Abstract
The present invention relates to the pattern foundation pit supporting structure processing methods in the narrow space of the library one kind Fang Yudi, the steps include: 1) construction room pile foundation；2) small seam allowance steel sheet pile is set in ground library and a number room boundary position；3) number of pouring room bed course, distance room and garage difference of height juncture area 5m inner cushion layer configuration reinforcement mesh sheet；4) Two bors d's oeuveres channel steel purlin is arranged in steel sheet pile side, pull rod is passed through reserved opening in the middle part of steel sheet pile and purlin, end setting anchor head is fixed, and the other end is connected and fixed with the reinforcing steel bar of pull rod connector being arranged in bed course；5) construction room bottom plate；6) the low garage foundation pit of colon room bottom plate is excavated, bottom plate and external wall structure construction are carried out；After the completion of garage basement construction, steel sheet pile recycling is pulled out.Using difference of height foundation pit that can well between the number of processing room bottom plate and ground library in narrow space of the invention, pile foundation is intensive and lead to the problem of support system construction space deficiency under the number of avoiding room bottom plate, also avoids displacement, the destruction of number room bottom plate and pile foundation caused by ground library is excavated.
Description
Technical field
The present invention relates to the pattern foundation pit supporting structure in the narrow space of the library one kind Fang Yudi, the especially library one kind Fang Yudi is narrow
Pattern foundation pit supporting structure processing method in space.
Background technique
Currently, in building engineering, developed and required due to basement, generally requires to carry out pattern foundation pit supporting structure, but root
According to architectural composition, number room basement bottom board generally greater than library basement bottom board, under not supporting state library excavation often
The displacement of the number of will lead to room pile foundation and bottom plate, damages.Under normal circumstances, it will do it in ground library and a number room height boundary position
Supporting, the often self-supporting support system such as Soil-cement Wall gravity dam of use, but in most cases under number premises
Distance is narrow between room bottom plate and ground library exterior wall, and the Influence of Pile Foundation in number room, can not supporting to the construction of self-supporting support system.
Summary of the invention
The present invention is to provide for the pattern foundation pit supporting structure processing method in the narrow space of the library one kind Fang Yudi, in narrow space
Depth intersection foundation pit carries out supporting, and this method can avoid the insufficient disadvantage of traditional handicraft construction space, and the solution duration is limited, work
The shortcomings that journey cost secondary waste.
To achieve the above object, the technical scheme is that pattern foundation pit supporting structure in the narrow space of the library one kind Fang Yudi
Processing method, which is characterized in that comprise the concrete steps that:
1) construction room pile foundation, pile foundation set small seam allowance steel sheet pile in ground library and a number room boundary position after the completion；
2) number of pouring room bed course, distance room and garage difference of height juncture area 5m inner cushion layer configuration reinforcement mesh sheet, and set
Set horizontal direction rod head；
3) Two bors d's oeuveres channel steel purlin is arranged in steel sheet pile side, and pull rod is passed through reserved opening in the middle part of steel sheet pile and purlin, end
Setting anchor head is fixed, and the other end is connected and fixed with the reinforcing steel bar of pull rod connector being arranged in bed course；
4) construction room bottom plate；
5) the low garage foundation pit of colon room bottom plate is excavated, bottom plate and external wall structure construction are carried out；To garage basement construction
After the completion, steel sheet pile recycling is pulled out.
Further, the library described Fang Yudi difference of height position carries out supporting using the steel sheet pile to occupy little space.
Further, the steel sheet pile is connect using steel bar rod with a number room bed course.
The beneficial effects of the present invention are:
Using the present invention, difference of height foundation pit that can well between the number of processing room bottom plate and ground library in narrow space is avoided
Pile foundation is intensive and lead to the problem of support system construction space deficiency under number room bottom plate, also avoids ground library and excavates caused number
The displacement of room bottom plate and pile foundation destroys.In addition, steel sheet pile due to that can lease, without maintenance, substantially reduces the work of engineering
Phase, it can carry out pulling out recycling after engineering, it is also greatly considerable in economy, in technical feasibility, working efficiency, implementation
Traditional approach is all much stronger than in effect.
Detailed description of the invention
Fig. 1 is the pattern foundation pit supporting structure processing schematic in number library Fang Yudi narrow space of the invention.
Specific embodiment
Below with reference to specific example, the embodiment that the present invention is further explained.It should be understood that these examples are merely to illustrate
The range of the present invention rather than limitation the invention patent.In addition, it should also be understood that, after reading the content taught by the present invention, this
Field technical staff can make various changes or modifications the present invention, and such equivalent forms equally fall within right appended by the application and want
Seek book limited range.
As shown in Figure 1, the pattern foundation pit supporting structure processing method in the narrow space of the library one kind Fang Yudi, comprises the concrete steps that:
1) construction room pile foundation 1, pile foundation set small seam allowance steel sheet pile 7 in ground library and a number room boundary position after the completion；
2) number of pouring room bed course 2, distance room and garage difference of height juncture area 5m inner cushion layer configuration reinforcement mesh sheet 3, steel
Muscle specification is Φ 10@150 (bar diameter 10mm, spacing 150mm) single-layer bidirectional, while 20@of horizontal direction pull rod Φ is arranged
1000 (5 diameter of pull rod is 10mm, spacing 1000mm) connectors；
3) Two bors d's oeuveres channel steel purlin 8 is arranged in 7 side of steel sheet pile, and pull rod is passed through reserved opening in the middle part of steel sheet pile and purlin, is enclosed
Purlin end is arranged anchor head 6 and fixes, and the reinforcing steel bar of pull rod connector being arranged in the other end and bed course 2 is connected and fixed to form anchor-pull brace body
The earthwork of system, check mark room pile foundation and difference of height region carries out supporting and retaining system protection；
4) after the completion of a number room bottom plate 4 pours, the low garage foundation pit of colon room bottom plate is excavated, bottom plate and external wall structure are carried out
Construction；After the completion of garage basement construction, steel sheet pile recycling is pulled out.
