Engineering characteristics
(1) The red line of land requisition in this project only exceeds the projection of the collision wall outside the bridge deck by 2.0m. In order to reduce the project investment, the construction site is arranged in the infrared range, and the site is narrow, so it is difficult to arrange temporary facilities such as construction access roads.
(2) Planning the road to cross the Guangzhou-San Railway, the Shiweitang branch line and the place where it passes needs to be constructed on the existing line without interrupting the traffic, so the construction safety is difficult.
(3) There are precast 50m, 30m T-beams, 20m hollow slab beams and cast-in-place special-shaped slab beams in this bid section, and the beam types are diverse, the number is scattered, the pile diameter is not uniform, and it is difficult to use machinery.
(4) The girder erection is large, and the girder fabrication site is small. Making and erecting beams are the key control projects in this bid section, and it is necessary to carefully organize and reasonably arrange the construction of bored piles, piers, capping beams and making beams.
⑤ Short construction period and high quality requirements.
