In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 4, the present invention's application said system realizes and to the non-migrating formula suspension protection method of pipeline to be: location colligation 100, suspention are built on stilts 101, building drilled pile 102, building stake are born responsibility platform 103, remove on suspension 104, nest of tubes, seal 105, cut stake 106, scheme completes 107.
To describe in detail respectively each step below.
Fig. 5 shows the former communication line location colligation of the present invention 100 schematic diagrames.
Step 100: determine and pass through behind original communication line 2 positions of planning to build on subway station deep basal pit 1 according to subway main body construction drawing, excavation conduit wiring suspension construction passage 3 (determining depending on nest of tubes width and length); Bottom the nest of tubes of original communication line 2, after two meters of punchings, identical posting 4 is installed and is positioned colligation.The quantity of posting 4 is determined by passing through the length of planning to build the original communication line 2 on subway station deep basal pit 1.
Fig. 6 shows the scheme of installation of posting 4 of the present invention.
Posting 4 of the present invention is that (two lead screw diameters are long by 4 two ends band strips, be convenient to adjust distance and colligation nest of tubes) angle steel of screw hole and 4 cover bolts form, it can be combined into square or rectangular, look the nest of tubes subject form of original communication line 2 and determine.
Fig. 7 shows built on stilts 101 schematic diagrames of the former communication line suspention of the present invention.
Step 101: complete after the location colligation 100 of original communication line 2, in the nest of tubes bottom of original communication line 2 every 3 meters of soil layers of planning to build subway station deep basal pit 1 that burrow and do not excavate with construction passage 3 both sides as the strong point, suspension 5 is installed, the whole original communication line 2 planned to build on subway station deep basal pit 1 that passes through is maked somebody a mere figurehead.
Fig. 8 shows former nest of tubes suspension 5 schematic diagrames of the present invention.
Suspension 5 of the present invention is comprised of the suspention pull bar (reinforcing bar) that contains thread with upper and lower suspention beam (channel-section steel) and the two ends of two screw holes (spacing is determined by the nest of tubes width of original communication line 2) respectively and nut, pad etc.
Fig. 9 shows the present invention and builds drilled pile 102 schematic diagrames.
Step 102: respectively build a drilled pile 6 in nest of tubes bottom in the nest of tubes both sides of original communication line 2, prepare the in-situ precast stake platform of bearing responsibility.
Figure 10,11 shows in-situ precast drilled pile of the present invention platform 103 schematic diagrames of bearing responsibility.
Step 103: first excavate the basis of nest of tubes two ends temporary supporting wall 7 and bottom and soil layer in appropriate depth, make the stake platform cast-in-situ template of bearing responsibility, the cast-in-situ steel reinforced concrete stake platform of bearing responsibility, completes the support to original communication line 2.
The reinforced concrete pile of the present invention platform of bearing responsibility is bipartite cross brace summer.A part is two brace summers 8 between top, and another part is the groove type brace summer 9 of original communication line 2 nest of tubes bottoms.The groove depth of groove type brace summer 9 be more than 150mm or original communication line 2 nest of tubes bottom 150mm, nest of tubes height is with interior all sizes, depending on concrete condition, determine.
Armored concrete groove type brace summer 9 of the present invention is when cast-in-situ steel reinforced concrete, lower suspention beam (channel-section steel) in posting 4, suspension 5 and bottom suspention pull bar (reinforcing bar) and nut, pad etc. are all embedded in armored concrete, can not be removed.
Figure 12,13 shows the present invention and removes suspension 104 schematic diagrames.
Step 104: removing suspension 104 is could remove after platform 103 stands under load are born responsibility in stake, it is only removed the upper suspention beam (channel-section steel) of suspension 5 and exceeds more than original communication line 2 nest of tubes top 150mm suspention pull bar (reinforcing bar) and nut, pad etc.
Figure 14,15 shows and on nest of tubes of the present invention, seals 105 schematic diagrames.
Step 105: carry out sealing 10 on armored concrete after sealing cast-in-situ template on making nest of tubes.
On nest of tubes of the present invention, seal in 105, the groove type brace summer 9 groove mouths (upward) of sealing 10 groove mouth down and original communication line 2 nest of tubes bottoms on armored concrete agree with and build in one.
Now, the present invention plans to build subway station deep basal pit 1 original communication line 2 to passing through carries out suspension protection scheme to be completed substantially, can carry out excavation and the corresponding construction operation of subway station deep basal pit 1.
Figure 16,17 shows the present invention and cuts stake 106 schematic diagrames.
Step 106: when the diaphram wall 11 in subway station deep basal pit 1 and body supports beam 12 are built complete and loadable, utilize construction method and the technique of cutting stake 13 of Pile Underpinning Technology, by lower boreholes stake 6 amputation of body supports beam 12.
When subway station diaphram wall 11 of the present invention and body supports beam 12 built complete and loadable, bear responsibility groove type brace summer 9 two ends of the original communication line 2 nest of tubes bottoms in platform of stake are supported and are converted into subway station diaphram wall 11 and support by temporary supporting wall 7; The stake platform 103 of bearing responsibility is supported to transform by subway station body supports beam 12 by drilled pile 6 and supports.
Of the present invention the platform of bearing responsibility supported to transform by subway body supports beam 12 by drilled pile 6 and supports, and is when building subway body supports beam 12,, in drilled pile 6 and subway body supports Liang12 intersection, both reinforcing bars be welded and built in one.
Figure 18,19 shows the present invention program and completes 107 schematic diagrames.
This figure is the end result of the preferred embodiment of technical solution of the present invention, it implement to pass through on the nest of tubes of original communication line 2 of planning to build subway station deep basal pit 1, seal 10 and loadable after, can construct to subway station deep basal pit 1.After implementing section stake 13, whole scheme completes, can be to Implement Construction in whole subway station.
On the nest of tubes of original communication line 2 of the present invention, seal in 10, the cable in pipeline is not done any moving and is changed, and keeps original state and is subject in the protection of the nest of tubes of original communication line 2.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
