The specific embodiment
Specifically describe job practices of the present invention below in conjunction with accompanying drawing, referring to Fig. 1, this figure is the sectional schematic diagram of the existing underground space, and wherein this underground space can be three layers a underground parking garage, as Gang Hui square, area, Xujiahui, Shanghai underground parking garage.Existing structure of this underground parking garage and size are: the B1 floor height can satisfy the needs of subway station station hall layer more than 4.2 meters; Top board and base plate thickness are bigger, and the top board and the base plate that need not to take other measure promptly to can be used as the station use; Post net spacing is bigger, can satisfy the gauge requirement of subway station through suitable replacement.Therefore, Gang Hui square underground parking garage is fit to be transformed into two layers of subway station, as shown in Figure 7.
Again as shown in Figure 1, existing underground parking garage comprises top board layer 1, B1 floor 2, underground two floor plates 3, base plate 4 and column 5.In transformation process, do not arrange system owing to do not change original structure, load is no change also, so keep former top board layer 1 as station top board layer.B1 floor 2 can be used as plate in the station, but because the design load of subway station is greater than general civilian construction, after transformation is finished, through original structure is checked, can post carbon fiber 21 ' this floor is reinforced this two kinds of ruggedized constructions such as Fig. 8 and shown in Figure 9 at these floor plate 2 upper surface concreting overlapping layerss 21 or at the beam slab soffit.
Because therefore nearly 6 meters of the station layer floor heights of general subway station can take to cut former underground two floor plates 3, this floor is hereinafter alleged quilt and cuts layer, so that former three layer construction is transformed into two-layer structure so that transform the requirement that the back floor height can meet the platform floor height.Be additional internal force and the distortion of avoiding producing in the process of cutting, should construct in order according to the principle of " symmetry, segmentation, balance ".Below in conjunction with accompanying drawing, describe the step that cuts of the present invention in detail.
Referring to Fig. 4, cut the plan view of layer 3 shown in the figure.At first, this floor delimited a plurality of rectangles excavation area at interval by equal proportion; Again as shown in Figure 5, with these rectangle excavation areas longitudinally span be divided into first excavation section 31 and second batch of excavation section 32, in the drawings, first excavation section 31 is shown in shade, second batch of excavation section 32 is shown in blank, simultaneously, each excavation section 31,32 again on horizontal span equal proportion be divided into three parts, i.e. the seat part segmentation 31a at two ends, 31a ', 32a, 32a ' and middle span centre section 31b, 32b.When cutting, at first cut first excavation section 31, promptly part shown in the shade wherein, cuts span centre section 31b earlier when cutting each section, and seat part segmentation 31a, the 31a ' with two ends cuts again.As shown in Figure 6, when first excavation section 31 is all cut (part shown in the figure empty), again second batch of excavation section 32 (part shown in the shade) all cut.Similarly, earlier span centre section 32b is cut when cutting each section, seat part segmentation 32a, the 32a ' with two ends cuts again.Through aforesaid cutting after the step, the garage structure that is about to former F3/B3 is transformed into two-layer structure.
Owing to cut after the former underground two floor plates 3, former column calculated length is increased greatly, supporting capacity also decreases, and therefore need be reinforced by column 5 before cutting underground two floor plates.Preferably, shown in Fig. 2 and 3, excessive for preventing to reinforce the rear column section, the present invention adopts steel structure body external reinforcement method, promptly coats angle steel 6 on 5 four ribs of existing column, and links to each other by the plate 7 that stops.
In job practices of the present invention, because the base plate 4 in garage adopts normal pile foundation support table under the original place, thickness is bigger, than one of as underground two layers of station base plate higher rigidity and durability are arranged, so kept with as the station base plate.
Through after the above-mentioned construction sequence of the present invention, former underground three-layer garage can be transformed into two layers of subway station as shown in Figure 7, and this station is an island station as shown in figure 11.Certainly, also can be as shown in figure 12 side formula station.
Preferable, no longer ad hoc end well in this improved station, but well is accepted as the shield structure in the end, station.As shown in figure 10, when the shield structure arrived former outer wall of basement 7, hole 71 was dug out in the corresponding section on exterior wall 7, to realize being connected of subway sectional tunnel and station.Consider the needs that reduce existing basement influence and practice of construction, after finishing being connected of running tunnel and station, shield shell 8 discarded in outside no longer take out within the walls, simultaneously steel hoop concrete portal circle 9 is set on the exterior wall hole, combines door with the station and form a running tunnel easily.
As can be known, adopt method of the present invention needn't carry out under the prerequisite of relocation of services and traffic organization from the description of above being done, " because of ground suits, construct in the part " just can utilize existing F3/B3 garage to build up underground two layers of subway station with less investment.
