Artificially excavated riding well and construction method thereof

Abstract

The invention discloses an artificially excavated riding well. The artificially excavated riding well comprises a bricked protecting wall, a bricked well ring, a well lid and a reinforced concrete well ring, wherein graded broken stones are arranged at the bottom of the riding well, under a pipe and at the rear of the bricked protecting wall; a corrugated pipe is arranged in the graded broken stones; a reinforced concrete bottom plate is arranged on the graded broken stones; a certain number of PVC tubes are vertically arranged in the middle of the reinforced concrete well ring; and a pipe A and a pipe B are arranged on a side wall of the reinforced concrete well ring. The construction method comprises the following steps: (1) digging a hole artificially, and supporting by using a brick wall; (2) bricking to surround the well to the bottom of the well, laying a broken stone hardcore, burying a water channel tube, and placing a self-priming pump in the well for draining water; and (3) beginning to construct well bottom concrete cushion, and constructing the reinforced concrete bottom plate. The artificially excavated riding well has the advantages that the water percolating capacity of the structure is low, the water draining method is convenient and is good in water draining effect, the cost is low, particularly, water flowing out from the periphery of a dragging tube is guided out to guarantee that the bottom surface of concrete does not have accumulated water during pouring, and therefore, the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of inspection wells for sewage pipes and drainage pipes, in particular to a manually excavated riding well and a construction method thereof. Background technique [0002] When the sewage pipes and drainage pipes are designed as drag pipes, after the construction of the drag pipes is completed, a horse-riding well needs to be constructed. The depth between the top of the drag pipe and the top of the horse-riding well is generally more than 4m, and some are even more than 8m. There are three main construction schemes for riding a horse well. One is large-scale excavation construction. After all the soil in the construction area is dug out, the construction is carried out sequentially from bottom to top; the other is deep foundation pit support construction first, such as high-pressure jet jet piles, Then manual excavation, reverse construction; the other is manual excavation, while excavating and brick suppor...

Problems solved by technology

[0003] Option 1: The amount of excavation earthwork is large, and sometimes it is restricted by the terrain, so it cannot be excavated. When the groundwater level is high, the water seepage is relatively large, and the water seeping from the expansion hole of the drag pipe will flow deep into the well, causing the well to be damaged. The bottom is full of mud, which is not conducive to the construction of workers. It is necessary to set up sumps or wells for centralized drainage, which requires a large amount of work and high costs.

[0004] Option 2: The construction of deep foundation pit support requires temporary power consumption, the power load is large, the construction period is long, and the cost is high. There is still seepage at the reaming part of the drag pipe, which needs to be blocked or drained
