Description

Temporary pavement bedding structure and job practices for super shallow buried covered excavation underground construction
Technical field
The present invention relates to a kind of temporary pavement bedding structure of constructing on urban road surfaces that is laid on, relate in particular to a kind of bedding of the temporary pavement for super shallow buried covered excavation underground construction structure and job practices.
Background technology
In the construction of shallow buried covered excavation underground construction underway, the normal method of advance support and preliminary bracing that adopts is reinforced the country rock of underground construction, especially the top country rock, make it keep stable and not produce excessive distortion, can bear the effect of top soil body weight and road vehicles load.But, adverse effect due to factors such as Rock Conditions are poor, thickness of earth covering is thin, underground utilities are many, advance support and preliminary bracing can not effectively be implemented, or the effect that still is not enough to resist upper formation and load of the stratum supporting capacity through reinforcing, cause road surface to subside, jeopardize traffic safety, even bring life and property loss.At present, for underground engineering with shallow, 10~20mm steel plate is laid as ancillary method in the ground of being everlasting.But, because thickness is limited, bending rigidity is little, the effect that diffusion reduces load is limited, according to the material mechanics principle analysis, increases merely producing little effect that steel plate thickness obtains.Vertical motion, under Vehicle Load, occurs in steel plate in addition, can increase vertical dynamic loading on the contrary; Steel plate is subject to the repeated action of horizontal force in Vehicle Driving Cycle or braking procedure, and longitudinal leap occurs.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, convenient and quick construction, little to the ground traffic impact, underground engineering off-load is made to the bedding of the temporary pavement for super shallow buried covered excavation underground construction structure and the job practices made good use of.By adopting temporary pavement bedding structure, adopt the shaped steel combination structure, increase considerably the bending rigidity of bedding structure, in bedding structure both sides, ramp is set simultaneously, guarantee that road vehicles travels with certain speed-limiting safety, reduce vehicular load directly to the effect of top of underground country rock.
The technical solution used in the present invention is as follows:
A kind of bedding of the temporary pavement for super shallow buried covered excavation underground construction structure, it is characterized in that: above the shallow buried covered excavation underground construction, road surface is provided with temporary pavement bedding structure, its laying scope is advisable with the scope that can cover Underground Construction and may have influence on along the road longitudinal length, laterally can cover all motorways.Temporary construction road surface bedding structure comprises main bedding structure, rubber pad, ramp bedding structure, back-pressure steel plate pavement structure and railway spike; Described main bedding structure consists of some main bedding construction standard external member welding, described main bedding construction standard external member consists of some bottoms lacing plate, some middle parts i iron and a top printed steel plate welding, top printed steel plate, bottom lacing plate and middle part i iron directly weld, every two bottom lacing plate interval 0.5m~1.0m distances, thus the workman is spaced during this time from top steel plate and middle part i iron being welded.Form main bedding structure along bridge to adopting vertical elongated reinforcing bar to weld between the main bedding construction standard external member be arranged side by side, main bedding structure two ends are provided with ramp bedding structure, and the direction across bridge between main bedding structure and ramp bedding structure adopts horizontal elongated reinforcing bar welding, to the diameter of elongated reinforcing bar, according to the thickness of top steel plate, selects in length and breadth, to guarantee that paving is smooth-going, is advisable, described ramp bedding structure consists of some ramp bedding construction standard external member welding, described ramp bedding construction standard external member is by bottom lacing plate, the oblique And of Varying Depth i iron in middle part and the welding of top printed steel plate form, bottom lacing plate, the welding manner of the oblique And of Varying Depth i iron in middle part and top printed steel plate is identical with the welding manner of main bedding construction standard external member, the oblique And of Varying Depth i iron in middle part is to adopt the complete oblique cutting of i iron to form, form ramp bedding structure along bridge to adopting vertical elongated reinforcing bar to weld between the ramp bedding construction standard external member be arranged side by side, completely be covered with the thick rubber pad of 10~15mm below main bedding structure and sloped sides road bedding structure, as construction temporary pavement bedding structure continuous elastic basis, be provided with back-pressure steel plate pavement structure in the crossing position of ramp bedding structure and road surface, both sides, back-pressure steel plate one end in back-pressure steel plate pavement structure is connected on ramp bedding structure by horizontal elongated steel bar welding, the other end is connected and fixed by railway spike and road surface, and railway spike is fixed on the back-pressure steel plate on road surface by the rear mode of implanting anchoring of punching on road surface.
