Abstract
The utility model provides an expanded rubber plug for a reserved grouting pore channel grouting leak repairing construction method. A grouting connector pipe is communicated in a hollow screw rod and is fixedly connected with the hollow screw rod which is provided with a screw rod nut which is in threaded connection with the hollow screw rod. Spanner rods are symmetrically arranged on two sides of the screw rod nut. The grouting connector pipe is provided with a rubber sleeve in a sleeved mode. Blocking rings are respectively arranged on the upper end face and the lower end face of the rubber sleeve. A pressing sleeve of the hollow screw rod is connected between the upper blocking ring and the screw rod nut in a sleeved mode. The lower blocking ring is supported on a pipe clamp which is connected with the grouting connector pipe in a threaded mode. According to the expanded rubber plug, a nut screw rod structure and the rubber sleeve are arranged on the grouting connector pipe, the screw rod nut is screwed down through the spanner rod, the rubber sleeve is deformed through the pressing sleeve, one end of the rubber sleeve is support on the pipe clamp and on the lower blocking ring, and the deformed rubber sleeve not only achieves strong blocking of an end opening of a reserved grouting pore channel but also fixes the grouting connector pipe. The expanded rubber plug has the prominent advantages of being simple and reasonable in structure and convenient to use.
Description
Technical field
The utility model belongs to water seepage-proof tech, particularly relates to a kind of expansion plug for reserving slip casting duct slip casting mending-leakage job practices.
Background technology
Reserving the slip casting duct is a kind of effective job practices of ground-connecting-wall joint close slip casting mending-leakage, is 5～10Mpa by the pressure limit of reserving slip casting duct slip casting.
Its port should also must provide the mouthpiece that is connected with the grouting pump delivery hose in powerful shutoff to the slip casting of reservation slip casting duct the time.
Summary of the invention
The purpose of this utility model provides a kind of expansion plug for reserving slip casting duct slip casting mending-leakage job practices.
The utility model is taked following technical scheme for achieving the above object: a slip casting mouthpiece runs through hollow lead screw and is fixedly connected with it, hollow lead screw is provided with the feed screw nut that is threaded with it, described feed screw nut bilateral symmetry is provided with wrenching bar, described slip casting mouthpiece is set with rubber sleeve, the rubber sleeve upper and lower end face is respectively equipped with back-up ring, be provided with the gland that is socketed on hollow lead screw between described upper back-up ring and the feed screw nut, described lower back-up ring is supported on the pipe collar that is threadedly connected to the slip casting mouthpiece.
The utility model can also be taked following technical measures:
Be provided with the interval between the cell walls in described up and down back-up ring edge and reservation slip casting duct.
The beneficial effects of the utility model and advantage are: this expansion plug arranges nut screw structure and rubber sleeve at the slip casting mouthpiece, make the feed screw nut backspin by wrenching bar, make an end be supported in the rubber sleeve distortion of pipe collar and lower back-up ring by gland, the rubber sleeve of distortion has not only been realized simultaneously the slip casting mouthpiece being fixed to the powerful shutoff of reserving slip casting duct port.The utlity model has outstanding advantages simple and reasonable, easy to use.
