Abstract
The utility model relates to the technical field of tunnel construction, in particular to a positioning clamp of a buried water stop belt in tunnel lining; the method is characterized in that: the water-stop rod comprises a rod body, wherein positioning rings are arranged at two ends of the rod body, and a water-stop limiting groove is arranged in the middle of the rod body. The fixing of the buried water stop belt in the annular construction joint of the tunnel is realized by arranging the positioning clamp in the technical content, and the problems that the buried water stop belt in the construction joint is easy to deviate and is difficult to accurately position are solved. The device has effectively ensured two lining construction zhonghuan to bury formula waterstop and has reached anticipated waterproof drainage effect in construction joint department, also is favorable to reducing the rework rate in the tunnel construction simultaneously, improves tunnel waterproof quality for the construction progress reduces construction cost.
Description
Technical Field
The utility model relates to a tunnel construction technical field specifically is a bury locator card of formula waterstop in tunnel lining.
Background
The annular construction joints inevitably appear during the construction of the secondary lining of the tunnel, and the buried water stop belt is usually arranged at the annular construction joints for solving the problem of water prevention and drainage at the construction joints. However, the buried water stop is easy to deviate during the construction of the second liner, so that the buried water stop at the construction joint cannot achieve the effect of water prevention and drainage.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a device that buries formula waterstop off normal in that is arranged in preventing effectively that two adjacent lining sections from encircling to setting up in the construction joint in the tunnel.
In order to achieve the above object, the present invention is realized as follows:
the utility model provides a bury locator card of formula waterstop in tunnel lining, includes the body of rod, the both ends of the body of rod set up the holding ring, set up the waterstop spacing groove at the middle part of the body of rod.
The positioning clamps of the tunnel lining buried water stop belt are used in pairs, and the rod bodies forming the positioning clamps are hung on the two lining main ribs through the positioning rings at the two ends of the rod bodies.
The positioning clamp of the buried water stop belt in the tunnel lining is characterized in that a rod body is formed by bending a twisted steel bar.
The use method of the positioning card comprises the following steps:
and 3, bending for multiple times in the second step to form a convex shape. (ii) a
And 4, binding the steel bars of the die.
Step 5, welding the waterstop positioning clamp device on the position of the double-layer main rib after the step four is finished;
step 6, after the device is installed, installing a buried water stop belt, and placing the water stop belt at the groove of the device;
and 7, setting the distance of the device according to the field condition in the construction process.
The fixing of the buried water stop in the annular construction joint of the tunnel is realized by arranging the positioning card, and the problems that the buried water stop in the construction joint is easy to deviate and difficult to accurately position are solved. The device has effectively ensured two lining construction zhonghuan to bury formula waterstop and has reached anticipated waterproof drainage effect in construction joint department, also is favorable to reducing the rework rate in the tunnel construction simultaneously, improves tunnel waterproof quality for the construction progress reduces construction cost.
Drawings
FIG. 1 is a schematic diagram of the present locator card in use.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1, a locator card of formula of burying waterstop in tunnel lining, including the body of rod 1, the both ends of the body of rod 1 set up holding ring 2, set up waterstop spacing groove 3 in the middle part of the body of rod 1.
The positioning clamps of the tunnel lining buried water stop belt are used in pairs, and a rod body 1 forming the positioning clamps is hung on the two lining main ribs through the positioning rings 2 at the two ends of the rod body.
The positioning clamp of the buried water stop belt in the tunnel lining is characterized in that a rod body 1 is formed by bending a twisted steel bar.
The use method of the positioning card comprises the following steps:
and 3, bending for multiple times in the second step to form a convex shape. (ii) a
And 4, binding the steel bars of the die.
Step 5, welding the waterstop positioning clamp device on the position of the double-layer main rib after the step four is finished;
step 6, after the device is installed, installing a middle-buried water stop, and placing the water stop at the groove 3 of the device;
and 7, setting the distance between the devices according to the field condition in the construction process.
The fixing of the buried water stop in the annular construction joint of the tunnel is realized by arranging the positioning card, and the problems that the buried water stop in the construction joint is easy to deviate and difficult to accurately position are solved. The device has effectively ensured two lining construction zhonghuan to bury formula waterstop and has reached anticipated waterproof drainage effect in construction joint department, also is favorable to reducing the rework rate in the tunnel construction simultaneously, improves tunnel waterproof quality for the construction progress reduces construction cost.
