Problems solved by technology

Whether it can be used here is mainly controlled by the terrain, if the terrain conditions do not allow it, it cannot be used
[0008] In addition, the dynamic change of the groundwater level of the bank slope caused by the rise and fall of the reservoir water level is also a problem worthy of attention. The dynamic change of the groundwater level not only deteriorates the strength of the rock and soil mass of the bank slope, but also the seepage of groundwater to the outside of the slope may directly lead to the slope unstable
[0009] In view of this, in view of the fact that the outer slope of the bridge pile foundation in the valley slope of the reservoir is prone to local instability due to changes in the reservoir water level, which affects the safety of the bridge pile foundation, it is urgent to develop a suitable for large-scale reservoirs. Engineering Technology of Bridge Pile Foundation Protection

Embodiment 1

[0039] This embodiment discloses a wall-mounted drainage anchor retaining wall structure to solve the problems existing in the protection technology of bridge pile foundations in the banks and valleys of the drawdown zone of large reservoirs. see figure 1 , the retaining wall structure includes a longitudinal beam 4 embedded in the top of the bank slope, as well as a retaining wall 1 and an anchor rod 2 .

[0040] The retaining wall 1 is arranged on the water side of the bank slope. The retaining wall 1 includes a retaining wall body 101 . The two ends of the retaining wall body 101 along the direction of the bank slope extend a receiving portion 102 into the rock and soil body behind the wall. The function of the retaining wall 1 is to support the rock and soil mass behind the retaining wall and to seal the surface of the rock and soil mass. When the length of the retaining wall is too long, deformation joints can be provided in the retaining wall 1, and water-stop materia...

Embodiment 2

[0045] This embodiment provides a construction method for the wall-mounted drainage anchor retaining wall structure described in Embodiment 1, including the following steps:

[0046] 1) According to the geological survey data, determine the construction position of the retaining wall structure.

[0047] 2) Excavate and clean the rock and soil on the slope surface according to the design, and then select the appropriate construction method to construct the anchor 2 according to the designed anchor position, size, strength grade, etc., and ensure that the anchor 2 is exposed to a sufficient length of reinforced steel bars , so as to connect with retaining wall 1.

[0048] 3) Drainage holes are constructed in the rock and soil mass behind the wall, and drainage pipes 6 are pierced. Wherein, the drain pipe 6 is exposed to a certain length.

[0049]4) According to the designed retaining wall size, strength grade, etc., select an appropriate construction method to construct the re...

Abstract

The invention provides a wall-mounted draining anchor rod barricade structure and a construction method thereof. The barricade structure comprises a longitudinal beam embedded in the top of a bank slope, a barricade and an anchor rod. The barricade is arranged at a by-water side of the bank slope. The longitudinal beam is positioned at a fundamental inner side of a protected bridge pile foundation. A plurality of cross beams is connected between a barricade body and the longitudinal beam. The construction method for the barricade structure comprises steps of constructing the anchor rod, constructing a draining hole, constructing the barricade, constructing an anchor pile, constructing the longitudinal beam, constructing the cross beams and installing a cut-off valve and the like. The barricade structure is capable of effectively solving problems existing in a large-scale reservoir hydro-fluctuation belt bank side cleugh area bridge pile foundation protecting technology, and advanced intechnology, and well in economy.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a wall-mounted drainage bolt retaining wall structure. Background technique [0002] The drawdown area of ​​the reservoir is a special area where the submerged land around the reservoir is periodically exposed to the water surface due to the periodic fluctuation of the water level of the reservoir. Large-scale reservoirs often have very large drawdown zones. For example, the height of the drawdown zone of the Three Gorges Reservoir Project on the Yangtze River, which was built in 2009, is as high as 30m. 60m. Due to the periodic immersion of reservoir water and groundwater and the infiltration of groundwater, the rock and soil mass in the drawdown area of ​​the reservoir is more strongly weathered, which makes the phenomenon of reservoir bank reconstruction occur from time to time. When there are buildings (structures) on the banks of the reservoir, the reconst...
