Abstract
The invention provides a construction method for a local water eruption source of an underground damp proofing course. The construction method comprises the steps of 1) prefabricating a fine aggregate concrete block, and embedding a draining guide pipe through the concrete block; 2) finding out the position of the water eruption source, and deepening a small pit in the position; 3) sleeving the lower part of the draining guide pipe with a steel wire ball, then feeding into the deepened small pit together with the concrete block and the draining guide pipe, and paving a steel wire gauze using the position of the water eruption source as the center; 4) extruding, discharging water and normally pouring course concrete to the position to enable water to be naturally erupted from the draining guide pipe and then stop on the concrete layer, wherein the depth of 60 to 90mm is reserved without concrete; 5) enabling the pouring layer of the course to be 200mm higher than the normal water eruption stopping level if the water eruption point is a similar independent column base; 6) maintaining in a normal way, then bending the draining guide pipe in 180 degrees, and binding with an iron wire to close the water source; 7) transferring the draining water guide to the rest part without concrete, and then filling in concrete to cover the draining guide pipe. According to the construction method, the construction process is simple, the damp base layer is at least free of open water, the quality is ensured, the cost is low, the energy is saved, and the environment is protected.
Description
Technical field
The present invention relates to a kind of underground waterproof basic unit local and emit water source construction method, for building field.
Background technology
Underground waterproof construction is the problem that enterprise in charge of construction compares concern always, and the construction method of waterproof matrix determines waterproof construction quality to a great extent.And current more situation is, construct by force when there being open fire, its consequence is that waterproofing course does not play waterproof action, when main body waterproof concrete existing defects, there will be Seepage, therefore there is waterproof construction mass defect.Therefore how waterproof matrix solves and locally emits the water source bright water problem of impact elimination to be the significant problem of enterprise in charge of construction in underground waterproof construction.
Summary of the invention
Goal of the invention: the object of the invention be to provide a kind of underground waterproof basic unit local emit water source construction method, be applicable to due to reach be excavated to design elevation time, occur in soil some local upwards outwards emit the situation of water and do not take precipitation measure project.
Technical scheme of the present invention is as follows: a kind of underground waterproof basic unit local emits water source construction method, comprises the steps:
1) prefabricated pea gravel concreten block, by pre-buried for drainage duct through concrete block,
2) find and emit position, water water source and deepen little heatable adobe sleeping platform in this position,
3) steel wire lump is enclosed within drainage duct bottom and puts into the little heatable adobe sleeping platform of intensification together with concrete block and drainage duct, centered by the position that this emits water source, lay gauze wire cloth.
4) adopt extruding to catch up with water normally to water and smash substrate concrete to this position, emit water nature to emerge from drainage duct, and stay in concrete surface, this place stays 60-90mm deeply not water,
5) if emit the similar single column foundation of water spot, basic unit waters the face of smashing and exceeds and normally emit water to cut off the water face 200mm,
6) normal after maintenance 10-15 days by drainage duct double flat iron wire tighten, can water source be closed,
7) drainage duct is put in does not water residue place, fill with concrete and bury drainage duct, complete whole closed water source process.
Described pea gravel concreten block is 80mm × 80mm × 80mm.
Described drainage duct is long 350-400mm, and internal diameter is the PVC transparent flexible pipe of 8mm.
Described drainage duct is pre-buried is that 50mm is stretched out in bottom through concrete block, and 220-270mm is stretched out on top.
The little heatable adobe sleeping platform of described intensification is for adding profound 80mm × wide 80mm × dark 210mm.
Described steel wire lump is enclosed within the 50mm that concrete block is stretched out in drainage duct bottom.
Described laying gauze wire cloth is 1000mm × 1000mm.
Know-why of the present invention is as follows:
Measure is dredged in employing, the water source flowing water pressure that makes to emerge is discharged when large area waterproof matrix concrete normally waters and smashes, water source flowing water pressure of avoiding emerging smashes the also unhardened concrete quality influence of large area waterproof matrix not reaching intensity to newly watering, newly water if do not process smash go back green concrete be very easy to again be separated into independently stone, sand and cement, ensure large area waterproof matrix concrete quality, after closing drainage duct, substrate concrete can bear the water buoyancy of water source flowing water pressure of emerging and the effect of preliminary leak pressure, accomplish base closed water source, reach waterproof matrix at least without the waterproof construction condition of open fire, ensure waterproof quality.
Outstanding advantages of the present invention is:
1, construction technology is simple.This method is identical with common disturbing concrete, and operational method is simple, and operative is convenient.
2, can ensure the quality of products, provide against hidden trouble, reduce cost.Can base closed water source, reach waterproof matrix at least without the waterproof construction condition of open fire, ensure the quality of products.
3, energy-conserving and environment-protective.Material requested can repeat turnover and use, and embodies the feature of energy-conserving and environment-protective.

Fig. 2 is the state diagram after underground waterproof basic unit of the present invention local emits water source construction method to construct.
Be labeled as in figure: drainage duct 1, steel wire lump 2, precast concrete block 3, gauze wire cloth 4, deepen little heatable adobe sleeping platform 5.
Detailed description of the invention
Below by way of accompanying drawing and implementation step, technical scheme of the present invention is further illustrated
Underground waterproof basic unit of the present invention local emits water source construction method, comprises the steps:
1, the C20 pea gravel concreten block 3 of prefabricated 80mm × 80mm × 80mm, be that the PVC transparent flexible pipe of 8mm passes concrete block 3 as drainage duct 1 is pre-buried using long for 350-400mm internal diameter 1.D, 50mm is stretched out in bottom, and 220-270mm is stretched out on top,
2, find the position at the water source emitting water in basement soil, if emit the similar single column foundation position of water spot, this similar single column foundation waterproof matrix thickeies to 130mm, adds the little heatable adobe sleeping platform 5 of the intensification of profound 80mm × wide 80mm × dark 210mm in this position than former design,
3, steel wire lump 2 being enclosed within drainage duct 1 bottom stretches out on the 50mm of concrete block, after packaging, steel wire lump 2 is downward, together with concrete block 3 and pre-buried drainage duct 1, jointly put into and deepen little heatable adobe sleeping platform 5, the gauze wire cloth 4 of 1000mm × 1000mm is laid centered by the position that this emits water source
4, adopt extruding to catch up with the method for water normally to water and smash basement waterproofing substrate concrete, water when smashing to this position, water nature is emitted upwards to emerge more than 40-90mm concrete surface from the long drainage duct 1 of 350-400mm, and stop is present in concrete surface, this intensification little heatable adobe sleeping platform 5 place concrete surface is reserved 60-90mm and is not deeply watered and smash
If 5, emit the similar single column foundation position of water spot, this similar single column foundation waterproof matrix casting and compacting of concrete must exceed water smash before normally emit water to cut off the water 200mm on elevation location,
6, after normal condition maintenance 10-15 days waterproof matrix concrete reach construction requirement intensity, by drainage duct 1 double flat, use iron wire tighten, can water source be closed,
