Abstract
The utility model belongs to a civil engineering construction and relates to a semi-separating type reverse-L shaped breast wall and a harbor seawall constructed by adopting the breast wall. The breast wall is different from a common reverse-L shaped breast wall; the breast wall is provided with a rear toe which is of conventional ladder shape, rectangular shape, and the like; the rear toe is integrally connected with the reverse-L shaped breast wall of a front half part; holes penetrating into the bottom of the breast wall are arranged at joints of the rear toe and the root of the reverse-L shaped breast wall of the front half part; the holes are of rectangular or circular shape; and the specific sizes of the holes, including length, size, height and intervals between holes, are confirmed by calculating according to a specific engineering condition. The holes are utilized to dissipate the wave buoyancy at the bottom of the breast wall and reduce a capsizing moment of the breast wall, thereby being beneficial to the capsizing resistance of the structure; the stable force moment of the structure is increased by the dead load of the rear toe of the breast wall, thereby being beneficial to the sliding resistance of the structure; and finally, the purposes of reducing the cross section of the breast wall and saving the work amount are achieved.
Description
Technical field
The utility model belongs to a kind of civil engineering work thing technical field, relates to the anti-L type of a kind of half separate type breastwork, is applicable on the harbour mole.
Background technology
Breastwork is the superstructure of mole, and it is positioned at the fluctuation of water table district, directly bears the effect of wave load, requires to have enough stability.The structural shape of conventional breastwork has L type, anti-L type, camber etc., and all with deadweight opposing wave lift, so uplift pressure has very big influence to the breastwork design of structural size.Because the whole bottom surface of breastwork of these patterns all receives the effect of uplift pressure, so physical dimension is bigger, the concrete material consumption is more.
The anti-L type of the half separate type breastwork structure of the utility model exploitation is established hallux at the back at the anti-L type breastwork of first half, the anti-L type breastwork of hallux and first half be connect into holistic.The anti-L type breastwork root junction of breastwork hallux and first half offers the hole that extends through breastwork bottom, through the wave lift of hole dissipation breastwork bottom, reduces the overturning moment of breastwork, helps that structure is anti-inclines; The deadweight of breastwork hallux can increase the stabilizing moment of structure, helps the structure antiskid.Finally can reach and reduce the breastwork section, the purpose of saving engineering quantity.
The utility model content
The utility model provides the anti-L type of a kind of half separate type breastwork structure, and this form of structure can reduce the uplift pressure of wave effectively, can be used on several types of breakwater structures such as vertical breakwater, sloping breakwater, special shape mole.In actual engineering, directly be placed in the anti-L type of this half separate type breastwork structure the top of mole substructure, as wave wall.
The technical scheme of the utility model is following:
Half separate type anti-L type breastwork of the utility model and common anti-L type breastwork are different; It is a kind of anti-L type breastwork that has hallux; This breastwork hallux adopts shapes such as common trapezoidal, rectangle, and the anti-L type breastwork of breastwork hallux and first half connects into as a whole.The anti-L type breastwork root junction of breastwork hallux and first half offers the hole that extends through the breastwork bottom.Hole can adopt shapes such as rectangle, circle.The concrete size of hole comprises spacing between length, width, height and the hole etc., calculates according to concrete engineering specifications and confirms.
The anti-L type of this half separate type breastwork structure is applicable on the harbour mole that the structural form of this harbour mole is: the anti-L type of basis-substructure-half separate type breastwork.
The beneficial effect of the utility model is: through the wave lift of hole dissipation breastwork bottom, reduce the overturning moment of breastwork, help that structure is anti-inclines; The deadweight of breastwork hallux can increase the stabilizing moment of structure, helps the structure antiskid.Finally can reach and reduce the breastwork section, the purpose of saving engineering quantity.
Description of drawings
Fig. 1 is the profile of the utility model.
Fig. 2 is the plan view of the utility model.
Fig. 3 is the elevation of the utility model.
Among the figure: the anti-L type breastwork of 1 first half; 2 holes; 3 breastwork halluxs.
The specific embodiment
Be described in detail the specific embodiment of the utility model below in conjunction with technical scheme and accompanying drawing.
Embodiment: at first to long 10m, the anti-L type of the half separate type breastwork of wide 8.4m carries out the construction line-putting, presses working drawing design size location; Root is reserved 7 discontinuous holes that extend through the breastwork bottom of a row, the long 1m of hole, wide 0.2m, high 0.7m, spacing 0.3m then according to breastwork structure chart branching standing template, and in the anti-L type breastwork junction of breastwork hallux and first half; Upright and the assembling reinforcement according to breastwork arrangement of reinforcement chart rack, 28 I grade reinforcing steels that diameter is 40mm are arranged in the anti-L type breastwork root junction of breastwork hallux and first half, thickness of protection tier is 50mm; At last in template, build the concrete that label is C30D300, breastwork shrinkage joint spacing is 10m, and the shrinkage joint width is 30mm; Fill the oil immersion woodwool board in the shrinkage joint; And in hole, fill out towards rubble, the moist maintenance of concrete 28 days treats that concrete strength reaches form removal after the designing requirement.
