Abstract
The utility model relates to a concealed tunneling structure with a pile foundation, which comprises an upper arch wall structure and a lower bottom plate supporting structure, and is characterized in that the upper arch wall structure consists of a tunnel primary support and a tunnel arch wall secondary lining, the lower bottom plate supporting structure consists of the pile foundation and a tunnel bottom plate, the pile foundation is positioned below the tunnel bottom plate, the tunnel bottom plate is positioned on the bottom surface of the upper arch wall structure, and the upper arch wall structure and the lower bottom plate supporting structure are connected into a whole. The concealed tunneling structure is safe and reliable, can ensure long-term safe operations of tunnels and greatly save damage repairing cost in the operation period, and is applicable to a section of a concealed tunnel passing through a soft stratum, especially to a water-rich hollow section with extremely low bearing capacity.
Description
Technical field
The utility model relates to a kind of bored tunnel structure with pile foundation, belongs to tunnel and underground engineering field.
Background technology
When inevitably running into soft stratum, especially tunnel in the constructing tunnel and passing through the water-enriched filling solution cavity, the whether firm key factor that just becomes the tunnel operation security in basis.
Methods such as the more employing of bored tunnel based process is at present changed and filled out, leap, grouting and reinforcing.Wherein, change and fill out processing to grow degree of depth applicability for soft stratum relatively poor; Plate-girder is crossed over and is only applicable to handle the short soft stratum of distance; The grouting and reinforcing treatment effect is difficult to guarantee, easily causes settlement after construction, operation phase disease incidence height.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to provide a kind of structural integrity good, resist the bored tunnel structure of the strong band pile foundation of external load ability, with effective control tunnel subsidence, guaranteeing the long-term operation security in tunnel.
For achieving the above object, the utility model adopts following technical scheme: a kind of bored tunnel structure with pile foundation, comprise top arch wall structure and lower raft braced structures, it is characterized in that: described top arch wall structure is made of tunnel preliminary bracing and tunnel arch wall secondary lining; Described lower raft braced structures is made of pile foundation and tunnel floor, and pile foundation is positioned at below the tunnel floor, and tunnel floor is positioned at arch wall structure bottom surface, top; Described top arch wall structure and lower raft braced structures are connected to integral body by tunnel floor.
Preferably, described tunnel floor and tunnel arch wall secondary lining are rigidly connected.
Preferably, described pile foundation is a reinforced concrete bored pile.
This utility model has the following advantages with respect to prior art:
1) strong for basement weak stratum, the tunnel growth location applicability that scale is big, scope is wide, be particularly useful for extremely low, the empty section of Fu Shui, supporting capacity.
2) tunnel defects such as lining cutting cracking that can effectively avoid settlement after construction and bring out significantly reduce operation phase tunnel maintenance expense.
3) this structural integrity is strong, and arch wall secondary lining, tunnel floor, pile foundation are rigidly connected, and bears load jointly, and structural safety is reliable.
The utility model structural safety is reliable, can guarantee the long-term operation security in tunnel, significantly saves operation phase disease regulation expense, is applicable to that bored tunnel passes through the soft stratum location, is particularly useful for extremely low, the empty section of Fu Shui, supporting capacity.
Description of drawings
Fig. 1 the utility model cross-sectional configuration arrangement diagram.
The specific embodiment
Below by drawings and Examples, the utility model is described in further details, so that technician's of the same trade understanding.
As shown in Figure 1, present embodiment relates to a kind of bored tunnel structure with pile foundation, comprises top arch wall structure and lower raft braced structures, and described top arch wall structure is made of tunnel preliminary bracing 1 and tunnel arch wall secondary lining 2; Described lower raft braced structures is made of pile foundation 3 and tunnel floor 4.Described top arch wall structure and lower raft braced structures are connected to integral body by tunnel floor 4.
Described tunnel arch wall preliminary bracing 1 is positioned at the tunnel outermost layer, bears that the free face country rock discharges load behind the tunnel excavation.
Described tunnel arch wall secondary lining 2 and preliminary bracing 1 acting in conjunction are born the country rock long duration load, guarantee operation phase safety.
Described pile foundation 3 pile foundations are positioned at below the tunnel floor, are the tunnel bottom bearing structure, the lining cutting cracking of avoiding tunnel subsidence and bringing out, and pile foundation is generally reinforced concrete bored pile, and the stake end need enter the bearing stratum certain depth.
Described tunnel floor 4 is positioned at arch wall structure bottom surface, top; Be rigidly connected between tunnel floor 4, tunnel arch wall secondary lining 2 and the pile foundation 3, be used to transmit the superstructure load and run of the effect of phase load to bottom pile foundation 3.
The utility model structural integrity is good, opposing external load ability is strong, pass through for bored tunnel that soft stratum compliance is strong on a large scale, treatment effect is good, the generation of the tunnel defects such as lining cutting cracking that can effectively avoid the tunnel settlement after construction and bring out, guarantee the tunnel operation security, be specially adapted to bored tunnel and pass through the soft stratum location, as solution cavity, underground river, rich water weak surrounding rock location etc.
Claims (3)
1. the bored tunnel structure with pile foundation comprises top arch wall structure and lower raft braced structures, it is characterized in that: described top arch wall structure is made of tunnel preliminary bracing and tunnel arch wall secondary lining; Described lower raft braced structures is made of pile foundation and tunnel floor, and pile foundation is positioned at below the tunnel floor, and tunnel floor is positioned at arch wall structure bottom surface, top; Described top arch wall structure and lower raft braced structures are connected to integral body by tunnel floor.
