Background technique

In municipal planning and construction, the construction of sewage pipes is one of the main projects of municipal construction, and it is a very important component, which will affect the quality of life of urban residents and also affect the development of the city. With the expansion of city scale and the increase of urban population, the discharge and treatment of sewage is an important part of the current municipal construction. Sewage pipes are an important part of the urban drainage system, which greatly affects the effect of urban construction, especially the speed of modern city development is accelerating, and the economy is rapidly improving. At the same time, the amount of sewage generated by production and life is also increasing. If the sewage is not properly discharged It is easy to have a bad influence on the construction effect of the city.

In the existing sewage pipeline construction, HDPE plastic-steel winding pipes are used for sewage pipeline construction. For the landfill soil above the sewage pipeline, the land above the sewage pipeline is mostly compacted by manual compaction.

Utility model content

The purpose of this utility model is to solve the problem that the backfill compactness is weak during the traditional sewage pipeline backfill construction process. In order to ensure that the pipeline backfill can be constructed normally and safely, the utility model first adopts an excavator flat compacting device, which is used in the sewage pipeline backfill construction. This technique has become a widely used form of building construction. Using the free fall of the plate tamping device to tamp the foundation and filling soil and rocks to improve their compactness can greatly save the construction period, reduce economic losses, and improve construction efficiency.

In order to achieve the above purpose, the technical solution adopted by the utility model is a flat compacting device for urban sewage pipelines. ; Between the sliding sleeve 2 and the vertical guide rod 1 is a sliding fit, the sliding sleeve 2 is welded in the middle of the plate ram head 3, the bottom of the hydraulic telescopic arm 4 can be flexibly connected with the upper part of the plate ram head 3; the hydraulic telescopic arm 4 The top of the top is connected with the hydraulic arm of the excavator; the plate ram head 3 and the circumferential direction of the sliding sleeve 2 are welded with stiffening plates 5 evenly and equidistantly.

Flat rammer head 3 is a rectangular steel plate.

The flat plate compacting device of the utility model can improve the construction of sewage pipelines, has less one-time investment, saves costs, has good applicability, and is safe and reliable in the compaction process. Compared with ordinary manual compaction, the compaction quality of earthwork construction is significantly higher Due to the quality of manual compaction, the compaction strength that is difficult to achieve by manual compaction is achieved, the construction period is shortened, and the construction cost is saved.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawings and embodiments.

As shown in Figure 1-3, a flat compacting device for urban sewage pipelines, the flat compacting device includes a vertical guide rod 1, a sliding sleeve 2, a flat tamper head 3, a hydraulic telescopic arm 4 and a stiffening plate 5; the sliding sleeve 2 It is a sliding fit with the vertical guide rod 1, the sliding sleeve 2 is welded in the middle of the plate ram 3, the bottom of the hydraulic telescopic arm 4 can be flexibly connected with the upper part of the plate ram 3; the top of the hydraulic telescopic arm 4 is connected to the excavator The hydraulic arm is connected; the plate rammer head 3 and the sliding sleeve 2 are welded with stiffening plates 5 evenly and equidistantly in the circumferential direction.

Flat rammer head 3 is a rectangular steel plate.

The flat plate compacting device of the utility model can improve the construction of sewage pipelines, has less one-time investment, saves costs, has good applicability, and is safe and reliable in the compaction process. Compared with ordinary manual compaction, the compaction quality of earthwork construction is significantly higher Due to the quality of manual compaction, the compaction strength that is difficult to achieve by manual compaction is achieved, the construction period is shortened, and the construction cost is saved.

According to the construction requirements of the project, in order to improve the efficiency of the sewage pipeline in the pipeline construction and ensure the construction quality, the sewage pipeline construction equipment is improved and perfected. The project added a set of plate compaction devices to the sewage pipeline equipment to ensure strong compaction during the construction process of sewage pipeline backfill, and at the same time ensure strong impact compaction effect and large fill thickness of sewage pipeline backfill. After improvement, the construction quality of the sewage pipeline has been improved, and the construction efficiency has been improved at the same time.

The plate compacting device includes a plate compacting head, the plate compacting head consists of a compacting plate, a stiffening plate and a connecting rod, the compacting plate is a rectangular steel plate, the bottom of the compacting plate is flat, and there is a cylindrical sliding sleeve in the middle The outer wall of the sliding sleeve is radially connected with stiffening plates, the connecting seat is connected with one end of the hydraulic telescopic arm, the other end of the hydraulic telescopic arm is connected with the hydraulic arm of the excavator, and the hydraulic arm of the excavator is hinged with the power arm of the excavator.

The stiffening plate is a right-angled triangle, distributed evenly and equidistantly around the connecting seat, one right-angled side is welded to the connecting seat, and the other right-angled side is welded to the tamping plate. The reciprocating motion of the hydraulic cylinder of the excavator drives the alternate tamping of the tamping plate to tamp the earth and stone. During the tamping process, vibration and tamping are carried out from top to bottom. The two adjacent tamping surfaces overlap each other, thus ensuring the slope surface of the lake bank. Construction quality of earthwork compaction.

Initially, the plate ram head 3 is on the ground, and the hydraulic telescopic arm 4 stretches to pull the plate ram head 3; the hydraulic telescopic arm 4 retracts to pull up the plate ram head 3, and the hydraulic telescopic arm 4 and the plate ram head 3 are released. Plate tamp head 3 freely falls to exert pressure on the ground. The tamping process is safe and reliable. Compared with ordinary manual tamping, the tamping quality of earthwork construction is significantly higher than that of manual tamping, reaching a tamping strength that is difficult to achieve by manual tamping, ensuring the construction quality of pipeline backfill and providing a good foundation for follow-up work , saving the construction period.
