Description

The traditional assembled canal has the problems of more assembling gaps, poor water sealing effect of joints, serious water leakage and poor durability, and the traditional assembling joint water sealing structure is also unreasonable.

And the other assembly joints are directly filled with concrete to fill the side wall grooves to serve as a water stop structure, and once a rigid concrete material is selected to serve as water stop, the rigid material is easy to crack, so that cracks are generated between the side wall components and the filled concrete, and water leakage and water seepage occur. Some fill the sealant in the shallow degree of depth in side wall assembly seam surface and act as the stagnant water structure, this kind of structure is comparatively simple and easy, and the stagnant water effect is not good. And water-swelling rubber strips or asphalt hemp threads are filled in the depth with shallower side wall assembly seam surface to serve as a water stopping structure.

The traditional assembly joint water stopping structures only consider unilateral water stopping effect, but do not consider the structural effect of preventing dislocation deformation of the assembly joints. That is, two adjacent side wall components have no connecting structure or unreasonable and unreliable connecting structure, have poor overall performance, and can cause dislocation deformation of the side wall components under the influence of temperature change stress, foundation settlement deformation or other external force, and the settlement deformation or the temperature deformation can generate gaps in the side wall grooves; the splice gap changes to cause the water-stopping gap to bulge, crack and deform, water-stopping failure generates water leakage and water seepage, so that the normal use of the canal is affected, and the service life of the canal is also reduced.

On the basis, a water stop and dislocation deformation prevention structure for the side wall joint of the bottom-first and wall-last assembled trench is provided.

A water stop column 42, a caulking plate 43 and an dislocation-preventing deformation column 44 are respectively and correspondingly arranged in the water stop cavity 10, the caulking plate cavity 11 and the dislocation-preventing deformation cavity 12.

Water stop column 42: the water stopping column 42 is arranged in the water stopping cavity 10, and the water stopping column 42 is a column filled with asphalt caulking ointment, as shown in fig. 5. Specifically, the water-stopping cavity 10 is filled with asphalt caulking ointment water-stopping materials, namely, the fully boiled asphalt caulking ointment is filled into the water-stopping cavity 10 from bottom to top to be filled tightly, so that a water-stopping column 42 is formed, and a water-stopping effect is achieved.

The asphalt caulking ointment is a cold waterproof joint material prepared by mixing petroleum asphalt as a base material, a modified material and a filler, and can be used for cold construction at the temperature of 15 ℃; can keep good flexibility and plasticity and does not crack under the condition of the temperature of minus 20 ℃; no flow and drop occurs under the condition of the temperature below 70 ℃; can be firmly bonded with most materials; the waterproof performance is good, and the water is not absorbed; the elasticity and the ductility are good; stable and reliable performance, difficult aging and durability.

The asphalt caulking ointment has good water resistance, adhesiveness and aging resistance, and the adhesive property of the asphalt caulking ointment enables the asphalt caulking ointment to be well adhered to the concrete surface in the water-stopping cavity 10, so that the asphalt caulking ointment can block the water-permeable and water-permeable channels of the assembled seams to achieve the water-stopping effect. The cross-shaped water-stopping cavity 10 increases the bonding area between the asphalt caulking ointment and the concrete surface, and enhances the blocking and water permeation blocking capabilities.

Because the combination of the side wall water-stop groove 6 and the water-stop caulking ointment is tightly attached by the coupling structure, when the side wall assembly seam gap is staggered or enlarged left and right, the water-stop caulking ointment is pulled to ensure that the contact surface of the ointment and the water-stop groove 6 is pulled more tightly, so that the water-stop effect is not reduced, and the water-stop requirement is met; when the left and right dislocation or shrinkage of the split joint gap of the side wall is realized, the water-stopping caulking ointment is extruded to ensure that the contact surfaces between the ointment and the two sides of the side wall groove and the bottom edge of the groove are more compact, so that the water-stopping effect is not reduced and the water-stopping requirement is met.

Caulking plate 43: the caulking plate 43 is arranged in the caulking plate cavity 11, the caulking plate 43 is a long slat made of wood board or hard plastic board, namely, the caulking plate 43 can be made of wood board or hard plastic board. The width of the caulking plate 43 is the sum of the width of the vertical assembly seam 3 of two adjacent side wall components 2 and the depth of the caulking plate grooves 7 of the two side wall components 2 minus 10mm gap, namely, the width of the caulking plate 43 is 15+30+30-10=75mm, the thickness of the caulking plate 43 is 10mm, the length of the caulking plate is 4.6m, in short, the caulking plate 43 can shake in the cavity 11 of the caulking plate to a certain extent, and the subsequent extraction of the caulking plate 43 can be facilitated.

The caulking plate 43 plays a role in separating the water stop column 42 and the dislocation deformation prevention column 44, and has shaking but does not affect the plugging; the caulking plate 43 is inserted in the middle of the cavity 11 of the caulking plate to block the channel of the vertical assembly seam 3. When the water stop column 42 is constructed first, the caulking plate 43 is pressed to be offset to one side of the dislocation preventing deformation cavity 12, whereas when the dislocation preventing deformation column 44 is constructed first, the caulking plate 43 is pressed to be offset to one side of the water stop cavity 10, and the caulking plate 43 can block the vertical assembly joint 3 no matter which side is offset.

The caulking plate 43 can prevent concrete slurry from entering the water stop cavity 10 through the vertical assembly joint 3 during the concrete pouring of the dislocation preventing deformation cavity 12 so as to avoid occupying the space of the water stop cavity 10, ensure enough space of asphalt caulking ointment, and can be reused after the concrete pouring of the dislocation preventing deformation cavity 12 is completed and solidified.

When the micro-expansion fine stone concrete is poured, construction is carried out from bottom to top, the micro-expansion fine stone concrete is tightly filled with the dislocation deformation preventing cavity 12 after pouring, and the micro-expansion of the micro-expansion fine stone concrete enables the fine stone concrete to be tightly connected with the dislocation deformation preventing cavity 12, so that the effect of preventing the water leakage of the canal can be achieved. The micro-expansion fine stone concrete forms the action of a plug column in the dislocation deformation prevention cavity 12, and tightly plugs the gaps of the dislocation deformation prevention cavities 12 of two adjacent side wall members 2, so that the two side wall members 2 are connected into a whole, and the plug column, namely the dislocation deformation prevention column 44, plays a role in preventing the side wall members 2 from dislocation deformation left and right, ensures the integrity of a canal, further ensures that the water-stopping asphalt caulking ointment cannot generate dislocation deformation, further ensures the water-stopping effect and achieves the water-stopping aim.
