Description

A kind of assembled active well structure

Technical field

This utility model relates to technical field of civil engineering, relates in particular to the underground piping such as urban transportation, plumbing And a kind of export & import assembled active well structure in city integrated piping lane field and construction method.

Background technology

When city tunnel, piping lane non-excavating construction, the speed of application pair of the export & import active well of shield and pipe jacking equipment The progress impact of whole engineering is very big, and especially for heavy traffic, densely populated, above ground structure is numerous, underground structure The complicated urban environment condition complicated with pipeline.

Caisson structure, as end well or a kind of common structure of active well, reaches extensively to apply.This structure is usually Floor manufacture, sinks to predetermined absolute altitude by fetching earth in well thus forms underground structure.This structure has particular advantages: put ground Area is little, and excavation fetches earth and need not foundation pit enclosure；Without special professional equipment, easy and simple to handle；Both can be as underground structure Leg, open caisson inner space also can be made full use of.In recent years, along with construction technology and the continuous innovation of construction machinery, Open caisson is at home and abroad obtained for and is widely applied and develops.

Traditional caisson structure be by a kind of cut the soil body by the way of sink, rely on dead load or vibrating drag reduction technology Measure overcomes the frictional resistance between the soil body and the borehole wall and cutting shoe counter-force, slowly sinks, and fetches earth in down-hole, reaches designed elevation, in well Back cover.In caisson structure sinking watching, in order to drag reduction is by relatively big to the soil disturbance of borehole wall periphery, cause open caisson outer periphery Environment be a greater impact, especially in dense population areas or downtown, open caisson periphery is embedded with a large amount of pipeline, and distribution is each Class important building and structures.In soft clay area, working as well sinking, in well, the soil body excavates process, produces the water and soil inside and outside well When pressure differential is bigger, the water and soil cognition outside well is walked around the cutting shoe of open caisson and is flowed in well, the stratum settlement outside well can be made to increase, cause Building and pipeline outside well produce damage and even destroy.Simultaneous is cut the earth and Precipitation Process, often leads to open caisson knot Structure is prominent heavy or tilts, and makes the speed of open caisson construction suffer significant impact.Additionally, current caisson structure many employings cast in situs side Method is made, and needs maintenance, thus needs the longer construction period.For fall in the stratum of phreatic high, the well of digging process Water, the impact on well external environment can be bigger.Therefore, use the method for drop shaft sinking construction working well by stratum characteristic, subsoil water Compose and deposit and the restriction of the condition such as surrounding enviroment protection.Existing caisson structure can be overcome to execute to this end, engineering circles needs searching one badly Deficiency that work exists, eliminate open caisson construction new construction that surrounding enviroment affects and new method, improve speed of application, shorten and construct Duration.

In the higher area of level of ground water and soft stratum, the method construction working that the most conventional open-cut foundation ditch is gone along with sb. to guard him Well, vertical building enclosure of first constructing, then limit excavation, facility in limit construction level supporting construction and mounting shaft.Due to existing Foundation pit enclosure structure speed of application is relatively slow, has had a strong impact on the construction period of subterranean tunnel or piping lane.The building enclosure of active well, Pass through for the ease of shield machine, replace conventional reinforcing bar to manufacture building enclosure frequently with glass fiber-reinforced polymer, but cost is higher.Especially It punches wall from going along with sb. to guard him passing in and out doorway positions through walls, not only have impact on the safety of building enclosure and surrounding enviroment, Er Qieshi Work process is longer, and this is also a difficult problem anxious to be resolved in subterranean tunnel and piping lane construction.

Utility model content

Technical problem to be solved in the utility model is, overcomes existing caisson structure and open-cut foundation ditch building enclosure to execute Work cycle length, big on surrounding enviroment impact, easily occur quicksand to cause inclination of open caisson or the deficiency of difficulty etc. of sinking, it is provided that a kind of fast Speed assembly work well construction, it is possible to effectively control member is implanted with shoveling process in well surrounding enviroment adverse effect, it is ensured that well Punch on wall safe technology and method.
