Abstract
Pipe -shed advance support structure in barrel section, this structure includes pipe -shed advance support district, concrete support region, and direction wall steelframe is the support main part of barrel section, and direction wall steelframe is fixed on the cement concrete piece of barrel section bottom, pipe -shed advance support district, concrete support region are the advance support structure of direction wall steelframe, pipe -shed advance support comprises well tub of canopy in the district, and equidistant the arranging of direction wall steelframe hoop is followed to each steel pipe of well tub of canopy, and concrete support region comprises early strength concrete, and concrete support region symmetry sets up bottom outside direction wall steelframe, and the pipe -shed advance support district sets up the intermediate position at direction wall steelframe, is the scope that pipe -shed advance support strutted in the district angle a 90 160. There is firm support frame the inboard of direction wall steelframe through bolted connection. The utility model discloses has good economic benefits and shortened construction period. Both save the spending, and can guarantee the safety of being under construction again, saved the time again simultaneously for the construction progress.
Description
Technical field
The utility model is related to advanced middle pipe canopy technical field, it is adaptable to barrel fault belt or Shallow-buried location,
Underground water develop location, and under wear important building location excavation construction.
Background technology
In the case where ensureing not affecting existing line to be open to traffic, works construction is safely carried out, it is general using advanced big
Pipe canopy or double-deck advanced tubule construction, high cost, work efficiency is low, the construction difficult problem such as operation inconvenience, and often the circulation engineering time is long, shadow
Ring construction speed.
Utility model content
In order to overcome the problems referred to above, the utility model proposes a kind of suitable advance support mode, efficiently solves
Problem is stated, and construction quality can also be protected, save expense, shorten the engineering time, accelerating construction progress.
The technical solution adopted in the utility model is barrel vault advanced support structure in barrel section, and the structure includes that pipe canopy is advanced
Supporting area I, concrete support area II, are oriented to supportive body of the wall steelframe 1 for barrel section, are oriented to wall steelframe 1 and are fixed on barrel section
On the coagulating cement soil block 4 of bottom；Barrel vault advanced support area I, concrete support area II are the advance support knot for being oriented to wall steelframe 1
Structure；Barrel vault advanced support area I is made up of middle pipe canopy 2, and each steel pipe of middle pipe canopy 2 is equally spaced along the ring of wall steelframe 1 is oriented to, and mixes
Solidifying soil Support II is made up of early strength concrete 3, and concrete support area II is symmetricly set on the exterior bottom of guiding wall steelframe 1, pipe
Canopy advance support area I is arranged on the centre position for being oriented to wall steelframe 1；The scope of barrel vault advanced support area I supporting angles a be 90 °-
160°.The inner side for being oriented to wall steelframe 1 has been bolted firm bracing frame 5.
Cement grout is marked with each steel pipe of middle pipe canopy 2.
The steel pipe of middle pipe canopy 2 is hot rolled seamless steel tube.
Cement grout is cement mortar and the ratio of mud is 1:1 cement grout.
The beneficial effects of the utility model are：
1st, this practical advanced middle pipe canopy, material is simple, handling ease, and it is convenient to construct；
2nd, this practical advanced middle pipe canopy, the engineering time substantially reduces.
3rd, this practical advanced middle pipe canopy, with good economic benefit and shortening construction period.Both spending had been saved, and
Construction safety is can guarantee that, while and save the time, accelerate construction speed.
Description of the drawings
