Description

The special-purpose build-up type track foundation of transfer crane

Technical field

The utility model relates to a kind of track of shield-tunneling construction, particularly relates to the special-purpose build-up type track foundation of a kind of transfer crane.

Background technology

Transfer crane is a kind of conventional auxiliary facility of current earth pressure balanced shield, EPBS construction, an important supplement as earth pressure balanced shield, EPBS construction, transfer crane is the important preparation of construction of vertical transport between tunnel and ground in work progress, is widely used in shield tunnel civil engineering.Transfer crane is compared with equipment such as tower crane, crane in bridge type, and the load-carrying ability of transfer crane is large, can be under the situation of load, and complete machine is walked along horizontal rail, and therefore, horizontal rail basis is also the necessary component of transfer crane.At present, track foundation mostly is cast-type reinforced concrete bed beam, construct cast-type reinforced concrete bed beam, first on-the-spot place all to be emptied, then carry out assembling reinforcement, installation form, built-in fitting is installed, the work such as casting concrete, also need the 28 day length of time of maintenance could load after concreting, finally on cast-type reinforced concrete bed beam, transfer crane is installed; Constructing tunnel finishes after hoisting crane dismounting, then removes grade beam.The shortcoming on this kind of cast-type reinforced concrete bed beam basis is long construction period; Restricted by place, can not construct in advance; Construction precision is low, and construction quality fluctuation is large; Basis can only disposablely be used, and also wants defrayment during dismounting.

Utility model content

The purpose of this utility model is to provide a kind of framing member by standard to constitute, simple and convenient assembly, and energy repeated usage, productive costs is low, can improve the operating efficiency of track foundation and the special-purpose build-up type track foundation of the transfer crane of construction precision of transfer crane.

The purpose of this utility model can realize.The special-purpose build-up type track foundation of transfer crane of the present utility model is characterised in that: the standard prefabricated components that include concreting in a special-purpose build-up type track foundation of transfer crane, the transversal surface of described standard prefabricated components is ' protruding ' font, axis direction along standard prefabricated components, on the bossing of standard prefabricated components, be embedded with as the crow flies the some groups of pre-embedded bolts of every two group, in the recessed part in both sides, be arranged with some groups of hangers, described standard prefabricated components become integral structure with described pre-embedded bolt and hanger, , described standard prefabricated components become integral structure with described pre-embedded bolt, described in each, on pre-embedded bolt, be all connected with a rail pressing plate, between two described pre-embedded bolts of same group, be equipped with rail, described rail by rail pressing plate, by pre-embedded bolt, be fixed on described standard prefabricated components bossing above, the common fixing rail track in alignment of pre-embedded bolt of described some groups, at least one standard prefabricated components, some groups of pre-embedded bolts, several rail pressing plates and a rail form a build-up type track foundation gauge member.

The special-purpose build-up type track foundation of the utility model transfer crane, wherein a special-purpose build-up type track foundation of described transfer crane is is longitudinally connected and composed by least two build-up type track foundation gauge members.

The special-purpose build-up type track foundation of the utility model transfer crane difference from prior art be the special-purpose build-up type track foundation of the utility model transfer crane adopt section be ' protruding ' font type, by concreting and be embedded with the standard prefabricated components of some pre-embedded bolts as the grade beam of shield construction track, standard prefabricated components are fixed a rail by some groups of pre-embedded bolts and rail pressing plate and are formed a build-up type track foundation part.Standard prefabricated components in the utility model are produced by member station-service Standard Module, have improved on the one hand structure precision, on the other hand can batch production, than field fabrication, saved template; Standard prefabricated components are produced in advance in factory, and maintenance in advance, is assembled into afterwards build-up type track foundation part again and dispatches from the factory, and quality is more stable; Build-up type track foundation part can break the whole up into parts, and according to tunnel construction site condition broken-up laying, has improved the alerting ability of construction; The weight control of standard prefabricated components is at 3～4t, and build-up type track foundation gauge member just can be laid by fork truck and small crane after being transported to scene, easy construction; Transfer crane can be installed after laying in basis at once, has shortened the duration, and after shield tunnel construction finishes, transfer crane dismounting is complete, and build-up type track foundation part can be entrucked and carried away at once, without going, removes the basis that traditional concrete cast-in-situ is lived again; Build-up type track foundation part can reuse, and saves construction material and resource.

Below in conjunction with accompanying drawing, the special-purpose build-up type track foundation of transfer crane of the present utility model is described further.
