Detailed description of the invention
Below in conjunction with specific embodiment and Figure of description, this utility model is described in detail.
As depicted in figs. 1 and 2, the dual-purpose underground gallery structure that this utility model provides, including
Foundation ditch 3 between the pile foundation 1 that two rows are oppositely arranged, the cap being arranged in pile foundation 1, two campshed bases 1
With the underground gallery being arranged in foundation ditch 3, between the two adjacent pile foundations 1 often arranged be spaced apart 100～
200mm, underground gallery is poured by reinforced concrete box culvert 4 and forms.Its construction method includes following step
Rapid:
Based process: cleaning old road base, and construction site is done cast-in-situ bored pile process, pile foundation 1 is close
Arrangement is set to two rows being oppositely arranged, and the adjacent pile foundation 1 often arranged is spaced 100～200mm, pile foundation 1
Length according to when gallery vertical bearing capacity and excavation of foundation pit retaining wall horizontal bearing capacity require maximum true
Fixed；
Foundation ditch 3 excavates: pour cap 2 at the top of each pile foundation 1, each pile foundation 1 is unified, digs
Foundation ditch 3, section construction；
Gallery pours: dispose reinforced concrete box culvert 4, segmentation to pour formation ground between two campshed bases 1
Lower gallery, arranges measures of preventing water between each section of underground gallery；
Pavement construction: after underground gallery has poured, forms new road surface 5 to top pavement construction.
Preferably, pile foundation 1 uses the reinforcing bar of Φ 600mm～Φ 1000mm to form with concreting,
May be used without other prefabricated pile foundation.
Preferably, after foundation ditch 3 has excavated, bottom foundation ditch 3, lay slabstone fill sand compacting layer 31,
Then C15 concrete cushion 32 is re-layed.The bottom of foundation ditch 3 is provided with slabstone from top to bottom and fills sand compacting
Layer 31 and C15 concrete cushion 32.
Preferably, as it is shown on figure 3, every campshed base 1 uses stirrup 11 of putting more energy into fix.
Preferably, as shown in Figure 4, pile foundation 1 is in bottom foundation ditch 3 following part and is provided with 6 pieces the
One reinforcing bar 12, is in part above bottom foundation ditch 3 and is provided with 12 second reinforcing bars 13.Due to foundation ditch 3
Can bear bigger horizontal bearing capacity with the adjacent of reinforced concrete box culvert 4, therefore reinforcing bar number is more
Many, beneficially the stablizing of pile foundation 1.
Preferably, between cap 2, horizontal temporary support is arranged.
Preferably, backacter or hydraulicking foundation ditch 3 are used.
Preferably, underground gallery is divided into multistage, arranges measures of preventing water between adjacent two sections.
Comparing with traditional soft base gallery structure, this utility model has the advantage that
1) structural safety: use the reinforced concrete bored pile of solid matter to carry out pattern foundation pit supporting structure process,
Pile foundation is resistant to by bigger horizontal force, and foundation pit deformation is little, i.e. ensure that the construction safety of excavation of foundation pit,
Also the construction period impact on Nearby Structure is reduced；
2) construction is quickly: the pile foundation of gallery based process and the lagging pile base junction of gallery excavation of foundation pit are closed
Get up, decrease the based process construction workload of underground gallery after excavation of foundation pit, accelerate construct into
Degree；
3) excavation scope is little: owing to being complete pile foundation construction before excavation of foundation pit, excavation of foundation pit no longer needs
Constructing in slope to be put, can reduce the opening range of excavation face, simultaneously directly along interior pile lining vertical cut
Decrease the traffic conflict of road；
4) construction costs is low: owing to the pile foundation of gallery based process and the pile foundation of foundation ditch retaining wall combine,
Permanent based process pile foundation and interim supporting are processed the two-in-one process of pile foundation, reaches a dual-purpose
Purpose, reduce pile foundation engineering amount, reduce construction investment, compare according to the same condition of built engineering and set
Meter, reduces architectural engineering investment about 15～20%.
This utility model, by underground gallery based process pile foundation and the lagging pile base junction of gallery excavation of foundation pit
Altogether, pile foundation when excavation of foundation pit as foundation pit supporting pile, to undertake horizontal bearing capacity, ground
As the basic pile foundation of superstructure after the construction of lower gallery, to undertake vertical bearing capacity, reach one
Stake dual-purpose purpose, has raising structural safety, reduces pavement excavation scope, strengthens that foundation ditch is stable, adds
The fast feature such as construction speed, cost saving, ground, the city being readily applicable under existing soft base road
Lower gallery construction, has good promotional value and application prospect.
This utility model is not limited to above-mentioned preferred forms, and anyone should learn in this practicality new
The structure change made under the enlightenment of type, every have same or like technical side with this utility model
Case, within each falling within protection domain of the present utility model.
