Description
Technical field
The utility model belongs to underground prefabricating square culvert, and particularly a kind of Urban Underground takes shield machine shield structure tunnel out to make the assembled concrete prefabricated square culvert of land used Tunnel Boring.
Background technology
At present, that the Urban Underground construction of many developed countries of the world has all adopted is advanced, economize on resources, be conducive to create harmonious ecology environment and environmental protection, and the phenomenon of solved repeatedly ditching pipe laying, burying cable occurs; So occurred at embedded underground prefabricating square culvert, formed Urban Underground piping lane.The construction of underground pipe gallery in the past exists that fluting area is large, engineering (earthwork) amount greatly, the deficiencies such as long construction period.So adopt now shield machine, the tunnel that once shield structure goes out to install Fang Han on ground.But existing concrete square is contained, and cannot be transported in tunnel and install, bring technical barrier to advanced technology.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides one can in Fang Han, transport prefabricating square culvert member, the assembled concrete prefabricated square culvert of Tunnel Boring quick for installation in shield structure tunnel.
The technical scheme that the utility model technical solution problem adopts is: the assembled concrete prefabricated square culvert of a kind of Tunnel Boring, it is characterized in that first segment Fang Han makes one end for straight mouthful, the other end is angle, the upper en culvert member being connected with angle and lower en culvert member are all made the U-shaped groove of parallelogram, the angle of long limit and minor face is α, and the width that upper en is contained member and lower en culvert fresh kidney beans is L; Above the left side of upper en culvert member, be provided with en and contain boss; Be provided with en below and contain groove, above right side, be provided with en and contain groove, be provided with lower en below and contain groove; The lower left that lower en is contained member is provided with lower en culvert boss, is provided with lower en above and contains groove, is provided with lower en and contains boss above right side, is provided with lower en below and contains groove; Upper en contains that member is contained between member with lower en, adjacent two upper ens are contained between members and between adjacent two lower ens culvert members and are equipped with connecting groove; The joint of each concrete component is equipped with the stairstepping socket of boss and groove; In connecting groove, with junction plate, stud, pad and nut, its each member is fixed together; Junction plate two ends are welded with the fixing reinforcing bar of junction plate; The fixing reinforcing bar of junction plate is fixed in concrete component.Upper en contains member and lower en is contained the long limit of member and the angle α=30--80 ° of minor face.Upper en is contained the width L=500--5000mm of member and lower en culvert member.
The beneficial effects of the utility model are: this invention has solved the technical barrier that adopts shield machine shield formation underground passage of shield machine that square piping lane is installed, and not be used in ground ditching fluting, saves the cost that piping lane is built, and speed is fast.
