Abstract
The invention discloses an underwater foundation spreading supporting structure for a temporary steel trestle. The underwater foundation spreading supporting structure for the temporary steel trestle comprises a steel pipe pile support. The steel pipe pile support is sleeved with a pile casing. Foundation spreading concrete is arranged between the steel pipe pile support and the pile casting. The steel pipe pile support is wrapped with the foundation spreading concrete. Short anchoring steel bars are welded to the portion, wrapped with the foundation spreading concrete, of the outer surface of a steel pipe of the steel pipe pile support and used for improving the wrapping force between the steel pipe pile support and the foundation spreading concrete. According to the underwater foundation spreading supporting structure for the temporary steel trestle, by the adoption of the way that a foundation concrete is added on the steel pipe pile support for foundation spreading, the bearing capacity of a steel pipe friction pile which is not hit to the design depth to support a foundation is improved and meets the design requirement; by the adoption of the underwater foundation spreading supporting structure, the problem that the bearing capacity of a steel pipe pile is not high enough due to the fact that the steel pipe pile is not hit to the design depth under poor geological conditions or under the geological conditions that floating rocks and boulders exist in the hitting process can be solved; the steel pipe pile support can meet the requirement for the bearing capacity under any geological conditions; the structure is safe and economical, and construction is easy, convenient and reliable.
Description
Technical field
The invention belongs to Construction of Civil Engineering field, be specifically related to a kind of steel trestle Extended chemotherapy braced structures, temporary steel trestle Extended chemotherapy braced structures in the water adopted when especially cannot complete for a kind of cross a river steel trestle steel pipe support inserted to play construction.
Background technology
Steel trestle supporting steel pile tube supports and is generally friction pile form, installs trestle superstructure after adopting vibrating hammer to assist rapping to design elevation during construction again.Geological conditions is run into the geological conditions such as stone boulder that waft in poor or injection process cannot set and extract rear change steel pipe pile position to the steel pipe pile often needed inserted to play certain depth during design altitude, re-start inserted to play.Cannot set if again run into and set position to still needing separately to select steel pipe pile during projected depth, work repeats, and waste is large, and the swapping process of steel pipe pile can cause certain damage to material.
Summary of the invention
The present invention is the deficiency in order to overcome existing for above-mentioned prior art, provide Extended chemotherapy braced structures in a kind of temporary steel trestle water, this structure can solve and cannot set to projected depth cause the problems such as Bearing Capacity of Steel Pipe Piles is inadequate owing to running into the geological conditions such as stone boulder that waft in features as poor geologic condition or injection process, meet requirement for bearing capacity under steel pipe pile can be made to be supported on any geological condition, safety economy, easy construction are reliable.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: Extended chemotherapy braced structures in a kind of temporary steel trestle water, comprise a steel pipe pile to support, steel pipe pile is set with casing outside supporting, support at steel pipe pile and have Extended chemotherapy concrete between casing, Extended chemotherapy concrete is wrapped up in and is attached in steel pipe pile support.
Be supported on Extended chemotherapy concrete at described steel pipe pile to wrap up in attached part outer surface of steel tube and be welded with anchoring bar dowel, support for increasing steel pipe pile and wrap up in attached power between Extended chemotherapy concrete.
Described Extended chemotherapy concrete is square or circular.
Described casing adopts make-up Flange joint.
Extended chemotherapy braced structures in a kind of temporary steel trestle water provided by the invention, on steel pipe pile supports, increasing the mode of base concrete Extended chemotherapy by adopting, making the bearing power increase that do not set to the tube fraction stake brace foundation of projected depth and meeting design requirement; Utilize this device to solve cannot set to projected depth cause the problems such as Bearing Capacity of Steel Pipe Piles is inadequate owing to running into the geological conditions such as stone boulder that waft in features as poor geologic condition or injection process, meet requirement for bearing capacity under steel pipe pile can be made to be supported on any geological condition, safety economy, easy construction are reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is that facade of the present invention arranges schematic diagram.
Detailed description of the invention
Facade arrangement diagram of the present invention as shown in Figure 1, Extended chemotherapy braced structures in a kind of temporary steel trestle water, comprise a steel pipe pile and support 1, steel pipe pile is set with casing 3 outside supporting 1, support between 1 and casing 3 at steel pipe pile and have Extended chemotherapy concrete 4, Extended chemotherapy concrete 4 is wrapped up in and is attached in steel pipe pile support 1.
In the present invention, support and wrap up in attached power for increasing steel pipe pile between 1 and Extended chemotherapy concrete 4, support 1 at steel pipe pile and wrap up in attached part outer surface of steel tube at Extended chemotherapy concrete 4 and be welded with anchoring bar dowel 2, Extended chemotherapy concrete 4 is square or circular.
Casing 3 of the present invention adopts make-up Flange joint.
Operating principle of the present invention is: by increasing base concrete Extended chemotherapy, makes the bearing power increase that do not set to the tube fraction stake brace foundation of projected depth and meets design requirement.
When the present invention uses, adopt vibrating hammer by steel pipe pile inserted to play to stopping the operation of steel pipe pile inserted to play when cannot sink, play the Large-diameter Steel casing 3 that make-up Flange joint is installed in lifting, and sink down into a face, riverbed, use and inhale mud air compressor machine at casing inside suction mud, Large-diameter Steel casing 3 sinks down into design attitude voluntarily, under diver, water steel pipe pile stayed surface in casing welds anchoring bar dowel and uses giant to rinse steel pipe pile stayed surface, in major diameter casing, underwater concrete is built after completing, form Extended chemotherapy, the sand 5 of the Extended chemotherapy top landfill certain altitude again on riverbed a, to prevent current scour, Extended chemotherapy is had an impact.
