Background
Along with the rapid development of economy, the requirements for basic construction engineering, particularly mountain road traffic engineering, are more and more increased, and the road traffic engineering has more and more construction requirements for bridge construction due to the characteristics of narrow and changeable mountain terrain space. The pile foundation construction is an essential important procedure in bridge construction, and the pile foundation construction method comprises precast pile construction, cast-in-place pile construction and the like. The existing problems of high construction difficulty, high labor cost, large influence on ecological environment and the like of the traditional pile foundation construction cannot meet the construction requirements of bridge construction in the current mountain narrow space, and new high-efficiency environment-friendly pile foundation construction equipment needs to be developed.
In the existing viaduct construction including traffic roads, transportation pipelines and other projects, in order to accelerate the progress, a construction method for splicing prefabricated parts is increasingly adopted. In the construction method, the premise of the work of the bridge fabrication machine is that the lower pile foundation is driven in advance.
The pile foundation construction method comprises precast pile construction, filling pile construction and the like, wherein the precast pile construction is realized by driving precast reinforced concrete piles into the ground, and has the advantages of material saving, high strength, high construction difficulty and long construction time, and is not suitable for filled land and difficult to drive into hard geology; the bored concrete pile construction firstly needs to drill holes on a construction site, and when the required depth is reached, steel bars or I-shaped iron are put into and poured with concrete, so that the construction difficulty is low compared with that of precast piles, the pile can be manually dug, a plurality of pile foundations can be simultaneously constructed after the pile is dug, and the time is compressible. In the case of the pouring construction method, a drilling machine pile or a manual pile is mostly used. The conventional drilling machine has high requirements on the field, the equipment transportation needs to be provided with a construction passageway, the construction passageway is greatly limited by the terrain, and the construction cost is high. The manual hole digging construction efficiency is low, and the danger coefficient is large. Therefore, the difficulty of bridge pile foundation construction in the complex terrain environment of the mountain area is high, the cost is high, and the efficiency is low, which are not bearable by the construction side, no matter the traditional precast pile construction or the traditional cast-in-place pile construction.
On bridge pile foundation construction equipment, pile foundation pore-forming devices are focused on the design of pore-forming drill bits as described in patent document CN209603117U, CN207453874U, CN108952586A, so that the problem of pore-forming is solved, and the problem of pile foundation construction under different terrains cannot be solved. In patent document CN209539259U, a hoist is provided for the hole forming device to complete the transfer of the hole forming slag, and the solution for construction under complex topography is not provided.
In order to solve the problem of terrain limitation, as disclosed in patent document CN201921824290.6, a suspended self-supporting pile driver is provided, which comprises a bridge erecting mechanism, a pile driving mechanism and a folding mechanism, and can realize suspended pile driving operation, but can only hammer common precast piles on a soft soil foundation. As disclosed in patent document CN113216176a, the device comprises a bridge erecting mechanism, a pile driving and hole guiding integrated device and a pile lifting crown block, wherein two pile driving devices of hammering and hole guiding can be arranged on the bridge erecting mechanism, so that suspended self-supporting bridge erecting and hole guiding hammering pile driving is realized, and the device can be suitable for pile driving and pile sinking construction by a hole guiding hammer on a hard soil layer foundation. But lacks support for other construction methods, such as a cast-in-place pile construction method, and the like, and cannot adapt to various geological pile foundation constructions.
