Description
Technical Field
The invention relates to the technical field of bridge erection construction and pile foundation construction, in particular to a high-efficiency pile foundation construction hole forming device for a bridge building machine.
Background
Along with the rapid development of economy, the demand on capital construction projects, particularly mountain land road traffic projects is more and more, and the characteristic of the narrow and changeable terrain in mountain land space enables the road traffic projects to emerge more and more bridge construction demands. The pile foundation construction is a necessary important process in bridge construction and bridging, 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 can not meet the bridge construction and bridging construction requirements of the current narrow space of the mountain land, and new high-efficiency environment-friendly pile foundation construction equipment needs to be developed.
In the construction of the existing viaduct including the traffic roads, the transportation pipelines and other projects, a construction method of assembling prefabricated parts is increasingly adopted for accelerating the progress. In the construction method, the premise of the operation of the bridge fabrication machine is to drive the lower pile foundation in advance.
The pile foundation construction method comprises precast pile construction, cast-in-place pile construction and the like, the precast pile construction is realized by driving the precast reinforced concrete pile into the ground, and the method has the advantages of material saving, high strength, high construction difficulty, long construction time, inapplicability to filled land and difficulty in driving into hard geology; the cast-in-place pile construction firstly needs to drill holes in a construction site, after the required depth is reached, reinforcing steel bars or I-shaped iron are placed into the cast-in-place pile and concrete is poured, the construction difficulty of the cast-in-place pile is low, the pile can be manually dug, a plurality of pile foundations can be simultaneously constructed after the hole is dug, and the time can be compressed. In the case of the cast-in-place construction method, a drill pile or a manual pile is often used. The conventional drilling machine is high in requirement on a site for digging holes, construction access is required for equipment transportation, the limitation by the terrain is large, and the construction cost is high. The manual hole digging construction efficiency is low, and the danger coefficient is large. Therefore, no matter the traditional precast pile construction or the traditional cast-in-place pile construction is adopted, the difficulty, the cost and the efficiency of the bridge pile foundation construction in the complex mountain terrain environment are all hard to bear.
On bridge pile foundation construction equipment, such as patent documents CN209603117U, CN207453874U and CN108952586A, pile foundation hole forming devices focus on the design of hole forming drill bits, and are dedicated to solving the problem of hole forming, but fail to solve the problem of pile foundation construction under different terrains. In CN209539259U, a winch is provided for the hole-forming device to transport the hole-forming residue soil, and a solution for construction under complex terrain is also not provided.
In order to solve the problem of terrain limitation, for example, patent document CN201921824290.6 discloses a suspension self-supporting pile driver, which comprises a bridge erecting mechanism, a pile driving mechanism and a folding mechanism, and can realize suspension pile driving operation, but only can hammer a common precast pile in a soft soil foundation. For example, patent document CN113216176A discloses a bridge erecting and pile driving pilot hole integrated device, which comprises a bridge erecting mechanism, a pile driving pilot hole integrated device and a pile hanging crown block, wherein two pile driving devices, i.e. hammering and pilot hole, can be arranged on the bridge erecting mechanism, so that the suspended self-supporting bridge erecting and pile driving by hammering is realized, and the device can adapt to the construction of pilot hole hammering and pile sinking on a hard soil foundation. However, the method lacks support for other construction methods, such as a cast-in-place pile construction method and the like, and cannot adapt to construction of multiple geological pile foundations.
