Background technology
China is in the eighties extensively using in building enclosure and water-stop curtain of the mixing pile in foundation pit supporting project.Although
Mixing pile construction is easy to operate, construction efficiency is high, and without friction in construction, noiseless is polluted without mud waste water, but mixing pile is most
It can only construct in soil, the constructional difficulties in competent bed, and the combination of cement and soil, due to there is no coarse aggregate to do wherein
It is primarily subjected to the material of load, force-mechanism is simultaneously bad, and strength of the mixing pile is not high.Shaped steel cement mixing method, interpolation shaped steel improve
Bearing capacity, the secondary recovery of shaped steel reduce cost, but since mixing pile is not easy to construct in competent bed, certain journey
The extensive use of SMW engineering methods is limited on degree.Diaphram wall rigidity is big, good integrity, and deformation is relatively small, has preferable anti-
Performance, but the grooving in rock stratum are oozed, it is difficult using common process grooving, it is less efficient, if selecting slotter, it can be met
In rock grooving work efficiency, but cost higher.
Therefore in order to solve problem above, in project of national nature science fund project (number:41372288) it under subsidy, opens
Great mass of data search, field research and related experiment have been opened up to be studied, invention is a kind of can both to construct in competent bed,
Pile body bearing capacity can be increased substantially again, accelerates speed of application, and the lower embedding lithotype steel cement mixing wall of cost.
Invention content
The purpose of this utility model is to provide a kind of embedding lithotype steel cement mixing wall, is made using the rock debris that rock drilling generates
For coarse-fine aggregate, interpolation shaped steel can construct in competent bed, increase substantially the bearing capacity of pile body；Traditional SMW engineering methods are not
It is well positioned to meet the building-in depth requirement of pattern foundation pit supporting structure needs, and the utility model can be applied to the relatively thin pattern foundation pit supporting structure of soil layer
In engineering, engineering adaptability is wider；Operation is simple for it, using meat and vegetables stake combination of long drives and drop shots, compared with diaphram wall, rock drilling
Amount substantially reduces, and can reach and not only improve work efficiency, shortened the construction period, but also the corresponding purpose for reducing project cost.
Technical solution adopted in the utility model is：A kind of embedding lithotype steel cement mixing wall, it is by Guan Liang, shaped steel, water
Soil mixing pile is formed with rock mixing pile is entered；The Guan Liang is located at earth's surface or more, is reinforced concrete structure；The shaped steel
It connects Guan Liang and enters rock mixing pile；The cement mixing method is engaged between rock mixing pile, the sealing as stirring wall
Structure；It is described that enter rock mixing pile be top is cement and the mixing pile that soil stirring, lower part are cement and rock debris stirring.
The construction usage method of the utility model is：A kind of embedding lithotype steel cement mixing wall, carries out in accordance with the following steps：
Step 1：It is constructed into rock mixing pile using special construction machinery, heavy bore of drilling machine stirs and pass through soil layer, into rock
The rock debris of layer drilling, generation stays in above working face, and after being drilled into designed elevation, drilling machine carries brill and whitewashes and stir, and makes water
Slurry liquid is sufficiently mixed with rock debris, is carried and is drilled into soil layer and is then thoroughly mixed cement grout and the soil body, ultimately forms one
Root top pile body is cement to be combined with soil, lower part pile body be cement combined with rock debris enter rock mixing pile；
Step 2：Using the cement mixing method for cement-soil mixing pile machine construction and entering rock mixing pile and being engaged, and rock will be entered and stirred
It mixes top pile body of the stake in soil layer and combines stirring with cement earth pile, become one；
Step 3：It is inserted into shaped steel in entering rock mixing pile, shaped steel is vibrated when being inserted into the lower part pile body into rock mixing pile, passes through
The vibration of shaped steel makes the rock debris in pile body and the closely knit combination of cement grout, and it is existing to eliminate bubble, voids and pits in pile body etc.
As；
Step 4：Pile body is connected into an entirety by construction Guan Liang, and Guan Liang is located at cement mixing wall top, and height 500mm is left
The right side, Guan Liang top surface should be in shaped steel top surface 500mm hereinafter, extracting shaped steel after terminating so as to pattern foundation pit supporting structure.
The operation principle of the utility model is：A kind of embedding lithotype steel cement mixing wall, when constructing into rock mixing pile, drilling machine chisel
The rock debris not of uniform size that rock generates is combined during proposing brill whitewashing stirring with cement grout, and rock debris is as thick
Fine aggregate, cement grout is as adhesive, and shaped steel is as main force structure, and while being inserted into shaped steel vibrates rock therein
Clast forms the pile body of high intensity；Due to having structure of the shaped steel cement mixing pile into rock as bearing load, Soil-cement
Stake is engaged therewith, and an entirety is stirred into construction, and the stirring wall of composition has not in resistance soil pressure, sealing etc.
Wrong effect；Using meat and vegetables stake combination of long drives and drop shots, compared with diaphram wall, rock drilling amount substantially reduces, and can reach and both improve work
Effect shortens the construction period, and the corresponding purpose for reducing project cost.
The utility model has the beneficial effects that：A kind of embedding lithotype steel cement mixing wall, the rock debris generated using rock drilling
As coarse-fine aggregate, interpolation shaped steel can construct in competent bed, increase substantially the bearing capacity of pile body；With traditional SMW works
Method is compared, and can be applied in the relatively thin foundation pit supporting project of soil layer, engineering adaptability is wider；Operation is simple for it, uses
Meat and vegetables stake combination of long drives and drop shots, compared with diaphram wall, rock drilling amount substantially reduces, and can reach and both improve work efficiency, shortened construction work
Phase, and the corresponding purpose for reducing project cost.
