Abstract
The invention discloses a method for connecting a shield tunnel duct piece and a prefabricated flue header sheet. The connection method is characterized by comprising the following steps of: a, pre-embedding a connecting reinforcing steel bar and connectors in the shield tunnel duct piece; b, prefabricating a flue header sheet; c, connecting the pre-embedded connectors and a connecting bolt in the shield tunnel duct piece, and arranging positioning steel wedge blocks; d, transporting the prefabricated flue header sheet to a site after completing the construction of the shield tunnel duct piece, positioning through the steel wedge blocks, allowing the connecting bolt to pass through a prepared hole of the flue header sheet, and connecting the prefabricated flue header sheet and the connectors which are pre-embedded in the shield tunnel duct piece by using bolts and nuts; e, pouring fine stone concrete into gaps formed after the prefabricated flue header sheet is connected with the connectors in the shield tunnel duct piece for filling; and f, sealing all the exposed iron pieces with a fire-resistant material (FS3000 expansion joint fire-resistant glue) to position and assemble the shield tunnel duct piece and the flue header sheet. By the method, fast construction of connection between the dust piece and the prefabricated flue header sheet can be guaranteed; the connection method is economic, safe and reliable and brings convenience to construction; and by the method, the flue header sheet can be quickly positioned.
Description
Technical field:
The present invention relates to arrange in shield tunnel smoke vent technical field, be exactly specifically the method that duct pieces of shield tunnel positions, is connected with prefabricated flue header sheet.
Background technology:
Along with the development in city, adopt highway tunnel distance more and more longer of shield construction, and the requirement of fire disaster escaping is also more and more higher.In shield tunnel, smoke vent will be set, and smoke vent is constructed after shield tunnel construction completes, as adopt cast-in-place mode to construct, can greatly affect the construction period.
Summary of the invention:
The method that the object of the present invention is to provide high, economic, the safe section of jurisdiction of a kind of efficiency to be connected with prefabricated flue plate, meeting fast, the requirement of economy, safe construction.
To achieve these goals, technical scheme of the present invention is: the method for attachment of a kind of duct pieces of shield tunnel and prefabricated flue header sheet, is characterized in that: described method of attachment comprises the following steps: a, pre-buried connecting reinforcement and connector in duct pieces of shield tunnel; B, prefabricated flue plate (< < Standard for quality inspection and asswssment of precast concrete members > >, < < concrete structure and prefabricated component detection, defect repair are reinforced new technology and check evaluation criterion > >); C, in duct pieces of shield tunnel, by connecting bolt, be connected with pre-buried connector, then location steel voussoir is set; D is after duct pieces of shield tunnel has been constructed, prefabricated flue sheet is transported to behind scene, by gad piece, locate, by gad piece, locate, then pass the preformed hole of flue sheet and by nut, prefabricated flue plate be connected with connector pre-buried in duct pieces of shield tunnel by connecting bolt; E, prefabricated flue plate with in space after connector in duct pieces of shield tunnel is connected, water fine-stone concrete and fill, (requirement of strength of fine-stone concrete is C20); F, by all, expose location, the installation that just completes duct pieces of shield tunnel and flue sheet after fire proofing material for ironware (FS3000 shrinkage joint Waterproof gum) packing again.
The present invention adopt the on-the-spot location and installation of prefabricated flue plate can be more fast, economy, safety.It is a kind of comparatively desirable reliable method of attachment of location, convenient construction, economic security that completes fast flue sheet.
Accompanying drawing explanation:
