Abstract
The invention discloses a method of layered and segmental construction, excavation and holing of transverse passages of a vertical shaft of a metro. According to the method, the height of setting up a scaffold is effectively reduced in a process of carrying out construction, excavation and holing of the transverse passages through a layered and segmental holing manner, so that the set-up work amount of the scaffold and the loss of the scaffold due to muck burying are reduced, and the security risk caused by the height of setting up can be reduced.
Description
Technical field
The present invention relates to a kind of method of excavating into hole, be specifically related to the layering of a kind of subway vertical shaft, segmentation turns adit construction and excavates the method into hole.
Background technology
Tradition multilayer accessory channel vertical shaft enters hole and adopts and set up scaffold after vertical shaft back cover and abolish, as shown in Figure 1, because multilayer accessory channel is conventionally highly higher, the scaffold of setting up is thereupon also higher, the scaffold of high height is not only set up and need to be expended a large amount of human and material resources, and the dregs that accessory channel when construction produces can bury scaffold bottom, cause a large amount of losses of scaffold, also can cause the vertical shaft inconvenience of slagging tap; Because scaffold height is higher, staff's security risk also can increase.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, provide the layering of a kind of subway vertical shaft, segmentation to turn adit construction and excavated the method into hole, the method adopts the mode of layering, segmentation to enter hole, can effectively reduce the height of scaffold, reduces the security risk of construction.
For achieving the above object, subway vertical shaft of the present invention layering, segmentation turn adit construction and excavate into the method in hole and comprise the following steps:
1) by To Construction of Silo to N rice under first floor transverse passage-way inverted arch, then lay the interim back cover of first floor in the bottom of vertical shaft, and on the interim back cover of first floor, set up the scaffold of first floor, carrying out the portal of first floor transverse passage-way abolishes and excavation construction again, and then the scaffold of dismounting first floor, the excavation that completes first floor transverse passage-way enters hole;
2) abolish the interim back cover of last layer, by To Construction of Silo to N rice under lower one deck transverse passage-way inverted arch, then the interim back cover of one deck under laying in the bottom of vertical shaft, and on the interim back cover of lower one deck, set up the scaffold of lower one deck, carrying out the portal of lower one deck transverse passage-way abolishes and excavation construction again, then the scaffold of removing lower one deck, the excavation that completes lower one deck transverse passage-way enters hole;
3) repeating step 2), the excavation that completes all transverse passage-ways except last one deck transverse passage-way enters hole, then abolish the interim back cover of layer second from the bottom, by N rice under extremely last To Construction of Silo one deck transverse passage-way inverted arch, then lay final back cover in the bottom of vertical shaft, and setting up the scaffold of last one deck on final back cover, then the portal that carries out last one deck transverse passage-way is abolished and excavation construction, then remove the scaffold of last one deck, complete all adit constructions and excavate into hole.
Step 1) in the time that the length of first floor adit construction supporting is greater than the diameter of first floor transverse passage-way of 3 times, remove the scaffold of first floor;
Step 2) in when the length of one deck adit construction supporting is greater than the diameter of lower one deck transverse passage-way of 3 times instantly, remove the scaffold of lower one deck;
Step 3) in the time that the length of last one deck adit construction supporting is greater than the diameter of last one deck transverse passage-way of 3 times, remove the scaffold of last one deck.
N >=in 2, and N≤3.
The present invention has following beneficial effect:
Subway vertical shaft of the present invention layering, segmentation turn adit construction and excavate into the method in hole carrying out in the process of adit construction, the interconnection of every one deck is excavated respectively into hole, simultaneously to excavating in the process in hole except other layer of later interconnection of last one deck, only need carry out interim back cover in the bottom of vertical shaft, then scaffolding erecting, thereby effectively shorten the height of scaffold, save the material of scaffold, reduce greatly constructor's security risk simultaneously, really accomplish safety construction.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
With reference to figure 2, Fig. 3, Fig. 4 and Fig. 5, subway vertical shaft of the present invention layering, segmentation turn adit construction and excavate into the method in hole and comprise the following steps:
1) vertical shaft 1 is constructed to N rice under first floor transverse passage-way 2 inverted arch, then lay the interim back cover 51 of first floor in the bottom of vertical shaft 1, and on the interim back cover 51 of first floor, set up the scaffold 41 of first floor, carrying out the portal of first floor transverse passage-way 2 abolishes and excavation construction again, and then the scaffold 41 of dismounting first floor, the excavation that completes first floor transverse passage-way 2 enters hole;
2) abolish the interim back cover of last layer, vertical shaft 1 is constructed to N rice under lower one deck transverse passage-way inverted arch, then the interim back cover 52 of one deck under laying in the bottom of vertical shaft 1, and on the interim back cover 52 of lower one deck, set up the scaffold 42 of lower one deck, carrying out the portal of lower one deck transverse passage-way abolishes and excavation construction again, then the scaffold 42 of removing lower one deck, the excavation that completes lower one deck transverse passage-way enters hole;
3) repeating step 2), the excavation that completes all transverse passage-ways except last one deck transverse passage-way 3 enters hole, then abolish the interim back cover of layer second from the bottom, vertical shaft 1 is constructed to N rice under last one deck transverse passage-way 3 inverted arch, then lay final back cover in the bottom of vertical shaft 1, and setting up the scaffold of last one deck on final back cover, then the portal that carries out last one deck transverse passage-way 3 is abolished and excavation construction, then remove the scaffold of last one deck, complete all adit constructions and excavate into hole.
