Abstract
The present invention relates to a reinforced retaining wall and a columned retaining wall, which has a technical scheme that a reinforcing steel bar frame in a reticular structure or a reinforced concrete column or beam frame in a reticular structure are added to a retaining wall body in the supporting construction of side slopes, and a columned retaining wall in a type of a reinforced retaining wall is formed. The addition of the reinforced concrete column or beam has a restricting function on the retaining wall body, so that the wall body has a strong capacity for deformation. Therefore, the integral shear strength and rigidity of the retaining wall are improved, and furthermore, the capacities for resisting slip and overturn of the retaining wall are improved.
Description
The invention belongs to the barricade in the slope support engineering of civil works, particularly a kind of reinforced retaining wall and strutting barricade.
Usually the supporting barricade that adopts in engineering grouts two types of rubble barricade and steel concrete barricades.Grout the rubble barricade and belong to rigid retaining wall, material compressive strength height, the body of wall shear resistance is low, and integral rigidity is poor, easily produces the part under external force and collapses; The steel concrete barricade, material resistance to compression, shear strength are higher, the body of wall good integrity, rigidity is big, but wall stability is lower, the cost height.
The purpose of this invention is to provide a kind of reinforced retaining wall and strutting barricade, this barricade rigidity is big, good integrity, and cross dimensions is little, has stronger antiskid and moves, resists the ability of inclining and carrying out.
Technical scheme of the present invention is: add the bar frame structural skeleton in rubble, the rectangular slab of stone barricade body grouting of slope support engineering, or reinforced concrete post space truss structure skeleton, form reinforcement or strutting barricade.
Reinforced retaining wall is to arrange reinforcing bar in length and breadth at interval grouting in the rubble barricade body of slope support engineering, extends upward from the basis and forms fastening net structure skeleton, and the net structure skeleton anchors into the ground certain depth, resists the shoe that inclines, antiskid to move ability to increase reinforced retaining wall.
The net structure cross-section of its skeleton shape of above-mentioned reinforced retaining wall is consistent with the barricade cross sectional shape of design be generally up-narrow and down-wide trapezoidal.
The strutting barricade is grouting in mao factory's barricade at slope support engineering, arrange reinforced concrete post at interval in length and breadth, extend upward the fastening concrete column net structure skeleton of formation from the basis, the space truss structure skeleton anchors into the ground certain depth, resists the shoe that inclines, antiskid to move ability to increase the strutting barricade.
The net structure cross-section of its skeleton of above-mentioned strutting barricade forms consistent with the barricade cross sectional shape that designs, and is generally up-narrow and down-wide trapezoidal.
Advantage of the present invention is: owing to add netted structural skeleton of reinforcing bar or reinforced concrete post net structure skeleton in the rubble barricade grouting of slope support engineering, form reinforced retaining wall or strutting barricade.Reinforcing bar that adds or reinforced concrete post have played effect of contraction and the ground anchorage effect to body of wall, make body of wall have stronger deformability, thereby improve the globality of barricade, shear strength and rigidity, and then realized that the antiskid that strengthens barricade moves, the anti-ability of inclining and carrying out.
Further describe the present invention below in conjunction with accompanying drawing.
Fig. 1 grouts the lateral plan of rubble barricade for reinforcement.
Fig. 2 is the front view of the barricade of Fig. 1.
Fig. 3 grouts the side view of rubble barricade for strutting.
Among Fig. 1,2, foundation trench 1 is lower than ground, the degree of depth is as the criterion with the design soil supporting layer, in foundation trench 1, water the C10 concrete cushion, discharge lateral stressed reinforcing bar and longitudinal stress reinforcing bar at regular intervals, form horizontal tectonics muscle 2, plug or anchor into vertical applied force reinforcing bar 3 by design at the width of foundation trench 1 then, the junction welding or the colligation of above-mentioned reinforcing bar.After treating that concrete cushion reaches certain intensity, on concrete cushion, grout contain above-mentioned reinforcing bar grout rubble body 4, when grouting rubble (about 1～1.5 meter) to the first row of horizontal muscle height, stop to grout rubble, lay horizontal tectonics muscle 2, horizontal tectonics muscle 2 and 3 colligations of vertical applied force reinforcing bar or welding.At this moment, tamp with being higher than the cement mortar that grouts the rubble one-level between horizontal tectonics muscle 2 and vertical applied force reinforcing bar 3 and rubble.When continuing to grout ashlar, stop to grout rubble, spread second row of horizontal structure muscle 2, so repeatedly, grout the construction of rubble barricade up to reinforcement and finish to second row of horizontal structure muscle worker height.So just in above-mentioned barricade, form a net structure skeleton, in manufacturing process, the cross sectional shape of the net structure cage of reinforcement in the barricade should be provided with barricade cross sectional shape unanimity, be generally up-narrow and down-wide trapezoidal.
Fig. 3,4 strutting grout the rubble barricade: promptly each steel bar stress that grouts the net structure skeleton in the rubble barricade at above-mentioned reinforcement is changed to reinforced concrete post or beam and forms strutting and grout the rubble barricade.Its reinforced concrete post cross sectional shape is a rectangle.
Strutting grouts the concrete construction sequence of rubble barricade:
Strutting grouts rubble barricade construction sequence:
A, unwrapping wire: the strutting by design grouts the rubble barricade axially at the ground unwrapping wire;
B, dig foundation trench: grout rubble barricade section key dimension by the strutting of design and dig foundation trench on ground, the degree of depth is as the criterion to dig the design soil supporting layer;
C, build bed course: insert the reinforced concrete post reinforcing bar;
Before grouting rubble, in foundation trench, water the C10 concrete cushion, thickness is by designing requirement, and is general＞100mm.Before the concreting bed course, fixedly the reinforced concrete post reinforcing bar inserts it into basic degree, and with support that vertical reinforcement is in place;
D, grout ashlar
Treat that concrete cushion reaches certain intensity, on concrete cushion, grout ashlar behind the reinforced concrete post assembling reinforcement;
E, build first floor reinforced concrete post and reinforced concrete beam
Grout and promptly stop to grout rubble after the ashlar height reaches first floor reinforced concrete beam top mark height, set up first floor steel concrete beam steel, outside the reinforced concrete post body of wall, be situated between then and steel concrete top surface of the beam and body of wall outside formwork concreting then, make the formation of first floor reinforced concrete post and beam;
F, treat that first floor reinforced concrete post and beam reach certain intensity after, promptly begin to grout second layer ashlar, after second layer ashlar height reach a certain height, set up second layer steel concrete beam steel, then at steel concrete, make with two layers of reinforced concrete post and beam to form, so repeatedly, grout the construction of rubble barricade until whole strutting and finish.
Reinforcement or strutting are mainly considered by grouting on the random ashlar in the said method, but principle also is applicable to and is grouting woollen stone, reinforcement or strutting in the rubble concrete, or reinforcement or strutting anchor in the ground to improve barricade whole gonosome and rigidity or antiskid moves, the anti-shoe ability of inclining in the steel concrete.
F, treat that first floor reinforced concrete post and beam reach certain intensity after, promptly begin to grout second layer ashlar, after second layer ashlar height reach a certain height, set up second layer steel concrete beam steel, at reinforced concrete post wall outer side and steel concrete top surface of the beam and wall outer side formwork, concreting makes with two layers of reinforced concrete post and beam to form then, so repeatedly, grouting the construction of rubble bumping post until whole strutting finishes.
Reinforcement or strutting are mainly considered but principle also is applicable to and is grouting woollen stone by grouting on the random ashlar in the said method, reinforcement or strutting in the rubble concrete, or reinforcement or strutting anchor in the ground to improve barricade whole gonosome and rigidity or antiskid moves, the anti-shoe ability of inclining in the steel concrete.
