Abstract
The utility model belongs to a three-segmentation underdrain concrete prefabricated quadrate culvert, which comprises an inverted U-shaped top cover (3) and is characterized in that an L-shaped left wall (1) and an L-shaped right wall (6) are correspondingly and fixedly arranged under the top cover (3). The segments of the L-shaped left wall (1) and the L-shaped right wall (6) in contact with the ground are fixedly equipped with a plurality of steel bars (7). A cast-in-situ bottom plate (8) made of concrete is casted on the steel bars (7). When the three-segmentation underdrain concrete prefabricated quadrate culvert is used for building a large-scale underdrain, the integral performance of the large-scale underdrain is better. Meanwhile, components are convenient in production, transportation and installation. The construction is easy in management and fast in speed.
Description
Technical field
The utility model belongs to building unit, and concrete prefabricated Fang Han is cut apart in three of particularly a kind of large-scale kanat use.
Background technology
In urban construction, particularly often need be at the underground covered nullah that is provided with to metropolitan municipal engineering construction.Present job practices is to adopt cast-in-place method, and the problem that this method exists is a long construction period, and the fluting area is big, and the field control difficulty is big, and poor quality's control is prone to produce disadvantages such as permeable; Another kind method is to adopt prefabricated side to contain member to construct, and its weak point is that component volume, weight are big, gives transportation, produces, installs and bring many difficulties, and overall performance is poor, and speed of application is slow.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of overall performance good, single-piece is in light weight, helps transportation, produces, installs, and what speed of application was fast three cuts apart the concrete prefabricated Fang Han of closed conduit.
The technical scheme that the utility model technical solution problem is adopted is: a kind of three cut apart the concrete prefabricated Fang Han of closed conduit; Comprise inverted U-shaped loam cake; It is characterized in that corresponding L shaped left wall and the L shaped right wall of fixedly being equipped with below inverted U-shaped loam cake; Be fixed with many reinforcing bars at L shaped left wall and L shaped right wall and ground contact-segment, on reinforcing bar, become cast-in-place base plate with concrete cast-in-situ.
The beneficial effect of the utility model is: it is good to cut apart the concrete prefabricated Fang Han construction of closed conduit covered nullah overall performance with three, the production of member, transportation, easy for installation; The good management of construction, speed is fast.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 three is cut apart the concrete prefabricated side of closed conduit and is contained front view;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: the wall of a 1-L shape left side; The 2-suspension ring; The inverted U-shaped loam cake of 3-; The vertical steel strand tension of 4-hole; The vertical steel strand tension of 5-hole; The right wall of 6-L shape; The 7-reinforcing bar; The cast-in-place base plate of 8-; The 9-taper receives mouth; The 10-cone-shaped plug.
The specific embodiment
Embodiment; With reference to accompanying drawing; A kind of three cut apart the concrete prefabricated Fang Han of closed conduit, comprise inverted U-shaped loam cake 3, it is characterized in that corresponding L shaped left wall 1 and the L shaped right wall 6 of fixedly being equipped with below inverted U-shaped loam cake 3; Be fixed with many reinforcing bars 7 at L shaped left wall 1 and L shaped right wall 6 with the ground contact-segment, on reinforcing bar 7, become cast-in-place base plate 8 with concrete cast-in-situ.Steel strand are put in the corresponding vertical steel strand tension hole 5 that is provided with on inverted U-shaped loam cake 3, L shaped left wall 1 and the L shaped right wall 6 in the hole, lean on tension force that its inverted U-shaped loam cake 3 and L shaped left wall 1, L shaped right wall 6 are fixed together; The taper that cone-shaped plug 10 inserts adjacent Fang Han receives in the mouth 9, is vertically putting on steel strand in the steel strand tension hole 4, strains vertical connection that adjacent each side is contained, and is fixed with suspension ring 2 above the inverted U-shaped loam cake 3, is convenient to lifting and uses.
This three cuts apart the concrete prefabricated Fang Han of closed conduit, and the construction that is mainly used in covered nullah is used, and speed of application is fast, and quality is good.
Claims (1)
1. cut apart the concrete prefabricated Fang Han of closed conduit for one kind three; Comprise inverted U-shaped loam cake (3); It is characterized in that corresponding L shaped left wall (1) and the L shaped right wall (6) of fixedly being equipped with below inverted U-shaped loam cake (3); Be fixed with many reinforcing bars (7) at L shaped left wall (1) and L shaped right wall (6) with the ground contact-segment, upward become cast-in-place base plate (8) with concrete cast-in-situ at reinforcing bar (7).
