Abstract
The invention discloses a bridge external anti-collision guardrail. The bridge external anti-collision guardrail comprises protective cableways, a plurality of steel chisels and a plurality of sleeves. The sleeves are embedded into the edge of an anti-collision guardrail formwork, the bottoms of the steel chisels are inserted into the sleeves, and the protective cableways are arranged between the adjacent steel chisels. A method for carrying out construction through the bridge external anti-collision guardrail is provided. The method includes the following steps that during first-time use, a constructor enables the two cableways to penetrate through round holes in the top ends and the middles of the steel chisels, and the steel chisels are connected together in series; the steel chisels are inserted into the sleeves; the two ends of each of the two cableways are fixed to the formwork through buckles, and the cableways are straightened; when guardrail concrete is poured, the constructor wears a safety belt, buckles a hanging buckle of the safety belt on the cableways and walks front and back along the cableways, and the concrete is poured; after the guardrail concrete is poured, the buckles are taken down, the steel chisels are pulled out of the sleeves, and safety and convenience of aloft work can be guaranteed.
Description
Technical field
The present invention relates to the outer guardrail construction field of bridge, particularly the outer anticollision barrier of a kind of bridge and safe construction method thereof.
Background technology
In the outer anticollision barrier work progress of bridge, guardrail concreting is a dangerous job, belongs to work high above the ground.General anticollision barrier height is all at about 1.2 meters, and concreting, when vibrating, the template that constructor needs to stand in anticollision barrier is constructed, safety belt is put in common safety precautions, but when concrete pouring construction, constructor will move in template, very inconvenient.
Summary of the invention
Technical problem to be solved by this invention is to provide the outer anticollision barrier of a kind of bridge and safe construction method thereof, can ensure high-altitude working safety, convenient, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technical scheme: the outer anticollision barrier of a kind of bridge, comprise protection cableway, drill rod and sleeve pipe, described sleeve pipe is provided with multiple, it is embedded in the edge of crash barrier template, drill rod is provided with multiple, inserts in sleeve pipe bottom it, and protection cableway is arranged between adjacent drill rod.
Preferably, described protection cableway arranges twice altogether, is made up of two hawsers.
Preferably, the two ends of described hawser arrange buckle, and the sidewall of described drill rod is provided with multiple circular hole, and buckle is stuck in circular hole.
Preferably, the bottom of described drill rod is exceeding position reinforcement welding kelly of sleeve pipe.
Use the outer anticollision barrier of bridge to carry out a method of constructing, comprise the following steps:
1), when using first, constructor is each passed through the circular hole at drill rod top and middle part with two cableways, is cascaded by drill rod;
2) before guardrail concreting, according to the position of sleeve pipe, drill rod is inserted in sleeve pipe, ensures that the height that drill rod exceeds template is 1.2m;
3) the two ends buckle of two cableways is fixed in template, and makes cableway exceptionally straight;
4) when building guardrail concrete, constructor has worn safety belt, and is buckled on cableway by buckling of safety belt, and constructor walks before and after cableway, concreting;
5) after guardrail concreting completes, take off buckle, drill rod is extracted in sleeve pipe, the drill rod being installed with cableway is deposited, when using next time, directly drill rod can be inserted in sleeve pipe and continue to use.
The beneficial effect of above technical scheme is adopted to be: the outer guardrail construction safety protection of bridge of the present invention, make constructor when ensureing safety, can move along cableway, make the construction of bridge outer guardrail very convenient, do not need, by buckling unloading back and forth, hang up on safety belt, in the outer guardrail high-altitude working safety of guarantee bridge, to provide a kind of well method.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the view that it uses.
Wherein, 1--crash barrier template, 2--hawser, 3--drill rod, 4--sleeve pipe, 5--buckle, 6--circular hole, 7--safety belt, 8--safety belt buckle.
Detailed description of the invention
The preferred embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the specific embodiment of the present invention: the outer anticollision barrier of a kind of bridge, comprise protection cableway, drill rod 3 and sleeve pipe 4, described sleeve pipe 4 is provided with multiple, it is embedded in the edge of crash barrier template 1, drill rod 3 is provided with multiple, insert in sleeve pipe 4 bottom it, protection cableway is arranged between adjacent drill rod 3.
Protection cableway arranges twice altogether, is made up of two hawsers 2; The two ends of hawser 2 arrange buckle 5, and the sidewall of described drill rod 3 is provided with multiple circular hole 6, and buckle 5 is stuck in circular hole 6; The bottom of drill rod 3 is exceeding position reinforcement welding kelly of sleeve pipe 4.
The cableway used in guard cable adopts the chemical fibre hawser 2 that diameter is 8mm, has the advantages that intensity is high, wear-resisting; Drill rod 3 round steel that diameter is 20mm is made, and round steel is cut into the rod member that length is 1.4m.In one end of rod member, the position of distance termination 20cm, in the vertical direction of rod member, the reinforcing bar of a welding long 5cm.In the other end of rod member and the position of distance termination 60cm, each welding internal diameter is the annulus of 14mm; The internal diameter of sleeve pipe 4 is 22mm, is highly 20cm, is welded on the outside of guardrail template, and the top mouth of sleeve pipe 4 is equal with template; The position needing welding used, requires firm welding.
Use the outer anticollision barrier of bridge to carry out a method of constructing, comprise the following steps:
1), when using first, constructor is each passed through the circular hole 6 at drill rod 3 top and middle part with two cableways, is cascaded by drill rod 3;
2) before guardrail concreting, according to the position of sleeve pipe 4, be inserted into by drill rod 3 in sleeve pipe 4, the height that guarantee drill rod 3 exceeds template is 1.2m;
3) the two ends buckle 5 of two cableways is fixed in template, and makes cableway exceptionally straight;
4) when building guardrail concrete, constructor has worn safety belt 7, and safety belt is buckled 8 on cableway, and constructor walks before and after cableway, concreting;
5) after guardrail concreting completes, take off buckle 5, drill rod 3 is extracted in sleeve pipe 4, the drill rod 3 being installed with cableway is deposited, when using next time, directly drill rod 3 can be inserted in sleeve pipe 4 and continue to use.
The outer guardrail construction safety protection of bridge of the present invention, make constructor when ensureing safety, can move along cableway, make the construction of bridge outer guardrail very convenient, do not need, by buckling unloading back and forth, hang up on safety belt, in the outer guardrail high-altitude working safety of guarantee bridge, to provide a kind of well method.
