Description

Foundation ditch excavation instrument in finite space
Technical Field
The utility model relates to a bucket structure specifically is an instrument that can carry out foundation ditch excavation in finite space.
Background
The cap is the part of the pile-to-column or pier connection. The bearing platform connects several or even more than ten piles together to form a pile foundation. The conventional foundation pit excavation is mainly used for slope excavation, the construction is convenient in the mode, the operation of the excavator is free from great obstacles, and the working efficiency is high. After the foundation is excavated, the foundation structure has large operation space, short construction period and good economic benefit. However, the conditions of the excavation mode are often not allowed to be adopted in the operation and construction in cities or densely populated areas. Excavation of foundation pits of municipal roads or expressways in cities is often carried out in a limited working space, and how to rapidly excavate the foundation pits relates to the overall progress of construction period. Excavation of a foundation pit with a support is vertically and downwards excavated, a large field does not need to be arranged around the foundation pit, the excavation can be used for the situation that the field is narrow and small and the soil quality is poor, and meanwhile, after the underground structure is finished, the backfill workload of the earthwork of the foundation pit is small. In order to reduce urban land occupation and excavation cost as much as possible, the construction method usually reduces the excavation range as much as possible, so that silt in the corners of the steel sheet piles is blocked by pile heads and excavation is not easy to occur.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a novel instrument of practical digging provides more high-efficient, more swift, more convenient the device of digging for the foundation ditch excavation in the finite space.
The utility model provides an adopted technical scheme of its technical problem does: a foundation pit excavation tool in a limited space comprises a bucket body, a base and a connector, wherein the front side of the base is connected with the rear end of the bucket body, the rear side of the base is connected with the connector, and a connecting hole is formed in the connector; the bucket body comprises bottom plate and two blocks of curb plates, two the curb plate symmetry set up in the both sides of bottom plate, the bottom plate is by preceding to the back including digging material portion and flourishing material portion, it is the perk that certain radian makes progress to dig material portion, flourishing material portion is rectangular shape.
Further, the inner curvature of the scooping portion is 50 ° to 80 ° (preferably 70 °), and the outer curvature is 100 ° to 130 ° (preferably 110 °).
Furthermore, a plurality of reinforcing plates are arranged between the bucket body and the base.
Furthermore, the front ends of the two side plates are in a half crescent shape which is matched with the shape of the material digging part and is tilted upwards.
Further, the length-width ratio of the material containing part is not less than 3: 1.
Furthermore, a plurality of digging teeth are arranged at the front end of the digging part.
The utility model has the advantages that:
firstly, the joint is the same as the joint of a common bucket and can be quickly replaced;
secondly, the method is suitable for construction conditions in a narrow range;
and the mechanical construction degree is high, and the construction efficiency is improved.
Drawings
FIG. 1 is a front view of the structure of the present invention;
fig. 2 is a top view of the structure of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the foundation pit excavation tool in a limited space comprises a bucket body 1, a base 3 and a connector 4, wherein the bucket body 1 is a special square pointed bucket with a certain arc shape formed by welding a bottom plate and two side plates, the two side plates are symmetrically welded on two sides of the bottom plate, the bottom plate comprises a material excavating part and a material containing part from front to back, the material excavating part is upwards tilted at a certain radian, wherein the inside bending radian S1 of the material excavating part is 50-80 degrees (preferably 70 degrees), the outside bending radian is 100-130 degrees (preferably 110 degrees), and the inside tilting height H of the material excavating part is not more than the height of the material containing part. The material containing part is rectangular, and the front ends of the two side plates are in a half crescent shape which is matched with the shape of the material digging part and is tilted upwards; the rear end of bottom plate and two blocks of curb plates is connected base 3, and the terminal equipartition of bottom plate and two blocks of curb plates has a plurality of connections reinforcing plate 2 of base 3, the rear side of base 3 is connected with two interval arrangement connector 4, all be equipped with the connecting hole 41 that is used for connecting the digging rod on connector 4.
Further, the length (L) to width (S) ratio of the material containing part is not less than 3: 1, preferably, the length (L) to width (S) ratio of the material containing part is 4.5: 1, and the method is more suitable for construction in a narrow range.
Furthermore, a plurality of digging teeth are arranged at the front end of the digging part.
The above mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still included in the scope covered by the present invention.
