Abstract
Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of municipal drainage engineering, and particularly relates to a drainage engineering pipeline anti-floating construction structure. BACKGROUND
[0002] In the construction of municipal cross-road drainage pipelines, when the pipe covering depth does not meet the requirements, or when power and communication pipelines are constructed, it is often necessary to fully wrap the pipeline with concrete. The traditional cast-in-place concrete method is to install the pipeline after the formwork is set up and installed, and then pour the concrete. During the pouring process, if there is accumulated water in the trench due to rain, and the self-weight of the pipeline is less than the buoyancy, the pipeline will float and move, causing the pipeline interface to fall off, resulting in rework, increased construction cost and construction period.

[0011] Further, the tie steel bars are arranged along the longitudinal section, and the auxiliary steel bars are arranged along the longitudinal direction.
[0012] Further, the tie rope is an iron wire.
[0013] Further, the tie rope is arranged in an inverted U shape.
[0014] Further, the pipeline is arranged on the cushion layer.
[0015] Further, the pipe wrapping layer is a 360-degree full wrapping structure.
[0016] Advantages of the present application:
[0017] 1. The structure is reinforced by using steel scrap (manhole scrap, excess material), which does not increase additional cost during construction; the processing excess material can be fully utilized to meet the requirements of green construction, energy saving and emission reduction, and environmental protection.
[0018] 2. Improve construction efficiency, avoid rework, save cost, speed up construction progress, and realize effective utilization of resources and maximization of economic benefits.

[0025] Figure 2 is the side view of the structure of the present application.

[0027] The present application will be further described below in combination with specific embodiments and drawings.
[0028] Reference Figure 1 and Figure 2As shown, a drainage engineering pipeline anti-floating construction structure comprises a cushion layer 1, tie steel bars 2, auxiliary steel bars 3, tie ropes 4, a pipeline 5 and a pipeline wrapping layer 6.
[0029] The cushion layer 1 is the bottom part of the structure and is arranged above the soil layer to prevent the soil layer from eroding the upper structure and to form a construction base for the upper structure. The pipeline 5 is arranged on the cushion layer 1 and is wrapped by the pipeline wrapping layer 6 which is arranged above the cushion layer 1 to protect the pipeline 5. The pipeline wrapping layer 6 can partially wrap the pipeline 5 or completely wrap (full wrap) the pipeline 5.
[0030] The tie steel bars 2 are arranged on the two sides of the cushion layer 1 and are used as two anchor points. The tie ropes 4 are connected between the two tie steel bars 2 and are arranged around the pipeline 5 to pull the pipeline 5 to overcome the upward floating force of the pipeline 5 and prevent the pipeline 5 from moving upward.
[0031] The application combines the characteristics of pipeline cushion layer construction and pipeline wrapping concrete pouring construction. During the pipeline cushion layer construction, the tie steel bars are fixed on the two sides of the pipeline by using steel waste. After the pipeline is installed, the pipeline is pulled to the cushion layer by the tie ropes to form a tensile and compressive complex of the pipeline wrapping concrete, the pipeline and the cushion layer concrete. The tie steel bars are gripped by the concrete cushion layer, and the self-weight pressure of the pipeline wrapping concrete and the cushion layer concrete acts on the pipeline to prevent the pipeline from floating due to the concrete pouring process or water accumulation in the trench.
[0032] The cushion layer 1 is a C20 concrete structure, and the thickness of the concrete cushion layer is 80-120mm or the wall thickness of the pipeline during the municipal engineering construction process. The tie steel bars 2 are pre-embedded structures and are arranged in the cushion layer 1 during the pouring of the cushion layer 1 and are partially exposed.
[0033] The auxiliary steel bars 3 are arranged in the cushion layer 1 and are crosswise and fixedly connected to the tie steel bars 2. Several auxiliary steel bars 3 can be arranged on each tie steel bar 2 and are bound to the tie steel bars 2 by iron wires or are directly welded to the tie steel bars 2 to form a cross structure to improve the anchoring strength of the tie steel bars 2.
[0034] When the pipeline has a relatively light self-weight or is fully wrapped by 360-degree concrete, the pipeline receives a relatively large upward floating force. When the gripping force of the tie steel bars and the cushion layer concrete is insufficient to offset the upward floating force of the pipeline, the auxiliary steel bars are added for reinforcement. Similarly, the spacing of the tie steel bars can be adjusted to change the anti-floating tension received by the tie steel bars, and the length and spacing of the auxiliary steel bars can be adjusted to adjust the tension.
[0035] The tie steel bars 2 and the auxiliary steel bars 3 are made of the processing waste and excess material of the common inspection well, and the specifications are Φ12 mm or Φ14 mm. The tie steel bars 2 are preferably arranged along the longitudinal section, and the auxiliary steel bars 3 are preferably arranged along the longitudinal direction. Similarly, the tie steel bars 2 and the auxiliary steel bars 3 can also be arranged along other directions, and the crossing of the two steel bars is preferably maintained.
[0036] The tie steel bars 2 are L-shaped structures, the horizontal sections of the tie steel bars 2 are located in the cushion layer 1, and the vertical sections of the tie steel bars 2 extend out of the cushion layer 1. The extending parts (vertical sections) of the tie steel bars 2 are provided with tie bends 201, the tie bends 201 are connected with the tie ropes 4, and the connection of the tie ropes 4 on the tie steel bars 2 is facilitated.
[0037] The tie ropes 4 are No. 8 or No. 10 iron wires, and can also be other ropes. The tie ropes 4 are arranged in an inverted U shape, and are directly buckled on the pipelines 5 to realize the limiting of the pipelines 5. Similarly, the tie ropes 4 can also be wound on the pipelines 5 in other ways, as long as the pipelines 5 can be pulled.
[0038] The pipelines 5 are arranged on the cushion layer 1, and the tie ropes 4 can be directly pulled tight during operation, which facilitates the tie operation. After being pulled tight, the pipelines 5 are supported by the cushion layer 1, and the pipelines 5 are also facilitated to be arranged and fixed.
[0039] The pipe wrapping layer 6 is a C30 concrete structure, and the pipe wrapping layer 6 is preferably a 360-degree full wrapping structure. Similarly, the pipe wrapping layer 6 can also be in the form of local wrapping.
[0040] The foregoing basic examples and each further selected example of the present application can be freely combined to form a plurality of embodiments, which are all the embodiments that can be used and claimed by the present application. In the present application scheme, each selected example can be arbitrarily combined with any basic example and selected example.
[0041] The above only describes the preferred embodiments of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
