Description

Intermittent type filling device for remedying sleeve grouting defects

Technical Field

The utility model relates to a prefabricated assembly type structure technical field, concretely relates to intermittent type nature mend irrigation device for remedying sleeve grout defect.

Background

In recent years, the detection technology of the grouting fullness of the sleeve has made a substantial breakthrough, and a plurality of mature detection methods have been brought into national industry standards or relevant local standards. However, the detection of the grouting fullness of the sleeve is only 'recognition of diseases', and how to 'treat diseases' after problems are found is a technical problem at present, and related researches are few. Along with the popularization and development of the sleeve grouting fullness detection work, the industry pays more attention to the grouting defect treatment problem, and the grouting defect treatment method is urgently expected to solve the problem.

The utility model discloses a utility model patent of CN215717299U "a device that sleeve grout defect haplopore mends and irritates", when being directed at through grout outlet hole haplopore mend and irritated, the inside air of sleeve can't in time be discharged, cause the condition of nest gas phenomenon, propose to fill in grout outlet hole with slip casting pipe and kinescope of being connected with the exhaust tube simultaneously, and adopt flexible seal material to seal the grout outlet, utilize electronic push-pull to drive the exhaust tube and bleed and with slip casting section of thick bamboo slip casting, thereby the inside air of discharge sleeve, eliminate nest gas phenomenon, reach anticipated grout filling effect. When the device is used, the capacity of the air pumping cylinder can be larger than that of the grouting cylinder, the electric push-pull device drives the air pumping cylinder to start pumping air firstly and then drives the grouting cylinder to perform grouting simultaneously, and the purpose is to enable the inside of the sleeve to form negative pressure firstly so as to achieve a better grouting effect.

When single-hole filling is carried out from the grout outlet, the grouting material flows downwards along the gap between the inner wall of the sleeve and the connecting reinforcing steel bars under the action of self weight. Because the grouting material has certain viscosity, and the inner wall of the sleeve and the surface of the connecting reinforcing steel bar are always attached with the residual grouting material in the first grouting process, the downward flowing speed of the grouting material is slowed down in the grout supplementing process. If continuous slurry replenishing is adopted, the slurry sometimes flows back up due to the fact that the slurry cannot flow down in time, so that field construction personnel can mistakenly think that the replenishing is full, and the slurry replenishing is finished in advance. For such situations, intermittent grout replenishment can be attempted, i.e. grouting and suspension are performed at intervals, in order to allow sufficient time for grout that has been replenished into the sleeve to flow downwards. However, in practice, it is found that, because the negative pressure is adopted for replenishing the slurry and the inside of the sleeve is negative pressure, the slurry in the grouting barrel can be continuously sucked into the inner cavity of the sleeve during the pause process, and the sucking speed is slightly slower than the active grouting speed. In this case, the slurry back-flushing phenomenon may still occur, and the success rate of slurry replenishment may be affected.
