Abstract

The utility model discloses an expanding soil slope protection system which is built on an expanding soil slope. The system mainly comprises a geomembrane laid on the expanding soil slope, and vine plants, wherein the geomembrane is covered with the vine plants; a plurality of piles knocked into the expanding soil slope are arranged on the corresponding slope face of the geomembrane, and the positions, corresponding to the circumferences of all the piles, of the geomembrane are sealed through asphalt. The expanding soil slope protection system is reasonable in structural design and high in construction speed and meanwhile has the advantages of being good in protection effect, firm in structure and durable, a new path is provided for expanding soil slope protection, and the expanding soil slope protection system can be widely applied to protection of expanding soil slopes for highways, railways, water conservancy projects and other projects.

Description

A kind of expansion slight slope guard system

Technical field

This novel Foundation Design that relates to is built field, specifically refers to that a kind of expansive soil slope of protecting prevents that it from the guard system destroying occurring.

Background technology

Expansive soil is to Hydroclimate condition responsive, volume expansion after immersion, and dehydration after-contraction, easily causes crack to produce, and crack exists has on the one hand increased itself and atmosphere contact area, promotes to evaporate, and crack further increases expansion; On the other hand, strengthened rainwater and surface water infiltration capacity, the soil body produces expansion force, strength decreased, and deadweight increases, and slope body produces distortion, further promotes crack propagation.The generation in crack reduces stability and the soil body corrosion resistance of side slope.Therefore, the expansion slight slope forming for engineering excavation, it is very important carrying out side slope protection.

At present, expansion slight slope means of defence comprises methods such as adopting geomembrane, pitch, concrete lining, cement mortar, stone block building, and every kind of method has its applicable elements and pluses and minuses.Such as geomembrane interface friction force is less and be afraid of Exposure to Sunlight, concrete, piece stone belong to rigid protection, if deal with improperly, easily produce cracking, etc.In addition, the slight slope guard system that expands is at present difficult to take into account the performances such as rapid construction, sound construction is durable, protection effect is excellent.

In view of this, the problem that the inventor exists for existing expansion slight slope guard system conducts in-depth research, and this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of expansion slight slope guard system, has the features such as speed of application is fast, protection effect good, sound construction is durable simultaneously.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of expansion slight slope guard system, constructs on expansion slight slope, mainly comprises the geomembrane being laid on expansion slight slope and covers the vine plant on this geomembrane; The domatic position of correspondence of this geomembrane is evenly built and is provided with the some pile bodies of squeezing in expansion slight slope, and on this geomembrane, corresponding each pile body week adopts bituminous seal along place.

What the top, slope of described geomembrane was located to be preset with on corresponding expansion slight slope intercepts water to cheat to form a catchwater; The drain being preset with on the corresponding expansion slight slope in toe place of described geomembrane forms a gutter.

The top, corresponding slope of described geomembrane and the upper and lower end parts of toe are embedded under the soil body of expansion slight slope.

Described geomembrane is HDPE film.

Described pile body is small-sized reinforced concrete pile.

Adopt after such scheme, this Novel photo is for the beneficial effect of prior art: utilize the barrier properties that geomembrane is good, prevented that the surface water such as rainfall from penetrating in the expansion slight slope soil body; Utilize pile body that geomembrane is fixed on expansion slight slope firmly, prevent that it from sliding, pile body is again for the firm climbing of vine plant provides support simultaneously; Utilize bituminous seal to live the gap between pile body and geomembrane, prevent that current from entering geomembrane bottom; Utilize vine plant, cover geomembrane, prevent strength decreased after the long-time Exposure to Sunlight of geomembrane.This expansible soil guard system reasonable in design thus, speed of application is fast, also have that protection effect is good, the durable feature of sound construction simultaneously, for the protection of expansion slight slope provides a kind of new approach, can be widely used in the Protection of Expansive Soil of the engineerings such as highway, railway, water conservancy.

Label declaration

Geomembrane 1 vine plant 2

Pile body 3 pitches 4

Catchwater 5 gutters 6

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this case is described in further detail.

This case relates to a kind of expansion slight slope guard system, constructs on expansion slight slope, as shown in Figure 1, mainly includes geomembrane 1, vine plant 2, pile body 3 and pitch 4.

Geomembrane 1 is laid on expansion slight slope, and this geomembrane 1 preferably has the HDPE film compared with high-tensile and good barrier.Vine plant 2 is preferably planted in toe and Po Dingchu, and it covers on geomembrane 1.Pile body 3 is built the domatic position of correspondence that is located at geomembrane 1, and pile body 3 is provided with some, and it is evenly on domatic arranges; Preferably, pile body 3 is small-sized reinforced concrete pile, and stake is long is 50cm, is cone.Pitch 4 is located at corresponding each pile body on geomembrane 1 and is played gap between sealing pile body 3 and geomembrane 1 along place in 3 weeks; Pitch 4 can be common coal tar pitch or petroleum bitumen.

Preferably, the top, corresponding slope of described geomembrane 1 and the upper and lower end parts of toe are embedded under expansion slight slope, are attached to securely on expansion slight slope and act on for strengthening geomembrane 1.Have, top, the slope place of expansion slight slope can be preset with the hole of intercepting water again, and forms and has a catchwater 5 in the hole of intercepting water described in top, the slope place of geomembrane 1 correspondence, works the effect of intercepting water.The toe place of expansion slight slope can be preset with a drain, and the corresponding described drain in toe place of geomembrane 1 forms a gutter 6, plays drainage.

When Specific construction, first excavate respectively at top, slope and the toe place of expansion slight slope intercept water hole and drain; Establish one deck geomembrane 1 in expansion slight slope upper berth afterwards, intercept water hole and drain place formation of correspondence has catchwater 5 and gutter 6; Certain depth place in the soil body is all imbedded at the top, corresponding slope of geomembrane 1 and the both ends up and down of toe; Then at a certain distance pile body 3 is passed to geomembrane 2, be driven in the slight slope soil body, then seal with pitch 4 with contacting on gap of geomembrane 1 at pile body 3, finally, at toe and top, slope place plantation vine plant 2, complete the construction of whole guard system.

The foregoing is only this novel preferred embodiment, all equalizations of doing with this novel claim scope change and modify, and all should belong to the scope of this novel claim.
