Water hole undergauge occurs, it is to avoid the generation in temperature change harmomegathus crack, reduces on-site construction processes, is easily repaired after damage, together
When also beneficial to scene safety construction.
Background technology
Often construction is completed at the scene for tunnel and other underground engineering gutters, and Specific construction operation includes colligation steel
Muscle-formwork supporting plate-casting concrete-vibrate-conserve the working procedures such as shaping.Cast-in-place integral gutter easily produce with
Lower problem：1st, because construction site condition is limited, easily there are various mass defects in cast in situs gutter, such as losing fangle, rise
Husky scaling, voids and pits, slag inclusion, cavity, insufficient or cross to shake of vibrating isolation, reinforcing bar transposition, protective layer thickness deficiency and section
Error etc..2nd, because construction site condition is limited, osculum undergauge is also easy to produce, influences the drainability of gutter.3rd, scene
Pour monoblock type gutter general more long, temperature change easily produces harmomegathus crack.4th, cast-in-place integral gutter
Due to needing site operation and maintenance, construction speed is influenceed.5th, cast-in-place integral gutter is unfavorable for the safety at scene
Civilized construction.6th, cast-in-place integral gutter is poured again if any generation seepage, reparation is damaged after need to cutting damaged section
Construction, operation is more complicated.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of simple and practical prefabricated assembled tunnel drainage side
Ditch.
A kind of prefabricated assembled tunnel drainage gutter, be prefabricated in the factory completion, after the good reinforcing bar of factory's colligation, pours coagulation
Soil, vibrating and conserving is formed, including water leg, osculum and prefabricated casting concrete, and an inverted trapezoidal collection is stayed on gutter top
Tank, is flowed to the surface gathered water at gutter and is flowed in osculum by water leg, is then discharged out.
Further, gutter side is concave head, and opposite side is plush copper, and the plush copper of upper section gutter is embedded in lower section gutter
Concave head, and concavo-convex head seam crossing smear waterproofing tack coat.
Further, the lateral middle gradient in gutter upper surface two is 1~4%, gutter single-unit length range
It is 50~200cm.
Further, the inverted trapezoidal water leg top is beneficial to than lower hem width and catchments.
Further, the inverted trapezoidal is isosceles trapezoid, and trapezoidal oblique angle is 60~75 °.
Further, the osculum is circle, and radius is 10~20cm.
Further, the head fall of the gutter is identical with road gradient.
Compared with prior art, prefabricated assembled tunnel drainage gutter described in the utility model has the following advantages that：It is logical
Cross batch production prefabricated, various mass defects can be prevented effectively from and forming errors are reduced；Osculum undergauge is avoided to occur, it is ensured that draining
Ability；The seam of prefabricated assembled gutter avoids the generation in temperature stress harmomegathus crack；Reduce on-site construction processes and
Curing time, accelerates speed of application；After breakage, damaged section, process is simple and short time limit are directly changed.
Brief description of the drawings
Fig. 1 is the prefabricated assembled gutter schematic cross-sectional view of the utility model.
Fig. 2 is the prefabricated assembled gutter concave head structural map of the utility model.
Fig. 3 is the prefabricated assembled gutter plush copper structural map of the utility model.
In figure：Water leg -1, osculum -2, prefabricated casting concrete -3.
Specific embodiment
The utility model provides a kind of simple and practical prefabricated assembled tunnel drainage gutter, including water leg 1, draining
Hole 2 and prefabricated casting concrete 3 etc., be prefabricated in the factory completion, after the good reinforcing bar of factory's colligation, casting concrete, vibrates and supports
Shield is formed.An inverted trapezoidal water leg is stayed on gutter top, is flowed to the surface gathered water at gutter and is flowed to row by water leg
In water hole, it is then discharged out.Gutter side is concave head, and opposite side is plush copper.The plush copper of upper section gutter is embedded in lower section gutter
Concave head, and concavo-convex head seam crossing smear waterproofing tack coat.The gradient in the middle of gutter upper surface two is lateral is 1~4%,
Gutter single-unit length is according to single-unit gutter weight and the determination of mechanization of building operation degree, generally 50~200cm；The ladder
Catchmented than following slightly wide being beneficial to shape groove top；The inverted trapezoidal is isosceles trapezoid, and trapezoidal oblique angle is 60~75 °；Osculum is
Circle, radius is 10~20cm according to flow.The head fall of gutter is identical with road gradient.
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings：
As shown in figure 1, the prefabricated assembled gutter of the utility model it is main by water leg 1, osculum 2, prefabricated pour
