Abstract
The invention discloses a gantry for casting a breast wall. The gantry comprises a gantry body and a travelling system. The gantry body comprises a bearing truss which is a retaining ring beam structure. A support leg is arranged under the bearing truss. A pulley is arranged at the lower end of the support leg. The travelling system comprises a driving system and a track. The gantry body is glidingly supported on the track through the pulley. A control circuit of the pulley is connected with the driving system. A lifting point for installing a chain block is arranged under the bearing truss. By means of the movable gantry, a template is lifted by utilizing the chain block installed on the gantry body; the problem of being difficult to lift and install the template is solved; furthermore, problems, such as low construction efficiency, high cost, large equipment occupation area and the like, are also solved; meanwhile, an H beam arranged on the gantry provides a construction platform for lifting block stones; the construction efficiency is further increased; the cost is further reduced; the equipment occupation area is further reduced; and the gantry is applicable to casting the breast wall.
Description
Technical field
The invention belongs to breastwork and build the field, be specifically related to door frame and construction technology thereof that a kind of breastwork that is used for sloping breakwater is built.
Background technology
At present, on engineerings such as sloping breakwater, breastwork is built through regular meeting and is run into following problem:
1, because the breastwork size of sloping breakwater is bigger, so it is also bigger to be used to build the template size and the tonnage of breastwork, will cause like this template installation, dismounting, move the large-scale crane gear of needs, transport a template but also once can only lift by crane;
2, because the construction channel width of engineerings such as sloping breakwater is less, if so adopt crane gears such as portable tower crane, straddle truck, mobile crane, can take limited construction passage, cause the operation of other working procedures to carry out (as the transportation of specification stone, the installation of armour etc.), if and the employing crane ship carries out installation, the dismounting, mobile of template, cost height then, work efficiency is low, can't satisfy the construction speed requirement;
3, because the breastwork of sloping breakwater is the large volume plain concrete, in order to reduce the heat of hydration, need in concrete, add 20% piece stone according to designing requirement, the lifting of these piece stones also needs crane gear, can take limited construction passage equally, influence the operation of other working procedures.
4, since engineering such as sloping breakwater all in the coastal region, all will experience the typhoon phase in every year, in order to guarantee in work progress, can it's the typhoon phase to past degree of safety, need before arriving, finish typhoon building of lower floor's breastwork (because the breastwork sectional dimension is big, one-time-concreting is difficult, so divide two-layer building), so just require to improve efficiency of construction.
