Abstract
The invention belongs to the technical field of architectural design and construction, and particularly relates to a design and construction method of joining a new subway station and an existing subway station by holing baseplates. The design and construction method of joining the new subway station and the existing subway station by holing the baseplates sequentiallycomprises the following steps of: step one,performing holing construction on platform plates of the existing station; step two,performing holing construction on baseplates of the existing station; step three,constructing U-shaped stiffening beams, wherein the baseplates of the existing station are located in depressions of the stiffening beams; and step four,constructing transfer passageways, wherein the U-shaped stiffening beams are connected to the transfer passageways. According to the design and construction method, a shallow buried covered excavation method is mainly adopted for constructing new transfer passageways, top plates of the passageways pass through the middles of the structural baseplates of the existing subway station closely and downwards, then the existing baseplates are holed for realizing the transfer function, and the construction can be performed on the basis of minimumrenovationof the structure and equipment of the existing subway station. The construction method does not affect the normal operation of existing lines.
Description
Technical field
The invention belongs to architectural design and technical field of construction, particularly relate to a kind of new subway station and old subway station base plate and to punch the design and construction method be connected.
Background technology
Subway station is a kind of important building in Urban Rail Transit, auxiliary equipment comprises escalator, goes straight up to elevator, rolling door, the anti-Hongmen Gate, traveler guiding, throw light on, sell check system, station equipment robot control system(RCS) etc., for passenger's boarding, the place of changing to and waiting.At present due to a lot of existing line subway station, to build up the age comparatively remote, not reserved transfer interface condition at a specified future date, and scale is generally smaller, such as Beijing Metro 1, No. 2 lines, built up last century 60, the seventies, being all the form of one deck half, is individual layer section station layer namely, both sides are little interlayers, as station hall layer and device rooms district.Along with the fast development in city, after subway line net is formed, the key that needs solve is the transfer problem of new and old subway line.
Existing operating line passenger flow is saturated on the other hand, pressure is very large, if it is very unrealistic that transferring passage new-old structure connection is carried out in the stoppage in transit of consideration existing line, adding subway station generally builds at bustling block or major urban arterial highway, both sides high buildings and large mansions stand in great numbers, traffic above-ground is busy, and underground gathers pipeline, does not possess open cut condition.So transferring passage adopts shallow burial hidden digging to realize often, therefore newly-built transferring passage can not affect the normal operation of existing line, minimum to existing equipment transformation amount, realizes transfer function again, difficulty and risk are quite large, and this is all a very stern challenge to design and construction.
Summary of the invention
The invention provides a kind of new subway station and old subway station base plate to punch the design and construction method be connected, with solve in the transferring passage work progress that proposes in above-mentioned background technology on existing Metro Station Structure and scrap build little and do not affect the problem of existing line normal operation.
Technical problem solved by the invention realizes by the following technical solutions: a kind of new subway station and old subway station base plate punch the design and construction method be connected, and it is characterized in that: comprise the following steps successively:
The first step, to punch construction to building up station platform slab;
Second step, to punch construction to building up station base plate;
3rd step, builds U-shaped stiffening girder, and the base plate of building up station is positioned at the recess of U-shaped stiffening girder;
4th step, build transferring passage, U-shaped stiffening girder is connected with transferring passage.
Abolishing of building up station platform slab, base plate adopts diamond rope saw static force ablation technique, and cutting speed is fast, and the light and handy spirit of cutting machine becomes, the environment pollutions such as shockproof, noise, dust.Large area cutting is avoided to impact existing structure and operation security.
By U-shaped beam strengthening measure, avoid bar planting to damage both wired bottom girders, ensure both wired waterproof slab effects.
Wearing both wired and existing base plates under transferring passage punches in work progress, hydrostatic level is adopted to carry out 24 hours remote automation Real-Time Monitorings to existing structure and track, and monitored data is analyzed in time, design and construction, ensure safety and the normal operation of existing structure.
U-shaped stiffening girder is collar tie beam.
Beneficial effect of the present invention is:
This construction method mainly adopts the newly-built transferring passage of shallow burial hidden digging, through in the middle of existing Metro Station Structure base plate under passage top board is closely connected, then punch at existing base plate, realize transfer function, construct in the basis that this form of construction work can show existing Metro Station Structure and equipment in as far as possible little transformation, and this construction method can not have influence on the normal operation of existing line, wherein both wired station base plate, abolishing of platform slab adopts diamond rope saw static force ablation technique, the advantage of this technology is that cutting speed is fast, the light and handy spirit of cutting machine becomes, shockproof, noise, the environment pollutions such as dust.Large area cutting is avoided to impact existing structure and operation security, by U-shaped beam strengthening measure, bar planting is avoided to damage both wired bottom girders, ensure both wired waterproof slab effects, wearing both wired and existing base plates under transferring passage punches in work progress, hydrostatic level is adopted to carry out 24 hours remote automation Real-Time Monitorings to existing structure and track, and monitored data is analyzed in time, design and construction, ensure safety and the normal operation of existing structure, be connected to existing base plate by transferring passage and punch and be connected to both wired station layers, achieve " Room ~ platform " or " platform ~ platform " transfer easily, substantially reduce transfer distance and the transfer discrepancy in elevation, fully demonstrate the design concept that people-oriented, for Metro transfer stop provides good case history from now on, achieve good Social and economic benef@.

Detailed description of the invention
Be below the optional embodiment of the present invention, the technician in this professional domain can modify to it and polish under the prerequisite not changing the present invention's spirit and content.Below in conjunction with accompanying drawing, the present invention is described further:
New subway station and old subway station base plate punch the design and construction method be connected, and it is characterized in that: comprise the following steps successively:
The first step, to punch construction to building up station platform slab;
Second step, to punch construction to building up station base plate;
3rd step, builds U-shaped stiffening girder, and the base plate of building up station is positioned at the recess of U-shaped stiffening girder;
4th step, build transferring passage, U-shaped stiffening girder is connected with transferring passage.
