Abstract
The invention belongs to a telescopic concrete precast square culvert which comprises bottom plates (1), a left side wall (2), a right side wall (6) and upper covers (4). The telescopic concrete precast square culvert is characterized in that a telescopic elastic joint (8) is fixed in the middle of the bottom plates (1), the left side wall (2), the right side wall (6) and the upper covers (4). The telescopic concrete precast square culvert is installed on two sides, at corners, at a hard and soft zone intersection or near soft foundation of a manhole for application, and the telescopic concrete precast square culvert cannot be damaged due to change of ground stress.
Description
Technical field
The invention belongs to building unit, particularly a kind of scalable concrete prefabricated Fang Han that is used for urban operating mechanisms uses such as city underground pipe gallery, electric power tunnel.
Background technology
In urban operating mechanisms such as the underground comprehensive pipe exterior feature in city, electric power tunnel are built; Often have manhole, corner, the soft or hard area crosses and soft foundation near; If in these places; Adopt general concrete prefabricated Fang Han, or adopt cast-in-place method to connect, the variation of stress will often occur in these places and breakage is contained in the side of causing and influence the use of piping lane or electric power tunnel.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, use near a kind of both sides at manhole, corner, soft or hard area intersection and soft foundation are provided, can be crooked with the variation of geostatic stress, the scalable concrete prefabricated Fang Han that can not damage.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of scalable concrete prefabricated Fang Han; Comprise base plate, left side wall, right side wall and loam cake, it is characterized in that having flexible elastic telescopic joint in one of the center fixed of base plate, left side wall, right side wall and loam cake.
The invention has the beneficial effects as follows: this scalable concrete prefabricated Fang Han is contained near the use of both sides, corner, soft or hard area intersection and soft foundation of manhole, can not damage because of the variation of geostatic stress.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is that scalable concrete prefabricated side is contained front view;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: the 1-base plate; The 2-left side wall; The 3-suspension ring; The 4-loam cake; The vertical steel strand tension of 5-hole; The 6-right side wall; The 7-taper receives mouth; The 8-elastic telescopic joint; The 9-cone-shaped plug.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of scalable concrete prefabricated Fang Han comprises base plate 1, left side wall 2, right side wall 6 and loam cake 4, it is characterized in that the flexible elastic telescopic joint 8 of center fixed at base plate 1, left side wall 2, right side wall 6 and loam cake 4.Scalable concrete prefabricated side is contained place, four angles and is provided with vertical steel strand tension hole 5, and steel strand in the hole is vertically strained adjacent Fang Han; The left end head is provided with taper and receives mouth 7, and the right-hand member head is provided with cone-shaped plug 9, when Fang Han is connected with Fang Han cone-shaped plug 9 is inserted into another side's culvert taper and receives in the mouth 7; Be fixed with suspension ring 3 above the loam cake 4, lifting is used when being convenient to install.
This scalable concrete prefabricated Fang Han is contained near the use of both sides, corner, soft or hard area intersection and soft foundation of manhole, can not damage because of the variation of geostatic stress.
Claims (1)
