Detailed Description

For a better understanding of the technical content of the present utility model, specific examples are set forth below, along with the accompanying drawings.

Referring to fig. 1, the present utility model provides an anti-floating device for an underground pipeline, which comprises a pipe trench 100 and a supporting seat 10, wherein the pipe trench 100 and the supporting seat 10 are formed by a concrete structure, concrete is filled in the excavated trench, the sectional shape is as shown in the figure, after the construction of the pipe trench 100 is completed, the supporting seat 10 is constructed, and the supporting seat 10 is arranged at the bottom of the pipe trench 100.

In a specific embodiment, the support base 10 comprises a base portion 11 at the bottom and an extension portion 12 at the top, the base portion 11 being configured as a frustum and the extension portion 12 being configured as a U. The interior of the base portion 11 is embedded with reinforcing bars 14, the reinforcing bars 14 extending into the trench 100.

In this way, the support bracket 10 and the pipe trench 100 can be ensured to have good combination capability, and the space in the pipe trench 100 is divided into a support groove 102 positioned at the middle part for supporting the pipeline 200 and a sewage disposal groove 101 formed between the support bracket 10 and the inner wall of the pipe trench 100 by the separation function of the support bracket 10.

The supporting groove 102 is used for supporting the bottom surface and part of the side surface of the pipeline 200, so that the sludge is prevented from being filled into the lower part of the pipeline 200 and floating upwards. Preferably, the depth of the holding tank 102 is greater than one-half the diameter of the pipe 200.

Further, along the length direction of the support base 10, a plurality of drainage grooves connecting the support groove 102 and the drainage groove 101 are arranged on the support base 10.

It will be appreciated that the lower the mobility of the sludge is, the better the mobility of the sludge is, the higher the mobility is, and as shown in fig. 2, the larger the specific gravity of the sludge is in the bottom of the sewage tank 101, the higher the mobility is in the upper part of the sewage tank 101, and when the sludge in the sewage tank 101 flows outside the support base 10, the space at the other end of the drainage tank is attracted, i.e. the sludge or fluid in the bottom of the support tank 102 can be pumped into the sewage tank 101, so as to avoid the accumulation of more sludge in the support tank 102.

Further, the inner wall of the holding tank 102 is provided with a concave-convex structure along the length direction of the holding tank 102 to prevent the fluid from flowing in the holding tank 102 along the length direction. In this way, the sludge or mixed fluid in the holding tank 102 is prevented from flowing along the length direction of the holding tank 102, so that the medium flowing in the sewage tank 101 is ensured to have an attractive effect on the medium in the holding tank 102.

It will be appreciated that typically underground pipes are corrugated or smooth surfaced steel pipes and that in alternative embodiments, the sink 121 has a support plate 13 disposed therein, the support plate 13 extending upwardly and above the support trough 102, the support plate 13 having a curved surface conforming to the outer wall of the pipe 200.

When the supporting plate 13 supports the steel pipe, the fluid can be effectively prevented from sliding in the bearing groove 102 along the length direction of the steel pipe, and when the supporting plate 13 supports the corrugated pipe, the fluid can be prevented from sliding and simultaneously can be embedded into the gap of the corrugated pipe, so that the floating of the corrugated pipe is prevented.

In an alternative embodiment, as shown in connection with fig. 3-4, the drainage channel comprises a sink channel 121 and a guide channel 122, the sink channel 121 being located at the surface of the holding tank 102 and extending towards the outer wall of the holding seat 10, the guide channel 122 having a first end connected to the sink channel 121 and a second end communicating with the drain channel 101.

As shown in connection with fig. 4, the fluid flow rate in the sump 101 is greater than the fluid flow rate in the holding tank 102, so that the fluid medium in the guide groove 122 is sucked outwardly into the sump 101 to avoid accumulation of the fluid medium in the holding tank 102, and thus the pipe 200 floats.

In combination with the embodiment, the supporting seat is arranged in the pipe ditch, the supporting seat divides the space in the pipe ditch into the part for supporting the pipeline and the part for flowing the silt medium, and the supporting seat is provided with the groove for connecting the two parts, so that when the silt flowing part outside the supporting seat flows, attractive force can be generated for supporting the pipeline part, accumulation of the silt medium in the supporting seat is avoided, and the pipeline is prevented from floating up until the pipeline structure is damaged.

While the utility model has been described with reference to preferred embodiments, it is not intended to be limiting. Those skilled in the art will appreciate that various modifications and adaptations can be made without departing from the spirit and scope of the present utility model. Accordingly, the scope of the utility model is defined by the appended claims.
