Description
Technical field
The utility model belongs to Shield Construction Technique field, passes through river construction more particularly, to a kind of Shield-bored tunnels
Use grouting equipment.
Background technique
Shield method is a kind of Fully-mechanized construction method of modern constructing tunnel, and leading mechanical equipment to be used is shield
Machine uses the molding subway tunnel of shield construction for Shield-bored tunnels.The shield body of shield machine by anterior shield, middle shield and shield tail from
Assemble front to back, anterior shield front is equipped with cutterhead.When shield construction, the purpose of slip casting is starched by the slip casting injected
The purpose of liquid is filled the intracorporal gap of soil, realizes soil stabilization, control soil body sedimentation.
According to general knowledge known in this field, the grouting serous fluid injected during shield-tunneling construction at present (abbreviation slurries) includes single
Slurry and two kinds of dual slurry, wherein dual slurry includes that the dual slurry of cement and waterglass composition, a gram mud effect are formed with waterglass
Dual slurry etc..Wherein, gram mud effectiveness is derivative by synthesizing calcium base clay mineral, cellulose in Tunnel Engineering periphery filler
Agent, colloid stabilizer and dispersing agent are constituted, advantage: if first is that settled in shield machine driving, cavity, the danger feelings such as gush
When condition, what the characteristics such as sealing, filling and support of the material can be instant reaches the branch remedied, and will not generate prohibitively expensive
Out, usage mode is also simple and fast；Second is that in addition other expensive equipment need not be added, use on shield machine with can be convenient
High-speed mixer mixes to realize that gram mud imitates a slurries (i.e. gram mud imitates the slurries being mixed to form with water, and also referred to as gram mud imitates solution), and
Injected via pump, injection valve group and injection pipe above gram mud effect slurries and waterglass to native storehouse injection hole or shield machine surrounding into
It is mixed and is injected to mouth, effectively achieve the effect that sealing, filling and support.
River refers to the route that river water flows through, and is often referred to the water route that can be opened the navigation or air flight.Using shield method to the subway for passing through river
When tunnel is constructed, since constructed subway tunnel is located at below river, to avoid constructing tunnel process bring water source dirty
The problems such as dye, river sedimentation, difficulty of construction is larger, and construction environment safety requirements is higher.Nowadays, using shield method to wearing
When the subway tunnel in more river is constructed, focus on ensure construction environment safety, not polluted source, do not influence river and use
Aspect, there are mainly two types of conventional construction method: the first is the method improved to the following soil body of river original ground, such as
The original ground following soil body in river is improved using high-pressure rotary jet grouting pile, high-pressure slip-casting etc.；Second is to shield machine front end soil
The method of body progress pre-grouting.But when practice of construction, there are river sedimentations to be difficult to control for first method, settles larger, water
The problems such as source pollution is more serious, second method pre-grouting synchronous cannot be carried out with the work progress of shield-tunneling construction, and shield is applied
Work low efficiency, used resource and expense are larger, and input cost is high.Such as using shield method to the tunnel in the south water to north trunk canal passed through
When engineering is constructed, since the settlement request in south water to north trunk canal is high, water source is forbidden polluting, and above-mentioned first method can not be real
It applies, and second method be since pre-grouting and shield-tunneling construction synchronous cannot carry out, construction efficiency is low and input cost is high.
