Embodiment 1

[0065] Such as figure 1 and figure 2 As shown, the mechanism for anti-destructive reinforcement of geotechnical engineering includes a foundation pit support assembly, and the foundation pit support assembly includes two shrouds 1, and also includes a support frame for supporting the shroud 1, and the two shrouds The plates 1 are distributed on a pair of opposite sides of the support frame;

[0066] The support frame includes a vertical rod 3 and a plurality of cross bars 2 arranged along the axial direction of the vertical rod 3, and the horizontal rod 2 is used as a support between the vertical rod 3 and the inner side of the coaming plate 1, and also includes a On the vertical pole 3, there are sleeves 20 that can slide along the axis of the vertical pole 3. Two crossbars 2 are fixed on each sleeve 20, and the crossbars 2 on each sleeve 20 are relative to the axis of the sleeve 20. line symmetric;

[0067] The length of the cross bar 2 is adjustable;

[0068] It also i...

Embodiment 2

[0085] Such as figure 1 and figure 2 As shown, the present embodiment is further limited on the basis of embodiment 1:

[0086] The shroud 1 is a hollow plate structure;

[0087] The coaming plate 1 includes an outer plate for connecting with the foundation pit and an inner plate close to the center of the foundation pit, and the outer plate is provided with a plurality of communication holes 15 passing through the inner and outer sides of the outer plate;

[0088] The inner side plate is provided with a drain port 13 that runs through the inner and outer sides of the inner plate, and the fluid conduction capacity of the drain port 13 is adjustable;

[0089] It also includes a water tank 12 fixed on the inner board, and the outlet end of the drain port 13 is located in the water tank 12 . When this scheme is used in practice, the coaming 1 can be spliced ​​by multiple plates. For example, according to the internal design, for the scheme that does not use the filter screen ...

Abstract

The invention discloses a mechanism and method for geotechnical engineering anti-failure reinforcement. The mechanism comprises a foundation pit supporting assembly, the foundation pit supporting assembly comprises two surrounding plates and further comprises a supporting frame, wherein the supporting frame comprises a vertical rod and a plurality of transverse rods and further comprises a sleevewhich is arranged on the vertical rod in a sleeving mode and can slide along the axis of the vertical rod; two cross rods are fixed on each sleeve, the cross rods on each sleeve are in linear symmetryrelative to the axis of the sleeve, and the length of each cross rod is adjustable; the mechanism further comprises a lifting ring arranged at the top of the vertical rod, the downward projection ofthe lifting ring falls on the cross rod, and the axis of the lifting ring is collinear with the axis of the vertical rod; a locking device for locking the position of each sleeve on the axis of the vertical rod is arranged between each sleeve and the vertical rod; and the lifting ring is detachably connected to the vertical rod. The method is a geotechnical engineering reinforcing method based onthe mechanism, and by adopting the mechanism and the method provided by the scheme, a safe and reliable geotechnical engineering anti-failure slope reinforcing scheme can be obtained under the economical and reasonable conditions.

Description

technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to a mechanism and method for anti-destruction reinforcement of geotechnical engineering. Background technique [0002] The foundation pit generally refers to the earth pit excavated at the design position of the building foundation according to the elevation of the building foundation and the plane size of the foundation. For foundation pit construction, the foundation pit support mechanism is used as a temporary structure and a safety protection structure to prevent collapse during foundation pit construction. At the same time, during the excavation and construction of the foundation pit, the precipitation of the foundation pit needs to be considered. [0003] Sand-egg geology generally has loose and water-rich strata. In the foundation pit construction of water-rich sand and pebble strata close to important buildings, it is necessary to pay special attention ...
