Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the examples.

[0045] Such as figure 1 , 2 Shown in the figure: drainage anti-slide pile 1, drainage tunnel 2, sliding surface 3, ground water level line 4, slope foot water level 5, slope surface 6, different strata A~E, E is bedrock; Taking excavator construction as an example, the construction of drainage anti-slide pile-drainage tunnel structure includes the following steps:

[0046] ① Leveling the site: leveling the construction site to facilitate the smooth entry of machinery and materials into the site.

[0047] ②Measuring stakeout and pile position: according to the approved leveling results, use the total station to stake out accurately, set up protective stakes around them after stakeout and retest to ensure that the error meets the specification requirements, and then mark around the stakes , to prevent mechanical displacement from destroying the pile points and at the sam...

Abstract

The invention discloses an anti-slide pile-tunnel structure suitable for hydrodynamic type landslide, and a construction method thereof. The anti-slide pile-tunnel structure suitable for hydrodynamictype landslide comprises a drainage anti-slide pile and a drainage tunnel, wherein the bottom part of the drainage anti-slide pile is of a solid structure; the upper part of the drainage anti-slide pile is of a hollow structure; a water guiding channel is arranged on the bottom part of the hollow structure; a flow measuring device is arranged on the water guiding channel; a stress monitor is arranged on the outer side of a pile body of the drainage anti-slide pile; a drainage channel is arranged on the top part of the drainage tunnel; and a stress monitoring and early-warning device is arranged in the drainage tunnel and is connected with the stress monitor. The anti-slide pile-tunnel structure suitable for hydrodynamic type landslide provided by the invention has multiple functions of draining in a landslide mass, retaining, protecting, monitoring, early warning and the like, is combined with a protection measure of the drainage tunnel so as to have a good drainage effect in protecting and controlling large hydrodynamic type landslide caused by rainfall, a reservoir water level and underground water, and has a better engineering application value in the control of hydrodynamic type landslide.

Description

technical field [0001] The invention relates to a civil engineering and water conservancy engineering device and a construction method thereof, in particular to an anti-slide pile-tunnel structure and a construction method thereof. Background technique [0002] Hydrodynamic landslides mainly refer to the rock and soil instability of slopes or reservoir bank slopes driven by hydrodynamic factors such as rainfall, reservoir water level changes, surface runoff, and groundwater activities. [0003] For hydrodynamic landslides, the main prevention and control measures are drainage. Drainage is divided into surface drainage and underground drainage. When drainage treatment cannot meet the stability requirements, drainage anti-slide piles are used for support and protection. However, the drainage anti-slide piles currently used for landslide control have a high cost of prevention and control engineering, and the independent setting of drainage measures, prevention measures and moni...
