Description

Technical Field

[0001] This utility model relates to the field of municipal construction, and in particular to a soil improvement and reinforcement structure for municipal pipeline networks. Background Technology

[0002] Municipal pipeline networks are an important component of urban infrastructure, encompassing various types of pipes and facilities, and designed to provide essential public services to urban residents and businesses. Currently, the laying of municipal pipeline networks requires first excavating a foundation pit, then laying the pipelines, and finally backfilling the foundation pit.

[0003] However, in the traditional laying process, due to the relatively loose underground soil and the long construction time of municipal pipelines, the stress environment around the municipal pipelines changes due to the influence of hydrology, geology and load, which can easily cause problems such as pipeline deformation, damage and leakage, and needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a soil improvement and reinforcement structure for municipal pipeline networks, which has the effect of ensuring the stability of underground soil structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a soil improvement and reinforcement structure for municipal pipeline networks, comprising:

[0006] Municipal road surfaces, with foundation pits to accommodate municipal pipelines;

[0007] Cast-in-place piles are vertically and evenly installed on the bottom wall of the foundation pit;

[0008] A pad is horizontally placed on the cast-in-place pile;

[0009] Fasteners are provided on the two outermost piles and are used to connect the pads.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the fastener includes a pre-embedded bolt and a nut, the pre-embedded bolt is vertically disposed at the upper end of the cast-in-place pile, the two sides of the pad are provided with mounting holes for the pre-embedded bolt to pass through, and the nut is threadedly connected to the upper end of the bolt and presses the pad.

[0011] In a preferred embodiment, the present invention can be further configured such that: the two sides of the pad are bent upward and provided with baffles.

[0012] In a preferred embodiment, the present invention can be further configured such that: one end of the pad is provided with a locking block, and the other end is provided with a slot for the locking block to be inserted.

[0013] In a preferred embodiment, the present invention can be further configured such that: a rubber plate is vertically disposed on the upper end surface of the pad, and an arc-shaped groove is disposed on the upper end surface of the rubber plate.

[0014] In a preferred embodiment, the present invention can be further configured such that the inner sides of the pad and the baffle are provided with mounting grooves for embedding the rubber plate.

[0015] In a preferred embodiment, the present invention can be further configured such that: both ends of the rubber plate are provided with locking blocks, and the inner wall of the stop bar is provided with locking grooves for the locking blocks to be embedded.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. By arranging cast-in-place piles in the foundation pit, the soil location for laying municipal pipelines is reinforced, allowing cement grout to penetrate into the soil, improving the structural strength and stability of the soil, and using pads to support the municipal pipelines in order to resist geological factors and prevent damage to the municipal pipelines.

[0018] 2. By installing rubber sheets to support municipal pipelines, the shock absorption capacity of municipal pipelines is increased, the impact on the ground soil is reduced, and the structural strength and stability of the soil are ensured. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, a soil improvement and reinforcement structure for municipal pipelines includes a municipal road surface 1, cast-in-place piles 2, a base plate 3, and fasteners 4.

[0024] like Figure 2 As shown, the municipal road surface 1 has a foundation pit 11 to accommodate municipal pipelines. The cast-in-place piles 2 are vertically and evenly arranged on the bottom wall of the foundation pit 11. The pad 3 is horizontally arranged on the cast-in-place piles 2. The fasteners 4 are arranged on the cast-in-place piles 2 on both sides and are used to connect the pad 3.

[0025] like Figure 2 As shown, the fastener 4 includes a pre-embedded bolt 41 and a nut 42. The pre-embedded bolt 41 is vertically set at the upper end of the cast-in-place pile 2. The two sides of the pad 3 are provided with mounting holes 43 for the pre-embedded bolt 41 to pass through. The nut 42 is threaded to the upper end of the bolt and presses the pad 3.

[0026] Therefore, by arranging cast-in-place piles 2 in the foundation pit 11, the soil location for laying municipal pipelines is reinforced, allowing cement grout to penetrate into the soil, improving the structural strength and stability of the soil, and in conjunction with the pad plate 3, the municipal pipelines are supported to resist geological factors and avoid damage to the municipal pipelines.

[0027] like Figure 2 As shown, the pad 3 has upward-bent baffles 5 on both sides to limit the lateral movement of municipal pipelines and ensure the stability of the pipelines during installation. One end of the pad 3 is provided with a locking block 31, and the other end is provided with a slot 32 for the locking block 31 to be inserted, so as to achieve a stable connection between adjacent pads 3 and increase the stability between the pads 3.

[0028] like Figure 2 As shown, a rubber plate 6 is vertically installed on the upper surface of the pad 3. The upper surface of the rubber plate 6 is provided with an arc-shaped groove 61 to support the municipal pipeline, increase the shock absorption capacity of the municipal pipeline, reduce the impact on the ground soil, and ensure the structural strength and stability of the soil.

[0029] like Figure 2 As shown, the inner sides of the pad 3 and the baffle 5 are provided with mounting grooves 7 for the rubber plate 6 to be embedded, which increases the stability of the rubber plate 6 and prevents the rubber plate 6 from moving. Both ends of the rubber plate 6 are provided with locking blocks 62, and the inner wall of the baffle 5 is provided with locking grooves 63 for the locking blocks 62 to be embedded, in order to increase the stability of the rubber plate 6 and prevent the rubber plate 6 from slipping.
