Abstract
The invention discloses an underground continuous wall of an assembled lattice section steel TRD construction method and a construction method thereof.A lattice assembly is arranged in the wall of the TRD construction method to form the underground continuous wall of the assembled lattice section steel TRD construction method, and cement soil in the underground continuous wall is changed into a three-dimensional compression state from a one-way stretch bending stress state which is arranged on the outer side of section steel in the traditional construction method, so that the characteristic that the compression strength of the cement soil is far greater than the tensile strength and the shearing strength is fully exerted, and the horizontal support rigidity of the wall of the TRD construction method can be greatly improved; the technical problem that the lattice steel is difficult to integrally insert into the cement soil is solved by a successive insertion assembly mode, and the horizontal support rigidity of the wall in the TRD construction method can be effectively regulated and controlled by arranging the lattice area change and the combination of the lattice area change and the independent steel reinforcement body on the wall in the square lattice and the TRD construction method.
Description
Technical field
The invention belongs to geotechnical engineering pattern foundation pit supporting structure fields, and in particular to a kind of assembly lattice configuration steel TRD engineering method underground connects
Continuous wall and its construction method.
Background technique
Traditional diaphram wall is constructed using framing, is the weak link of sealing at Construction Joint, working procedure mostly with week
Phase is long, if cannot be combined into one with underground structure side wall, cost is excessively high, this also constrains what it was applied in general base pit engineering
Restriction condition.
TRD engineering method changes conventional soil cement stirring wall as equal thickness cement mixing wall Choice of Construction Technique of Water Stop Curtain
Single solum horizontal stirring mode, but the vertical stirring mode of different soil is realized by cutting box, have construction depth is big (can
Up to 60m), adapt to stratum is wide, mixing effect is good, seamless connection high at wall precision, suitable for height-limited operating environment.
The lateral rigidity of traditional SMW engineering method stake is mainly undertaken by the fashioned iron being inserted into, and cement mixing method is as flexible pile
Or Half rigid pile almost illegal its lateral rigidity of consideration contribution, the horizontal distortion of traditional SMW engineering method stake is larger, this is also to restrict
The bottleneck that this engineering method is applied in deep big foundation pit engineering.For SMW engineering method stake, if the rigidity for only relying on raising profile is come
The lateral rigidity for improving entire compound pile body, then will be sharply increased, pile body section also will be enlarged by, this certainly will make its warp with steel cost
Ji property is reduced to be increased with difficulty of construction.It mainly should be from taking effective way so to improve the working performance core of diaphram wall
Improve or play the lateral rigidity of Soil-cement Wall.
Cup type steel drum Rigid cable is by being enclosed in cup type steel drum for the stake core cement-soil of cement mixing method
Inside given full play to cement so that the soil cement inside steel drum becomes three dimension stress state from unidirectional stretch bending stress
Native compression strength is much larger than tension, the characteristic of shearing strength, to greatly improve the horizontal support rigidity of cement mixing wall.But
Cup type steel drum, since soil encircles effect of contraction as insertion depth is deepened, is inserted into extremely difficult when being inserted into cement mixing method；And
And due to the pile diameter domination of cement mixing method, so that steel drum diameter can not flexibly change, thus the support rigidity of such pile-type
It can not accomplish flexible modulation.
