Wherein the stagnant water groove is mostly prefabricated concrete structure, and the sealing rod is mostly the EPT rubber material, leans on high-strength glue to connect between the two, exists the multiple not enough with the operation period during the construction. For example: during construction, a water stopping groove area of a precast concrete structure is often collided, concrete at the position of the water stopping groove cracks and even falls off, so that the shape of the water stopping groove is incomplete, and the water stopping effect is directly influenced; during construction, particularly during installation, the water stop strip is frequently rubbed and bumped, the water stop strip is connected with the water stop groove only by glue, the water stop strip is easy to fall off, the water stop strip directly causes waterproof failure of an underground structure after falling off, the glue is gradually aged and failed during operation, the water stop groove connected by the glue is directly disconnected with the water stop strip, the waterproof failure is caused, and the underground structure is unstable and collapsed in severe cases; in the conventional arrangement, the water stopping tank is made of concrete, and is easy to generate through cracks, further form a water channel and cause groundwater leakage.
The water stopping technology of the prefabricated structure has one or more defects, such as high cost, difficult installation, long construction period, poor water resistance and poor seepage resistance. Therefore, there is a need in the engineering industry to find a new water stopping tank structure that can replace and overcome the above drawbacks, but the current industrial dilemma is not solved well.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that there are the difficult, waterproof poor, the poor problem of prevention of seepage of installation in overcoming current prefabricated construction stagnant water technique, provide a novel stagnant water groove. In order to achieve the above purpose, the utility model adopts the technical scheme that:
the water stopping groove comprises a water stopping groove main body and water stopping strips matched with the water stopping groove main body, and is characterized in that side plates are arranged on two sides of the water stopping groove main body respectively, water stopping groove anti-seepage plates are arranged on two sides of the water stopping groove main body respectively, and holes for fixedly connecting the water stopping groove main body and the water stopping strips are formed in the positions, corresponding to the water stopping groove main body and the water stopping strips.
Preferably, the water stopping groove side plates on the two sides of the water stopping groove main body are different in inclination angle, and the angle value range of the inclination angle is 65-75 degrees. And a water stopping groove anchoring rib is fixed outside the water stopping groove main body.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1. the utility model has good operability;
2. the connection quality of the components is reliable;
3. the waterproof and anti-seepage performance is good;

Detailed Description
The following detailed description of the present invention will be made with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
The present invention will now be further described with reference to the drawings.
As shown in fig. 1-3, during considering underground structure construction and operation, the utility model provides a novel stagnant water groove structure, wherein contain prefabricated stagnant water groove main part 1, this part is formed by the preparation of steel member, steel thickness is 3mm, stagnant water groove bottom plate 11 width is 40mm, according to the research result of this subject group, the higher area that groundwater pressure is great promptly of moisture content, the different design of slope of both sides stagnant water groove curb plate 13 can make the obvious increase of joint water-proof effects, and the optimum angle scope is 65 ~ 75, so the utility model relates to a stagnant water groove curb plate 13 left side is 65, and the right side is 75, and adjacent stagnant water groove staggers at the angle of homonymy during the use to can increase stability. The size design of the prefabricated water stop tank main body 1 corresponds to the size of a common water stop strip, is not limited to the case, and can determine the size suitable for actual project engineering according to actual engineering and construction site conditions.
Meanwhile, considering that the contact part of the prefabricated water-stopping groove main body 1 and the concrete member 5 generates water leakage, a water-stopping groove anti-seepage plate 14 which is inclined downwards by 45 degrees is arranged at the junction of the water-stopping groove bottom plate 11 and the water-stopping groove side plate 13, the design can prevent the water leakage at the joint of the prefabricated water-stopping groove main body 1 and the concrete member 5, and meanwhile, the prefabricated water-stopping groove main body 1 can be tightly fixed on the concrete member 5, so that the displacement deformation during construction or operation is effectively prevented.
In order to fix prefabricated stagnant water groove main part 1 on concrete member 5, can not take place to drop, set up stagnant water groove anchor muscle 15, anchor length is 50mm, and the material is the smooth round steel muscle of diameter for 4mm to set up at the top and buckle, buckle length and accord with relevant standard requirement, the present case is buckled and is set up to the right angle, but not only is the right angle, has multiple mode of buckling.
Be provided with at one section distance of stagnant water groove bottom plate 11 and reserve bolt hole 12, with sealing rod 2, cross bolt 3, sealing plug 4 simultaneous working, guarantee the stagnant water and the anti-drop effect of this patent. The size of the reserved bolt hole 12 corresponds to the size of the cross bolt 3, and the diameter of the reserved bolt hole is 4mm in the embodiment.
As shown in fig. 4, the water stop strip 2 is composed of a water stop strip main body 21 and a water stop strip preformed hole 22, wherein the external dimension of the water stop strip main body 21 corresponds to the prefabricated water stop tank main body 1, the water stop strip preformed hole 22 reserved on the water stop strip main body 21 will accommodate the cross bolt 3 and the sealing plug 4, and the cross-sectional shape of the water stop strip preformed hole 22 is as shown in fig. 2.
