Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a structure for connecting buildings and pipe trenches and a nuclear power plant building. Background Technology

[0002] At the connection point between the building / structure and the pipe trench, the building / structure generally has a solid foundation and can be considered as a whole without settlement. However, the base of the pipe trench, which is close to the building / structure, is backfill soil, which is prone to settlement. This will create a large settlement difference between the pipe trench and the building / structure, resulting in a large amount of settlement deformation on the pipe trench side at the connection point. This large amount of settlement deformation can cause the waterstop between the building / structure and the pipe trench interface to break, causing the waterstop between the building / structure and the pipe trench interface to lose its waterproofing performance.

[0003] Therefore, how to reduce the deformation between the building structure and the pipe trench is a technical problem that needs to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned deficiencies in the existing technology by providing a connection structure between a building and a pipe trench, as well as a nuclear power plant building, which can reduce the settlement at the interface end of the pipe trench, thereby reducing the deformation between the interface end of the building and the pipe trench.

[0005] In a first aspect, this utility model provides a structure connecting a building and a pipe trench, the structure comprising a building and a pipe trench. A support portion is provided on the side of the building, the support portion being used to support the interface end of the pipe trench. The interface end of the pipe trench is disposed on the support portion and is movably connected to the building.

[0006] In some embodiments, a first elastic buffer material is provided between the top surface of the support and the bottom surface of the trench.

[0007] In some embodiments, the top surface of the support is divided into a planar portion and an inclined portion in the direction from the structure to the trench, with the inclined portion sloping downwards.

[0008] In some embodiments, the support extends along the width direction of the trench, and the size of the support is larger than the width of the trench interface end in the width direction of the trench.

[0009] In some embodiments, a retaining wall is also provided at the trench interface on the side of the building; there are two retaining walls, both of which are vertically arranged and respectively located on both sides of the trench, for limiting the deflection direction of the trench to the vertical direction when the trench settles.

[0010] In some embodiments, a second elastic buffer material is provided between the interface end of the retaining wall and the trench.

[0011] In some embodiments, both the support and the retaining wall extend out of the structure, and the two ends of the support are connected to the bottom of the two retaining walls as a single unit.

[0012] In some embodiments, an expansion joint is provided between the interface end of the trench and the side of the building.

[0013] In some embodiments, the interface end of the trench is movably and sealed to the side of the building structure by a first waterstop, which is disposed in the expansion joint.

[0014] Therefore, the structure connecting the building and the trench provided in this embodiment of the utility model can support the interface end of the trench by setting a support part on the side of the building; by making the interface end of the trench movably connected to the building, the trench can settle normally relative to the building; by setting the interface end of the trench on the support part, the support part can support the interface end of the trench when the trench settles, thereby reducing the amount of deformation between the interface end of the trench and the building, and preventing the waterstop between the building and the trench from being torn off due to excessive deformation and losing its waterproof performance.

[0015] Secondly, this utility model embodiment also provides a nuclear power plant building, which includes buildings and trenches, and the connection between the buildings and trenches forms the building-trenches connection structure in the first aspect.

[0016] The aforementioned nuclear power plant building has the same beneficial technical effects as the building structures and trench connection structures provided in some of the above embodiments, and will not be repeated here. Attached Figure Description

Based on the embodiments provided by this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

[0027] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the regions of the structure, nor are they intended to limit the scope of the exemplary embodiments.

[0028] Example 1:

[0029] like Figure 1 and Figure 2As shown, this utility model embodiment provides a structure for connecting buildings and pipe trenches. The structure is applied in building structures to connect buildings and pipe trenches.

[0030] like Figure 1 As shown, the connection structure between the building and the pipe trench includes the building 1 and the pipe trench 3. A support 2 is provided on the side of the building 1, which is used to support the interface end of the pipe trench 3. The interface end of the pipe trench 3 is located on the support 2 and is movably connected to the building 1.

[0031] For example, the structure 1 is generally a solid foundation and can be considered as a whole that does not settle, that is, the position of the structure 1 remains unchanged. The support 2 can be a part of the structure 1, and the position of the support 2 can also be considered as remaining unchanged.

[0032] The dimensions of support 2 can be set according to site conditions and work experience.

[0033] For example, such as Figure 1 and Figure 2 As shown, the side of the structure 1 is a vertical plane, the support part 2 extends out of the side of the structure 1, and the trench 3 extends in the horizontal direction.

[0034] After the interface end of the pipe trench 3 is installed on the support part 2, the support part 2 can support the interface end of the pipe trench 3 in the vertical direction. The interface end of the pipe trench 3 is movably connected to the structure 1, which allows the relative position between the interface end of the pipe trench 3 and the structure 1 to change, so that the pipe trench 3 can settle normally.

[0035] like Figure 1 As shown, Figure 1 When trench 3 in the middle settles, because the interface end of trench 3 ( Figure 1 The left side of the central trench 3 is supported by the support part 2, so the bottom position of the interface end of the trench 3 can be considered to remain unchanged, that is, the interface end of the trench 3 basically does not settle relative to the structure 1; and Figure 1 The right side of trench 3 settled downwards normally, causing trench 3 to tilt. The final position of trench 3 after settlement became... Figure 1 The position of the dotted line in the text.

[0036] Therefore, after the support part 2 is installed, the settlement of the interface end of the pipe trench 3 can be reduced when the pipe trench 3 settles, thereby reducing the deformation between the interface end of the pipe trench 3 and the building 1, and preventing the waterstop between the building 1 and the pipe trench 3 from being broken due to excessive deformation and losing its waterproof performance.

[0037] Therefore, the structure connecting the building and the trench provided in this embodiment of the utility model, by providing a support part 2 on the side of the building 1, can support the interface end of the trench 3; by making the interface end of the trench 3 movably connected to the building 1, the trench 3 can settle normally relative to the building 1; by setting the interface end of the trench 3 on the support part 2, when the trench 3 settles, the support part 2 can support the interface end of the trench 3, thereby reducing the amount of deformation between the interface end of the trench 3 and the building 1, and preventing the waterstop between the building 1 and the trench 3 from being torn off due to excessive deformation and losing its waterproof performance.

[0038] In some embodiments, combined with Figure 1 and Figure 3 A first elastic buffer material 4 is provided between the top surface of the support part 2 and the bottom surface of the trench 3.

[0039] For example, the first elastic cushioning material 4 can be a flexible material such as polystyrene board. The thickness of the first elastic cushioning material 4 can be 3 mm.

[0040] The first elastic buffer material 4 can buffer the force between the top surface of the support part 2 and the bottom surface of the trench 3 when the interface end of the trench 3 deforms, thus preventing the force from being too large and causing damage to the structure of the support part 2 and the trench 3.

[0041] In some embodiments, combined with Figure 1 and Figure 3 From the direction of the structure 1 towards the trench 3, the top surface of the support part 2 is divided into a flat part M1 and an inclined part M2, with the inclined part M2 tilting downwards.

[0042] For example, the inclination angle of the inclined section M2 can be set according to work experience so that the inclination angle of the inclined section M2 is approximately the same as the inclination angle of the trench 3 after settlement.

[0043] like Figure 1 and Figure 3 As shown, the planar part M1 can support the interface end of the trench 3 when the trench 3 has not settled. When the trench 3 settles and tilts, the gap between the inclined part M2 and the trench 3 can form a deformation space when the trench 3 tilts, thus preventing the trench 3 from being squeezed at the end point of the top surface of the support part 2 when the trench 3 tilts after settling, which would damage the structure of the support part 2.

[0044] In some embodiments, such as Figure 2 As shown, the support part 2 extends along the width direction of the trench 3, and the size of the support part 2 is larger than the width of the interface end of the trench 3 in the width direction of the trench 3.

[0045] With the above configuration, the support part 2 can support the entire interface end of the trench 3 in the width direction, thereby improving the support effect on the interface end of the trench 3.

[0046] In some embodiments, such as Figure 2 As shown, a retaining wall 5 is also installed at the interface of the pipe trench 3 on the side of the structure 1. There are two retaining walls 5, both of which are vertically installed and are respectively installed on both sides of the pipe trench 3, in order to limit the deflection direction of the pipe trench 3 to the vertical direction when the pipe trench 3 settles.

[0047] For example, retaining wall 5 can be part of structure 1.

[0048] Through the above settings, combined with Figure 2 This allows the deflection direction of trench 3 to be limited to the vertical direction when settlement occurs, preventing settlement along the width direction of trench 3 (i.e., ...) Figure 2 It shifts in the vertical direction and slides off the support 2.

[0049] In some embodiments, a second elastic buffer material is provided between the interface ends of the retaining wall 5 and the trench 3.

[0050] For example, a second elastic buffer material is provided between the interface ends of the two retaining walls 5 and the trench 3. The second elastic buffer material can be a flexible material such as polystyrene board. The thickness of the second elastic buffer material can be 3mm.

[0051] In some embodiments, such as Figure 2 As shown, both the support part 2 and the retaining wall 5 extend out of the structure 1, and the two ends of the support part 2 are connected to the bottom of the two retaining walls 5 as a whole.

[0052] For example, the dimensions of the support 2 and the retaining wall 5 extending out of the structure 1 can be set according to the site conditions and work experience.

[0053] The above-mentioned configuration can improve the structural strength of the support 2 and the retaining wall 5, and enable the support 2 and the retaining wall 5 to be constructed simultaneously, thereby reducing the construction difficulty of the support 2 and the retaining wall 5.

[0054] In some embodiments, such as Figure 1 and Figure 3 As shown, there is an expansion joint between the interface end of the trench 3 and the side of the structure 1.

[0055] The size of the expansion joint can be set according to the site conditions and work experience.

[0056] like Figure 1As shown, by setting up expansion joints, the relative displacement between the interface end of the trench 3 and the building 1 can be absorbed, thus preventing the trench 3 from directly colliding with the building 1 and causing structural damage when the trench 3 settles.

[0057] In some embodiments, the interface end of the trench 3 is movably and sealed to the side of the building 1 by a first waterstop 7, which is provided in the expansion joint.

[0058] For example, the first waterstop 7 is an embedded waterstop, and the embedded waterstop model can be CB350×10-50.

[0059] For example, one end of the first waterstop 7 is buried in the interface end of the pipe trench 3, and the other end is buried in the building structure 1.

[0060] With the above settings, the first waterstop 7 can maintain the waterproof performance between the trench 3 and the building 1, and absorb the relative displacement between the trench 3 and the building 1.

[0061] The following example illustrates the specific dimensions of the connection structure between the building structure and the pipe trench:

[0062] like Figure 1 As shown, the cross-sectional dimensions of the pipe trench 3 are 4.0m × 4.0m, the wall thickness is 300mm, the length of the trench section is 24m, the first waterstop 7 is located at the center of the trench wall of the pipe trench 3, the embedded waterstop model is CB350×10-50, the diameter of the center hole of the embedded waterstop is 30mm, and the width of the expansion joint between the pipe trench 3 and the building structure 1 is 50mm.

[0063] The length of the support 2 extending out of the structure 1 can be set according to the length and burial depth of the trench 3 and working experience. Here, the length of the support 2 extending out of the structure 1 is set to 1000mm.

[0064] The cross-sectional dimensions of the retaining wall 5 can be set according to the length, burial depth and other data of the trench 3 and working experience. Here, the dimension of the retaining wall 5 extending out of the building 1 is set to 1000mm, and the width of the retaining wall 5 is set to 1000mm.

[0065] The inventor conducted actual tests, such as Figure 1As shown, after point A of the trench 3 settles, and the settlement amount h = 180 mm, the displacement of the bottom of the interface end of the trench 3 is approximately 0, and the displacement of the top of the interface end of the trench 3 is L1 = 30 mm. If the structure connecting the structure and the trench in this embodiment is not used, the deformation at the connection between the interface end of the trench 3 and the structure 1 should be 180 mm. Through the above comparison, it can be proved that the structure connecting the structure and the trench in this application can significantly reduce the settlement of the interface end of the trench 3, thereby reducing the deformation between the interface end of the trench 3 and the structure 1.

[0066] Example 2:

[0067] This utility model embodiment also provides a nuclear power plant building, which includes a building structure 1 and a pipe trench 3. The connection between the building structure 1 and the pipe trench 3 forms the building structure and pipe trench connection structure in embodiment 1.

[0068] In some examples, such as Figure 1 and Figure 2 As shown, when the trench 3 is formed by multiple segments, adjacent segments are connected by a second waterstop 6, which can also be a buried waterstop.

[0069] By implementing the above-mentioned measures, the settlement at the interface of the trench 3 can be reduced, thereby reducing the deformation between the interface of the building 1 and the trench 3 and improving the waterproof performance of the nuclear power plant building.

[0070] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
