Infilled wall body filler 10 in the holding tank forming in the inner side of side slope 13, concrete foundation 4 and FRP wall body front panel 1.
Because FRP wall body front panel 1 has higher toughness and intensity; between FRP wall body front panel 1 and side slope 13, be provided with wall body filler 10; when FRP wall body front panel 1 elastic deformation; to the wall body filler 10 between itself and side slope 13, exert pressure; elastic buffer effect by wall body filler 10 can be offset impact force; there is good shock effect of energy dissipation, protection vehicle and internal staff's safety.
In order to increase greenbelt, improve the use value of highway spats wall, in step S1, be specially: manufacture spats wall FRP overall structure, spats wall FRP overall structure comprises FRP wall body front panel 1 and FRP greening retaining casing 3, and FRP greening retaining casing 3 tops are provided with opening; In step S3, also comprise: FRP greening retaining casing 3 is arranged between FRP wall body front panel 1 and side slope 13; Step S4 is specially: between FRP wall body front panel 1 and side slope 13, add wall body filler 10, wall body filler 10 is covered in the concrete top of FRP greening retaining casing 3 and the 2 interior fillings of FRP opening casing.FRP greening retaining casing 3 has and supplies water and two kinds of effects of water storage: at wall body filler 10 interior moisture when less, moisture is supplied water to wall body filler 10 by the opening of the top setting of FRP greening retaining casing 3, keep it to there is certain humidity, to the plant being planted on wall body filler 10, supply water; At wall body filler 10 interior moisture when more (extraneous rainwater etc. enter wall body filler 10), the opening that moisture is arranged to the top of FRP greening retaining casing 3 by wall body filler 10 is carried water, stores moisture to supply water when less at wall body filler 10 interior moisture.
Before step S4, also comprise: to the interior interpolation distributing bar of FRP opening casing 2, to FRP opening casing 2 interior concretings.By to the interior interpolation distributing bar of FRP opening casing 2 and concreting, effectively improved the intensity after FRP opening casing 2 concretings, because it is arranged between FRP greening retaining casing 3 and FRP wall body front panel 1, avoid the damage to FRP greening retaining casing 3 when FRP wall body front panel 1 is subject to clashing into, guaranteed the safety in utilization of FRP greening retaining casing 3; And, improved the intensity of the highway spats wall that the present embodiment provides.
Further, the concrete that FRP opening casing 2 is built reaches after intensity, and between adjacent two sections of described spats wall FRP overall structures, joint arranges and pastes FRP plate connection seam; Seam bonding agent reaches after intensity, by building the gap between bonding adjacent two the spats wall FRP overall structures of joint cast-in-situ concrete 7.Globality and the intensity of the highway spats wall that the present embodiment provides have been improved.
In step S1, be specially: manufacture spats wall FRP overall structure, spats wall FRP overall structure comprises FRP wall body front panel 1, FRP greening retaining casing 3, FRP opening casing 2 and FRP diaphragm 5, FRP greening retaining casing 3 tops are provided with opening, FRP opening casing 2 be arranged at FRP greening retaining casing 3 and FRP wall body front panel 1 between, FRP opening casing 2 opening up, the side of FRP diaphragm 5 is connected with FRP wall body front panel 1, and the base of FRP diaphragm 5 is connected with FRP greening retaining casing 3.Be after FRP wall body front panel 1, FRP opening casing 2, FRP greening retaining casing 3 are in turn connected into one and and FRP diaphragm 5 is bonding is connected, form spats wall FRP overall structure.
Further, in step S1, also comprise: manufacture FRP grid 11; After step S4, also comprise step: FRP grid 11 is arranged to wall body filler 10 tops, FRP grid 11 is connected with the top of FRP wall body front panel 1 and the top of FRP diaphragm 5.FRP grid 11 has first side for being connected with FRP diaphragm 5 and second side for being connected with FRP wall body front panel 1.At wall body filler 10, be filled between FRP wall body front panel 1 and side slope 13 and complete after greening, Qi top covers FRP grid 11, FRP grid 11 first side is connected with FRP diaphragm 5, FRP grid 11 second side is connected with FRP wall body front panel 1, covers the wall body filler 10 after filling.
Before step S4, also comprise step: in the opening of FRP greening retaining casing 3, add the FRP muscle 8 that is enclosed with geotextiles, and cover rubble french drain 9 on FRP greening retaining casing 3, make FRP muscle 8 be wrapped with the lower geotechnological layer of cloth that geotextiles afforests retaining casing 3 near upper geotechnological layer of cloth and the rubble french drain 9 of wall body filler 10 near FRP with rubble french drain 9 and be connected;
FRP greening retaining casing 3 has and supplies water and two kinds of effects of water storage: at wall body filler 10 interior moisture when less, moisture is supplied water to wall body filler 10 by the opening of the top setting of FRP greening retaining casing 3, keep it to there is certain humidity, to the plant being planted on wall body filler 10, supply water; At wall body filler 10 interior moisture when more (extraneous rainwater etc. enter wall body filler 10), the opening that moisture is arranged to the top of FRP greening retaining casing 3 by wall body filler 10 is carried water, stores moisture to supply water when less at wall body filler 10 interior moisture.The top side wall of FRP greening retaining casing 3 is provided with the tapping pipe 6 of downward-sloping layout, and tapping pipe 6 passes FRP wall body front panel 1 away from one end of FRP greening retaining casing 3.At FRP greening retaining casing 3 interior water capacities, when excessive, water leaks near a side of highway to FRP wall body front panel 1 by tapping pipe 6, and draining is to roadside ditch.
Because tapping pipe 6 passes FRP wall body front panel 1 away from one end of FRP greening retaining casing 3, and be provided with FRP opening casing 2 between FRP greening retaining casing 3 and FRP wall body front panel 1, tapping pipe 6 is successively through FRP opening casing 2 and FRP wall body front panel 1.When FRP opening casing 2 interior distributing bar, tapping pipe 6 is installed, is made tapping pipe 6 through FRP opening casing 2 and FRP wall body front panel 1, then to the 2 interior cast-in-situ concretes of FRP opening casing, complete construction.
Preferably, tapping pipe 6 is FRP tapping pipe.Can use PVC tapping pipe, concrete tapping pipe material type does not limit yet.
After step S4, also comprise step: the green plants 12 of planting on wall body filler 10 surfaces.
The main beneficial effect of highway pin wall construction job practices that the utility model embodiment provides is: spats wall adopts the method that factory manufactures and on-the-spot installation combines, and quick construction is convenient.
In the present embodiment, concrete job practices is as follows:
