Abstract
The utility model relates to equipment equipped with a steel platform for the foundation construction of a land bridge, and belongs to the technical field of bridge construction measures. The equipment comprises a plurality of steel protection cylinders fixed on a precipice of a mountain. Each steel protection cylinder is provided with a lower main beam which is provided with a bailey beam. Each bailey beam is provided with a distribution beam which is provided with a steel platform panel. A construction operating platform is provided through a structural mode of the steel platform.
Description
Technical field
The utility model belongs to bridge construction measure technical field, is specifically related to a kind of steel platform of setting up and carries out land bridge foundation construction equipment.
Background technology
First land bridge needs construction plant to fill out and dig processing before foundation construction, adopts direct excavation, Blasting Excavation, directly backfill more, builds the technique formation construction operation platforms such as retaining wall backfill by laying bricks or stones.In Bridges in Mountainous Areas construction, impact due to orographic condition, geological condition, when pile foundation exposes that earth's surface radical is many, stake top expose highly large, the massif gradient is large, excavation at need, adopt excavation, backfill and build retaining wall technique basis of formation construction operation platform inapplicable.
Utility model content
The purpose of this utility model is exactly the defect for prior art, provides a kind of steel platform of setting up to carry out land bridge foundation construction equipment.When land bridge pile foundation exposes that earth's surface radical is many, stake top expose highly large, the massif gradient is large, excavation difficulty is difficult for adopting digging up and filling in, build retaining wall method carries out construction plant and process this kind of construction technology of appropriate to the occasion employing and carry out foundation construction.
The technical solution adopted in the utility model is: it comprises the some sections steel casings that are fixed on massif precipice, described steel casing is provided with lower floor's girder, described lower floor girder is provided with Bailey beam, and described Bailey beam is provided with distribution beam, and described distribution beam is provided with steel platform panel.
Further preferred structure, described some sections steel casings upper end flushes.
Further preferred structure, is provided with bracket diagonal brace between described steel casing side and lower floor's girder.
The utlity model has the advantages such as technical difficulty is low, security risk is low, processing cost is low, the processing time is short, the difficulty running into from technology, safety, the many-sided work progress solving of economic dispatch.Make the construction plant processing that engineering quantity is large originally, cost is high, technical difficulty is high, security risk is large become simple, easy to operate, the controllable construction of technique, not only guaranteed reliability of structure, also shortened greatly the construction plant processing time, avoided a large amount of embankment operation to the interference of job site water environment and pollution, environmental protection effect is obvious simultaneously.The form of structure of steel platform can be used as again the measure of bridge main body structure construction when construction operation platform is provided, practical, economic effect is obvious.Steel casing method for embedding has effectively solved the problem that is connected and fixed of steel casing and ground, and personnel, equipment, material input amount are little, and economic effect is obvious.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As shown in Fig. 1-Fig. 4, the utility model comprises the some sections steel casings 1 that are fixed on massif precipice, and described steel casing 1 is provided with lower floor's girder 3, and described lower floor girder 3 is provided with Bei Lei 4 beams, described Bailey beam 4 is provided with distribution beam 5, and described distribution beam 5 is provided with steel platform panel 6.Described some sections steel casings 1 upper end flushes.Between described steel casing 1 side and lower floor's girder 3, be provided with bracket diagonal brace 2.
Construction method of the present utility model: (1), will steel casing be transported to job site after some sections processing in 1 minute; (2), on massif precipice, pile foundation is carried out to setting-out, take stake position is greater than some holes of steel casing diameter as center of circle digging diameter, then lift first sections steel casing, first sections steel casing is embedded in behind a hole, between steel casing outside and stake hole, concreting is fixed first section of steel casing; (3), lift all the other sections steel casings, be embedded in each Kong Zhongzhi upper end and first sections steel casing with high, after having buried underground, between steel casing outside and a hole, concreting is fixed all the other sections steel casings; (4), lower floor's girder 3 is installed on steel casing 1, in steel casing 1 side, bracket diagonal brace 2 is being installed; (5), Bailey beam 4 is installed on lower floor's girder 3; (6), distribution beam 5 is installed in Bailey beam 4, distribution beam 5 comprises transverse distribution beam 5.1 and longitudinal distribution beam 5.2; (7), in distribution beam 5, lay steel platform panel 6 and form steel platform construction district 8; (8), toward building pile foundation concrete in steel casing 1, form mixed earth post 10, steel casing 1 is as the main force structure that exposes pile foundation formwork and formwork supports steel platform panel 6; (9), on steel platform panel 6, build cushion cap 9 concrete, steel platform panel 6 is as cushion cap 9 bed dies, steel casing 1 and pile foundation are as the main force structure that supports cushion cap 9 overhanging portions and steel platform panel 6.
First the utility model is that rock stratum is extremely stablized in the stake hole (steel casing diameter is greater than design stake footpath 20cm) that excavation is greater than steel casing diameter 1m, steel casing has just been embedded in above stable rock stratum like this, then between steel casing outside and stake hole, builds the fixedly concrete of use steel casing is fixed.After steel casing fixedly completes, continue to carry out borehole construction operation in steel casing, between stake hole, press a design stake footpath borehole.After having set up, steel platform construction district starts to carry out pile foundation, bearing platform construction.
The utility model steel platform construction district adopts steel casing as basis, and bracket diagonal brace is installed on steel casing, lays Bailey beam and distribution beam, then in distribution beam, lay steel platform panel on bracket diagonal brace; During pile foundation construction, steel casing is as the main force structure that exposes pile foundation formwork and formwork supports steel platform panel; During bearing platform construction, steel platform panel is as cushion cap bed die, and steel casing and pile foundation are as the main force structure that supports cushion cap overhanging portion and steel platform panel.
The content that this manual is not described in detail belongs to the known prior art of professional and technical personnel in the field.
