixed in two bolt connecting holes 6 of tube coupling steel plate 5, one is round hole,
Another is oblong hole, and oblong hole can be used for adjusting bolt setting position, to complete fixed tube coupling steel plate 5 and corresponding two
Save the connection between U-shaped groove.Piping lane inner sleeve internal diameter is that 50mm-150mm is differed, according to certain sequential arrangement.Piping lane
Inner sleeve is also spliced by several segments casing, is connected between adjacent casing using Push-fit.
1 bottom plate of type groove installs fixed cuff angle steel 3, and the fixed cuff angle steel 3 is L-shaped structure, the fixed cuff
One end of angle steel 3 is bolted on U-shaped 1 bottom plate of groove, and the other end is then used to connect band-like stainless steel sleeve hoop, utilizes band
Shape stainless steel cuff, by casing and fixed cuff Bolted angle connection, connecting portion should be staggered with casing bell and spigot position as far as possible, if
It is placed in casing general place.Fixed cuff is made of stainless steel band, has the function of tightening.The width of band-like stainless steel cuff
For 20mm.Cuff must not make casing deform as far as possible close to sleeve outer wall.
Cable piping lane external dimensions is width 60cm, and high 40cm, top road pavement thickness 10cm, buried depth is shallower, can be used
Vertical channel, groove width 1m, groove depth 0.6m.10cm sand bedding course is spread in bottom after fluting.Since buried depth is shallower,
More than general area level of ground water, waterproof measure can not be used.
The concrete construction method of the utility model is described as follows: (1) the U-shaped groove of prefabricated piping lane and cover board in factory are supported
