Description
Technical Field
The utility model belongs to the technical field of hydraulic engineering, concretely relates to retaining wall movement joint prevention of seepage and stagnant water prosthetic devices.
Background
The existing retaining wall in hydraulic engineering needs to set deformation joints according to the standard requirements, and all parts with the deformation joints need to be provided with water stopping devices in order to prevent seepage; in the prior art, the water stop belt of the deformation joint is basically buried in a middle-buried mode, namely the water stop belt is buried in concrete structures on two sides of a settlement joint. However, in practical engineering, the deformation joint still often leaks, which indicates that the water stop is unreliable in water resistance, and the existing water stop cannot be repaired or replaced. Under the action of the differential settlement, once a water stopping device of a settlement joint is damaged, inclined holes are drilled and pressure grouting is carried out for stopping leakage, but the function of adjusting settlement of the settlement joint after plugging is lost, and the possibility of water leakage at the position still exists if uneven settlement continues to develop.
The retaining wall of the city river bank protection is also called flood control wall in Shanghai city. For example, the suzhou river flood prevention wall in Shanghai generally needs to be provided with a settlement joint, namely a permanent deformation joint, which is referred to as a deformation joint for short, every 10-15m, and the information shows that about 27000 deformation joints exist in the flood prevention walls on both sides, and the leakage repair is difficult after the deformation joints are damaged.
The deformation joint is preset in the flood prevention wall, which is an indispensable design content, and the water stopping is accompanied with the deformation joint. The deformation joint divides the flood control wall into independent sedimentation units, and damage caused by uneven sedimentation of the foundation can be effectively prevented. However, the settlement of the flood control walls on the two sides of the deformation joint or the deformation joint between the flood control wall and the bridge abutment is difficult to be uniform, so that water stopping damage is often caused, and under the action of water pressure, river water seeps into the wall along the vertical deformation joint. Water seepage through the deformation joint is generally indicated by water seepage at the position of a sidewalk or a curb behind a wall. In addition, there is also a case where there is no water seal at a seam. For example, the joint of the new wall and the old wall is usually a deformation joint, and the waterstop cannot be normally arranged because of non-simultaneous construction, so the joint is also a leakage prone part.
More complicated problems are that in the prior art, deformation joints of the flood control wall are leaked, the deformation joints cannot be maintained and replaced after water stop failure, high polymer grouting is often adopted for repair, and the joints cannot be completely plugged, so that the deformation joints are integrated and do not play a role in deformation, the significance of the deformation joints is lost, and hidden dangers are brought to engineering safety.
The situation shows that innovative technology is needed for seepage-proofing repair of deformation joints of retaining walls (flood control walls) in the current situation.
