In order to achieve the second object, the invention has the technical scheme that: the method for simultaneously constructing the comprehensive pipeline and the pile foundation in close distance arrangement is characterized by comprising the following steps,
step 1: determining the positions of the comprehensive pipeline and the pile foundation, inserting and driving a steel sheet pile between the pile foundation and the comprehensive pipeline, and inserting and driving a steel casing at the position of the pile foundation; inserting and driving the steel sheet piles and the steel casing to the lower hard stratum and exceed the elevation of the comprehensive pipeline;
step 2: excavating a foundation pit at the position of the comprehensive pipeline, and simultaneously drilling a hole in the steel casing;
and step 3: constructing a comprehensive pipeline, and simultaneously drilling a steel casing;
and 4, step 4: after the construction of the comprehensive pipeline is finished, backfilling the foundation pit, pulling out the steel sheet pile and pouring a pile foundation;
and 5: and finishing foundation pit filling and pile foundation construction.
In the above technical scheme, in the step 2, a rotary drilling rig or a manual drilling rig is selected for drilling the pile foundation.
The invention adopts effective measures to ensure that the comprehensive pipeline and the pile foundation are simultaneously and smoothly constructed, effectively shortens the construction period of the project, avoids the staged construction of the comprehensive pipeline and the pile foundation, avoids the repeated excavation of the ground, simplifies the construction process of the project, avoids the risk of damaging the constructed structure by the repeated excavation, greatly reduces the construction cost and effectively reduces the influence on the environmental quality due to the repeated excavation.

Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are not intended to limit the present invention, but are merely exemplary. While the advantages of the invention will be apparent and readily appreciated by the description.
With reference to the accompanying drawings: closely arrange the structure of synthesizing pipeline and pile foundation, its characterized in that: comprises an upper soft stratum 11, a lower hard stratum 12 and a steel casing 2; the steel casing 2 is arranged at intervals, the middle part of the steel casing 2 is positioned in an upper soft stratum 11, the lower part of the steel casing 2 is positioned in a lower hard stratum 12, and a pile foundation 21 is poured in the steel casing 2; a comprehensive pipeline 3 is arranged in the upper soft stratum 11; the comprehensive pipeline 3 is positioned on two sides of the steel casing 2.
The method for simultaneously constructing the comprehensive pipeline and the pile foundation in close distance arrangement is characterized by comprising the following steps,
step 1: determining the positions of the comprehensive pipeline 3 and the pile foundation 21, inserting and driving a steel sheet pile 4 between the pile foundation 21 and the comprehensive pipeline 3, and simultaneously inserting and driving a steel casing 2 at the position of the pile foundation 21; the steel sheet pile 4 and the steel casing 2 are inserted into the lower hard stratum 12 and exceed the elevation of the comprehensive pipeline 3;
step 2: excavating a foundation pit 5 at the position of the comprehensive pipeline 3, and simultaneously drilling a hole in the steel casing 2;
and step 3: constructing a comprehensive pipeline 3, and simultaneously drilling the steel casing 2;
and 4, step 4: after the construction of the comprehensive pipeline 3 is finished, backfilling the foundation pit 5, pulling out the steel sheet pile 4 and pouring a pile foundation 21;
and 5: and after the foundation pit 5 is filled and the pile foundation 21 is constructed, the steel casing 2 is not recovered and is permanently reserved.
