Description

Local structure that reduces of basement roof

Technical Field

The application relates to the technical field of constructional engineering structures, in particular to a local structure that reduces of basement roof.

Background

In the middle of the building engineering, some areas belong to dead weight collapsible loess, and dead weight collapsible loess meets water and easily takes place the liquefaction and loses the bearing capacity, leads to the structure to collapse. According to relevant regulations, all water supply and drainage pipelines are arranged in a leakage detection pipe ditch within 7 meters around a building so as to be convenient for regular inspection and avoid the phenomenon that the leakage cannot be found in time to cause the liquefaction of soil to lose bearing capacity and endanger the main structure. Therefore, in the basement roof area where the water supply and drainage pipeline passes through, the thickness of the covering soil needs to reach a certain depth so as to meet the setting requirement of the pipe ditch. Originally, set up the trench in the region that earthing thickness can not reach appointed degree of depth, the method of adoption is that deepening the whole excavation depth of basement, nevertheless, deepening the whole excavation depth of basement can cause the increase by a wide margin of engineering cost.

To the above problem, a local reduction structure of a basement roof is proposed.

SUMMERY OF THE UTILITY MODEL

In order to avoid deepening the condition of the whole excavation depth of basement because of establishing the leak hunting trench, this application provides a local structure that reduces of basement roof.

The application provides a local structure that reduces of basement roof adopts following scheme:

the utility model provides a local structure that reduces of basement roof, includes horizontal roof, the top distribution of horizontal roof has the leak hunting trench, the leak hunting trench extends outside the region directly over the horizontal roof, be provided with the recessed reduction portion of whole on the horizontal roof, the leak hunting trench distribute in the part directly over the horizontal roof all is located directly over the reduction portion.

By adopting the scheme, the mode that the top plate of the basement is locally reduced is adopted, and the deepening of the integral excavation depth of the basement is avoided on the premise that the thickness of the local covering soil at the periphery of the building meets the requirement of pipe ditch setting.

The application is further configured to: and water baffles which are hermetically connected to the horizontal top plate are arranged on two sides of the reducing part.

Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses local structure that reduces of basement roof.

Example 1: as shown in fig. 1, the underground leakage detection device comprises a horizontal top plate 1 at the top of a basement, a leakage detection pipe ditch 2 is arranged above the horizontal top plate 1, a water supply and drainage pipe is arranged in the leakage detection pipe ditch 2, and the leakage detection pipe slightly inclines and extends downwards and extends out of the range right above the horizontal top plate 1; the setting of leak hunting pipeline can lead to the actual earthing thickness of horizontal roof 1 top to descend, in order to satisfy earthing thickness's requirement, set up whole recessed reduction portion 3 on horizontal roof 1, reduction portion 3 is the regional whole reduction of horizontal roof 1, namely the cross-section of some horizontal roof 1 is the U font and sets up and is less than the remaining part of horizontal roof 1, this cross-section is the part of U font and extends to the opposite side from one side of horizontal roof 1, the part that leak hunting ditch 2 is located directly over horizontal roof 1 all is located reduction portion 3 directly over, thereby make the actual earthing thickness directly over reduction portion 3 meet the requirements, and unlikely to lead to actual earthing thickness to not meet the requirements after setting up leak hunting ditch 2.

The leakage detecting pipe channel 2 is arranged above the reducing part 3, so that the bearing weight of the top plate of the reducing part 3 is heavier than that of the rest part of the horizontal top plate 1; the lowering part 3 is in a groove shape, and the top surface of the lowering part 3 is lower than the top surface of the other part of the horizontal top plate 1, so that water outside the lowering part 3 easily flows into the lowering part 3, and the load of the top plate of the lowering part 3 is further increased; in order to avoid the water on the upper surface of the rest part of the horizontal top plate 1 to flow into the reducing part 3, the water baffle plates 4 are arranged on the two sides of the reducing part 3, the water baffle plates 4 are vertically arranged, the lower sides of the water baffle plates 4 are hermetically connected onto the horizontal top plate 1, the water baffle plates 4 are arranged on the two sides of the 3U-shaped cross section of the reducing part, the water baffle plates 4 are arranged along the extending direction of the reducing part 3, the water baffle plates 4 can block the water on the upper surface of the horizontal top plate 1, and the water is prevented from flowing into the reducing part 3.

Although the water baffle 4 is provided to block the water on both sides of the lowering part 3, the water is also leaked from above the lowering part 3, so that the upper surface of the top plate of the lowering part 3 is set to be an inclined surface with one side higher and the other side lower, and the inclined surface is arranged to enable the water on the upper surface of the top plate of the lowering part 3 to be more easily discharged out of the upper surface area of the top plate, thereby reducing the accumulated water and reducing the load of the top plate of the lowering part 3.

In addition, the distributed support columns 10 are arranged below the top plate of the reducing part 3, and the upper ends of the support columns 10 support the top plate of the reducing part 3, so that the bearing capacity of the top plate of the reducing part 3 is improved.

Although leak hunting trench 2 can detect water supply and drainage pipe's damaged seepage, when the loess liquefaction of leak hunting trench 2 below, leak hunting trench 2 can sink, and water supply and drainage pipe in the leak hunting trench 2 bends thereupon down, causes the pipeline to damage easily, in order to avoid this condition, has still set up support frame 5 between leak hunting trench 2 and the 3 tops of reduction portion in order to support leak hunting trench 2 for leak hunting trench 2 is difficult for sinking.

The supporting frames 5 are provided in plurality and arranged at intervals along the extending direction of the leak detection pipe channel 2. Support frame 5 is including supporting upper plate 6 and supporting hypoplastron 7, support upper plate 6 and support through vertical intermediate link 8 fixed connection between the hypoplastron 7, support upper plate 6 and laminate in the lower surface of leak hunting ditch 2, and at the upper surface both sides fixedly connected with gag lever post 9 that supports upper plate 6, when supporting upper plate 6 and supporting leak hunting ditch 2, gag lever post 9 carries on spacingly to leak hunting ditch 2, avoid leak hunting ditch 2 to take place the skew, support hypoplastron 7 then to laminate in the roof upper surface of reduction part 3.

Example 2: as shown in fig. 2, the present embodiment differs from embodiment 1 in that the depressed portion 3 is not depressed over the entire area, but only a portion located directly below the leak pipe 2 is depressed, and the width of the leak pipe 2 is large, and how wide the depressed area of the depressed portion 3 is provided.

The specific embodiments are only for explaining the present application and are not limiting to the present application, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the claims of the present application.
