Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is described in detail.
Embodiment one
As shown in Figure 1, the square 2 that a kind of Novel section steel antidetonation concrete block quay wall that the embodiment of the present invention provides comprises bedding 3, breastwork 1 and is installed between bedding 3 and breastwork 1, described square 2 from lower to upper stacked arrangement becomes multilayer.
In the present embodiment, described square 2 has two kinds, comprises the first square 21 and the second square 22.As shown in Figure 2, two through vertical holes 210 are provided with in the first square 21; As shown in Figure 3, in the second square 22, be provided with two through vertical holes 210 and a through horizontal hole 220, and vertical hole 210 in the second square 22 and horizontal hole 220 interconnect.Two in each square 2 vertical holes 210 are symmetrically distributed in the both sides of square 2 longitudinal central axis line.
As shown in Figure 4 and Figure 5, described first square 21 and the second square 22 from lower to upper successively intersecting be arranged between bedding 3 and breastwork 1, form the body of wall of harbour.Only comprise the one in the first square 21 or the second square 22 in every layer of square 2, install one deck second square 22 at interval of one deck first square 21, namely the first square 21 and the second square 22 are alternately arranged layer by layer.
Further, adjacent two layers square 2 mutually lateral alternate is arranged, and by vertical hole 210 consistency from top to bottom; Namely two vertical holes 210 in each first square 21 align with the vertical hole 210 of two the second squares 22 adjacent above or below this first square 21 respectively.Thus, the vertical hole 210 between each square 2 and horizontal hole 220 are interconnected.
Further, the shaped steel 42 of horizontally set is inserted with in the horizontal hole 220 being inserted with the vertical shaped steel 42 that arranges and reinforcing cage 41, second square 22 in the vertical hole 210 of the first square 21 and the second square 22; After setting shaped steel 42 and reinforcing cage 41, fill up hole by concreting in vertical hole 210 and horizontal hole 220, form steel reinforced concrete structure.
Vertical hole 210 and horizontal hole 220 need have certain safe distance apart from square 2 edge, and the safe distance of vertical hole 210 and horizontal hole 220 should be greater than 0.5 times of aperture width, and is not less than 500mm.Meanwhile, the spacing suggestion at two in each square 2 vertical hole 210 edges is greater than 1000mm.Need to arrange puzzle joint between square 2 and square 2, the specification of puzzle joint performs by related specifications.
The bottom square 2 be installed on above bedding 3 should be the first square 21, and should be provided with front toe, to increase resistance to overturning.Up install one deck second square 22 successively, one deck first square 21, is so staggered installation of; The final number of plies is determined by the height of harbour actual needs.
Particularly, described reinforcing cage 41 comprises the vertical principal rod arranged and the stirrup arranged along principal rod, and wherein, the stirrup arranging density near 300 ~ 500cm place of breastwork 1 is greater than the stirrup arranging density of other parts.
50 ~ 100cm in bedding 3 is stretched in the shaped steel 42 of vertical setting and the lower end of reinforcing cage 41, and 50 ~ 100cm in breastwork 1 is stretched in upper end.The shaped steel 42 of vertical setting and the size of reinforcing cage 41 and model can be determined according to square 2 size and harbour load case; Shaped steel 42 size of horizontally set with the consistent size of the shaped steel 42 vertically arranged or can reduce a model.
Junction between the shaped steel 42 of vertical setting and the shaped steel 42 of reinforcing cage 41 and horizontally set should be carried out operation by related specifications and be constructed, the shaped steel of customizable special construction if desired, ensure that junction is anyhow to linking and the intensity of shaped steel 42, to strengthen the lateral connection of square 2, reduce the effect that square 2 moves forward and backward.
Harbour suggestion provided by the invention adopts " dry application work " method to construct, namely adopt and fill formation land, cofferdam, or utilize favorable terrain condition, dock structure is built under the anhydrous condition of land, square 2 carries out prefabricated at precasting yard on request, hole place concrete adopts cast in place process, need ensure cast-in-situ concrete packed uniform, organically combines to construct to be undertaken by current specifications standard with shaped steel 42 and reinforcing cage 41.
The present invention is by vertical and horizontal hole reserved in square, shaped steel and reinforcing cage is inserted and fluid concrete fills up hole to strengthen the contact between square in hole, harbour is made to form a more firm entirety, mutual dislocation between minimizing square and the displacement of harbour entirety, improve the total bearing capacity of concrete block quay wall, be applicable to larger concrete block quay wall and build.This structure can keep out rear soil pressure largely, stops larger more modern boats and ships, and the use of harbour heavy construction machinery.Shaped steel stretches into the antiskid and anti-effect of inclining that can also play harbour entirety in the middle of bedding downwards, increases the stability of harbour.The Trinitarian work of shaped steel, concrete, reinforcing cage, complements each other, and has good later stage deformability; and ductility, to extreme cases such as earthquakes, there is good resistivity and protectiveness, increase the application life of concrete block quay wall; save material, there is obvious economic benefit.
Embodiment two
As shown in Figure 6, a kind of Novel section steel antidetonation concrete block quay wall that the embodiment of the present invention provides, improves on the basis of embodiment one.Particularly, be also provided with relieving slab 5 between the breastwork 1 in the present embodiment and square 2, this relieving slab 5 has the effect reducing square rear backfill pressure.
This improvement corresponding, the setting of reinforcing cage 41 and shaped steel 42 also changes to some extent, particularly, described reinforcing cage 41 comprises principal rod and the stirrup along principal rod arrangement, and the stirrup arranging density near 300 ~ 500 centimeters of relieving slab 5 is greater than the stirrup arranging density of other parts; 50 ~ 100cm in bedding 3 is stretched in the shaped steel 42 of vertical setting and the lower end of reinforcing cage 41, and 50 ~ 100cm in relieving slab 5 is stretched in upper end.
Other structures in the present embodiment are identical with embodiment one, do not repeat them here.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
