[embodiment]
Below in conjunction with accompanying drawing, specific embodiments of the invention are done a detailed elaboration.
The underground works waterproofing of movement joints as shown in Figure 1, to have built dovetail groove in movement joint one side, one wing of built-in waterstop 7 is bonding to be anchored in the movement joint one concrete dovetail groove of side, another wing is cast in the concrete of opposite side, built-in waterstop 7 is fixed on movement joint both sides, realizes the waterproof of movement joint with this.
The on-the-spot hydraulic test method of building deformation joint waterproof system of the present invention as Fig. 1, comprises step:
Length cutting anchoring type according to movement joint pastes waterstop 4 outward, and the length of movement joint is different, and it is also different that the anchoring type that needs pastes the size of waterstop 4 outward; The both wings that paste waterstop 4 outside this anchoring type are respectively equipped with anchorage portion 5 (lateral dimension in this anchorage portion 5 cross sections pastes the lateral dimension in waterstop 5 cross sections, middle part outside greater than anchoring type); And paste outside anchoring type two pipe adapters are installed on waterstop 4, this pipe adapter is positioned at anchoring type and pastes waterstop 4 middle parts outward, do not hinder bonding anchoring type to paste waterstop 4 outward, when these two pipe adapters paste waterstop 4 and are bonded in the movement joint both sides outside anchoring type, can lead to the movement joint inner chamber;
The concrete of both sides, movement joint top is when building, preset respectively a groove 6, inject bonding agent (can be epoxy adhesive) in this groove, the anchorage portion 5 that anchoring type is pasted waterstop 4 both wings outward is placed in respectively in this groove, being about to one of them anchorage portion is placed in the groove of movement joint one side, the another one anchorage portion is placed in the groove of movement joint opposite side, thereby the both wings that this anchoring type pastes waterstop 4 outward are bonded in movement joint top, and the other both wings that anchoring type pastes waterstop 4 are outward docked with bonding agent, form airtight water proof ring;
After bonding anchoring type external labeling type waterstop 4, paste outside anchoring type and cover foam soft board and fiberboard above waterstop 4, temporary fixed with nailing;
After to be bonded dose of primary solidification, remove foam soft board and fiberboard, nailing; After removing, this moment can the visual examination bonding quality, in case bonding leak occurs;
Paste outside anchoring type and spread polyethylene polypropylene fiber sheet separation layer 3 above waterstop 4 to paste waterstop 4 outside the protection anchoring type, steel plate protective seam 2 is installed on the concrete of movement joint both sides afterwards, and this steel plate protective seam 2 is pressed on polyethylene polypropylene fiber sheet separation layer 3 and pastes waterstop 4 outward with the protection anchoring type;
Open respectively two pipe adapters, by the water filling in the movement joint of one of them pipe adapter, the exhaust of another one pipe adapter; Can carry out maintenance a period of time to pasting waterstop 4 outside bonding anchoring type before water filling in movement joint, to improve bonding strength, such as 7 days;
After having annotated water, the pipe adapter of sealing exhaust, system carries out the hydraulic testing to waterproofing of movement joints.This hydraulic testing program can determine by engineering design side, can be after immersion a period of time again the waterproofing of movement joints system be carried out the hydraulic testing, such as 24 hours.
This shows, the present invention can carry out the on-the-spot hydraulic testing to existing waterproofing of movement joints system, improves the waterproof reliability; And simple in structure, cost is low; After the hydraulic testing was complete, the anchoring type of installation pasted waterstop and steel plate protective seam etc. outward and all needn't remove, and has also set up waterproof measure one for movement joint, has improved further the reliability of waterproofing of movement joints in addition.
In one embodiment, the docking site of other both wings of pasting waterstop 4 outside with anchoring type to after catching, also comprises step with bonding agent: at the bonding PVC coiled material of the lateral surface of docking site with the reinforcement seam.
Wherein, described steel plate protective seam can be installed in segmentation, as Fig. 1, it comprises first paragraph steel plate and second segment steel plate, when mounted, first the first end with the first paragraph steel plate is fixed on the concrete of movement joint one side with foot bolt, then the first end of second segment steel plate is fixed on foot bolt on the concrete of movement joint opposite side, and the second side pressure of this second segment steel plate is on the second end of first paragraph steel plate; Steel plate below namely first installing, then the steel plate above installing.Make the steel plate protective seam of installation can follow the xoncrete structure dilatation.
In addition, in the specific implementation, as Fig. 2,3, described pipe adapter comprises base 11, set nut 12 and dome nut 13;
Need to prove, pipe adapter pastes on waterstop 4 except can being arranged on sticking anchor formula, also can be embedded in concrete when building after spreading, pipe periphery encapsulant and concrete bonding, the mouth of pipe leads to built-in waterstop 7 and sticking anchor formula and pastes movement joint inner chamber between waterstop 4 outward, the bonding reactive rubber of the wet paving of circle in steel pipe middle part, with concrete bonding, the pipe root of steel pipe exposed parts is preset dead slot, after concrete curing a period of time (such as 7 days), fill out epoxide-resin glue, prevent the clearance leakage between steel pipe and concrete.During with built-in pipe exhaust, water filling, the tube head hitch that built-in pipe exposes connects nipple, after water filling, exhausr port is tightened with plug; The water filling port mounted valve is connected with the pressure testing water pump.After the hydraulic testing, take off the valve of water filling port, change the plug sealing.
