Draining inspection shaft capable of controlling lifting, and manufacture method of draining inspection shaft

Abstract

The invention provides a draining inspection shaft capable of controlling lifting. The draining inspection shaft comprises a shaft and a lifting controlling base, wherein the lifting controlling base comprises an embedding part, a body part and a lifting control part,wherein the embedding part is embedded into the bottom of an internal chamber of the shaft; the body is positioned below the embedding part and is connected with the embedding part; the lifting control part extends outwards from the external wall of the body part; the top surface of the lifting control part is level to the bottom surface of the shaft; and a plurality of grouting holes are arranged on the wall of the shaft. The invention also provides a manufacture method of the draining inspection shaft capable of controlling lifting. According to the draining inspection shaft capable of controlling lifting and the manufacture method of the draining inspection shaft, the contact area between the lifting control base and the soil body is increased through the lifting control base, so that the bearing capacity of the draining inspection shaft is improved, and the lifting preventing effect is greatly improved; the grouting holes are preset on the wall of the shaft, which can be used for grouting the earth mass outside the shaft, and therefore, the strength of the earth mass can be effectively improved, and the tightness of the combination between the earth mass and the wall of the shaft can be effectively improved, and as a result, the effect of the draining inspection shaft on lifting preventing can be further improved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a settlement-controllable drainage inspection well and a manufacturing method thereof. Background technique [0002] At present, the drainage inspection wells under the urban roads are all made of red bricks or cast on site. After the road has been handed over for a period of time, thousands of drainage inspection wells on the road will sink, forming thousands of holes on the road. There are 1,230,000 drainage inspection wells in Wuhan alone, that is, more than 1 million pits; thereby producing the following problems: 1, forming uneven settlement of roads and drainage inspection wells, affecting the quality of roads and drainage inspection wells 2. Affect driving safety; 3. Great damage to vehicles and tires, high noise, high energy consumption, high cost, and not energy-saving and environmentally friendly; 4. Water leakage in drainage inspection wells and p...
