Abstract
The utility model provides a settlement joint structure of an underground hydraulic structure. A concrete cushion layer is arranged below the underground hydraulic structure. The settlement joint structure is characterized by comprising a plurality of sleepers arranged below the concrete cushion layer, wherein the plurality of sleepers are arranged at intervals along a settlement joint; the settlement joint is positioned in the center of the sleepers; and graded broken stones are filled between adjacent sleepers. The settlement joint structure has the advantages that: (1) the construction efficiency is high, and the quality is high; (2) the construction is simple and convenient, and is simple and easy to implement; (3) the stress between adjacent plates of the settlement joint of the structure can be reduced, settlement deformation is prevented, and the engineering quality is ensured; and (4) the later maintenance cost is reduced, the settlement position is about 300 yuan/workday *2 days *5 persons, the material is saved by 3,000 yuan, and the total maintenance cost is 6,000 yuan.
Description
Technical Field
The utility model relates to an underground hydraulic structure subsiding crack handles technical field, concretely relates to underground hydraulic structure subsiding crack structure.
Background
With the continuous improvement of municipal infrastructure, underground structures are generally applied to town construction, and due to the problems of structural design, material selection, construction process and the like, the durability of the underground structures cannot meet the use requirement, so that the use function is influenced, and potential safety hazards exist. Through market research, it is found that leakage easily occurs at deformation joints, construction joints, post-cast strips, wall pipes (boxes), embedded parts and other parts of structures, and the concrete results are as follows:
1. the stress deformation at the settlement joint is large, and adjacent plates are easy to misplace;
2. the water stop belt at the deformation joint is not firmly fixed, and the water stop belt is easily damaged during concrete pouring and vibrating construction;
3. the water-stopping steel plate at the construction joint is not installed normally, positioned inaccurately and welded in place;
4. the joint surface of new and old concrete at the post-cast strip is not processed in place; the end of the full-length water stop screw rod is not blocked in place;
5. the traditional template has the defects of loose abutted seams and large deformation, and is easy to cause the honeycomb pitted surface on the surface of concrete.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defect that the stress deformation of the settlement joint is large and the adjacent plates are easy to be dislocated, the utility model provides a settlement joint structure of an underground hydraulic building.
In order to solve the above problems, the utility model is realized according to the following technical scheme.
A settlement joint structure of an underground hydraulic structure is characterized in that a concrete cushion layer is arranged below the underground hydraulic structure and comprises a plurality of sleepers arranged below the concrete cushion layer, the sleepers are arranged at intervals along the settlement joint, the settlement joint is positioned in the center of each sleeper, and graded broken stones are filled between every two adjacent sleepers.
Further, the height of the graded broken stone is 150 mm.
Further, the spacing between adjacent sleepers is 1000 mm.
Further, the specification of the sleeper is 2000 × 150 × 200 mm.
Furthermore, a tarragon anticorrosive layer is arranged on the outer side of the sleeper.
Has the advantages that: (1) high construction efficiency and good quality.
(2) The construction is simple, the bottom is simply handed over, and the operation is easy.
(3) The stress between adjacent plate blocks of the settlement joint of the structure can be reduced, the settlement deformation is prevented, and the engineering quality is ensured.
(4) The later maintenance cost is reduced, each settlement position is about 300 yuan/work day 2 days 5 yuan 3000 yuan, 3000 yuan is saved in materials, and the total maintenance cost is 6000 yuan.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-underground hydraulic structures; 2. a concrete cushion layer; 3. crossties; 4. grading broken stone.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in fig. 1, a C15 concrete cushion layer 2 is arranged below an underground hydraulic structure 1 made of C30 concrete. The middle part and the two ends of the underground hydraulic structure 1 are respectively provided with a settlement joint. And a plurality of sleepers 3 are arranged below the concrete cushion layer 2 at intervals along each settlement joint. The sleeper 3 is placed with the settlement joint as the center line.
The sleeper 3 is made of anticorrosive wood and is installed according with the design elevation. And (3) carrying out asphalt preservative treatment on the sleeper 3 when entering the field. The horizontal deviation of the sleeper 3 is not more than 50mm, and the height deviation is not more than 10 mm. Distance between sleepers: 1000mm, sleeper pitch deviation: plus or minus 50mm, sleeper specification: 2000X 150X 200mm, 150mm graded broken stone is laid between sleepers.
The utility model relates to a process flow includes: 1) material approach inspection; 2) paying off and positioning; 3) installing a sleeper; 4) leveling a broken stone cushion layer; 5) checking and accepting.
Claims (5)
1. The utility model provides an underground hydraulic structure subsiding crack structure, underground hydraulic structure below is the concrete bed course, its characterized in that, including setting up a plurality of sleeper in concrete bed course below, a plurality of sleeper sets up along subsiding crack interval, and the subsiding crack is located the center of sleeper, and it has the graded rubble to fill between the adjacent sleeper.
2. The underground hydraulic structure of claim 1, wherein the graded crushed stone has a height of 150 mm.
