Embodiment 1

[0043] Such as Figure 1~11 As shown, a prefabricated bridge safety channel and its construction method include a plurality of bases 1 installed along the road shoulders on both sides of the road. Columns 2 are fixed on the bases 1, and columns 2 are fixed between two adjacent columns 2. Longitudinal beam 6 and scissors strut 4, multiple upper cover plates 3 are fixed on the longitudinal girder 6, the upper cover plate 3 covers both sides of the road on the projection plane, and connecting mechanism 5 is provided between the scissors strut 4 and the column 2 , The scissors strut 4 connects and supports two adjacent columns 2 through a connecting mechanism 5 . Due to this structure, in order to avoid damage to people and objects caused by falling objects falling into the normal road during bridge construction, it is necessary to set up a safety passage on the road under the bridge to ensure the normal passage of people and vehicles. , to avoid long-term construction blocking t...

Embodiment 2

[0056] Such as Figure 1~9 , further illustrate in conjunction with embodiment 1, carry out measurement stakeout to road both sides road shoulder by total station, determine safety passage span, height size; Carry out traffic control, half-width traffic, carry out the base seat 1 installation of safety passage at road both sides road shoulder, The base 1 is filled with discarded concrete test block 106 as a gravity structure, and welded steel bars 105 are added to prevent the concrete test block 106 from moving; the column 2 is installed, and the bottom of the column 2 is inserted into the column mounting seat 103 on the base 1 and passed through the pin The shaft 104 is fixed with the cotter pin, fixed after adjusting the verticality of the column 2, and then the longitudinal beam 6 and the scissors brace 4 are installed, the two ends of the longitudinal beam 6 are fixed on the connecting plate 201 on the column 2 by bolts, The strut 4 is fixedly connected with the column 2 t...

Abstract

The invention provides a fabricated bridge safety channel and a construction method. The fabricated bridge safety channel comprises a plurality of foundations, wherein the plurality of foundations are installed along road shoulders on both sides of a road, stand columns are fixedly arranged on the foundations, longitudinal beams and scissors supporting rods are fixedly arranged between every two adjacent stand columns, a plurality of upper cover plates are fixedly arranged on the longitudinal beams, the upper cover plates cover the both sides of the road on a projection plane, connecting mechanism are arranged between the scissors supporting rods and the stand columns, and the scissors supporting rods are connected with and supports the two adjacent stand columns through the connecting mechanisms. Materials are quickly blended, and unnecessary material loss and the waste of preparation cost in advance are not caused; components in each stage are processed in a field, bolt connection is completed in the field, the space in the field is sufficient, and the entity quality of the components is not influenced by limited high-altitude operation; hoisting equipment is used for realizing fabricated double-working-face construction, so that the construction time is greatly shortened; and the foundations use a lattice type reinforcement cage as a gravity structure, can be quickly moved and mounted, can be recycled and is filled with waste concrete test blocks, so that the effect of waste utilization is achieved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to an assembled bridge safety passage and a construction method. Background technique [0002] With the rapid development of traffic network construction, road space intersection construction is becoming more and more common. In order to ensure the safety of existing roads, safe passages are set to protect road space red lines. During the process of erecting and dismantling safe passages, the lower roads must be closed. Time occupied by the construction of the original line has brought traffic difficulties to local enterprises and residents in their offices and lives; it has brought unnecessary negative impacts on construction companies, so it is necessary to propose a prefabricated bridge safety passage and construction method that can be completed in a relatively short period of time The installation and dismantling of safety passages, while less destructive dismantling methods,...
