Abstract
The utility model discloses a closely arrange structure of synthesizing pipeline and pile foundation relates to engineering construction technical field. The device comprises an upper soft stratum, a lower hard stratum and a steel casing; the middle part of the steel casing is positioned in the upper soft stratum, the lower part of the steel casing is positioned in the lower hard stratum, and a pile foundation is poured in the steel casing; the upper soft stratum is provided with a comprehensive pipeline. The utility model discloses the construction cost has greatly been reduced to effectively reduced owing to excavate the influence to environmental quality repeatedly.
Description
Technical Field
The utility model relates to an engineering construction technical field, the more specifically it is a closely arrange structure of synthesizing pipeline and pile foundation that says so.
Background
In some special sections, due to the limitation of arrangement space, urban comprehensive pipelines and structural pile foundations are often in a short distance. The existing urban comprehensive pipelines and the structural pile foundations which are relatively close to each other are usually constructed in stages, one structural object is constructed, the other structural object is constructed, the construction period is long, repeated excavation and repeated protection exist, the construction process is complex, great waste is caused, and the constructed structural object is damaged when the construction process is repeated.
Therefore, it is necessary to provide a structure for arranging the integrated pipeline and the pile foundation at a short distance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the weak point of above-mentioned background art, and provide a closely arrange structure of synthesizing pipeline and pile foundation.
In order to realize the purpose, the technical scheme of the utility model is that: closely arrange the structure of synthesizing pipeline and pile foundation, its characterized in that: comprises an upper soft stratum, a lower hard stratum and a steel casing; the middle part of the steel casing is positioned in the upper soft stratum, the lower part of the steel casing is positioned in the lower hard stratum, and a pile foundation is poured in the steel casing; and a comprehensive pipeline is arranged in the upper soft stratum.
In the technical scheme, the comprehensive pipelines are positioned on two sides of the steel casing.
The utility model discloses take effective measure to make comprehensive pipeline and pile foundation be under construction smoothly simultaneously, effectively shorten engineering construction period, avoided comprehensive pipeline and pile foundation construction in stages, avoid ground to be excavated repeatedly, simplified engineering construction process to avoided excavating repeatedly to the impaired risk of the structure of having under construction thing, greatly reduced construction cost, and effectively reduced because the influence of excavating repeatedly to environmental quality.

Detailed Description
The following detailed description of the embodiments of the present invention will be made 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 middle part of the steel casing 2 is positioned in the upper soft stratum 11, the lower part of the steel casing 2 is positioned in the lower hard stratum 12, and a pile foundation 21 is poured in the steel casing 2; the upper soft stratum 11 is internally provided with a comprehensive pipeline 3.
The comprehensive pipelines 3 are positioned on two sides of the steel casing 2; a plurality of the steel casing 2 are arranged at intervals.
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.
In step 2, the pile foundation 21 is drilled while the impact drill with large vibration is forbidden, and the rotary drilling drill with small vibration or manual drilling is selected.
The utility model discloses a steel sheet pile 4 and steel protect a section of thick bamboo 2 and keep apart, use to the less digging soon of stratum disturbance bore or the artifical hole construction method construction pile foundation 21 drilling reduces the influence to synthesizing the pipeline construction, and pile foundation 21 drilling adopts the mud of special configuration to guarantee that pile foundation drilling does not collapse the hole simultaneously, guarantees that the stratum is stable to ensure to synthesize pipeline 3 and construct smoothly.
Other parts not described belong to the prior art.
