The Intercepting Drain Used in Highway that the embodiment of the invention provides, comprise the catchwater body, comprise the FRP base plate casing 1 of the bottom that is positioned at the catchwater body and lay respectively at the FRP web casing 2 of the both sides of catchwater body, wherein, the FRP web casing 2 of catchwater body both sides all tilts to the outside of catchwater body, and the width at the top of formation catchwater body is greater than the inverted trapezoidal structure of bottom width.
Wherein, the English full name of FRP is Fiber Reinforced Polymer, and Chinese is fibre reinforced composites.Fibre reinforced composites were called GFRP(and often claim glass fiber reinforced plastic when fiber adopted glass fiber), fibre reinforced composites were called CFRP when fiber adopted carbon fiber, and GFRP and CFRP are designated hereinafter simply as FRP.About glass fiber tensile strength 1000MPa, about epoxy resin tensile strength 60MPa, glass fiber and epoxy resin can reach about 300MPa in conjunction with back formation GFRP structural strength and steel structure intensity approaches.About tensile strength of carbon fibers 3000MPa, carbon fiber and epoxy resin form CFRP intensity in conjunction with the back and is much higher than steel structure intensity, but the carbon fiber cost is higher, and is uneconomical.The GFRP water resistance is good, the GFRP less expensive, and FRP base plate casing and FRP web casing are all adopted in easy construction in the Intercepting Drain Used in Highway provided by the invention, have favorable waterproof property, and have the advantage from heavy and light.
Simultaneously, because what adopt is FRP base plate casing 1 and FRP web casing 2, the equipment that belongs to moulding, during use, need to use multistage FRP base plate casing 1 and FRP web casing 2, joint concreting can directly be carried out at the scene in the joint of two adjacent FRP base plate casings 1 and FRP web casing 2 so, and is simple and convenient, reduce the template usage quantity, and shortened the engineering time.
Need to prove, in this specific embodiment, can adopt high 40 centimetres FRP web casing 2 all to spend 40 centimetres of this heights of catchwater to the outside inclination 45 of catchwater body in the catchwater body, the bottom is wide 40 centimetres, 120 centimetres of the width at the top of catchwater body.
Wherein, FRP base plate casing 1 below is provided with base concrete 3, and FRP base plate casing 1 sticks on the base concrete 3, to strengthen the fixed effect of FRP base plate casing 1, base concrete 3 thickness can adopt 20 centimetres, and transverse width is wide consistent with FRP base plate casing 1 bottom.Certainly, also can adopt other size according to the condition of production of reality.
Wherein, FRP base plate casing 1 and FRP web casing 2 are FRP multicell casing overall structure, and casing case chamber interior filling gap filler, and gap filler is cranny filler of polyurethane foam.Adopt FRP base plate casing 1 and the FRP web casing 2 of integral structure, can further improve speed of application, and, adopt cranny filler of polyurethane foam that it is carried out intensity and consolidate, prevent distortion.In the work progress, FRP base plate casing 1 and FRP web casing 2 are inner not concretings, filled polyurethane foam gap filler when only needing to make, thus further shortened the engineering time.
Need to prove that in this specific embodiment, FRP base plate casing 1 and FRP web casing 2 thickness can adopt high 30 centimetres, the FRP case that wall thickness is 5 millimeters.Certainly, also can adopt other size according to the condition of production of reality.
Wherein, the top of FRP web casing 2 all arranges cast-in-situ concrete 4 and ground, both sides along connecing, and backfill is set in the both sides at the top of FRP web casing 2 and ground is closely connected., before concreting, further FRP web casing 2 is fixed, and appearance effect is better by cast-in-situ concrete 4.
Wherein, the joint, two ends of FRP web casing 2 next-door neighbour ground arranged outside has web substrate concrete 5 and ground closely connected along its length, and FRP web casing 2 sticks on the web substrate concrete 5, to strengthen the fixed effect of FRP web casing 2.Because during actual the use, need multistage FRP web casing 2, so only 5 pairs of FRP webs of the arranged outside web substrate concrete casing 2 on next-door neighbour ground, the joint of two adjacent FRP web casings 2 supports, like this, one place's web substrate concrete 5 can be finished the support to an end of two FRP web casings 2, and, only arrange in the joint, thereby further reduced construction cost.
And in the place except the joint, FRP web casing 2 has the space with on every side ground, at this moment, in the both sides on FRP web casing 2 next-door neighbour ground, middle part along its length backfill is set and ground is closely connected, by backfill these spaces are filled up, further reduced construction cost.
Wherein, also be provided with diaphragm 6 in joint, two ends FRP base plate casing 1 along its length and the casing of FRP web casing 2, be actually that each shares a diaphragm 6 in the casing at the two ends of the two ends of every section FRP base plate casing 1 and every section FRP web casing 2, so, there are two diaphragms 6 joint of adjacent two FRP base plate casings 1 and FRP web casing 2, fill concrete in the casing between two diaphragms 6 of the joint of two adjacent FRP base plate casings 1 along its length so, fill concrete in the casing between two adjacent diaphragms 6 of the joint of two adjacent FRP web casings 2, to guarantee its firm intensity, and diaphragm 6 is set is conducive to concrete filling, can also paste one deck FRP woven roving waterproofing course at the concrete upper surface simultaneously, the short felt of cutting of the one deck of stickup up and down FRP of FRP woven roving, joint FRP base plate casing 1 and FRP web casing 2 chamber interior walls can be pasted the FRP plate and connect, and improve waterproof effect and FRP structural integrity.
Need to prove, in this specific embodiment, diaphragm 6 can adopt 25 centimetres apart from FRP base plate casing 1 and FRP web casing 2 ends, distance is 50 centimetres between the adjacent diaphragm 6 in joint, web substrate concrete 5 distance along its length is 50 centimetres, the web substrate concrete 5 high 20 centimetres get final product, diaphragm 6 can adopt the FRP plate of 5 millimeters of wall thickness.Certainly, also can adopt other size according to the condition of production of reality.
