Abstract

A kind of gutter construction method, construction of slope drain in geologically unstable area particularly, its master operation is: in time pour into the soft sticking fluid sealant of oiliness in the groove behind excavation, sealing scar slit, on fluid sealant, lay the braiding water proof cloth of one deck softness, retractility Water penetrative flexible pipe, macadam, barrier paper and reinforcement wire gauze, cement paste is established in spray more at last, finishes the ditch body; For further making the ditch body stable, lay turf in the bank both sides, and, the band that intercepts water that is filled with pitch is set from the suitable distance of bank.Build the gutter with the present invention in unstable geology district, can prevent that rainwater from infiltrating the rock stratum, guarantee the strong stable of gutter.

Description

Construction of slope drain in geologically unstable area

The present invention relates to a kind of gutter construction method, particularly construction of slope drain in geologically unstable area.

Always in unstable geology district, build the gutter as geological provinces such as mud stone, mostly be brick, mortar flag stone, concrete or reinforced concrete prefabricated structure of building by laying bricks or stones, these gutters, during because of construction, geology is disturbed, on every side mud stone when summer high temperature, dry and cracked weathering, during summer rainfall, the crack becomes water-flowing path, especially at ditch body structure beyond the region of objective existence side and domatic joining place, often its substrate is washed in a pan empty by current scour, sunk in the gutter, crumble, so on unstable geology district domatic, how to build the gutter, become a hard nut to crack in the civil works.

Purpose of the present invention is that construction of slope drain in geologically unstable area such as a kind of mud stone will be provided, the gutter of building with this method, when even the concrete ditch body produces crack or fracture, still seepage water effectively can be cut and lead, make the condition of a disaster control to minimum zone, and be easy to remedy.

The object of the present invention is achieved like this: this construction of slope drain in geologically unstable area is the timely soft sticking fluid sealant of perfusion oiliness in the groove behind excavation, sealing scar slit, on fluid sealant, lay the braiding water proof cloth of one deck softness, the retractility Water penetrative flexible pipe, macadam, barrier paper and reinforcement wire gauze, cement paste is established in spray more at last, finishes the ditch body; For further making the ditch body stable, lay turf in the bank both sides, and, the band that intercepts water that is filled with pitch is set from the suitable distance of bank.

There is following advantage in gutter of the present invention:

1. the gutter can adapt to unstable geology, solid and reliable: because of the gutter of being finished, the rock crevice of bottom of trench and both sides is all sealed by soft sticking fluid sealant, can soften the generation displacement during sealing glue high temperature, can in time fill up the crack that geology Yin Gaowen cracking is produced, and there is the gunite layer of reinforcing with wire gauze on the top layer, by macadam infiltrate in the Water penetrative flexible pipe moisture content can along with the isolated pipeline of top layer bottom in discharge, so can absorb the irregular settlement of certain degree, prevent that large tracts of land is because of caving in that infiltration produces.

2. help maintenance and maintenance: intercept water band and lay turf on the surface because of the both sides, gutter are provided with, plant careless bank protection, the gunite rough surface of ditch body infiltrates bottom of trench and the ditch body has a little distortion also to study for a second time courses one has flunked easily even old place table water electrode is difficult.

3. construction speed is fast, the efficient height: adopt the gunite layer because of the ditch surface, need not build stone or precast concrete block by laying bricks or stones, and in the gunite, as add the strong agent of drought, and more can improve its rate of set, be delivered for use early.

Concrete construction method of the present invention is provided by following examples and accompanying drawing thereof:

Fig. 1 is the past gutter schematic diagram.

Fig. 2 is that the present invention is applied to the domatic schematic perspective view of going up of mud stone.

Fig. 3 is I-I section enlarged diagram of Fig. 2.

Describe in detail below in conjunction with accompanying drawing:

With reference to Fig. 1, the gutter on mud stone face 1 previously, corresponding measure for want of, 101 places, ditch body prefabricated section 10 outsides are very easily because of being subjected to the current scour avalanche.

With reference to Fig. 2,3, the present invention is undertaken by following operation: in the good groove of excavation, in the both sides and the bottom of trench of ditch body 2, dispose weathering or loosening unstable rock, pour into the soft sticking fluid sealant 3 of oiliness immediately, as mulseal, pitch class material, be full of ditch side 21, fill up slit 11 on the scar 1; On fluid sealant 3, lay the soft braiding of one deck rubber-like water proof cloth 6, on water proof cloth 6, lay 1～3 Water penetrative flexible pipe 7, on Water penetrative flexible pipe 7, fill out multiple macadam 8; On macadam 8, lay one deck barrier paper or isolation cloth 9, and follow closely on the ditch body, prevent that upper water mud from infiltrating with iron nail 91; At barrier paper or 1～2 layer of wire gauze 92 of isolation cloth 9 upper berths nail, spray lays cement and starches 93 then.

In addition, for further preventing, protect domaticly, from bank 22 suitable distances, be provided with to ditch body 2, and be filled with intercepting water of pitch 51 therein and be with 5 in ditch body 2 both sides to bottom of trench infiltration, and along two outer rims layings of ditch body turf 4 banks 22 that go directly.

Claims

1, a kind of gutter construction method, particularly construction of slope drain in geologically unstable area is characterized in that being undertaken by following operation:

1) in the good groove of excavation,, disposes weathering or loosening unstable rock, pour into the soft sticking fluid sealant 3 of oiliness immediately,, be full of ditch side 21, fill up slit 11 on the scar 1 as mulseal, pitch class material in the both sides and the bottom of trench of ditch body 2;

2) on fluid sealant 3, lay the soft braiding of one deck rubber-like water proof cloth 6, on water proof cloth 6, lay 1～3 Water penetrative flexible pipe 7, on Water penetrative flexible pipe 7, fill out multiple macadam 8;

3) on macadam 8, lay one deck barrier paper or isolation cloth 9, and follow closely on the ditch body, prevent that upper water mud from infiltrating with iron nail 91;

4) at barrier paper or 1～2 layer of wire gauze 92 of isolation cloth 9 upper berths nail, spray lays cement and starches 93 then.

2, slope, unstable geology district according to claim 1 and gutter construction method is characterized in that in ditch body 2 both sides being provided with to ditch body 2 from bank 22 suitable distances, and are filled with intercepting water of pitch 51 therein and are with 5.
