Abstract
The invention relates to a construction method for origination of shield machine, comprising following procedures that a steel sleeve with the thickness suitable for the cutter disc thickness of shield machine is set at the back of originating portal; before shield origination, rubber water-stop curtain and pressing plate are set at the tail of assembled steel sleeve; when the shield machine is launched and the shield machine enters into the steel sleeve from bracket, the cutter disc of shield machine stops rotating and the shield machine moves forwards; when the head of shield machine enters into the steel sleeve through the rubber water-stop curtain and the cutter tip is against the protective structure, the shield machine stops moving forward temporarily. In the invention the method that the shield machine cuts the portal directly is adopted to dig and a steel sleeve with the thickness suitable for the cutter disc thickness of shield machine is set at the back of originating portal; the position of rubber water-stop curtain is moved to the end of steel sleeve form the portal position and the length of steel sleeve is used to add the distance between cutter disc and rubber water-stop curtain so that incision water pressure is built at the time of shield machine origination at the earliest time; finally the purpose of invention is achieved.
Description
Technical field
The present invention relates to the realm of building construction, particularly relate to the job practices of the shield launching in the constructing tunnel.
Background technology
In engineering in the past, the method of shield launching all is to adopt earlier the stratum, termination to be reinforced, before shield launching, after the concrete of space enclosing structure in the portal scope, reinforcing bar etc. cut, shield machine just can start, and just can finish the general time of needs about 15 days of cutting of portal.For cooperating overall Construction Plan, when space enclosing structure is constructed, the shield machine material that can directly cut that in left tunnel line portal scope, used (pre-buried in space enclosing structure), during the left line shield launching of this engineering, need not portal is cut, directly the cutting driving can reduce the risk and the saving duration that cut portal.
Summary of the invention
The object of the present invention is to provide a kind of efficient, succinct, shield launching mode of saving the duration, also greatly reduce simultaneously portal is cut existing risk, set up otch hydraulic pressure when making shield launching as early as possible, for controlling ground settlement preferably provides the job practices of the shield launching of effective guarantee.
The objective of the invention is to be achieved through the following technical solutions:
(1), behind the portal that starts, sets up the long steel bushing that adapts with cutter head of shield machine thickness of 500-1000mm, wherein, described steel bushing by more than at least 2, the steel plate workpiece processing of circular arc that about 30-50mm is thick is assembled, adopt bolt to connect between workpiece, each parts adds the weldering ribs with angle steel or steel pipe to be fixed, and prevents to be out of shape in dismounting and the transportation;
(2) make up after the workpiece for the treatment of steel bushing machines, locate to steel bushing, be connected with bolt after between steel bushing and former portal, adding δ=3mm rubber rubber cushion, and fill space between steel bushing bottom and the base plate, to prevent making its distortion after shield machine from entering steel bushing with plain concrete;
(3) before the shield launching, at the end of mounted steel bushing, install the rubber sealing door curtain made of cloth and pressing plate successively earlier;
(4) when shield launching, when shield machine began to enter steel bushing from carriage, the cutterhead of shield machine stopped operating, just shield machine is pushed ahead, treat that the shield machine head enters steel bushing by the rubber sealing door curtain made of cloth, and after its point of a knife withstood space enclosing structure, shield machine halted temporarily;
(5) circulation system of startup shield machine makes its shield machine reach mud and water balance, and rotating cutter-head, the space enclosing structure in the portal scope is directly cut shield launching.
The present invention is owing to adopted shield machine that the method (sew worker's method) that portal directly cuts is tunneled, but owing to need not to cut portal, make the distance between the cutter head of shield machine and the rubber sealing door curtain made of cloth shorten greatly, for the destruction that prevents that cutterhead from producing the door curtain made of cloth when rotating, the present invention adopts and set up a steel bushing that adapts with cutter head of shield machine thickness behind the portal that starts, and the position of the rubber sealing door curtain made of cloth moved to the steel bushing end from portal, utilize the length of steel bushing to increase distance between the cutterhead and the rubber sealing door curtain made of cloth, and set up otch hydraulic pressure as early as possible when making shield launching, reach purpose of the present invention.
Describe realization of the present invention in detail below in conjunction with accompanying drawing:
Description of drawings
Fig. 1 is a constructing structure schematic diagram of the present invention;
Fig. 2 is that the structure of steel bushing of the present invention is formed schematic diagram;
The specific embodiment
As Fig. 1～shown in Figure 2, the job practices of shield launching of the present invention may further comprise the steps:
(1), setting up a 500-1000mm length behind the portal that starts (specifically decides on the thickness of cutterhead, generally be slightly larger than cutterhead thickness,) steel bushing as shown in Figure 21, wherein, described steel bushing 1 by more than at least 2, the steel plate workpiece processing of circular arc that about 30-50mm is thick is assembled, adopt bolt to connect between workpiece, it is fixing that each parts adds weldering ribs 1 with angle steel or steel pipe, prevents to be out of shape in dismounting and the transportation;
(2) make up after the workpiece for the treatment of steel bushing 1 machines, give steel bushing 1 location, be connected with bolt after between steel bushing 1 and former portal, adding δ=3mm rubber rubber cushion, and fill space between steel bushing bottom and the base plate, to prevent making its distortion after shield machine from entering steel bushing with plain concrete;
(3) before the shield launching, at the end of mounted steel bushing 1, at first install the rubber sealing door curtain made of cloth 3 earlier, and then pressing plate 2 is installed, to compress the door curtain made of cloth 3 along periphery.Steel bushing 1, the rubber sealing door curtain made of cloth 3 and pressing plate 2 threes link together by bolt;
(4) when shield launching, when shield machine began to enter steel bushing 1 from carriage, the cutterhead of shield machine stopped operating, just shield machine is pushed ahead, treat that the shield machine head enters steel bushing 1 by the rubber sealing door curtain made of cloth 3, and after its point of a knife withstood space enclosing structure, shield machine halted temporarily;
(5) circulation system of startup shield machine makes its shield machine reach mud and water balance, and rotating cutter-head, the space enclosing structure in the portal scope is directly cut shield launching.
Claims (1)
1, a kind of job practices of shield launching is characterized in that may further comprise the steps:
