Abstract
The utility model relates to manhole field, particularly relates to a kind of manhole well seat.Well seat comprises base and the seat body for being connected with pit shaft, and be connected bottom the seat body that base top adduction and internal diameter are less than base, described base is sphere, and chassis interior forms mud sinking chamber; Described base outer wall is provided with some main muscle of warp-wise being extended to base top by base bottom center, and base outer wall is provided with the auxiliary muscle of broadwise arranged in parallel perpendicular to the main muscle of warp-wise, and described base is provided with the arm of draining.The intensity of base increases, and stock utilization is high.
Description
Technical field
The utility model relates to manhole field, particularly relates to a kind of manhole well seat.
Background technology
Manhole is the maintenance such as power supply, feedwater, draining, communication, cable television, gas pipe, public lighting circuit for Urban Underground infrastructure, easy for installation and arrange.Generally be located on pipeline intersection, turning, caliber or gradient change place and straight line pipeline section and locate at a certain distance so that make regular check on, the well shape structure of clean and dredging or down-hole operation inspection.
Traditional manhole mainly adopts brick concrete to be prepared from, and is by concrete, the materials such as mortar, brick, rubble, produces according to respective specified manufacture.Existing manhole mostly is brick concrete inspection well, mainly there is following shortcoming in it: first intensity is low, quality stability is poor, and the support strength of brickwork construction is low, and the brickwork construction reducing reducing part especially near road surface is easily subsided because the horizontal active force of imbalance impacts; Secondly, speed of application is slow, the well body construction cycle is long, construction is complicated, owing to piling up at manual scene, requires high to civil engineering, standardization, generalization, seriation degree are poor, manual and materials number be the key factor affecting quality, on the impact of environment and urban traffic greatly, do not meet the requirement of civilized construction, rapid construction; Exist in addition and can not change, easily break and seepage and the defect such as to pollute, need frequently keep in repair.
Plastic inspection well refers to that the main well seat part forming manhole adopts once injection moulding, and pit shaft socket adopts 360 degree of ring-like carrying platforms, and adopt netted reinforcing rib bottom well bore and well seat, each bell and spigot adopts ring-like reinforcing rib design.Initial well seat, straight-through well seat, one eighth bend well seat, three drifting seats, four drifting seats etc. are had according to adapter number is different with angle.In order to adapt to various drainage condition, the plastics integrated injection molding accessory that plastic inspection well is simultaneously supporting reducer union, the joint that confluxes, pit shaft polylinker etc. are supporting with it.To ensure smoothness and the sealing of whole drainage system.
Plastic inspection well simple installation, lightweight, be convenient to transport and install, dependable performance, bearing capacity are strong, good impact resistance, and corrosion-resistant, ageing-resistant, easy to connect with plastic conduit, good airproof performance, effectively prevents effluent seepage, safety and environmental protection; Inner wall smooth is smooth, and dirt is not easily detained, and reduce the possibility of blocking, emission index strengthens greatly; Pit shaft can scene carry out cutting, perforate, adjustment, adapt to various degree of depth installation requirement, can whole day construction, greatly improve construction speed, effectively reduce costs, construction be fast traditional manhole 10-20 doubly more than.
Current manhole is mostly plane due to bottom, and base is rectangle, and such to arrange bulk strength good not, and the materials of unit volume are more, can not reach the most effective.
Utility model content
The purpose of this utility model is the problems referred to above existed to overcome current manhole, provides a kind of manhole well seat.
In order to reach above-mentioned utility model object, the utility model by the following technical solutions:
A kind of manhole well seat, well seat comprises base and the seat body for being connected with pit shaft, and be connected bottom the seat body that base top adduction and internal diameter are less than base, described base is sphere, chassis interior formation mud sinking chamber; Described base outer wall is provided with some main muscle of warp-wise being extended to base top by base bottom center, and base outer wall is provided with the auxiliary muscle of broadwise arranged in parallel perpendicular to the main muscle of warp-wise, and described base is provided with the arm of draining.
As preferably, described base is the sphere being greater than hemisphere.
As preferably, described base bottom is provided with pallet.
As preferably, described base inner wall be provided with spiral surrounding around muscle.
As preferably, described arm is positioned on mud sinking chamber, and arm is positioned between two adjacent main muscle of warp-wise.
Owing to adopting technique scheme, the beneficial effects of the utility model are:
1 due to base employing spherical structure, and the water in base can scatter equably to the pressure of base, and the intensity of base is increased.
2 spheres have larger unit volume stock utilization to rectangle, thus improve the utilization rate of material, save the energy.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of cross-sectional structure schematic diagram of the present utility model;
Fig. 3 is a kind of vertical section structure schematic diagram of the present utility model.
In figure: 1 base, 2 bodies, 3 mud sinking chambers, the main muscle of 4 warp-wise, the auxiliary muscle of 5 broadwise, 6 arms, 7 pallets, 8 around muscle.
Detailed description of the invention
With specific embodiment, the utility model is further described below.
Embodiment
A kind of manhole well seat, as depicted in figs. 1 and 2, well seat comprises base and the seat body for being connected with pit shaft, be connected bottom the seat body that base top adduction and internal diameter are less than base, described base is sphere, and for being greater than the sphere of hemisphere, chassis interior forms mud sinking chamber; Described base outer wall is provided with some main muscle of warp-wise being extended to base top by base bottom center, base outer wall is provided with the auxiliary muscle of broadwise arranged in parallel perpendicular to the main muscle of warp-wise, as shown in Figure 3, base inner wall be provided with spiral surrounding around muscle, described base is provided with the arm of draining, arm is positioned on mud sinking chamber, and arm is positioned between two adjacent main muscle of warp-wise.
Fix to better base be carried out position, base bottom is provided with pallet.
