Abstract

A kind of high slope Permeable interlayer trapping method, Permeable interlayer is filled on the inside of rubble bulkhead building, and using horizontal drill at hydrophobic pore within the scope of Permeable interlayer, the drain pipe for being formed with mesh-shape drain hole is built in rubble bulkhead by the insertion of hydrophobic pore, water flow in Permeable interlayer is most of from mesh-shape drain hole inflow drain pipe, and the open drain in roadside outside rubble bulkhead is discharged to along drain pipe.This method builds rubble bulkhead and installation drain pipe in construction when digging side slope from top to bottom, once succeed when construction, reduce high slope Permeable interlayer processing when difficulty of construction, improve construction efficiency, improve construction and using when safety and avoid high construction cost caused by due to a large amount of construction drainages bright ditch.

Description

A kind of high slope Permeable interlayer trapping method

Technical field

The invention belongs to highway construction technology fields, are related to a kind of high slope Permeable interlayer trapping method.

Background technique

Under common construction environment, the most common processing method of high slope Permeable interlayer is that coagulation is used at Permeable interlayer Soil or cyclopean concrete build a large amount of bright ditch to be drained and be sluiced, and the draining in roadside is pooled to by a large amount of bright ditch Bright ditch.Such method expends a large amount of man power and material in work progress, and the open drain on high slope top is met in use process Water is easy to collapse.

In short, use is common, gutter drainage has the following disadvantages: 1, difficulty of construction is big, and construction efficiency is low；2, construction stability Property cannot be guaranteed；3, security risk is big when constructing and use；4, it needs to build a large amount of bright ditches, increases construction cost；5, hydrophobic Poor processing effect.

Summary of the invention

The object of the invention is that overcoming above-mentioned the deficiencies in the prior art, and provide a kind of permeable folder of high slope Layer trapping method, this method builds rubble bulkhead when digging side slope from top to bottom in construction and installs drain pipe, one when construction Secondary success reduces difficulty of construction of the high slope Permeable interlayer in processing, improves construction efficiency, improves construction and use When safety and avoid high construction cost caused by due to a large amount of construction drainages bright ditch.

As above design, the technical scheme is that a kind of high slope Permeable interlayer trapping method, it is characterised in that: It builds and fills Permeable interlayer on the inside of rubble bulkhead, and use horizontal drill at hydrophobic pore within the scope of Permeable interlayer, will make There is the drain pipe of mesh-shape drain hole to build in rubble bulkhead by the insertion of hydrophobic pore, the water flow in Permeable interlayer it is most of from Mesh-shape drain hole flows into drain pipe, and the open drain in roadside outside rubble bulkhead is discharged to along drain pipe.

Above-mentioned drain pipe uses pvc pipe.

The big 10-20mm in aperture of the aperture ratio drain pipe of above-mentioned drain pipe reserving hole.

By setting drain pipe, as main drainage device, it is bright that the masonry draining in high slope is greatly saved in the present invention The construction cost of ditch.Meanwhile most of water in Permeable interlayer flows to outside by drain pipe, alleviates rubble bulkhead behind Active earth pressure and water pressure, also save construction cost, increase the overall stability of side slope, more in construction and use There is safety guarantee.

Fig. 2 is that high slope Permeable interlayer mesh-shape PVC drain pipe handles side view；

Fig. 3 is the plan view of mesh-shape PVC drain pipe；

Fig. 4 is rubble bulkhead schematic diagram.

Specific embodiment:

A kind of high slope Permeable interlayer trapping method, its specific construction procedure are as follows:

1, side slope is dug according to the given ratio of slope of the design of high slope and specification, what a step is every 4-6 meters dug and build slabstone 3, and medium coarse sand gravel pervious bed 4 among slabstone and side slope is filled during masonry, and in PVC drain pipe position preformed hole Hole.

2, mesh-shape drain hole 2 is processed into according to the size of permeable amount in PVC hydrophobic pipe surface, the size of drain hole and It calculates and determines away from the sluicing maximum provided according to practical geology exploration report.

3, the rubble bulkhead that will be laid reserves hole site in PVC drain pipe and uses horizontal drill pore-forming, aperture ratio PVC The PVC drain pipe processed is inserted into the wall of side slope, and will be sealed outside reserving hole by caliber general goal 10-20mm.

The present invention is not limited to embodiments described above.Above the description of specific embodiment is intended to describe and say Bright technical solution of the present invention, above-mentioned specific embodiment are only to illustrate, and are not restrictive.This hair is not being departed from In the case of bright objective and scope of the claimed protection, those skilled in the art can also do under the inspiration of the present invention The specific transformation of many forms out, within these are all belonged to the scope of protection of the present invention.
