Pipe typically uses armored concrete material, and reinforcing bar is perishable, and then destroys concrete, and reinforcing bar has electromagnetism sense with transmission line of electricity
Should be so as to producing power consumption；Compared with pervious concrete, normal silicate concrete permeable poor performance, sponge city is unsatisfactory for
Permeable requirement.
Patent 201410750042.7 is related to " a kind of pre-fabricated electric cables comb ", including multiple upper half-round slots and lower half circular groove one
Body formed is upper groove body and lower groove, and upper and lower cell body is spliced to form pre-fabricated electric cables comb.Though this cable duct bank is easy for construction,
It is repeatable to utilize, but when cabling quantity lays underaction less than when accommodating minimum number, the scope of operation is single, so should
With scope by a definite limitation.It is related to " assembled cable duct bank mounting structure " for this point patent 201621081538.0,
Including being provided with the spacing tenon of outer protrusion and the groove for its insertion with hollow cable protection pipe, cable protection pipe side.Should
Though invention can use mechanized construction, can not meet the permeable requirement in sponge city also can not avoid reinforcing bar electromagnetic induction from being made
Into power consumption.
Patent 2012220120088.7 is related to " a kind of split type cable duct bank ", including a kind of split type cable duct bank by
Long Ω types semi-circular tube and short Ω types semi-circular tube are formed, and the utility model is applied due to being to be connected by screw between comb and comb
Work requires high, and this connected mode easily seeps water, corrosion.Now need badly it is a kind of it is easy for construction, repeatable utilize, save electric energy,
Meet the prefabricated assembled cable comb that the infiltration of sponge city requires.
The content of the invention
The purpose of utility model of the present invention be to provide a kind of industrialized production, save electric energy, alleviate municipal drainage pressure, into
The prefabricated assembled FRP tendons pervious concrete cable duct bank that quality is good, speed of production is fast, using factory floor equipment and skill
Art advantage, product quality is improved on the premise of cost is not significantly improved, improve the water penetration of cable duct bank and improve durability.
To achieve these goals, technical scheme is used by utility model of the present invention：
A kind of prefabricated assembled FRP tendons pervious concrete cable duct bank, it is characterised in that：The hollow electricity passed through by current supply cable
Cable comb forms, and stretches out 50mm in longitudinal side FRP tendons of cable duct bank, and as spacing tenon, opposite side is retracted 50mm, as
Spacing blind mortise, 2 FRP lifting muscle are provided with the radial direction side of cable duct bank, is provided with and supplies in the side for setting lifting muscle opposite
Lift the groove of muscle insertion.
Section outside cable duct bank of the present invention is integrally rectangular, the cable duct bank be superimposed by multi-layer cable protection pipe and
Into in spacing FRP sheet material of the both sides of cable duct bank provided with limitation cable duct bank lateral movement of the bottom, the cable of the bottom
The lower end of protection pipe is rested the head on provided with road, and road pillow is placed on blotter.
Each angle of each cable duct bank of the present invention is equipped with chamfering, the star-like breach shape that adjacent four combs are formed
Into a reserved passageway.
The cable duct bank junction diameter increase 10mm that the present invention is connected.
The FRP tendons that the longitudinal direction of the prefabricated assembled FRP tendons pervious concrete mounting structure of the present invention is 4 10 ~ 16mm of diameter
The tensile capacity of FRP tendons can be made full use of strong and corrosion resistance characteristic, effectively solution pervious concrete structural strength are low, easy to crack
The problems such as, the durability of this pervious concrete cable duct bank is fully improved, after longitudinal stress muscle colligation terminates, carries out stirrup
3 colligation, after pouring pervious concrete in mould, conserve 28 days, finished product dispatches from the factory.
Beneficial effects of the present invention and advantage is compared with prior art：Save electric energy, high-durability energy, quick Fabrication
With assembly performance, meet sponge city infiltration require etc..
