Further, with continued reference to Fig. 6, the construction method of supporting construction 100 is further comprising the steps of:
S240: along vertical or short transverse construction attachment beam approximately perpendicular to the first support pile, and connect attachment beam
First support pile and the second support pile；
S250: earth excavation forms foundation pit, and supporting element is arranged in foundation pit, abuts supporting element with attachment beam.
Specifically, the earthwork can stage excavation, one layer of one of supporting element 150 of then constructing of every digging, repetitive operation, until be excavated to
210 bottom of foundation pit.
Further, after the completion of supporting construction 100 is constructed, can construct basis in foundation pit 210.Foundation construction is completed
Afterwards, backfilling of earthwork is carried out.The first support pile 111 and the second support pile 112 are finally extracted using vibratory drilling method, so that the first supporting
Stake 111 and the second support pile 112 can be carried out recycling.
Above-mentioned supporting construction 100 is respectively provided with the first connector on the first support pile 111 and the second support pile 112
120 or second connector 130, and make with the second connector 130 mutually to connect and fix the first adjacent connector 120, thus
So that the first support pile 111 and the second support pile 112 are interconnected to form the supporting construction 100 of energy earth-retaining sealing, compared to table
The steel plate of face poor rigidity can be incited somebody to action by the supporting construction 100 that the first support pile 111 and the second support pile 112 connect and fix composition
On pressure dissipation to the first support pile 111 and the second support pile 112, and the first support pile 111 has with the second support pile 112
Higher rigidity and flexing resistance, so that supporting construction 100 has better shearing resistance, anti-pressure ability, and then avoiding need to be
Multiple tracks inner support or multiple anchor cable structures are constructed in supporting construction 100 to increase strength problem, reduce difficulty of construction and cost.
In addition, be easily installed and dismantle by the supporting construction 100 that the first connector 120 is connected together with the second connector 130, from
And it can reach and recycle, energy-saving and environment-friendly purpose.Simultaneously by two the first support piles 111 of first interval setting, then two
The second support pile 112 is squeezed between a first support pile 111.So as to produce between the first support pile 111 and the second support pile 112
Raw squeezing action, so that the connection of the first connector 120 and the second connector 130 more closely further improves, supporting knot
The intensity of structure 100.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
