Description

The scarfing type waterproof roll

Technical field

The utility model content belongs to underground structure waterproofing protection technical field, relates to a kind of waterproof roll that can be used for tunnel, water construction thing.

Background technology

Underground structrue engineering waterproof construction in the past is example with the housing basement; be earlier with coiled material coating class waterproofing materials is pasted or brushing on the plain concrete bed course of building foundation bottom; on waterproofing materials, do one deck pea gravel concreten topping then, on top put the concrete of bar pouring underpin at last again.Because concrete mats is on the soil layer, be positioned at below the groundwater table mostly again, under the unbalanced pressure of top-out, sedimentation, flexural deformation can take place in building foundation, even can be at some positions because serious sedimentation is uneven the cracking that occurs fractureing, and the soil layer that is soaked in the water also can the deliquescing depression, so concrete cushion will inevitably fracture in this case, break thereupon, this also just makes waterproofing course attached thereto also damage and water inflow must occur, in case and waterproofing course has place water inlet, then whole basis will be among the underground bubble.

" the past people think that always concrete is permanent material, but recognize gradually that by putting into practice people concrete can be subjected to phreatic erosion in underground construction, and its durability can be affected.Now particularly the damage ratio that is subjected to of phreatic water is more serious for China's underground water, and the transmission coefficient of waterproof concrete when impervious grade S8 is 5～8 * 10 ^-8Cm/s is so underground water is a problem that can not be ignored to the erosion damage of concrete, reinforcing bar " (drawing) from " underground waterproof engineering inspection of quality standard ", this also is the ubiquitous thorny problem in waterproof field, underground building both at home and abroad at present.

Existing underground structure waterproof roll generally adopts one or both material one to be processed into, though the item a great variety of material, but quality is very different, in addition since at present people to the importance of waterproofing materials quality at a specified future date and and construction cost between the deficiency of correlation understanding aspect, easily be out of shape and draw up many problem and hidden danger such as infiltration, corrosion resistance be unreliable to such an extent as to the underground building that utilizes existing well known materials to do waterproofing work exists material itself with concrete component.When in a single day above problem and hidden danger occur, construction party again desire building is done waterproof repairment or overhauled will be very difficult all, it not only has influence on the normal operation of subsurface equipment, more need with the above backfill of base concrete dig up and subregion search repairing, also need the arrestment operation when serious, reform trench even generation equipment is torn open to move once more and is installed, and time-consuming, its renewal expense generally all will be on the several times of first waterproof construction cost.

The utility model content

The purpose of this utility model is to overcome the weak point that prior art exists, so a kind of rational in infrastructure, easy construction is provided, the cost cost is low, tensile strength is high, water resistance is good and the scarfing type waterproof roll of long service life.

The technical solution that adopts is so for achieving the above object: the scarfing type waterproof roll that is provided has the waterproof base material bed course that one deck is made by modified PE class plastics macromolecular material, on waterproof base material bed course, be covered with the grid made from the vertical waterproof rib in length and breadth of material system, be equipped with the protruding grain of embedding connection of evagination at each waterproof rib grid line commissure point place of described grid.

Compared with prior art; the utility model is at the problem crux of ago descending waterproofing course to be easy to lose efficacy; by covering waterproof rib grid at the collision mat laminar surface and adhering to the protruding grain of embedding connection; can directly on coiled material, put the bar pouring concrete; thereby make it and basis, the top co-operation that combines as a whole; this just has been completely free of the relation and the influence of waterproofing course and following bed course; thereby can adapt to building foundation under various sedimentations cracking distortion and adapt to the corrosion of various harmful components in the underground water; can effectively protect the harm of reinforced concrete member corrosion; improve the length of service of waterproofing materials; and then the application life of prolongation building. in addition; the utility model is owing to covered and can join protruding grain with waterproof rib grid and the embedding that bed course is combined closely at the collision mat laminar surface; increased the tension of waterproof roll; the pliability of compressive strength and material itself; can adapt to construction period top tramples; put construction weight and influences such as reinforcing bar; convenient construction is produced. the scarfing type waterproof roll can also according to engineering-environment such as resistance to compression; tension is carried out calculation Design with different requirements such as elastic extension indexs; produce the building underground construction; roofworks; construction of tunnel and different use products such as hydraulic engineering; can use at basic plane; also can use at external wall elevation; thereby waterproofing can be placed controlled; in the effective range of determining; fundamentally solve the waterproofing problem with regard to being expected to like this. along with the continuous appearance of the more excellent new material of performance; utilize this technology can produce excellent more waterproof roll; constantly promote waterproof safety with this; engineering waterproofing design and construction are become initiatively accurately form from passive extensive form, thereby have obtained huge social benefit and economic benefit.
