[0003]On the premise that the bearing capacity and overall stability of steel sheet piles meet the design requirements, steel sheet pile support is popular due to its advantages of low cost, material turnover and convenient construction , but under the condition of soil strata (including boulders), the construction of steel sheet piles is limited, and the construction period of steel sheet piles will be greatly extended.
Other deep foundation pit steel sheet piles (such as row piles (bored piles) support, row piles + water-stop curtain support, SMW pile support, etc.) have high costs and long construction periods. It is difficult to apply to construction projects with a large amount of structural engineering

The invention discloses a bridge pile and supporting steel sheet pile synchronous construction method. The method comprises the following steps that S1, bridge piles are divided into a plurality of to-be-constructed bridge piles A and a plurality of constructed bridge piles B, and the to-be-constructed bridge piles A and the to-be-constructed bridge piles B are distributed at intervals; and S2, a drilling machine is moved to the position of one to-be-constructed bridge pile A, and the to-be-constructed bridge pile A is constructed, and meanwhile, the end, away from the to-be-constructed bridge pile A by the preset distance, of the bridge pile A is selected as a steel sheet pile driving starting point, and steel sheet pile driving is conducted within the preset range from the steel sheet pile driving starting point. According to the construction method, the steel sheet piles and part of the bridge piles are constructed at the same time in a sectioned mode, construction of the steel sheet pile supporting structure is completed while construction of all the bridge piles is completed, multiple working faces are constructed at the same time, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to the field of bridge foundation construction. More specifically, the present invention relates to a method for synchronous construction of bridge piles and steel sheet piles. Background technique [0002] In recent years, in the process of bridge foundation construction at home and abroad, for different geological conditions, the main forms of land bridge buried cap deep foundation pit support are: row pile (bored pile) support, steel sheet pile support, Underground Diaphragm Wall Support, Pile Row + Waterstop Curtain Support, SMW Construction Method Pile Support, etc. And the general construction sequence of bridge land foundation is: bored pile construction → foundation pit support construction → foundation pit excavation → platform cap construction, in which bridge piles and steel sheet piles are constructed in sequence. [0003] Under the premise that the bearing capacity and overall stability of steel sheet piles meet the...
