Abstract

The utility model relates to a manual digging pile reinforced concrete wall protection, the cast-in-place reinforced concrete wall protection is replaced by a thinning reinforced concrete precast block, the foundation round pile is an arc precast block and is bolted by en embedded angle steel, the anchor pile and the foundation square pile are plane precast blocks and are clamped and fixed at stratum by a mortar bolt, the center of the precast block is provided with grouting holes, and the back is provided with embossing, the lateral is provided with a glued layer. This digging pile wall protection can largely save the amount of wall protection concrete, the societal and economic benefit is significant; the measurement of waterproof and drainage and ensuring the stability of the wall protection is simple and reliable; in addition, the installation is convenient and construction period is short.

Description

Hole digging pile gives the system steel reinforced concrete dado

The utility model relates to a kind of hand excavated pile and gives the system steel reinforced concrete dado.

Hand excavated pile has foundation pile of building and massif antiskid anchor pile two big classes, be basic pattern and the unique pile pattern (once met a building site and use drilled pile to make massif antiskid anchor pile) of massif antiskid anchor pile that is widely used in an economic and reliable of civil works because of the unreasonable structure failure is discarded.The excavation pile construction pile does not need large and medium-sized facility, and cost is low, and the mountain region construction has more its convenient advantage.Protection wall of bored pile is a kind of stressed temporary construction of pile body of not participating in.During construction, generally be to dig out earlier a joint stake hole, reinforcing bar be installed then propped up template that placing of concrete more at last is by the joint pore-forming in the building site.Its reinforcement installation and concrete casting execution conditions are poor, and quality be difficult for to guarantee, must thickening retaining wall size, so waste raw material, time-consuming also effort poor stability in this way.

The purpose of this utility model provides a kind of hole digging pile and gives the system steel reinforced concrete dado, with the system of the giving steel concrete retaining wall replacement cast-in-situ steel reinforced concrete retaining wall of attenuate, and is aided with the relative configurations measure, saving retaining wall concrete that can be more.

The purpose of this utility model is achieved in that hole digging pile gives system steel reinforced concrete dado every joint and gives clamp dog 1 by 4-8 and form, and the back side of giving clamp dog 1 has embossing 2, mid portion to have mud jacking hole 7, the outside that glued layer 3 is arranged.

This hole digging pile gives the system steel reinforced concrete dado, can give clamp dog 1 by four arcs and form and give system ring, and the both ends of giving clamp dog 1 are respectively the convex-concave arc surface, are having connecting angle 4 and connecting bolt 5, bottom surface, top to be respectively parallel monocline face near the inboard, end.There is the hoop 6 and hang over hanger 8 on the hoop 6 of putting more energy into of putting more energy into of the band tightener 9 that recycles the inboard of giving system ring.

Another kind of hole digging pile described in the utility model gives the system steel reinforced concrete dado, gives clamp dog 1 by 4-8 planes and forms and give the system square frame, and the mid portion that gives clamp dog 1 has anchor hole 12 and anchor pole 10.There is the stiffening frame 11 that recycles the inboard of giving the system square frame and hangs over hanger 8 on the stiffening frame 11.

The utility model compared with prior art, advantage is as follows:

1. save the breast wall concrete consumption, foundation pile can save 56,1-62,8%, anchor pile is 48,0 one 69,8%, thereby can reduce its cost significantly, with the Yunnan highway is example: building foundation pile 30 ten thousand steres every year, only count 1/3 and be hole digging pile, can save more than breast wall concrete 3 ten thousand steres, building more than anchor pile 15 ten thousand steres, can save breast wall concrete 2.8～3.2 ten thousand steres, two totals surpass 6 ten thousand steres, breast wall concrete is in 400 yuan/cubic metre of highway bid prices, about 2,400 ten thousand yuan/year of cost can be saved, also retaining wall amount of reinforcement, considerable benefit can be saved;

2. easy for installation, give the clamp dog substance and hang the native ability of the hanging design of adorning by existing borehole, short construction period, every construction sections can be saved concrete pouring and conditioned time;

3. anti-draining and assurance retaining wall stabilizing measures are easy to be reliable.

Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing, but structure of the present utility model is not limited to shown in the accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a scheme of installation of the present utility model.

Fig. 3 is along the sectional view of I-I face among the utility model Fig. 2.

Fig. 4 is the structural representation of another kind of retaining wall of the present utility model.

Fig. 5 is the scheme of installation of another kind of retaining wall of the present utility model.

Fig. 6 is along the sectional view of II one II face among the utility model Fig. 5.

Among Fig. 1, every joint retaining wall gives clamp dog 1 by four arcs and forms and give system ring, give clamp dog 1 back side embossing 2 is arranged, every is given clamp dog 1 both ends is respectively that convex-concave arc surface, bottom surface, top are parallel monocline face, give near the inboard, end and to bury two connecting angles 4 and connect, give the system ring outside and fill glued layer 3 with the ground interlayer by connecting bolt 5; Among Fig. 2, when every joint is installed, give the 6 liang of groups of using when the system ring is inboard the location of hoop of temporarily putting more energy into, these hoop 6 band tighteners 9 of putting more energy into are that dismountable its gone up the hoop 6 of putting more energy into of a joint retaining wall after this joint retaining wall is finished, for saving use under it until last recovery; Among Fig. 3, giving clamp dog 1 mid portion has 5 mud jacking holes 7, hangs with hanger 8 on the hoop 6 of putting more energy into down.Its vertical, laterally contraposition is convenient on the parallel inclined-plane up and down of hanger 8 and prefabricated section.

Fig. 4 is another kind of retaining wall, and every joint gives clamp dog 1 by 4 or 6 or 8 flat boards to be formed and give the system square frame, and giving clamp dog 1 back side has embossing 2, and giving the system square frame outside has glued layer 3, anchor pole 10; Among Fig. 5 and Fig. 6, giving clamp dog 1 mid portion has the anchor hole 12 of reservation and mud jacking hole 7.Anchor pole 10 makes prefabricated section 1 and the stratum pincers is solid on every side, when every joint is installed, give system square frame inboard interim location 11 liang of groups of stiffening frame are arranged, the partial component band tightener 9 of stiffening frame 11, after this joint retaining wall was finished, the stiffening frame 11 of a dismountable last joint retaining wall was for joint use down, until last recovery, hang with hanger 8 on the following stiffening frame 11 and be convenient to give the clamp dog contraposition.This system square frame retaining wall that gives can be used for anchor pile, the stake of basis side.
