Abstract
A kind of the foundation pit enclosure pilework and construction method of steel reinforced concrete drilling boundling stake, including crown beam, stake holes is interior to be inserted into fashioned iron, and connecting plate is used between fashioned iron, is bolted, stake holes concrete perfusion pile, fashioned iron upper end anchors into cast-in-situ steel reinforced concrete crown beam.Under the condition of narrow space, smaller diameter steel concrete drilling piling method is intensively arranged within the scope of certain diameter by small-sized forming machinery, forms boundling stake effect.The stake holes of 100~300mm of aperture is drilled within the scope of certain diameter, and by being inserted into fashioned iron, and concrete perfusion pile in hole.Pile crown is abolished after reaching concrete design strength, using pouring reinforcement concrete crown beam, so that smaller diameter steel concrete drilled pile pile crown is linked to be one in subrange and boundling stake effect is integrally formed, and adjacent boundling stake is made to connect into campshed, forms foundation pit enclosure structure.In the case where space limitation can not be using the stake of big machinery construction drill, has the characteristics that simple process, convenient, economic and reliable of constructing.
Description
Technical field
The invention belongs to base pit engineering technical fields, and in particular to a kind of foundation pit enclosure of steel reinforced concrete drilling boundling stake
Pilework and construction method.
Background technique
Drilled pile is a kind of common foundation pit enclosure structure, generally uses the figures such as percussive drill, rotary drilling rig in construction
Biggish machinery.But it in municipal administration, subway engineering construction, is influenced by ground buildings or structures, construction space often occurs
It is narrow, the case where biggish machinery of the figures such as percussive drill, rotary drilling rig can not construct.And artificial digging pile is used, it will cause
The disadvantages of construction cost increase, claim for eot, high security risk.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a kind of drilling boundling stakes of steel reinforced concrete
Foundation pit enclosure pilework and construction method, by using small-sized construction machinery construct smaller diameter steel concrete drilled pile boundling
Method, the construction of building enclosure drilled pile is realized in economic, efficient method.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of foundation pit enclosure pilework of steel reinforced concrete drilling boundling stake, including crown beam, are inserted into fashioned iron in stake holes, between fashioned iron
It using connecting plate, is bolted, stake holes concrete perfusion pile, fixed steel bars concrete crown beam on fashioned iron.
The stake holes is down-the-hole stake, and diameter is between 100~300mm.
Between the fashioned iron and stake holes should there are be not less than 100cm space.
The fashioned iron top should anchor into crown beam not less than 50cm, and fashioned iron bottom should be not less than 20cm with stake bottom distance.
The bending resistance attractive cross-sectional of the fashioned iron is consistent with foundation pit soil lateral pressure direction.
Further, a kind of construction method of the foundation pit enclosure pilework of steel reinforced concrete drilling boundling stake, which is characterized in that
The following steps are included:
1) surveying and locating makes stake position and hole depth；
2) stake holes is drilled out according to the stake position set and hole depth using hidden hole drilling；
3) according to fashioned iron bending resistance attractive cross-sectional and the consistent principle in foundation pit soil lateral pressure direction in hole, merogenesis is inserted into fashioned iron；
It is attached between fashioned iron using connecting plate, connection bolt；
4) downcomer in the stake holes of insertion fashioned iron, is perfused pile concrete；
5) after pile concrete reaches intensity, stake top concrete is abolished, exposes fashioned iron length 50cm；
6) crown beam reinforcing bar, template are installed, and pour crown beam concrete；
7) after crown beam concrete reaches intensity, make steel reinforced concrete drilled pile " local boundling, entirety are in a row ", form foundation pit enclosure
Pilework.
The beneficial effects of the present invention are:
The present invention has the advantages of simple process, construction convenient, economic and reliable.There is no the case where construction space in big machinery
Under, the method for smaller diameter steel concrete drilled pile of intensively constructing in subrange by using small-sized construction machinery passes through
The constraint of pile crown crown beam forms local boundling, whole rows of foundation pit enclosure structure, solves in the case where limited space,
The construction of building enclosure drilled pile is realized in economic, efficient method.
Detailed description of the invention
Fig. 1 is structure of the invention elevational schematic view
Fig. 2 is structure of the invention floor map
Fig. 3 is section steel connecting node schematic diagram of the present invention
1 it is wherein crown beam, 2 be stake holes, 3 be fashioned iron, 4 be pile concrete, 5 be connecting plate, 6 is bolt.
Specific embodiment
The present invention is further discussed below below in conjunction with attached drawing.
As shown in Figure 1, 2, 3, a kind of foundation pit enclosure pilework of steel reinforced concrete drilling boundling stake, including crown beam 1, stake holes
It is inserted into fashioned iron 3 in 2, is connected between fashioned iron 3 using connecting plate 5, bolt 6,2 concrete perfusion of stake holes, 4 pile, 3 upper end anchor of fashioned iron
Enter cast-in-situ steel reinforced concrete crown beam 1.Using the small-sized boring machine such as such as down-the-hole stake, aperture 100 is drilled within the scope of certain diameter
The minor diameter stake holes 2 of~300mm, and by being inserted into fashioned iron 3 in stake holes 2, and 4 pile of pile concrete is perfused.It is mixed reaching
Pile crown is abolished after solidifying soil design strength, using the method for pouring reinforcement concrete crown beam 1, minor diameter is not only made in subrange
Steel reinforced concrete drilled pile pile crown is linked to be one and boundling stake effect is integrally formed, and adjacent boundling stake is made to connect into campshed, shape
At foundation pit enclosure structure.
Stake holes 2 uses the small-sized forming machinery pore-forming of such as down-the-hole stake, and general diameter is between 100~300mm.
The model of fashioned iron 3 according to pore-forming flexible in size select, between fashioned iron 3 and stake holes 2 should there are be not less than 100cm sky
Between, in order to pour pile concrete 4；3 top of fashioned iron should anchor into crown beam 1 not less than 50cm, and 3 bottom of fashioned iron should be with stake bottom distance
Not less than 20cm.The bending resistance attractive cross-sectional of fashioned iron 3 is consistent with foundation pit soil lateral pressure direction.
A kind of construction method of the foundation pit enclosure pilework of above-mentioned steel reinforced concrete drilling boundling stake, comprising the following steps:
