With the continuous propulsion of Process of Urbanization Construction process, the development and utilization of the underground space is become more and more important.Wherein,
The development of base pit engineering is especially rapid, just develops towards big depth, large area direction.Base pit engineering is comprehensive strong, technical difficulty
Height is all a problem of engineering circles all the time.The excavation of foundation pit needs to guarantee foundation pit deformation within control range, true
Protect the influence being substantially reduced while foundation pit safety itself to ambient enviroment.Common foundation pit enclosure form has cement mixing
Stake, diaphram wall, Larsen steel sheet pile etc..Wherein, cement mixing pile construction effect is unstable, and waterproof effect is bad；Underground connects
The waterproof effect of continuous wall is fine, but cost is too high；Larsen steel sheet pile then shows Lack of support, easily topples, easy to leak etc.
Disadvantage.And as the interlocking pile of pattern foundation pit supporting structure new situations have construction efficiency high, barrier performance and supporting performance preferably, pile matter
The advantages that amount is high, low cost easily controllable to sedimentation and deformation and construction are safer has obtained quick development in recent years and has answered
With.
And in the application of Practical Project, it is unknown whether interlocking pile bottom is engaged, when stake bottom is not fully engaged against,
The effect of its sealing and earth-retaining, is just unable to give full play, and the soil body and water outside hole can enter foundation pit by non-occlusive section of gap
Inside influences normal foundation pit construction, in some instances it may even be possible to cause water burst to gush the safety accident of mud, the collapsing of foundation pit is caused to fail.
In conclusion the construction of interlocking pile lacks one kind at present cheer and bright can judge the side whether stake bottom is engaged
Method needs a kind of novel occlusion pile constructing process to judgement Shortcomings whether occlusion of interlocking pile bottom, can be faster
Victory more clearly judges whether stake is fully engaged against, if needs are modified.
Summary of the invention
The purpose of the present invention is overcoming deficiency in the prior art, provide whether a kind of novel judgement interlocking pile be engaged is applied
Work method.
The construction method whether this novel judgement interlocking pile is engaged, comprising the following steps:
1) preparation before first carrying out construction removes ground sundries, fills and leads up groove；
2) surveying setting-out calculates campshed center line coordinates according to design drawing, carries out setting-out on the spot using total station；
3) concrete guide wall is constructed: including channel excavation, reinforcing bar binding, template construction and concrete pouring construction；Groove
Using hand excavation, center line is introduced into groove, it is ensured that it is correct to lead center line of wall；After the completion of channel excavation, binding and arrangement
Reinforcing bar；Concrete pouring construction is carried out after last template passed examination；
4) stake machine is in place, wait lead wall intensity it is sufficiently high when, form removal, relocate setting-out campshed center；Stake machine
Grab bucket takes soil after in place, pushes casing, so circulation is gone down, until reaching bottom hole design hole depth；
5) it hangs steel reinforcement cage: after drilled-hole inspecting is qualified, carrying out steel reinforcement cage and place work, need to carry out steel reinforcement cage before hanging
It checks whether work, such as diameter, size, solder joint deform, finally guarantees to reach correct design hole depth；It is mixed that construction location is located at element
Between solidifying B1 and plain concrete B2, soil, it is mutually twisted with plain concrete B1 and plain concrete B2；Steel reinforcement cage and element are mixed
The B2 and plain concrete B3 occlusions of solidifying soil, so recycle；
6) blue concrete perfusion: is presented to stake bottom by pouring into casing with the concrete that blue pigment is stirred in advance
Then concrete will constantly be poured in casing using conduit without pigment concrete continuous, form plain concrete B1；
Other adjacent plain concrete pile constructions are same as above, and only two adjacent plain concrete pile lower concrete colors are different, two kinds of face
Color is spaced, and if B2 bottoms of plain concrete pile are red concrete, B3 bottoms of plain concrete are blue concrete, and element is mixed
Solidifying B4 bottoms of soil are red concrete, and so on go down；Before B2 plain concrete B1, plain concrete initial sets, in element
Casting concrete forms armored concrete A1 between concrete B1 and plain concrete B2, and judges whether to be engaged；Similarly
It pours to form armored concrete A2 between plain concrete B2 and plain concrete B3, and judges whether to be engaged, it is mixed in element
