Description
Technical field
The utility model relates to underground engineering construction field, particularly the first conduit proscenia of box culvert.
Background technology
In municipal administration and underground engineering construction field, in weeping formation and soft soil layer, build down and wear the underground passage of the main line of communication and without interruption when face traffic, often adopt tunneling construction technology, as pipe shed method, Guan Mufa, pipe roof culvert box advancing method, pipe curtain box culvert double replacement method etc.These constructions respectively have its pluses and minuses and applicability, but these construction methods steel pipe quantity used is many, need repeatedly push pipe operation, and construction speed is slow, and steel pipe mostly is temporary measure, and rolled steel dosage is large, how can not reclaim, and direct cost is high.Although a steel pipe for pipe curtain box culvert double replacement method can reclaim, need to be by all soil bodys displacements within the scope of whole box culvert, the steel material needing is also very large, and the earthwork all excavates in each steel pipe, construction speed is slow.
Utility model content
The purpose of this utility model is to provide a kind of in weeping formation and soft soil layer, the first conduit proscenia of box culvert utilizing wear the underground passage of the main line of communication under building under face transportation condition without interruption time, improving under the prerequisite of working security, significantly reduce rolled steel dosage, shorten construction period, reduce construction cost, reduce the impact on environment.
For achieving the above object, the utility model adopts following technical scheme:
The first conduit proscenia of box culvert, be installed on box culvert outline line front end, the steel pipe of Gong the constructor turnover being formed by multiple Plate Weldings forms, steel pipe front end is provided with cutting edge, steel pipe rear end is connected with box culvert, multiple jack are set between steel pipe and box culvert, and for the jacking of first conduit proscenia and correction, steel pipe rear end has one deck steel plate to stretch to the outer shade of box culvert outside formation.This device is provided with construction outlet along the steel pipe rear side of top and both sides layout, being provided with construction outlet, and stretching out shade in formation along the steel pipe rear end of lower disposed in box culvert, and steel pipe is being provided with Grouting Pipe with country rock contact side.
Between steel pipe, also can be bolted.
The length of steel pipe can be isometric or not isometric.
The course of work of the present utility model is as follows:
When construction, starting in active well, after first this box culvert conduit proscenia and prefabricated box culvert are connected, utilize jacking mechanism to promote box culvert, by the jack between box culvert and first pipe guide, first conduit proscenia is first headed in soil layer again, in steel pipe, form soil plug, then under the protective effect of steel pipe, manage interior soil excavation, and by steel pipe rear end or the construction outlet of side, rear end, the earthwork is transported, realize the local displacement of first conduit proscenia soil layer, the box culvert of follow-up is replaced first conduit proscenia again, realize double replacement soil layer, under the first conduit proscenia of box culvert and box culvert supporting, carry out a cubic metre of earth heavy excavation simultaneously.
In soil excavation in the first pipe guide steel pipe of box culvert and box culvert, a cubic metre of earth heavy excavation can carry out simultaneously, and soil excavation and box culvert jacking can synchronously be carried out, and can realize the continuous production process of box culvert jacking.The first pipe guide of box culvert arrives after received well, removes received well enclosed structure, disassembles successively the first pipe guide of box culvert in received well, and box culvert jacking finishes.
The utility model is in weeping formation or soft soil layer when crest enters box culvert, the first conduit proscenia of box culvert that utilizes box culvert front end to install, first displace one section of earthwork in box culvert structure component range, and then the box culvert that utilizes follow-up is replaced the first conduit proscenia of box culvert, realize secondary and replace continuously soil layer, under the supporting of the first conduit proscenia of box culvert and box culvert, carry out the soil excavation of multiple work planes simultaneously, realize the continuity of construction.
(1) soil excavation excavates under the protection of the first conduit proscenia of box culvert and box culvert, and construction safety, easily controls ground settlement.
(2) first conduit proscenia length is short, general only needs 2～6 meters long, and rolled steel dosage is few compared with pipe shed method, Guan Mufa, pipe roof culvert box advancing method, pipe curtain box culvert double replacement method steel using amount, and can reuse, and direct cost is low.
(3) the method is replaced soil layer twice, and pipe curtain box culvert double replacement method is simple, and construction continuity is good, and the main earthwork adopts a heavy excavation form to complete, and speed of application is fast, and the duration is short, and cost is low, good in economic efficiency.
(4) underground passage of building, does not need to interrupt traffic above-ground, and environmental benefit is good.
