Abstract
The utility model relates to a joint structure between two different fender bodies in a deep foundation pit, which comprises a bored pile soil-blocking structure, a Larson steel plate pile soil-blocking structure and a soil-cement mixing pile water-stopping structure. The joint structure is characterized in that: the Larson steel plate pile soil-blocking structure is extended outwards to form an extended water-stopping segment at the vertical intersecting position between the bored pile soil-blocking structure and the Larson steel plate pile soil-blocking structure, and the soil-cement mixing pile water-stopping structure envelopes the bored pile soil-blocking structure, the Larson steel plate pile soil-blocking structure and the extended water-stopping segment from the periphery so as to form the labyrinth type joint structure. The joint structure has the advantages of effective soil blocking, long lasting time of water stopping, stable combination, strong seepage resisting performance, simple as well as convenient construction and the like.
Description
Technical field
The utility model relates in the deep foundation ditch of a kind of industry and civilian construction the joint design between two kinds of different fender bodies.
Background technology
In the construction of deep big foundation pit, run into a underground structrue engineering by two owners or divide the situation (as Fig. 1) that two phases successively developed through regular meeting.For guaranteeing the reliability of (or first owner) foundation pit construction in early stage, should foundation ditch around ring close, it is continuous with early stage (or first owner) to take into account later stage (or second owner) foundation pit enclosure structure again.(or the first owner) foundation pit enclosure structure in early stage that for this reason requires to be located at the later stage in (or second owner) zone must be able to be removed smoothly, and must keep off soil effectively in early stage in the bracing of foundation pit.Therefore in the global design of foundation ditch, formed the combination of two kinds of different fender body structures, effective for the application that makes these two kinds of different fender body textural associations, must guarantee that its joint between the two is effective.Cause heavy economic losses for fear of having an accident, the joint design between different dimensional protection structure body has been proposed requirements at the higher level.
The utility model content
Joint design between two kinds of different fender bodies is provided to provide in a kind of deep foundation ditch the purpose of this utility model, stability and the anti-leakage that it has effective retaining soil and the sealing efficiency time is long, strengthen the junction, the advantage such as simple of constructing.
For achieving the above object, the present invention adopts following technical proposals:
Joint design in a kind of deep foundation ditch between two kinds of different fender bodies, comprise drill-pouring pile soil-baffling structure, Larsen steel sheet pile soil-baffling structure and cement mixing method water-stopping structure, it is characterized in that in described drill-pouring pile soil-baffling structure and the vertical intersection of Larsen steel sheet pile soil-baffling structure, the Larsen steel sheet pile soil-baffling structure one section extension sealing section that stretches out, described cement mixing method water-stopping structure described drill-pouring pile soil-baffling structure and Larsen steel sheet pile soil-baffling structure and extension sealing section thereof from peripheral envelope, constitutes the labyrinth joint structure.
Above-mentioned drill-pouring pile soil-baffling structure is perpendicular retaining fortifield village watch box of listing in the foundation ditch perisporium, and described Larsen steel sheet pile soil-baffling structure is listed in the interim retaining fortifield village watch box that deep foundation ditch is cut apart the place for perpendicular.
Between the Larsen steel sheet pile soil-baffling structure of above-mentioned extension sealing section and the cement mixing method water-stopping structure compaction grouting is arranged, this compaction grouting is the cement compaction grouting.
The perimetric length L of above-mentioned extension sealing section is 2.5～3 meters.。
The utility model compared with prior art, have following conspicuous substantive distinguishing features and advantage: the utility model forms the labyrinth joint structure by the lap length of control space enclosing structure, the underground water horizontal permeation path of effectively having extended delays and reduces and even the seepage stopped herein takes place.By to the compaction grouting between water-stopping structure and soil-baffling structure, remedied as the cement mixing method of water-stopping structure and the interlock defect of insufficient has easily taken place on the technology between stake and then making antiseepage tighter, soil body permeability resistance is strengthened, have more characteristics such as the sealing efficiency time is long, construction is simple.
Description of drawings
Fig. 1 is the underground construction subregion schematic diagram of the deep foundation ditch of one of the utility model with two kinds of different fender bodies.
Fig. 2 is the joint design at A place among Fig. 1.
Fig. 3 is a B-B place sectional drawing among Fig. 2.
The specific embodiment
A preferential embodiment accompanying drawings of the present utility model is as follows: referring to Fig. 1, Fig. 2 and Fig. 3.Joint design in this deep foundation ditch between two kinds of different fender bodies, comprise drill-pouring pile soil-baffling structure 3, Larsen steel sheet pile soil-baffling structure 6 and cement mixing method water-stopping structure 2, described drill-pouring pile soil-baffling structure 3 and Larsen steel sheet pile soil-baffling structure 6 vertical intersections, the Larsen steel sheet pile soil-baffling structure 6 one section extension sealing section 4 that stretches out, described cement mixing method water-stopping structure 2 described drill-pouring pile soil-baffling structure 3 and Larsen steel sheet pile soil-baffling structure 6 and extension sealing section 4 thereof from peripheral envelope, constitutes the labyrinth joint structure.
Above-mentioned drill-pouring pile soil-baffling structure 3 is perpendicular retaining fortifield village watch box of listing in foundation ditch perisporium 1.
Above-mentioned Larsen steel sheet pile soil-baffling structure 6 is listed in the interim retaining fortifield village watch box that deep foundation ditch is cut apart place 7 for perpendicular.
Between the Larsen steel sheet pile soil-baffling structure 6 of above-mentioned extension sealing section 4 and the cement mixing method water-stopping structure 2 compaction grouting 5 is arranged, this compaction grouting 5 is the cement compaction grouting.
The perimetric length L of above-mentioned extension sealing section 4 is 2.5～3 meters.
