The present invention provides one kind and freezing aperture backstop, including feed pipe and freezing pipe, water in the feed pipe is controlled by water supply nozzle and water supply sluice valve, the outer pipe clamp of the non-return gate valve of freezing pipe outer cladding, it is connected by outer tube fixing bolt, the feed pipe is designed to plane contact with pipe clamp in non-return gate valve, pipe clamp is connected by telescopic rod and connecting rod with non-return gate valve respectively in the non-return gate valve, the telescopic rod and connecting rod surrounding are fixing shell, the non-return gate valve is connected by screw rod with non-return gate valve switch, the unlatching of backstop is controlled by non-return gate valve switch.During apparatus of the present invention can solve construction freezing method, phenomena such as leak sandblasting that reasons generate is damaged etc. by drill bit check defective valve and aperture antipriming, the engineering problems such as the leak sandblasting of freezing hole construction in later period are especially effectively treated.
Description
Technical field
The present invention relates to the technical fields of rail traffic, particularly belong to one kind and freezing aperture backstop.
Background technology
In the Practical Projects such as urban rail transit construction, the larger aquifer sand layer of groundwater pressure is encountered sometimes.At these
Stratum is constructed, and to occur drilling leak sandblasting very frequent for nearly horizontal frozen hole, can cause when serious greatly layer sink
Drop causes tunnel duct piece and surface structures deformed damaged even to lead to the catastrophic failure that tunnel collapses.
When using construction freezing method, sometimes because frost wall thaws, not due to the gap between freezing pipe and tunnel duct piece
It can timely and effectively block, also there is that there is a situation where leak sandblastings.Orifice tube generally occurs when starting to construct freezing hole to loosen
Fall off, the damage of fracture of freezing pipe, drill bit check defective valve and aperture antipriming situations such as it is less also disposable, but in freezing hole
It constructs the later stage, is easy to that collapse hole is caused to embrace brill so that the possibility of the above situation occurs since ground disturbance increases permeability raising
And its intractability dramatically increases.
Invention content
In order to solve the above-mentioned technical problem the present invention, provides one kind and freezing aperture backstop, be particularly suitable for freezing process
Construction, during apparatus of the present invention can solve construction freezing method, damaged by drill bit check defective valve and aperture antipriming etc.
Phenomena such as leak sandblasting that reason generates, the engineering problems such as the leak sandblasting of freezing hole construction in later period are especially effectively treated.
The technical scheme is that：One kind freezing aperture backstop, including feed pipe and freezing pipe, the feed pipe
In water controlled by water supply nozzle and water supply sluice valve, the outer pipe clamp of the non-return gate valve of freezing pipe outer cladding is fixed by outer tube
It is bolted, pipe clamp is designed to plane contact in the feed pipe and non-return gate valve, and pipe clamp passes through respectively in the non-return gate valve
Telescopic rod and connecting rod are connected with non-return gate valve, and the telescopic rod and connecting rod surrounding are fixing shell, and the non-return gate valve is logical
It crosses screw rod with non-return gate valve switch to be connected, the unlatching of backstop is controlled by non-return gate valve switch.
Further, the water in the feed pipe is controlled by water supply nozzle and water supply sluice valve.
Further, the outer pipe clamp of the non-return gate valve of freezing pipe outer cladding, is connected by outer tube fixing bolt.
Further, the feed pipe is designed to plane contact with pipe clamp in non-return gate valve.
Further, pipe clamp is connected by telescopic rod and connecting rod with non-return gate valve respectively in the non-return gate valve.
Further, the telescopic rod and connecting rod surrounding are fixing shell.
Further, the non-return gate valve is connected by screw rod with non-return gate valve switch, is controlled by non-return gate valve switch
The unlatching of backstop.
Description of the drawings
Invention is further described in detail below in conjunction with the accompanying drawings：
Fig. 1 is schematic structural view of the invention；
In figure：
1- freezing pipes, 2- feed pipes, 201- water supply nozzles, 202- water supply sluice valves, the non-return gate valves of 3-, the non-return gate valve outer tubes of 301-
Block, the non-return gate valve switch of 302-, pipe clamp in the non-return gate valves of 303-, 304- outer tube fixing bolts, 305- connecting rods, 306- is flexible
Bar, 307- fixing shells, 308- screw rods.
Specific implementation mode
As shown in Figure 1, one kind freezing aperture backstop, including feed pipe 2 and freezing pipe 1, the water in the feed pipe 2
It is controlled by water supply nozzle 201 and water supply sluice valve 202, the outer pipe clamp 301 of the non-return gate valve of 1 outer cladding of the freezing pipe passes through outer tube
Fixing bolt 304 connects, and the feed pipe 2 is designed to plane contact, the non-return gate valve inner tube with pipe clamp 303 in non-return gate valve
Card 303 is connected by telescopic rod 306 and connecting rod 305 with non-return gate valve 3 respectively, 305 surrounding of the telescopic rod 306 and connecting rod
For fixing shell 307, the non-return gate valve 3 is connected by screw rod 308 with non-return gate valve switch 302, and non-return gate valve switch is passed through
302 control the unlatching of backstop.
Above example is not limited only to protection scope of the present invention, all to be repaiied based on basic thoughts of the invention
Change or what is changed belongs to protection scope of the present invention.
