Description
Technical field
The utility model is related to foundation pit enclosure technical fields, especially a kind of to be used for muddy soft soil, sand etc. distinguishingly
Layer supports supporting construction before increasing support end and the bellows of soil body contact area.
Background technology
With the continuous development of urban construction and Transport Facility Construction, more and more projects need pattern foundation pit supporting structure to ensure
The safety of hypogee construction, and the depth of excavation of foundation pit is also increasingly deeper, surrounding enviroment also become increasingly complex, in order to for building
The peak use rate on ground, the place usable floor area for leaving pattern foundation pit supporting structure for is also fewer and fewer, also higher and higher to the safety of foundation pit.
Currently, the support forms such as slope, soil cement gravity dam or double-row pile that foundation pit uses, the area of occupancy is larger, and
Foundation pit relatively depth and the smaller foundation pit of the place usable floor area for leaving pattern foundation pit supporting structure for, are generally used the branch of board-like supporting+inner support
Protection structure, inner support is generally using the horizontally-supported or oblique form for throwing support, but horizontally-supported cost is higher, and difficulty of being unearthed tiltedly is thrown
Support influences construction of bottom plates.
The supporting construction of the prior art is difficult to construct in special formations such as muddy soft soil, sands, and position is supportted before be easy to causeing
It moves, stability is poor.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art and to support supporting construction before a kind of bellows of design, is used
Bellows expand the preceding support of body structure, to increase the contact area of support end and the soil body, support displacement before can effectively limiting, ensure supporting knot
The stability of structure, supporting effect is good, can fully save the underground space, increase economic efficiency, and is particularly suitable for surrounding enviroment complexity,
Existing building is more, the excavating sideline foundation pit supporting project construction closer apart from red line.
What the purpose of this utility model was realized in：Support supporting construction before a kind of bellows, including support system and by
" H " shaped steel is inserted into the advanced support in rotary churning pile, and advanced support in the oblique foundation pit of 30~45° angle degree to be arranged, and " H " shaped steel one
The Guan Liang held and be arranged at the top of support system connects, and the other end is inserted into the rotary churning pile being arranged under bottom plate, its main feature is that " H " type
Steel one end is equipped with the fixed utricule of seal assembly, and utricule is inserted into rotary churning pile together with " H " shaped steel, and cement is formed on rotary churning pile
It is supportted before the bellows of packet, the seal assembly setting is being fixedly connected for sealing at utricule both ends and with " H " shaped steel.
The bottom plate is connect equipped with load transfering strip with support system.
The bottom plate or exterior wall intersection of " H " shaped steel and basement are equipped with sealing steel disc.
The utility model has the contact area for increasing support end and the soil body compared with prior art, effectively supports position before limitation
It moves, ensures the stability of supporting construction, supporting effect is good, can fully save the underground space, increase economic efficiency, be particularly suitable for
Surrounding enviroment are complicated, and existing building is more, the excavating sideline foundation pit supporting project construction closer apart from red line.

Specific implementation mode
Refering to attached drawing 1, the present invention includes support system 1 and is inserted into the advanced branch formed in rotary churning pile 2 by " H " shaped steel 3
Support, advanced support in the oblique foundation pit of 30~45° angle degree to be arranged, and described 3 one end of " H " shaped steel is with setting at 1 top of support system
Guan Liang 4 connect, the other end is inserted into the rotary churning pile 2 that is arranged under bottom plate 6；Described 3 one end of " H " shaped steel is solid equipped with seal assembly 10
Fixed utricule 8 after utricule 8 is inserted into the projected depth of rotary churning pile 2 together with " H " shaped steel 3, and fills cement mortar in utricule 8, makes
It is supportted before obtaining the bellows for forming cement packet 11 on rotary churning pile 2；The seal assembly 10 is arranged at 8 both ends of utricule and with " H " shaped steel 3
Sealing is fixedly connected；The bottom plate 6 is connect equipped with load transfering strip 7 with slab supporting system 1；The bottom of " H " shaped steel 3 and basement
Plate 6 or 16 intersection of exterior wall are equipped with sealing steel disc 5.
Refering to 2~Fig. 3 of attached drawing, board-like support system 1 and slot grooving Guan Liang 4 are set along excavation of foundation pit sideline, with
And hole bottom is constructed with the rotary churning pile 2 of lower portion, then carries out the construction of the bottom plate 6 and exterior wall 16 and load transfering strip 7 of basement,
In " H " shaped steel 3 and bottom plate 6 and 16 intersection of exterior wall setting sealing steel disc 5；The rotary churning pile 2 uses all hydraulic caterpillar drilling machine
Construction, diameter are 800mm, and angle of inclination is 30~45 °.
Refering to 4~Fig. 5 of attached drawing, preceding support main body is by " H profile steel 3 and utricule 8 form, and the utricule 8 uses canvas material system
