Description
Technical field
The utility model relates to a kind of settlement Control structures for being applicable in cheuch section lid and holing.
Background technique
With the fast development of the western basic means of transportation in China, a large amount of Tunnel Engineering has been emerged in large numbers everywhere.The west in China
Portion, the mountain ridge, area in length and breadth, will will appear a large amount of Tunnel Passing mountain ridge cheuch section, this will unavoidably form cheuch section an ultra shallow
Tunnel is buried, and digging method construction can guarantee to reduce the shadow to ambient enviroment under the premise of super Shallow Section construction supporting safety
It rings, and traffic above-ground can be restored in a short time, cover and cut construction method surpasses in Shallow Section in tunnel has other construction methods not have
Superiority, now have begun it is expanded should in mountain area constructing tunnel, so the following mountain ridge super shallow-buried tunnel construction middle cover dig
Method construction can be more and more.But in general, for mountain ridge coombe throughout the year by the erosion of rainwater, geological environment is generally poor, tunnel
Situations such as Surrounding Rock Strength is low, stability is poor, rock mass loose crushing, also seeps water with a degree of earth's surface, frequent occurrence tunnel
It collapses or even natural slope failure landslide, holes supporting construction to lid and later normal operation use brings difficulty and risk.
Utility model content
The utility model solve the deficiencies in the prior art and provide it is a kind of design rationally, it is easy for construction, can effectively control
Ground settlement, hole Vault settlement, barrel sedimentation and the stability for improving cheuch section region slopes processed, reduce the suitable of construction disaster
The settlement Control structure holed with cheuch section lid.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of settlement Control structure for being applicable in cheuch section lid and holing, including be vertically cast in for lid arch two sides arch springing support
On reinforced concrete stirring device, use is arranged in the multiple rows of reinforced concrete stirring device laid on ground, along tunnel extending direction
In the sand-gravel cushion of Supporting cover arch, and the steel hinge line that lid arch is connected and fixed with preliminary bracing structure.
Further, the adjacent reinforced concrete stirring device of every row is equipped with overlapping region.
Further, the overlapping region length is 100mm.
Further, the length of the reinforced concrete stirring device is 3m, diameter 700mm.
Further, one end of the steel hinge line is fixed on the billet of lid arch arch springing by the first anchor cable fixing piece,
The other end of the steel hinge line by the second anchor cable fixing piece be fixed on tunnel get out of a predicament or an embarrassing situation preliminary bracing steel arch-shelf on.
Further, corrosion protective layer is set with outside the steel hinge line.
Further, the steel strand wires are equipped with certain prestressing force.
The utility model is by being arranged reinforced concrete stirring device in arch springing to guarantee the normal of lid arch before lid arch construction
Using and stability.After lid arch construction finishes, then the boring construction under lid arch, lid arch arch springing and tunnel are got out of a predicament or an embarrassing situation initial stage branch
Steel arch-shelf in shield is connected with prestress anchorage cable, can be efficiently controlled during tunnel operation afterwards in this way due to long-term
Vehicle dynamic load and the sedimentation generated.
In conclusion the utility model is designed reasonably, easy for construction, can efficiently control ground settlement, hole Vault settlement,
Barrel sedimentation and the stability for improving cheuch section region slopes, reduce construction disaster, effectively control in later operation
Prolonged vehicle dynamic load bring tunnel subsidence, moreover it is possible to save project cost, reduce lid hole work progress and with
Bring difficulty and risk are settled during normal operation afterwards.

Specific embodiment
The utility model in order to better understand is made utility model further detailed with reference to the accompanying drawing and embodiment
Describe in detail bright, but the embodiments of the present invention is not limited only to this, and the protection scope of the utility model is also related to art technology
Personnel according to the utility model design it is conceivable that equivalent technologies mean.
As shown in Figures 1 to 6, a kind of settlement Control structure for being applicable in cheuch section lid and holing, including lid arch 4, preliminary bracing
Structure 9 and two linings 5 are laid with two rows of reinforced cements in the ground for 4 support of lid arch, along the two sides countermeasure of tunnel extending direction
Native mixing pile 1, the reinforced concrete stirring device 1 include concrete-pile, the reinforced concrete soil pressure being arranged at the top of concrete-pile
Top plate 2, the joint bar 3 being arranged in concrete-pile are laid with the sandstone pad for being used to support lid arch 4 on reinforced concrete stirring device 1
Layer 13, after lid arch 4 is supported on the sand-gravel cushion, tunneling, and lay in tunnel preliminary bracing structure with
