Description
Technical field
The utility model relates to water sealing structure fields, more particularly, to a kind of replaceable water sealing structure of aqueduct presser type.
Background technique
Aqueduct is the aerial water conveyance structure for conveying ditch water flow across rivers and canals, road, a stretch of flatland in a hilly area, the mouth of a valley etc., is that water conservancy project is built
One of crossing most widely used in object is built, except carrying out field irrigation, urban domestic water, industrial for conveying water in a canal
Outside water, across basin water delivery, draining can also be provided and water conservancy diversion is used, meanwhile, as aqueduct is increasingly increased using shell slot, thin-wall construction
More, the antiseepage problem between expansion joint is consequently increased.The current built generally existing leakage problems of aqueduct expansion joints, analytical table
Bright, expansion joint lose effectiveness in sealing is the first cause for causing aqueduct to leak.Aqueduct expansion joints leak the safe operation for both having influenced aqueduct,
The waste of water resource is caused again, therefore aqueduct expansion joints sealing is most important.
With increasingly developed and new material the extensive use and popularization of science and technology, the type of aqueduct expansion joints patching
Formula and maked rapid progress using material, previous common aqueduct sealing pattern mainly has flush type, bonded type and three kinds of presser type.By
In flush type and bonded type sealing, there are construction qualities to be not easy the defects of guaranteeing, repair and replace difficulty, influences water-stagnating effect.Mesh
Preceding aqueduct sealing mostly uses the replaceable sealing pattern of presser type, by the way that aqueduct expansion joints leakage analysis, sealing leakage is logical
Road mainly has at following three: one, aging rupture causes to leak sealing with age；Two, leakiness shape between sealing and concrete surface
At leakage passage；Three, leakiness forms leakage passage between sealing and pressing plate.In engineering construction operational process, especially lose effectiveness in sealing
Second and third factor usually ignored by people, aqueduct leakage problems usually cannot be solved effectively.
Therefore, these problems are based on, a kind of replaceable pressing plate that effective antiseepage is provided, that durability is high, easy to implement
Formula water sealing structure has important practical significance.

For fixing the stainless steel anchor bolt (band nut and elastic washer) of waterstop and steel plate；
The polysulfide sealant of expansion joint upstream face, waterstop and stainless steel platen end is set；
Polyethylene foam sheet for expansion joint filling；Wherein:
The U-shaped rubber fastening band nose length need to be determining according to aqueduct expansion joints displacement, generally 2~4cm；
" Kan " shape stainless steel platen "-" span access location length is determined according to two rows of pitchs of bolts；It is investigated according to construction material currently on the market
Demonstration, epoxy structural rubber binding material and acrylamide sand grout packing material work well through practical proof, if following have preferably newly
Material can be replaced after practice demonstration and be used.
Water stopping trough basal plane carries out leveling using acrylamide sand grout, and dog-ear position reinforces thickness and forms arcuation, stainless steel pressure
Plate encounters arc position by building surface radian pre-bending.
After having brushed epoxy structural rubber, it is desirable that be laid with rubber fastening band and bonding stainless steel steel under the non-curdled appearance of structure glue
Plate, and to reach two sides and have colloid spilling.
In order to reinforce fastening force, if two rows of stainless steel bolts, pitch of bolts are generally 5cm, diameter 12mm, length is
10cm。
The utility model implementation steps are as follows: step 1: reserving groove, pre-buried 2 row stainless steel bolt, bolt on concrete
Diameter 12mm, spacing 5cm；Step 2: water stopping trough basal plane carries out leveling, dog-ear using the compound tough type acrylamide sand grout of polymer
Position reinforces thickness and forms arcuation, and the compound tough levelling thickness of type acrylamide sand grout of polymer is controlled according to live flatness；Step 3:
It is punched on U-shaped waterstop in advance, the size and spacing in hole are consistent with the size of water stopping trough inner bolt and spacing.Water stopping trough is levelling
Afterwards, in water stopping trough basal plane brush epoxy structural rubber, glue-line thickness is not less than 3mm, it is desirable that smear it is uniform and smooth, epoxy structural rubber not
