According to the situation of customers ordering pe drainage inspection chamber in the past, some customers want to know more about the construction knowledge of pe drainage inspection chamber. Our factory has professional technicians who have a better understanding of municipal construction and other aspects. Here I will introduce to you the impact of inspection well diseases on road smoothness and its countermeasures. Customers in need can refer to it by themselves.

Analysis of Causes of Inspection Well Diseases

Influence of material properties and material strength

There is considerable variation in the stiffness and strength of the various materials within and around the manhole. Road base materials (fly ash or cement-stabilized soil), inspection chamber prefabricated cover, asphalt pavement, and inspection well cast iron cover are made of different materials, and their strength, elastic modulus, thermal expansion coefficient, and elastic-plastic deformation under external force are all different.  Inspection wells generally belong to masonry structures with an elastic modulus of 1200MPa. Inspection well covers are generally cast iron materials with an elastic modulus of 2.1×105MPa, while the elastic modulus of general filled soil roadbeds is only 30.80MPa when the compaction degree reaches 95%. ; The difference in material makes the temperature coefficient of the inspection well and the surrounding roadbed different, and the deformation under the external load is also different. Due to the need for elevation adjustment, pea-rock concrete cushions (or leveling layers) are generally provided between the inspection well circle and the well body. The most common occurrence is that the strength of the pea stone concrete leveling layer at the lower part of the cast iron well circle is low, and it is broken under a large load, causing the well circle and the well cover to sink as a whole. The traditional concept holds that the load on this floor is not large, and the design strength level often does not exceed C15, but the fact is just the opposite. Calculation shows that when heavy road rollers or heavy overloaded vehicles run over the well circle, especially in the case of one-sided force on the well circle, the stress on the bean stone concrete cushion under the well circle is very uneven, and the local stress is concentrated. There will be a dangerous phenomenon that the instantaneous stress exceeds the standard strength of low-grade concrete.

Check the impact of well circle structure size

The current standard inspection well ring height is 12cm, and the actual thickness of the asphalt surface layer on the pavement is about 10-12cm. During the construction, the asphalt layer is generally paved in two times, and the well ring is generally installed before the first layer is paved. The thickness of the first layer of paving is about 5 mm, which is not enough to stabilize the well ring. Rollers are often found during construction. Afterwards, the well ring becomes loose. Municipal maintenance experts believe that the more reasonable height of the inspection well circle is about 18cm. In this way, when the first layer of asphalt is paved, two-thirds of the height can be guaranteed to be buried under the first-laid asphalt layer, which can better stabilize the well circle and prevent the well circle from being displaced or loosened by the road roller.

The influence of various factors in the construction stage

The excavation size of the inspection well foundation pit is too small, and the backfill quality is affected. According to the construction regulations, the compaction degree of the backfill soil around the inspection well under the urban road should be the same as that of the road base layer, that is, heavy-duty

More than 95% of the compaction standard. During backfilling of urban road construction, surface muck should be completely removed and replaced with well-graded soil. However, since the amount of backfill soil around the inspection well is not very large, the quality control is not paid attention to in many construction sites, and the surface muck, broken bricks and other humus-containing soils are often backfilled in the inspection well. Around the well, these miscellaneous fills are difficult to be compacted during construction, and obvious settlement will occur later, causing ground subsidence. The ground radar scanning picture also shows that there is indeed a ring-shaped loose area around the inspection well with poor construction quality. Insufficient strength of mortar joints in masonry pe drainage inspection chambers. The mortar quality of pe drainage inspection chamber constructed by masonry method is poor, the mortar joints are not full, or the mortar is eager to backfill before the mortar reaches its strength due to rush work. Blocks must be displaced, so that the pre-compacted backfill around the well enters new gaps, causing the well body to sink, the well circle to shift, and the backfill around the well to subside.

The influence of driving action

The road surface mainly bears the pressure, shear force and impact force of the live load of the vehicle. When the vehicle passes the pe drainage inspection chamber, in addition to the gravity of the vehicle itself, due to the difference in physical properties between the inspection well cover seat and the asphalt pavement material and the inspection well cover and the road surface. When driving, it will generate impact load on the pe drainage inspection chamber and generate large shear stress on the surrounding road surface. The impact force of the vehicle load will aggravate the sinking of the pe drainage inspection chamber, the increase of shear force intensifies the formation of cracks in the surrounding pavement.

The above diseases of pe drainage inspection chambers are mainly based on the analysis of domestic use and construction conditions. Customers can make selective reference according to their own regions when making reference. Customers who need relevant knowledge points and prices of inspection wells, please leave us a message.

Measures and Countermeasures

Based on the above analysis, the following measures and countermeasures are put forward in order to reduce or even eliminate pe drainage inspection chamber diseases.

1. Improve the design strength of the pea-stone concrete cushion under the cast iron well ring, pay attention to the maintenance of the cushion during the construction stage, and the road surface rolling construction can only be carried out when the cushion strength is close to the design value, so as to avoid the pea-stone concrete cushion under heavy load broken.

2. It is recommended to use the prefabricated concrete straight neck well circle connected with the cast iron well circle, and move the bean stone concrete cushion to the lower part of the prefabricated concrete straight neck well circle to avoid crushing or extrusion of the bean stone concrete cushion.

3. It is recommended to use concrete inspection wells or prefabricated concrete inspection wells to ensure the structural safety of the well body and wellbore under the action of vibratory rollers; strictly control the quality of inspection well masonry, and do not use heavy equipment to backfill the mortar joints before reaching the design strength .

4. Strictly control the quality and compaction of the backfill soil around the well and between the subgrade; it should meet the requirements of the construction specification; Body leakage causes frost heave.

5. It is advocated to cover the inspection well first, and after the paving of the road asphalt surface is completed, cut the surface to install the well circle and the well cover.

6. Add fiberglass grids to the mixture in the asphalt pavement paved around the inspection well to delay the appearance of cracks in the pavement pavement.

7. Management should be strengthened and overloaded trucks should be avoided to inspect well rings and well covers as much as possible during use.

The above solutions are suggestions based on the above analysis, and customers in need can refer to local professional construction personnel. PE drainage inspection chamber with different parameters can be applied in different places, please refer to the table in this article for detailed parameters.
