Abstract

The utility model discloses a kind of karst talus anchor pole reinforcement retaining structure, including mini pile (1), described mini pile (1) passes perpendicularly through grouting and reinforcing body (3) build-in on complete basement rock, and grouting and reinforcing body (3) has mini pile cushion cap (2).This utility model is according to this problem of talus slump; it is combined into an entirety by mini pile (1), mini pile cushion cap (2) and grouting and reinforcing body (3); the problem avoiding talus leading edge local slump, also solves the problem being caused extensive slump by talus leading edge local slump simultaneously;Owing to mini pile (1), mini pile cushion cap (2) and grouting and reinforcing body (3) to be formed the structure of similar barricade, the beneficially stability in the large of talus.

Description

A kind of karst talus anchor pole reinforcement retaining structure
Technical field
This utility model relates to a kind of karst talus reinforcement retaining structure, particularly relates to a kind of talus avalanche reinforcement and props up gear knot Structure.
Background technology
Talus is rock hillside unstability under various physics, chemical action, produces, peels off, forms rock not of uniform size Fragment, landwaste, carry, pile up the incompact-deposit bodies of formation under elemental effect, and the harmful engineering ground belonging to classical produces Thing.And concentrate on bottom karst depression and the talus in area, flat gradient, it is characterized in overall in steady statue, locally avalanche block Stone is steeper or unsettled due to residing slope, plays pendulum or basicly stable state.Talus avalanche treatment measures bag at present Include the measures such as barricade, friction pile, anchor pole (rope), when these measures are reinforced for local talus, more or less there is construction cost Height, requires the problems such as high and complicated construction technique for construction working face.The simplest by a kind of construction technology, low cost Honest and clean, that work progress is safe and simple ruggedized construction, carries out the preventing and treating of talus local slump, and then avoids talus slump on a large scale Problem, be karst depression geological hazard control problem needs solve engineering roadblock.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of karst talus anchor pole reinforcement retaining structure, to solve at rock The local slump of molten depression endogenous cause of ill talus and the talus slump problem on a large scale that causes, guarantee this ruggedized construction technique letter simultaneously Single, with low cost, work progress safety.
Organization plan of the present utility model is: a kind of karst talus anchor pole reinforcement retaining structure, including mini pile, mini pile Pass perpendicularly through grouting and reinforcing body build-in on complete basement rock, grouting and reinforcing body has mini pile cushion cap.
Grouting and reinforcing body by M30 cement mortar to the talus perfusion filling in the bottom of mini pile cushion cap and rearward extent Become.
Mini pile cushion cap is formed by C30 concreting, and pours on grouting and reinforcing body along landform.
Mini pile by the vertical anchor pole of three a diameter of 25 millimeters be arranged symmetrically with, by vertical spacing be 300 millimeters straight Footpath is that the stirrup colligation of 8 millimeters becomes steel reinforcement cage, irrigates M30 cement mortar and make in the stake holes of diameter 120~180 millimeters.
Mini pile embeds the complete basement rock degree of depth and is not less than 6 meters.
Mini pile horizontal layout is quincunx, and the spacing of the adjacent stake holes of any two is 1 meter.
Karst talus anchor pole reinforcement retaining structure of the present utility model includes mini pile, mini pile cushion cap and grouting and reinforcing body These three major part, the cross section of mini pile is the circular cross-section of diameter 120~180 millimeter, and build-in is in complete basement rock The degree of depth is not less than 6 meters.By M30 cement mortar to the talus perfusion filling in the bottom of mini pile cushion cap and rearward extent, shape Become grouting and reinforcing body.Mini pile layout in the plane is quincuncial arrangement, and the spacing of any two adjacent holes is 1 meter.Micro- Type pile framing pours along landform.
This utility model has the beneficial effect that following aspect:
A kind of overall structure approximating barricade, this structure is defined by mini pile, mini pile cushion cap and grouting and reinforcing body Talus by mini pile with to mini pile cushion cap bottom and back carries out cement mortar perfusion filling, makes the talus of perfusion filling Form grouting and reinforcing body, can effectively reinforce the talus at mini pile cushion cap bottom and back, it is to avoid talus leading edge local slump Possibility, the problem simultaneously also solving the extensive slump of accumulation body caused by talus leading edge local slump, be also beneficial to The monolithic stability of talus.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation plane graph (in figure, stake holes pitch-row is 1000mm, i.e. 1m);
Fig. 2 is this utility model structural representation profile.
Detailed description of the invention
As in figure 2 it is shown, a kind of karst talus anchor pole reinforcement retaining structure, including mini pile 1, mini pile cushion cap 2, slip casting adds Solid 3.
At the talus of the bottom and back of planning to build mini pile cushion cap 2, use the perfusion filling of M30 cement mortar, form note Slurry reinforcing body 3, slip casting fullness coefficient should be more than 1.0;
The construction of mini pile 1 comprises the following steps.
Step one, positioning and correct perpendicularity: pile position deviation should control within 20 millimeters, the perpendicularity deviation of straight stake should Less than 1%.
Step 2, pore-forming: boring layout sees accompanying drawing 1, uses geological drilling rig pore-forming.Can use during boring mud off or Clear water retaining wall, setting of casing pore-forming.Clear hole after being bored into designed elevation.
Step 3, hang steel reinforcement cage and Grouting Pipe: substep hangs steel reinforcement cage, and Grouting Pipe can use 20 millimeters of iron pipes of diameter, At the bottom of straight cutting hole.The time of hanging should be shortened during construction as far as possible.
Step 4, slip casting: preferably use the grouting pump of can hold concurrently cement injection and mortar, maximum working pressure (MWP) should be not less than 1.5 MPa, secondary grouting, pressure should be controlled during slip casting, make serosity uniformly on emit, till glowing aperture.
After mini pile 1 construction, the formwork carrying out mini pile cushion cap 2 pours, and uses C30 concreting, along landform Pour.
