Description

Technical Field

[0001] This application belongs to the field of pipe sleeper technology, specifically relating to a concrete pipe sleeper for water supply and drainage pipelines. Background Technology

[0002] In the construction of water supply and drainage pipelines in municipal engineering, concrete pipe sleepers are key components for pipeline positioning and load transfer, and their performance directly affects the stability of the pipeline system.

[0003] Currently, the commonly used cast-in-place concrete pipe supports have the following drawbacks: poor structural adaptability; traditional pipe supports use an integral semi-circular groove structure, whose radius of curvature is strictly matched with the outer diameter of the pipe, resulting in the need to remake a special mold for each pipe diameter change, significantly increasing material inventory costs and construction preparation time; insufficient limiting function; pipe installation relies solely on gravity and passive constraint of the groove, without an active locking mechanism, making it prone to lateral axial movement under external disturbances; and lack of adjustment mechanism; existing pipe supports are installed in fixed pre-embedded positions, lacking the ability for on-site fine-tuning. When encountering complex geological conditions (such as uneven settlement of soft soil foundations), it is impossible to achieve pipe axis correction through local position compensation adjustment. Utility Model Content

[0004] The purpose of this application is to provide a concrete pipe sleeper for water supply and drainage pipelines, which is a concrete pipe sleeper structure that combines adjustability, seismic resistance and high stability. Through modular structural design, it realizes multi-dimensional displacement constraint and rapid adaptation installation of pipelines, and solves the problems of poor adaptability and lack of adjustment mechanism of existing pipe sleepers.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A concrete pipe sleeper for water supply and drainage pipelines includes a base and at least two sets of limiting blocks and limiting rod assemblies. The base includes a flat support plate with several first limiting grooves in the longitudinal direction arranged in the transverse direction. The limiting blocks include vertical blocks with sliding cantilever arms at the lower part of the vertical blocks. The sliding cantilever arms are slidably fitted with the flat support plate in the transverse direction. The vertical blocks are provided with second limiting grooves in the longitudinal direction. The first limiting grooves and the second limiting grooves are opposite to each other and form limiting slot holes. The limiting rod assemblies are engaged in the limiting slot holes.

[0007] Furthermore, both the base and the limiting block are integral concrete structures.

[0008] Furthermore, at least two vertical support plates are arranged horizontally at the lower part of the flat support plate.

[0009] Furthermore, the flat support plate includes a grooved section and a smooth section, with the smooth section located between the two grooved sections.

[0010] Furthermore, the sliding cantilever includes L-shaped cantilever arranged at both ends of the vertical stop block, and the L-shaped cantilever at both ends of the vertical stop block is slidably fitted with the flat support plate.

[0011] Furthermore, the sliding cantilever has through holes for rod groups, and the limiting rod group is fixed on the base. The limiting rod group passes through the through holes and is locked in the limiting slot.

[0012] Furthermore, the first limiting groove is located on the upper surface of the flat support plate, and the second limiting groove is located on the lower surface of the vertical stop block.

[0013] Furthermore, both the first limiting groove and the second limiting groove are semi-circular annular grooves.

[0014] Furthermore, the spacing between the first limiting grooves is 50-100mm.

[0015] Furthermore, the limiting rod assembly includes a double-ended screw, with nuts at both ends of the double-ended screw.

[0016] The beneficial effects of this application are:

[0017] 1. By combining modular base with adjustable limit blocks, a single pipe support can be adapted to multiple pipe specifications, reducing construction costs.

[0018] 2. The double-T-shaped base structure has higher bending stiffness than the traditional rectangular section, effectively preventing pipe sleeper breakage caused by foundation settlement.

[0019] 3. On-site installation only requires adjusting the positioning of the double-ended screw and then tightening the nut, resulting in high installation efficiency.

[0020] 4. It can achieve multi-dimensional displacement constraints, and is suitable for complex working conditions such as soft foundations and high seismic zones, significantly improving the safety and construction efficiency of pipeline projects.

[0021] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding this solution, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

Detailed Implementation

[0026] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0027] Example

[0028] refer to Figs. 1-3 As shown, a concrete pipe sleeper for water supply and drainage pipelines includes a base 1, a limiting block 2, and a limiting rod assembly 3.

[0029] The base 1 is used for bottom support and provides a foundation for the placement of the limiting block 2. The base 1 includes a flat support plate 101, a vertical support plate 102, a first limiting groove 103, a groove section 104, and a smooth section 105. The base 1 is an integral concrete structure, that is, the flat support plate 101 and the vertical support plate 102 are integral concrete structures.

[0030] At least two sets of limiting blocks 2 are arranged to limit the lateral and left-right movement of the pipeline, ensuring the stability of the pipeline installation. The limiting blocks 2 include a vertical block 201, a sliding cantilever 202, a second limiting groove 203, and a rod assembly through hole 204. The limiting blocks 2 are all integral concrete structures, that is, the vertical block 201 and the sliding cantilever 202 are integral concrete structures.

[0031] The lower part of the vertical stop block 201 is provided with a sliding cantilever 202. The sliding cantilever 202 is slidably fitted with the flat support plate 101 in the horizontal direction. Thus, the vertical stop block 201 can slide and adjust left and right relative to the flat support plate 101. Due to the fitted relationship, the vertical stop block 201 cannot rotate relative to the flat support plate 101 along the horizontal axis, forming a locking to ensure the vertical blocking state of the vertical stop block 201.

[0032] The flat support plate 101 has several first limiting grooves 103 arranged in the longitudinal direction along its transverse direction, and the vertical stop block 201 has second limiting grooves 203 arranged in the longitudinal direction. The first limiting grooves 103 and the second limiting grooves 203 are opposite to each other and form a limiting slot hole. The limiting rod assembly 3 is locked in the limiting slot hole, that is, the limiting rod assembly 3 is simultaneously locked between the flat support plate 101 and the vertical stop block 201, realizing the locking of the transverse position of the vertical stop block 201 and meeting the requirement of fixing the vertical stop block 201. When the limiting rod assembly 3 is removed from the limiting slot hole, the position of the vertical stop block 201 can be adjusted.

[0033] At least two vertical support plates 102 are arranged in the lower part of the flat support plate 101 in the transverse direction. Preferably, two vertical support plates 102 are arranged to form a double T-shaped structure. This structure has improved bending stiffness compared with the traditional rectangular section and effectively prevents pipe sleeper breakage caused by foundation settlement.

[0034] The flat support plate 101 includes grooved sections 104 and smooth sections 105, which are arranged alternately. The smooth sections 105 are located between two grooved sections 104. The grooved sections 104 are plate sections with several first limiting grooves 103, while the smooth sections 105 are plate sections without first limiting grooves 103, providing a smooth surface for support and facilitating the placement of pipelines on the flat support plate 101. Similarly, if the smooth sections 105 are not present, pipelines can be directly placed on the limiting grooves.

[0035] The sliding cantilever 202 includes L-shaped cantilever arms arranged at both ends of the vertical stop block 201. The L-shaped cantilever arms at both ends of the vertical length are opposite to each other, and the L-shaped cantilever arms at both ends of the vertical length are fitted with the flat support plate 101 in a sliding fit. That is, a T-shaped groove is formed between the L-shaped cantilever arms at both ends of the vertical length, and the flat support plate 101 is slidably placed in the T-shaped groove, which has the effect of lateral sliding and also has the effect of fitting and limiting.

[0036] The limiting rod assembly 3 is fixed on the base 1 to ensure its own fixed position. The sliding cantilever 202 is provided with rod assembly through holes 204. Preferably, the rod assembly through holes 204 are arranged at both ends of the longitudinal direction of the sliding cantilever 202. The limiting rod assembly 3 passes through the rod assembly through holes 204 and is locked in the limiting slot, so that the limiting rod assembly 3 enters the limiting slot.

[0037] The first limiting groove 103 is located on the upper surface of the flat support plate 101. Specifically, the first limiting groove 103 extends through the longitudinal direction of the upper surface of the flat support plate 101. The first limiting grooves 103 are arranged at equal intervals, with a spacing of 50-100mm, forming a standardized positioning reference. The second limiting groove 203 is located on the lower surface of the vertical stop block 201. The second limiting groove 203 and the rod assembly through hole 204 together extend through the longitudinal direction of the vertical stop block 201, realizing the relative vertical arrangement of the first limiting groove 103 and the second limiting groove 203.

[0038] The first limiting groove 103 and the second limiting groove 203 are both semi-circular annular grooves, so the corresponding limiting rod group 3 is also a cylindrical structure to achieve matching with the formed cylindrical limiting groove hole.

[0039] The limiting rod assembly 3 is made of metal and at least two sets are required, corresponding to the number of limiting blocks 2. The limiting rod assembly 3 includes a double-ended screw 301 and nuts 302, with nuts 302 at both ends of the double-ended screw 301. After the limiting block 2 is in place, the double-ended screw is inserted into the hollow round hole and the anti-loosening bolt is tightened to fix the position of the block. The limiting blocks can be adjusted to the corresponding positions according to different pipe diameters.

[0040] Usage Procedure: Install base 1 on a compacted foundation according to the designed spacing. Several base 1 units are arranged longitudinally to ensure stable support for the pipeline. Select a positioning point for the semi-circular groove of the base that matches the pipe diameter. Move the limiting block 2 to the corresponding position and place the cantilever leg of the limiting block 2 across the top surface of the base, aligning the two semi-circular grooves. Insert the double-ended threaded rod and symmetrically tighten the anti-loosening nuts, applying a torque of 30-50 N·m to securely lock the limiting block 2. Place the pipeline between base 1 and the limiting blocks 2 on both sides. After positioning, check the uniformity of contact between the rubber buffer layer and the pipe wall.

[0041] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
